How to: Customize Operand Editor Properties in FilterControl

• Oct 25, 2019

The following code snippet handles the FilterControl.ValueEditorShown event to change the foreground color of operand editors in the Data Grid’s embedded Filter Control.

The ColumnView.FilterEditorCreated event is used to subscribe to the ValueEditorShown event.

C#

using DevExpress.XtraEditors.Filtering;
using DevExpress.XtraGrid.Views.Base;

private void gridView1_FilterEditorCreated(object sender, FilterControlEventArgs e) {
    e.FilterEditor.ValueEditorShown += FilterEditor_ValueEditorShown;
}

private void FilterEditor_ValueEditorShown(object sender, ValueEditorEventArgs e) {
    e.Editor.Properties.Appearance.ForeColor = Color.Red;
}

VB.NET

Imports DevExpress.XtraGrid.Views.Base
Imports DevExpress.XtraEditors.Filtering

Private Sub GridView1_FilterEditorCreated(ByVal sender As System.Object, ByVal e As FilterControlEventArgs) _
Handles GridView1.FilterEditorCreated
    AddHandler e.FilterControl.ValueEditorShown, AddressOf FilterControl_ValueEditorShown
End Sub

Private Sub FilterControl_ValueEditorShown(ByVal sender As Object, ByVal e As ValueEditorEventArgs)
    e.Editor.Properties.Appearance.ForeColor = Color.Red
End Sub
