Class GridEngine

The engine lets you set the main datasource for the whole engine. The TableDescriptor will pick up the ItemProperties (schema information) from the datasource and the table will be initialized at run-time with records from the list.

Syntax
public class GridEngine : GridEngineBase, ICustomTypeDescriptor, ITableEventsTarget, IComponent, IDisposable, IGridTableCellAppearanceSource, IGridGroupOptionsSource, IGridTableOptionsSource, ISupportInitialize
Remarks

The TableDescriptor is browsable. You can modify its collections and properties in the designer.

By default, TableDescriptor is auto-populated. If you do not modify its settings and later change the datasource, it will be automatically reinitialized. If you have made modifications to the TableDescriptor and changed the SourceList, the modifications will be kept. To discard modifications of a TableDescriptor, you need to explicitly call ResetTableDescriptor.

The Table is dependent on information provided by the TableDescriptor and the records from SourceList. It is created on the fly and can not be designed with designer.

The GridEngine class adds the plumbing for displaying the data in a GridGroupingControl. You can specify the datasource using the DataSource and DataMember properties through the designer.

Properties

AllowCacheStyles

Gets or sets the value that whether indicating the flag is enable if you want GridRecordRow and GridCaptionRow elements to keep a cache with style information for individual cells and reduce the number of QueryCellStyleInfo calls being raised for this cell.

Declaration
public bool AllowCacheStyles { get; set; }
Property Value
Type
System.Boolean
Remarks

When you enable this property, the CreateRecordRow(RecordRowsPart) and CreateCaptionRow(CaptionSection) methods will instantiate derived GridRecordRowWithCache and GridCaptionRowWithCache elements that implement the IGridTableCellStyleCache interface.

If other elements should support caching, you can add support for caching by deriving a class from the elements base class and implement the IGridTableCellStyleCache interface. See the GridRecordRowWithCache implementation how to do this.

Appearance

Gets or sets the default GridTableCellAppearance with default GridTableCellStyleInfo information for all cell elements in the control. This property lets you control almost any aspect of the appearance of the grouping grid like cell background color, font, or the cell type.

Declaration
public GridTableCellAppearance Appearance { get; set; }
Property Value
Type
GridTableCellAppearance

AppearanceVersion

Gets or sets the version of the Appearance object. This number is increased each time a property in the Appearance object is changed.

Declaration
public int AppearanceVersion { get; set; }
Property Value
Type
System.Int32

BaseStyles

Maintains a collection of base styles. Users can add BaseStyles to the engine (also in design-time) and then inherit style settings through the GridStyleInfo.BaseStyle property in GridTableCellStyleInfo property of GridTableCellAppearance.

Declaration
public GridTableBaseStyleCollection BaseStyles { get; set; }
Property Value
Type
GridTableBaseStyleCollection

BlinkTime

Gets or sets the time in milliseconds how long to highlight values in a record after a change was detected. The engine will highlight a cell for the specified period in milliseconds if the value was increased or decreased. If set to 0 the feature is disabled.

Declaration
public int BlinkTime { get; set; }
Property Value
Type
System.Int32

ChildGroupOptions

Lets you control the look of inner groups like whether the Caption Row is visible, or what CaptionText is.

Declaration
public GridGroupOptionsStyleInfo ChildGroupOptions { get; set; }
Property Value
Type
GridGroupOptionsStyleInfo

DefaultAppearance

Gets default appearance settings for the grid at runtime. These settings will not be serialized or written to good and can be used if you want to specify default settings for a derived GridGroupingControl. Any appearance element in the engine will inherit these settings.

Declaration
public GridTableCellAppearance DefaultAppearance { get; }
Property Value
Type
GridTableCellAppearance

DefaultBaseStyles

Maintains a collection of default base styles which are not serialized to xml or code. End users can override the base styles by manually adding a base style with the same name to the BaseStyles collection.

Declaration
public GridTableBaseStyleCollection DefaultBaseStyles { get; }
Property Value
Type
GridTableBaseStyleCollection

GroupDropArea

Used internally. Gets or sets the value that indicating whether the visibility of GroupDropArea from ParentControl.

Declaration
public bool GroupDropArea { get; set; }
Property Value
Type
System.Boolean

GroupingControl

Gets the GridGroupingControl that hosts this engine.

Declaration
public GridGroupingControl GroupingControl { get; }
Property Value
Type
GridGroupingControl

Initializing

Gets the value that Determines if BeginInit() was called.

Declaration
public bool Initializing { get; }
Property Value
Type
System.Boolean

InsertRemoveBehavior

Gets or sets it's specifies how the grid should react if records are inserted or deleted.

