Properties

ActiveCell

Gets the cell that is being calculated by the Engine.

Declaration

public string ActiveCell { get; }

Property Value

Type	Description
System.String

Remarks

You can use this properly within your custom functions to identify the item in the ICalcData object being computed.

AllowShortCircuitIFs

Gets or sets whether IF function calculations should specifically avoid computing the non-used alternative.

Declaration

public bool AllowShortCircuitIFs { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

The default value is false for code legacy consistency. When AllowShortCircuitIFs is set true, only the necessary alternative of an IF function is computed. To support this behavior, a change in how nested IF function calculations are done is necessary. The default way of calculating nested functions is inside-out, with the inner most functions being computed to a value before the next outer function is evaluated. To support short circuiting IF functions, nested IF functions need to be computed from the outside-in to know what alternative needs to be evaluated. This outside-in calculation pattern only applies to IF functions, and only when AllowShortCircuitIFs is true.

AlwaysComputeDuringRefresh

Gets or sets whether FormulaInfo.calcID is tested before computing a formula during a call to Refresh(String)

Declaration

public bool AlwaysComputeDuringRefresh { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

When a value changes, then the Refresh method is called on any other formula that had a dependency on the changed value. During the Refresh call, the default behavior is to recompute all formulas (AlwaysComputeDuringRefresh = true). If you are using UpdateCalcID() to strictly control when new values should be used, then you should set this property to false. For example, if you are only using PullUpdatedValue(Int32, Int32, Int32) exclusively to retrieve computed values, then setting AlwaysComputeDuringRefresh = false may be more efficient as it will only recompute the value once during the calculations.

CalculatingSuspended

Indicates whether formulas are immediately calculated as dependent cells are changed.

Declaration

public bool CalculatingSuspended { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

Use this property to suspend calculations while a series of changes are made to dependent cells either by the user or programmatically. When the changes are complete, set this property to False, and then call Engine.RecalculateRange to recalculate the affected range. See the sample in GridCellFormulaModel.CalculatingSuspended.

CheckDanglingStack

Gets or sets whether Invalid Formula is returned when the calculation stack is not fully exhausted during a calculation.

Declaration

public bool CheckDanglingStack { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

If you enter a formula like "=(1+2)(9+8)", Essential Calculate will compute this formula as 17, ignoring the dangling 3 value on its calculation stack. If you want this situation flagged as a Invalid Formula, set this CheckDanglingStack property to true. The default value is false for backward compatibility purposes.

ColumnMaxCount

Used with row ranges to possibly provide the upperlimit on the number of columns in the ICalcData object.

Declaration

public int ColumnMaxCount { get; set; }

Property Value

Type	Description
System.Int32

Remarks

Essential Calculate supports column ranges of the form 2:4 as in =SUM(2:4) to represent all cells in rows 2, 3 and 4 from a ICalcData object. To get a value for the number of columns, the CalcEngine first checks to see if the ICalcData object supports the ISheetData interface. If this interface is supported, the column count used to determine the range is obtained through this interface. If the ICalcData object does not support ISupportColumnCount, then the value of ColumnMaxCount is used provided ColumnMaxCount > 0. If not, the fixed value 50 is used.

DependentCells

A read-only property that gets a mapping between a cell and a list of formula cells that depend on it.

Declaration

public Dictionary<object, object> DependentCells { get; }

Property Value

Type	Description
System.Collections.Generic.Dictionary<System.Object, System.Object>

Remarks

The key is the given cell, and the value is a ArrayList of cells containing formulas that reference this cell.

Examples

Here is code that will list formula cells affected by changing the given cell.

public void DisplayAllAffectedCells()
{
	CalcEngine engine = ((GridFormulaCellModel)this.gridControl1.CellModels["FormulaCell"]).Engine;
	foreach(object o in engine.DependentCells.Keys)
	{
		string s1 = o as string;
		Console.Write(s1 + " affects ");
		ArrayList ht = (ArrayList) engine.DependentCells[s1];
		foreach(object o1 in ht)
		{
			string s2 = o1 as string;
			Console.Write(s2 + " ");
		}
		Console.WriteLine("");
	}
}

	Public Sub DisplayAllAffectedCells()
		Dim engine As GridCalcEngine = CType(Me.gridControl1.CellModels("FormulaCell"), GridFormulaCellModel).Engine
		Dim o As Object
		For Each o In  engine.DependentCells.Keys
			Dim s1 As String = CStr(o)
			Console.Write((s1 + " affects "))
			Dim ht As ArrayList = CType(engine.DependentCells(s1), ArrayList)
			Dim o1 As Object
			For Each o1 In  ht
				Dim s2 As String = CStr(o1)
				Console.Write((s2 + " "))
			Next o1
			Console.WriteLine("")
		Next o
	End Sub 'DisplayAllAffectedCells

DependentFormulaCells

A read-only property that gets a mapping between a formula cell and a list of cells upon which it depends.

Declaration

public Dictionary<object, object> DependentFormulaCells { get; }

Property Value

Type	Description
System.Collections.Generic.Dictionary<System.Object, System.Object>

Remarks

The key is the given formula cell and the value is a Hashtable of cells that this formula cell references.

Examples

Here is code that will lists formula cells affected by changing a given cell:

	public void DisplayAllFormulaDependencies()
	{
		GridCalcEngine engine = ((GridFormulaCellModel)this.gridControl1.CellModels["FormulaCell"]).Engine;
		foreach(object o in engine.DependentFormulaCells.Keys)
		{
			string s1 = o as string;
			Console.Write(s1 + " depends upon ");
			Hashtable ht = (Hashtable) engine.DependentFormulaCells[s1];
			foreach(object o1 in ht.Keys)
			{
				string s2 = o1 as string;
				Console.Write(s2 + " ");
			}
			Console.WriteLine("");
		}
	}

	Public Sub DisplayAllFormulaDependencies()
		Dim engine As GridCalcEngine = CType(Me.gridControl1.CellModels("FormulaCell"), GridFormulaCellModel).Engine

		Dim o As Object
		For Each o In  engine.DependentFormulaCells.Keys
			Dim s1 As String = CStr(o)
			Console.Write((s1 + " depends upon "))
			Dim ht As Hashtable = CType(engine.DependentFormulaCells(s1), Hashtable)
			Dim o1 As Object
			For Each o1 In  ht.Keys
				Dim s2 As String = CStr(o1)
				Console.Write((s2 + " "))
			Next o1
			Console.WriteLine("")
		Next o
	End Sub 'DisplayAllFormulaDependencies

EnableLookupTableCaching

Gets or sets whether lookup tables used in the VLookUp and HLookUp functions are cached.

Declaration

public LookupCachingMode EnableLookupTableCaching { get; set; }

Property Value

Type	Description
LookupCachingMode

Remarks

Depending upon your use case, caching look up tables can greatly speed up calculations involving HLookUp and VLookUp. If you make multiple calls to these functions passing in the same look up tables, and if these look up tables are relatively static (don't dynamically change as the look ups are taking place), then caching these tables will likely improve performance.

EnsureIFCallDuringShortCircuit

Gets or sets whether the IF function implementation is called when AllowShortCircuitIFs is true. The default behavior is to not call the IF Function code in the library, but instead, work directly with the IF clauses.

Declaration

public bool EnsureIFCallDuringShortCircuit { get; set; }

Property Value

Type	Description
System.Boolean

ErrorStrings

A property that gets/sets list of # error strings recognized by Excel.

Declaration

public List<object> ErrorStrings { get; set; }

Property Value

Type	Description
System.Collections.Generic.List<System.Object>

ExcelLikeComputations

A property that gets or sets the calculations of the CalcEngine computations to mimic the computations of Excel.

Declaration

public bool ExcelLikeComputations { get; set; }

Property Value

Type	Description
System.Boolean

ForceRefreshCall

Gets or sets whether Refresh(String) must be called on every cells whenever the ValueChanged is triggered. The default value is false.

Declaration

public bool ForceRefreshCall { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

When a value changes, then the Refresh method is called recursively every time the grid_ValuChanged is called. Setting this ForceRefreshCall to false will call Refresh for only those cells where the calculated value is actually modified.

FormulaCharacter

A static property that gets/sets character by which string starts with, can be treated as formula.

Declaration

public static char FormulaCharacter { get; set; }

Property Value

Type	Description
System.Char

FormulaInfoTable

A read-only property that gets the collection of FormulaInfo objects being used by the CalcEngine.

Declaration

public Dictionary<object, object> FormulaInfoTable { get; }

Property Value

Type	Description
System.Collections.Generic.Dictionary<System.Object, System.Object>

GetValueFromArgPreserveLeadingZeros

Gets or sets whether leading zeros are preserved in a call to GetValueFromArg(String).

Declaration

public bool GetValueFromArgPreserveLeadingZeros { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

If the value of arg is "0123" or a cell reference like A1 where A1 holds 0123, then the default behavior is for GetValueFromArg(arg) to return 123, stripping away any leading zeros. If you want calls to GetValueFromArg to preserve the leading zeros, then set GetValueFromArgPreserveLeadingZeros to true.

IterationMaxCount

Gets or sets the maximum number of iterative calls that can be made on a cell. ThrowCircularException will be set to true when you set IterationMaxCount to any value other than zero.

Declaration

public int IterationMaxCount { get; set; }

Property Value

Type	Description
System.Int32

Remarks

Essential Calculate supports an iterative process to solve equations of the form x=f(x). Here you should think of x as being a cell reference like B2 for example. Setting IterationMaxCount to some value other than zero allows the engine to iteratively compute f(x) using the previous iteration's calculated value for x. The initial value is either 0 or the last saved value for a formula in that cell (if the calculation has been performed previously). The iterations continue until either the iteration count exceeds IterationMaxCount, or two successive iteration return values have a relative difference less than IterationMaxTolerance. For example, to have an initial value of 1, you can enter a formula =1 into the cell, and then enter the self referencing formula into the same cell. This will make the iterative calculations start at 1 instead of 0. ThrowCircularException must be set to true in order for the Iterative Calculation support to function For this reason, ThrowCircularException will be automatically set to true when you set a non-zero value to IterationMaxCount. The default value is 0 indicating that iterative calculation support is turned off.

IterationMaxTolerance

Gets or sets the success tolerance used by the CalcEngine's iterative calculation support.

Declaration

public double IterationMaxTolerance { get; set; }

Property Value

Type	Description
System.Double

Remarks

LibraryComputationException

Gets any Exception raised during the computation of a library function provided RethrowLibraryComputationExceptions is set true.

Declaration

public Exception LibraryComputationException { get; }

Property Value

Type	Description
System.Exception

Remarks

Use the ClearLibraryComputationException() method to set this property to null to indicate that there is no pending library exception within the engine.

LibraryFunctions

A read-only property that gets a collection holding the current library functions.

Declaration

public Dictionary<object, object> LibraryFunctions { get; }

Property Value

Type	Description
System.Collections.Generic.Dictionary<System.Object, System.Object>

Remarks

This property gives you direct access to all library functions. The function name serves as the hash key and the function delegate serves as the hash value. The function name should contain only letters, digits or an underscore. You should use the AddFunction(String, CalcEngine.LibraryFunction) method to add functions to this collection. Do not use the Add method inherited from Hashtable. The reason is that the hash key needs to be strictly upper case even though formula syntax is case insensitive with respect to functions names. Using the AddFunction method makes sure the hash key is properly set.

LockDependencies

Gets or sets a value indicating whether editing a cell’s value will update dependent cells.

Declaration

public bool LockDependencies { get; set; }

Property Value

Type	Description
System.Boolean	The default value is False.

Remarks

If enabled, editing a cell's value will not update dependent cells based on the edited value.

MaximumRecursiveCalls

Specifies the maximum number of recursive calls that can be used to compute a cellvalue.

Declaration

public int MaximumRecursiveCalls { get; set; }

Property Value

Type	Description
System.Int32

Remarks

This property comes into play when you have a calculated formula cell that depends on another calculated formula that depends on another calculated formula and so on. If the number of 'depends on another formula' exceeds MaximumRecursiveCalls, you will see a Too Complex message displayed in the cell. The default value is 100, but you can set it higher or lower depending upon your expected needs. The purpose of the limit is to avoid a circular reference locking up your application.

MaxStackDepth

Gets or sets the maximum calculation stack depth.

Declaration

public static int MaxStackDepth { get; set; }

Property Value

Type	Description
System.Int32

Remarks

The default is 50. This is the number of recursive calls that can be made during calculations.

NamedRanges

A property that gets/sets the current named ranges.

Declaration

public Dictionary<object, object> NamedRanges { get; set; }

Property Value

Type	Description
System.Collections.Generic.Dictionary<System.Object, System.Object>

ParseArgumentSeparator

Declaration

public static char ParseArgumentSeparator { get; set; }

Property Value

Type	Description
System.Char

ParseDateTimeSeparator

A static property that gets/sets the character to be recognized by the parsing engine as decimal separator for date.

