In This Topic
    ClearAutoFilterValues Field
    In This Topic
    Represents the ClearAutoFilterValues command, which requests that the auto-filter column's AutoFilterValues property be cleared.
    Syntax
    'Declaration
 
Public Shared ReadOnly ClearAutoFilterValues As RoutedCommand
    'Usage
 
Dim value As RoutedCommand
 
value = AutoFilterControl.ClearAutoFilterValues
    public static readonly RoutedCommand ClearAutoFilterValues
    Example
    All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.
    The following example demonstrates how to use a ComboBox as an auto-filter control to automatically filter the content of the ShipCountry column. ComboBox controls do not support multiple selections; therefore, the values of the target column will only be filtered by 1 value. Since, by default, the auto-filter control in the column-manager-cell drop downs support multiple selections, it is recommended to deactivate the drop down by setting the AllowAutoFilter property of the ColumnManagerRow to false to hide the column-manager cells' auto-filter controls and prevent unexpected synchronization behavior between the controls that have the same auto-filter target column or different selection modes.