Declaration
public GridListChangedInsertRemoveBehavior InsertRemoveBehavior { get; set; }
Property Value
Type
GridListChangedInsertRemoveBehavior

InsertRemoveBehaviorWithEndEdit

Gets or sets specifies how the grid should react if records are inserted or deleted through direct user interaction with AddNew record.

Declaration
public GridListChangedInsertRemoveBehavior InsertRemoveBehaviorWithEndEdit { get; set; }
Property Value
Type
GridListChangedInsertRemoveBehavior

InvalidateAllWhenListChanged

Gets or sets the value that indicating whether the grid should simply call Invalidate when a ListChanged event is handled or if it should determine the area that is affected by the change and call InvalidateRange. With version 4.4 check also the InsertRemoveBehavior and SortPositionChangedBehavior properties.

Declaration
public bool InvalidateAllWhenListChanged { get; set; }
Property Value
Type
System.Boolean
Remarks

On first sight, you might think it better to determine the area that is affected by a change and call InvalidateRange. But when calling InvalidateRange, the grid needs to know the exact position of the record in the table before it can mark that area dirty. In order to determine the record position (and y-position of the row in the display), counters need to be evaluated. This operation can cost more time than simply calling Invalidate in high-frequency update scenarios.

Also, be aware that the group caption bar needs to be updated when a record changes.

With version 4.4 check out the new InsertRemoveBehavior and SortPositionChangedBehavior properties and the UpdateDisplayFrequency properties that will speed up things a lot if InvalidateAllWhenListChanged = false.

NestedTableGroupOptions

Gets or sets the style info for the child group option. Lets you control the look of the topmost group of nested tables such as whether the Caption Row is visible or what CaptionText is.

Declaration
public GridGroupOptionsStyleInfo NestedTableGroupOptions { get; set; }
Property Value
Type
GridGroupOptionsStyleInfo

ParentControl

Gets the GridGroupingControl that hosts this engine.

Declaration
public GridGroupingControl ParentControl { get; }
Property Value
Type

PropertyTypeDefaultStyles

A collection of GridPropertyTypeDefaultStyle with default GridTableCellStyleInfo information for RecordFieldCell elements based on the columns System.Type. Each basic type has default style information registered with this collection.

Declaration
public GridPropertyTypeDefaultStyleCollection PropertyTypeDefaultStyles { get; }
Property Value
Type
GridPropertyTypeDefaultStyleCollection
Remarks

The collection contains pre-defined settings such as HorizontalAlignment for numbers and cell type (e.g. check box for boolean).

GridPropertyTypeDefaultStyle settings have less precedence in styles inheritance than Appearance styles.

Note: Changes you make to this collection do not get serialized; you will need to reapply any changes even if you read back the schema from an XML file.

SortPositionChangedBehavior

Gets or sets it's specifies how the grid should react if the sort position of a record records changes.

Declaration
public GridListChangedInsertRemoveBehavior SortPositionChangedBehavior { get; set; }
Property Value
Type
GridListChangedInsertRemoveBehavior

Events

ParseCommonFormats

Use this event to provide support for parsing the formatted string and convert it into the the underlying cell's value considering Format and CellValueType.

This event is raised from GridCellModelBase.ApplyFormattedText after SaveCellFormattedText was raised. The event is raised only if the SaveCellFormattedText did not set e.Handled.

Declaration
public event GridCellTextEventHandler ParseCommonFormats
Event Type
Type
GridCellTextEventHandler
Remarks

The grid has built-in support for parsing the Percent format (Format = "P") and Hexadecimal format (Format = "X"). You should handle this event if you want to add support for other formats.

GridCellTextEventArgs has information about the style settings of the cell. You can inspect that style to get information about Format and CellValueType of the cell.

QueryAddColumn

The GridEngine.QueryAddColumn event affects the auto-population of the GridColumnDescriptorCollection.

It is called for each column and lets you control at run-time if the column should be added to the GridColumnDescriptorCollection. You can set e.Cancel = True to avoid specific columns being added.

Declaration
public event GridQueryAddColumnEventHandler QueryAddColumn
Event Type
Type
GridQueryAddColumnEventHandler
Remarks

Handling through a GridQueryAddColumnEventArgs

QueryAddVisibleColumn

The QueryAddVisibleColumn event affects the auto-population of the GridVisibleColumnDescriptorCollection.

It is called for each column and lets you control at run-time if the column should be added to the GridVisibleColumnDescriptorCollection. You can set e.Cancel = True to avoid specific columns being added.