Declaration

public static char ParseDateTimeSeparator { get; set; }

Property Value

Type	Description
System.Char

ParseDecimalSeparator

A static property that gets/sets the character to be recognized by the parsing engine as decimal separator for numbers.

Declaration

public static char ParseDecimalSeparator { get; set; }

Property Value

Type	Description
System.Char

ReservedWordOperators

Gets or sets a string array that hold the reserved strings that will be used for the OR, AND, XOR, IF, THEN, ELSE and NOT logical operators.

Declaration

public string[] ReservedWordOperators { get; set; }

Property Value

Type	Description
System.String[]

Examples

Here is the code that you can use to define this string array. This code shows the default strings that are used. Note that the string must include a leading and trailing blank, and must be lower case. In formulas that use these operators, the formulas themselves are case agnostic.

engine.ReservedWordOperators = new string[]
{
	" or ",     //0
    " and ",    //1
    " xor ",    //2
    " if ",     //3
    " then ",   //4
    " else ",   //5
    " not "     //6
};

RethrowLibraryComputationExceptions

Gets / sets whether the engine Rethrows any exception raised during the computation of a library function.

Declaration

public bool RethrowLibraryComputationExceptions { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

The default value is false.

RethrowParseExceptions

Gets / sets whether the engine throws an exception when parsing fails with an unknown function error.

Declaration

public bool RethrowParseExceptions { get; set; }

Property Value

Type	Description
System.Boolean

RowMaxCount

Used with column ranges to possibly provide the upperlimit on the number of rows in the ICalcData object.

Declaration

public int RowMaxCount { get; set; }

Property Value

Type	Description
System.Int32

Remarks

Essential Calculate supports column ranges of the form A:D as in =SUM(A:D) to represent all cells in columns A, B, C and D from a ICalcData object. To get a value for the number of rows, the CalcEngine first checks to see if the ICalcData object supports the ISheetData interface. If this interface is supported, the row count used to determine the range is obtained through this interface. If the ICalcData object does not support ISupportRowCount, then the value of RowMaxCount is used provided RowMaxCount > 0. If not, the fixed value 50 is used.

SupportLogicalOperators

Gets or sets whether OR, AND, XOR and IF THEN ELSE logical operators are supported.

Declaration

public bool SupportLogicalOperators { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

The default value is false for backward compatibility.

SupportRangeOperands

Gets or sets whether ranges can be used as binary operands.

Declaration

public bool SupportRangeOperands { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

If this property is true, Essential Calculate recognizes ranges such as B1:B5 and A4:E4 as operands of binary operators. So, if you set the formula = A1:A5 + B1:B5 into cell C4, the calculation will retrieve the values in A4 and B4 to be used in place of the corresponding ranges A1:A5 and B1:B5. Note that such ranges must either have one column wide or one row tall. This fact is used to make the corresponding lookup determined by where the host cell that holds the formula is located. This host cell must either be in the same row or column as some cell in range.

The default value is false.

SupportsSheetRanges

Gets or sets whether sheet range notation is supported.

Declaration

public bool SupportsSheetRanges { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

Excel supports sheet range notation such as = SUM( sheet1:sheet3!A1 ) + Sum( sheet1:sheet3!B1:B4 ). For backward compatibility with earlier versions that did not support this sheet range notation, you can set this SupportsSheetRanges false.

This implementation replaces a sheet range (sheet1:sheet3!B1:B4) with list of ranges (sheet1!B1:B4,sheet2!B1:B4,sheet3!B1:B4).

ThrowCircularException

Gets / sets whether the CalcQuick should throw an exception when a circular calculation is encountered.

Declaration

public bool ThrowCircularException { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

If this property is True, the CalcQuick will throw an exception when it detects a circular calculation. If ThrowCircularException is False, then no exception is thrown and the calculation will loop recursively until Engine.MaximumRecursiveCalls is exceeded.

TreatStringsAsZero

Gets of sets whether the CalcEngine treats nonempty strings as zeros when they are encountered during calculations.

Declaration

public bool TreatStringsAsZero { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

The default value is true meaning that if a nonempty string is encountered during an arithmetic operation, it will be treated as zero.

UseDatesInCalculations

Gets or sets whether dates can be used as operands in calculations. The default value is false.

Declaration

public bool UseDatesInCalculations { get; set; }

Property Value

Type	Description
System.Boolean

UseDependencies

A property that gets / sets whether the CalcEngine should track dependencies.

