Invoke the Filter Editor

End users can invoke the Filter Editor in the following ways:

  • Right-click anywhere in the field header area and select Show Filter:


  • Click the Edit Filter button ( editfilterbutton ) in the Filter Panel:


To invoke the Filter Editor in code, call the PivotGridControl.ShowPrefilter() method.



The Filter Editor based on the FilterEditorControl and described in this article is introduced in v19.1. Previous versions use the Prefilter Editor based on the FilterControl. To switch to the Prefilter Editor, set the PivotGridControl.UseLegacyFilterEditor property to true.

To remove the Show Filter command from the context menu, set the PivotGridControl.AllowPrefilter property to false.

Customize the Filter Editor


The complete sample project How to Customize a Filter Editor is available in the DevExpress Examples repository.

Use the PivotGridControl.FilterEditorTemplate property to specify a custom data template. You can also use the PivotGridControl.FilterEditorDialogServiceTemplate property to modify the appearance and functionality of the window that hosts the FilterEditorControl. To customize the list of operators, handle the FilterEditorControl.QueryOperators event. The following code demonstrates how to remove all operators except Between and NotBetween:

        <dxfui:FilterEditorControl QueryOperators="FilterEditorControl_QueryOperators" />
using DevExpress.Xpf.Core.FilteringUI;
// ... 
private void FilterEditorControl_QueryOperators(object sender, FilterEditorQueryOperatorsEventArgs e)
    if (e.FieldName == "fieldOrderDate")
        e.Operators.Add(new FilterEditorOperatorItem(FilterEditorOperatorType.Between) { Caption = "Between" });
        e.Operators.Add(new FilterEditorOperatorItem(FilterEditorOperatorType.NotBetween) { Caption = "NotBetween" });
