Namespace:DevExpress.XtraGrid.Views.Base
Assembly:DevExpress.XtraGrid.v19.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type FilterControlEventArgs containing data related to this event.

The following FilterControlEventArgs properties provide information specific to this event.
Property Description
Context Provides access to the DevExpress.Data.Controls.ExpressionEditor.ExpressionEditorContext object, which allows you to customize the FilterEditorControl's "Text" tab.
FilterBuilder Gets the form that displays the Filter Control.
FilterControl Gets the Filter Control that displays filter criteria. This property returns null if the ColumnViewOptionsFilter.DefaultFilterEditorView property is set to any value except Visual.
FilterEditor Gets the FilterControl (see FilterControl) (in Visual view mode) or embedded FilterControl (see FilterControl) (in VisualText, TextVisual and Text view modes).
FilterEditorForm
IFilterControl Gets the Filter Control that displays filter criteria.
IFilterEditor Provides access to the currently used Filter Control (FilterControl (see FilterControl) or FilterEditorControl (see FilterEditorControl)) via an interface.
ShowFilterEditor Gets or sets whether to display the Filter Editor (the form that embeds the Filter Editor).

Expanded Remarks

Use the FilterEditorCreated event to customize the Filter Editor, or prevent it from being displayed. The event fires each time the Filter Editor is to be displayed on screen.

Expanded Example

In this example, custom editors are provided to edit value operands in the FilterControl.

The custom editors (SpinEdit and CalcEdit) are supplied by handling the BeforeShowValueEditor event. To supply the editors, corresponding repository items are created and assigned to the event's CustomRepositoryItem parameter.In the example, the FilterControl is used within a GridControl. To get access and subscribe to the FilterControl's BeforeShowValueEditor event, the GridView.FilterEditorCreated event is handled.

The following image shows the result.