Declaration

public bool UseDependencies { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

If you are using the CalEngine in a manner where you always call PullUpdatedValue to access the computations, then setting UseDependencies to False will make things more efficient as any requested computed value will be fully computed every time it is retrieved. In this situation, the CalcEngine does not need to track dependencies.

UseFormulaValues

A property that gets/sets whether Formula returns its FormulaValue instead of repeated calculation

Declaration

public bool UseFormulaValues { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

Use this property to return the FormulaValue when a cell contain more depency cells.

ICalcData	data	ICalcData object that holds the data to be recalculated.

Remarks

The calculations for non-visible formula cells are performed the next time cell are actually displayed. If you want the calculation performed immediately on cells (visible or not), call the two argument overload of RecalculateRange, passing the forceCalculations argument as True.

RefreshRange(RangeInfo)

Recalculates every cell that depends upon any cell in the passed-in range.

Declaration

public void RefreshRange(RangeInfo range)

Parameters

Type	Name	Description
RangeInfo	range	RangeInfo object to be refreshed.

Remarks

For example, if range is RangeInfo(1,1,2,2), and cells (5,6) and (12,17) hold formulas that reference the cells in the range, then cells (5,6) and (12,17) will be re-computed as the result of this call.

RegisterGridAsSheet(String, ICalcData, Int32)

RegisterGridAsSheet is a method that registers an ICalcData object so it can be referenced in a formula from another ICalcData object.

Declaration

public void RegisterGridAsSheet(string refName, ICalcData model, int sheetFamilyID)

Parameters

Type	Name	Description
System.String	refName	The reference name used to refer to this ICalcData object from formulas in other ICalcData objects.
ICalcData	model	The ICalcData from the ICalcData object being registered.
System.Int32	sheetFamilyID	An integer previously created with a call to CalcEngine.CreateSheetFamilyID. This number is used to identify the ICalcData objects as belonging to a particular family of ICalcData objects. You can only reference ICalcData objects from within the same family.

Remarks

Essential Calculate supports multisheet references with its formulas. For example, if you have two ICalcData objects, then you can reference cells from the first ICalcData object in the second ICalcData object. For this to work, both ICalcData objects need to be registered using this method. The syntax for using a sheet reference as part of a formula is to prefix a cell reference with the sheet reference name followed by an exclamation point. The formula "= sheet1!A1 + sheet2!C3" would add the value is cell A1 for the ICalcData object whose reference name is sheet1 to the value from cell C3 in the ICalcData object whose reference name is sheet2.

Examples

Use this code to use cross sheet references:

	//Register three ICalcData objects so cell can be referenced across ICalcData objects:
	int sheetfamilyID = CalcEngine.CreateSheetFamilyID();
	myCalcEngine.RegisterGridAsSheet("summary", calcData1, sheetfamilyID);
	myCalcEngine.RegisterGridAsSheet("income", calcData2, sheetfamilyID);
	myCalcEngine.RegisterGridAsSheet("expenses", calcData3, sheetfamilyID);
	....
	//Sample formula usage for cells in calcData1, the 'summary' data source.
	//This code sums ups some cells from calcData3, the 'expenses' data source
	//and calcData2, the 'income' data source.
	//Sum the range B2:B8 from expenses:
	string sumExpenses = "= Sum(expenses!B2:expenses!B8)";
	//Sum the range B2:B4 from income:
	string sumIncome = "= Sum(income!B2:income!B4)";

	'Register three ICalcData objects so cell can be referenced across ICalcData objects:
	Dim sheetfamilyID As Integer = CalcEngine.CreateSheetFamilyID();
	myCalcEngine.RegisterGridAsSheet("summary", calcData1, sheetfamilyID)
	myCalcEngine.RegisterGridAsSheet("income", calcData2, sheetfamilyID)
	myCalcEngine.RegisterGridAsSheet("expenses", calcData3, sheetfamilyID)
	....
	'Sample formula usage for cells in calcData1, the 'summary' data source.
	'This code sums ups some cells from calcData3, the 'expenses' data source
	'and calcData2, the 'income' data source.
	'Sum the range B2:B8 from expenses:
	Dim sumExpenses As String = "= Sum(expenses!B2:expenses!B8)"
	'Sum the range B2:B4 from income:
	Dim sumIncome As String = "= Sum(income!B2:income!B4)"
