Filter Elements

You can use Filter Elements to filter the GridControl / TreeListControl's data. Filter Elements are separate controls within your application that automatically retrieve available values, format settings, and other information from the bound control.

Using Filter Elements, you can build your own UI to filter control data. As an example, here is a UI that uses Filter Elements for a filtering panel displayed next to the GridControl:

Expanded Create a Filter Element

  1. Add a filter element (the FilterElement (see FilterElement) class descendants) to the markup.
  2. Set the attached FilterElement.Context property to associate the filter element with the GridControl's filter context.
  3. Specify the field name of the column you want to filter using the FilterElement.FieldName property.

The following code sample uses the CheckedListFilterElement (see CheckedListFilterElement) to filter the GridControl's data by the City column values:
