Users can filter data using:

  • pop-up menu available for each data row
  • filter panel that allows users to enable/disable/modify a filter, select a filter from the most recently used (MRU) list
  • filter editor that allows users to create filters using a visual constructor or text expressions
  • find panel that allows users to search for data by keywords

You can also filter data in code.


Run the XtraVerticalGrid demo to see the filtering functionality in action.

Expanded Pop-up Filter Menus

A user can click the filter button in a row's header to invoke a pop-up filter menu. This menu contains data values and filters based on the data type.

Use the following properties to access filter options:

Expanded Filter Panel

Once a filter is applied to data, the filter panel is displayed.

The filter panel is only displayed when a filter is applied, and automatically hides otherwise. The VGridOptionsView.ShowFilterPanelMode property specifies the filter panel’s visibility.

The filter panel displays the applied filter. You can handle the VGridControl.CustomFilterDisplayText event to customize the text.

The drop-down button in the filter panel displays a list of recently applied filters. You can disable this functionality or limit the number of items in the list (the default is 7) using the VGridOptionsFilter.AllowMRUFilterList and VGridOptionsFilter.MRUFilterListPopupCount options.

Expanded Filter Editor

In the filter panel, end users can click the Edit Filter button to invoke the filter editor. Set the VGridOptionsFilter.AllowFilterEditor property to false to disable the editor.

The editor provides the visual and text views. The VGridOptionsFilter.DefaultFilterEditorView option allows you to specify the view.


Starting with v18.1, the filter editor allows a user to type filter expressions in the Text tab. This tab supports syntax highlighting and auto-complete. To revert data-aware controls to the legacy filter editor, disable the static WindowsFormsSettings.UseAdvancedFilterEditorControl property.

Expanded How to Filter Data by Multiple Rows from a Single Menu

A row's filter menu shows only values available in that row. To filter data by multiple rows, invoke each row's menu.

It is also possible to group filter values in the current row's filter menu by values in another row. This allows you to filter data for multiple rows from a single menu.


Invoke the "Name" row's filter menu in the XtraVerticalGrid demo to see grouped filters.

To enable this feature, use the row's VGridOptionsRowFilter.PopupExcelFilterGrouping property. This property specifies data fields (rows) by which to group filter values in this row's filter menu. Data fields (rows) should be specified by their names as strings separated by the comma, semicolon, space or tab character.

The code below shows how to display available categories below each trademark as illustrated in the figure above.

You can specify two or more data fields (rows) to group filter values by multiple rows. The field name order determines the group hierarchy. To show available trademarks below each category in the Trademark row's filter menu, you can change the group hierarchy using the following code.

As a result, values from the Category row are shown at the root level.

For a Code First data source, you can use the same syntax in the attribute parameter to annotate data fields with the FilterGroup attribute. See Filtering Attributes to learn more.

Expanded How to Add Custom Functions to Pop-up Menus and the Filter Editor

To create a custom filter function (for example, 'discount is more than 15%'), and add this function to Excel-style pop-up filter menus and the filter editor, do the following:


To add custom functions to filter menus and filter editors of all DevExpress controls in the application, use the static (Shared in VB) CriteriaOperator.QueryCustomFunctions event.

Expanded How to Filter Data in Code

On the grid level, you can specify a filter using the following API:

  • the VGridControl.ActiveFilterString property — gets and sets the active filter as a string expression. This property returns the same value as the ActiveFilter.Expression property.

    See Criteria Language Syntax to learn how to create filter expressions.

  • the VGridControl.ActiveFilterCriteria property — gets or sets the active filter as a CriteriaOperator object. This property returns the same value as the ActiveFilter.Criteria property.

    See Creating Criteria to learn how to create filter criteria.

  • the VGridControl.ActiveFilterEnabled property — allows you to temporarily disable the active filter.

  • the VGridControl.CustomRecordFilter event — allows you to hide a record regardless of the applied filter.
  • the VGridControl.ActiveFilter property — provides access to the filter applied to the grid and the collection of filters applied to particular rows:

    • the indexer — allows you to obtain the filter applied to a particular row. You can also iterate through the collection using the zero-based index.

      The returned filter exposes:

      • Properties — gets the properties (see BaseRow.Properties) of the row to which the filter is applied.
      • Filter — provides access to information about the filter (see RowProperties.FilterInfo). You can use this property to specify a filter at the row level (see below).
    • the NonRowFilterCriteria property — gets or sets a filter which is applied, but not associated with a particular row.

    • the Changed event — fires when a row filter changes.

On the row level, you can specify a filter using the following property:

  • RowProperties.FilterInfo — gets or sets the filter applied to the row.

Expanded Find Panel

The find panel allows users to search for data by keywords. To invoke the panel, press CTRL+F. Type the keywords you are looking for, then press Enter or click Find. See Find Panel to learn more.
