Class CalcSheet

CalcSheet represents a single worksheet in a workbook.

Inheritance

System.Object

CalcSheet

Implements

ISheetData

ICalcData

Namespace: Syncfusion.OfficeChart.Calculate

Assembly: Syncfusion.OfficeChart.Portable.dll

Syntax

public class CalcSheet : Object, ISheetData, ICalcData

Remarks

A CalcSheet plays the role of an Excel Worksheet. It maintains its own internal data object to hold FormulaInfo objects used by the CalcEngine in its calculation work. The CalcSheet accesses the raw data / formulas that you want to use in the calculations via the ICalcData interface.

OnCalculatedValueChanged(ValueChangedEventArgs)

Raises the CalculatedValueChanged event.

Declaration

protected virtual void OnCalculatedValueChanged(ValueChangedEventArgs e)

Parameters

Type	Name	Description
ValueChangedEventArgs	e	Includes the row, col, and value of the change.

Remarks

This event should be raised any time a value changes.

OnValueChanged(ValueChangedEventArgs)

Raises the ValueChanged event.

Declaration

protected virtual void OnValueChanged(ValueChangedEventArgs e)

Parameters

Type	Name	Description
ValueChangedEventArgs	e	Includes the row, col, and value of the change.

Remarks

ReadSSS(StreamReader)

Creates a CalcSheet object from the content of a StreamReader.

Declaration

public static CalcSheet ReadSSS(StreamReader sr)

Parameters

Type	Name	Description
System.IO.StreamReader	sr	The StreamReader.

remove_CalculatedValueChanged(ValueChangedEventHandler)

Declaration

public void remove_CalculatedValueChanged(ValueChangedEventHandler value)

Parameters

Type	Name	Description
ValueChangedEventHandler	value

remove_ValueChanged(ValueChangedEventHandler)

Declaration

public void remove_ValueChanged(ValueChangedEventHandler value)

Parameters

Type	Name	Description
ValueChangedEventHandler	value

SetValue(Int32, Int32, String)

A Virtual method to save the value through the ICalcData.SetValueRowCol implementation method and raise the ValueChanged event.

Declaration

public virtual void SetValue(int row, int col, string val)

Parameters

Type	Name	Description
System.Int32	row	The row index, one-based.
System.Int32	col	The column index, one-based.
System.String	val	The value.

SetValueRowCol(Object, Int32, Int32)

A Virtual method to set a value at a given row and column.

Declaration

public virtual void SetValueRowCol(object value, int row, int col)

Parameters

Type	Name	Description
System.Object	value	Value to be set.
System.Int32	row	One-based row index.
System.Int32	col	One-based column index.

WireParentObject()

A Virtual method that can be used to handle subscribing to any base object events necessary for implementing the ValueChanged event.

Declaration

public virtual void WireParentObject()

Remarks

For example, when implementing ICalcData on a DataGrid-derived object, you need to know when something in the DataGrid changes so you can raise the required ICalcData.ValueChanged event. In WireParentObject, the DataGrid can subscribe to its DataSource's change event to handle this requirement. If the DataSource is a DataTable, then the DataTable.ColumnChanged event can fulfill the requirement.

WriteSSS(StreamWriter)

Writes this CalcSheet object with formulas serialized to the given StreamWriter.

Declaration

public void WriteSSS(StreamWriter sw)

Parameters

Type	Name	Description
System.IO.StreamWriter	sw	The StreamWriter.

WriteSSS(StreamWriter, Boolean)

Writes this CalcSheet object to the given StreamWriter.

Declaration

public void WriteSSS(StreamWriter sw, bool valuesOnly)

Parameters

Type	Name	Description
System.IO.StreamWriter	sw	The StreamWriter.
System.Boolean	valuesOnly	Indicates whether to serialize formulas (False) or computed values (True).

Events

This event is raised in SetValueRowCol.

Declaration

public event ValueChangedEventHandler CalculatedValueChanged

Event Type

Type	Description