Declaration
public event GridQueryAddVisibleColumnEventHandler QueryAddVisibleColumn
Event Type
Type
GridQueryAddVisibleColumnEventHandler
Remarks

Handling through a GridQueryAddVisibleColumnEventArgs

QueryCellFormattedText

Occurs each time the FormattedText is called to get the formatted string that represents the underlying cell's value considering Format.

Declaration
public event GridCellTextEventHandler QueryCellFormattedText
Event Type
Type
GridCellTextEventHandler
Remarks

This event allows you to customize how to format a cell's value as string at run-time on demand based on Format.

If you do want to customize the grid's default formatting, you should assign the resulting string to Text and set Handled to True. The grid will check this flag to see whether it should return Text or use a default formatting routine.

If you need identity information about the cell such as row and column index, you can get that information by querying the CellIdentity of the Style object.

See Also
ApplyFormattedText(GridStyleInfo, System.String, System.Int32)

QueryCellStyleInfo

Occurs for each cell before a GridTableControl starts painting and lets users customize the display of cells.

Declaration
public event GridTableCellStyleInfoEventHandler QueryCellStyleInfo
Event Type
Type
GridTableCellStyleInfoEventHandler

QueryCellText

Occurs each time the Text is called to get the raw string that represents the underlying cell's value.

Declaration
public event GridCellTextEventHandler QueryCellText
Event Type
Type
GridCellTextEventHandler
Remarks

This event allows you to customize how to represent a cell's value as string at run-time on demand.

If you do want to customize the grid's default conversion, you should assign the result string to Text and set Handled to True. The grid will check this flag to see whether it should return Text or use a default conversion.

If you need identity information about the cell such as row and column index, you can get that information by querying CellIdentity of the Style object.

See Also
GetText(GridStyleInfo, System.Object)

QueryCoveredRange

Occurs to determine if the cell belongs to a covered range and returns the covered range of the cell or the cell itself as GridRangeInfo if it is not a covered range.

Declaration
public event GridTableQueryCoveredRangeEventHandler QueryCoveredRange
Event Type
Type
GridTableQueryCoveredRangeEventHandler

QueryCustomSummary

Occurs for each GridSummaryColumnDescriptor before the SummaryDescriptor is determined. You must handle this event if you specified Custom as SummaryType.

Declaration
public event GridQueryCustomSummaryEventHandler QueryCustomSummary
Event Type
Type
GridQueryCustomSummaryEventHandler

SaveCellFormattedText

Occurs each time the FormattedText is called to parse the formatted string that represents the underlying cell's value considering Format and CellValueType.

Declaration
public event GridCellTextEventHandler SaveCellFormattedText
Event Type
Type
GridCellTextEventHandler
Remarks

This event allows you to customize how to parse the formatted text into a cell value at run-time on demand.

If you do want to customize the grid's default parsing behavior, you should assign the resulting value to the CellValue of the GridStyleInfo object and set Handled to True. The grid will check this flag to see whether it should accept your modification or use a default parsing routine.

If you need identity information about the cell such as row and column index, you can get that information by querying the CellIdentity of the Style object.

This event is normally called from within GridStyleInfo, which is called when the user enters text into a text box or when text is assigned to FormattedText. ApplyFormattedText method checks if there are event handlers for SaveCellFormattedText and if the Handled is not set, they try to convert the input text into the type specified with CellValueType.

If this conversion fails, ApplyFormattedText(GridStyleInfo, String, Int32) will check StrictValueType. If it is True, an exception is thrown which itself results in a warning message displayed to the user at the time from CurrentCellValidating.

If you set StrictValueType to False, ApplyFormattedText(GridStyleInfo, String, Int32) will not throw an exception and simply store the text as CellValue.

If you need a more specialized customization of this behavior, you should handle the SaveCellFormattedText event. This lets you parse the text input and change the cells CellValueType at run-time. See the attached example.

Examples

This example parses the text input and changes the cell's CellValueType at run-time if the input does not match the current CellValueType.

SaveCellText

Occurs each time the Text is called to set the unformatted string that represents the underlying cell's value.

Declaration
public event GridCellTextEventHandler SaveCellText
Event Type
Type
GridCellTextEventHandler
Remarks

This event allows you to customize how to parse the unformatted text into a cell value at run-time on demand.

If you do want to customize the grid's default parsing behavior, you should assign the resulting value to the CellValue of the GridStyleInfo object and set Handled to True. The grid will check this flag to see whether it should accept your modification or use a default parsing routine.

If you need identity information about the cell such as row and column index, query the CellIdentity of the Style object.

See the SaveCellFormattedText event for further discussion since these two events are very similar. Often you will need to handle both events in your code in the same way.
