Namespace:DevExpress.XtraEditors
Assembly:DevExpress.XtraEditors.v17.2.dll

Expanded Syntax

Expanded Event Data

The following ShowValueEditorEventArgs properties provide information specific to this event.
Property Description
CurrentNode Gets the current node in the FilterControl's tree of criteria.
CustomRepositoryItem Allows you to specify a custom editor to be opened instead of the default one, specified by the Editor property.
Editor Gets the currently processed editor.
FocusedElementIndex Gets the index of the current operand value.
OperandValue Gets the current operand value.
Operation Gets the operation of the current node.

Expanded Remarks

Expanded Example

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E1519.

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.

Expanded Example

The following code shows how to handle the BeforeShowValueEditor event for a FilterControl being used in the Grid Control. This event fires when an editor used to edit an operand value is invoked. In the example, the editor's foreground color is modified.

To subscribe to the BeforeShowValueEditor event when using the FilterControl within the Grid Control, the ColumnView.FilterEditorCreated event is handled.
