SqlDataSource.Filtering Event

Occurs before a filter operation.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public event SqlDataSourceFilteringEventHandler Filtering
<asp:SqlDataSource OnFiltering="SqlDataSourceFilteringEventHandler" />

Handle the Filtering event to perform validation operations on filter parameter values before the SqlDataSource control performs a filter operation. You can cancel the Select method by setting the Cancel property of the SqlDataSourceFilteringEventArgs object to true. The event is raised only if the FilterExpression property is set.

The SqlDataSource.Filtering event delegates to the SqlDataSourceView.Filtering event of the SqlDataSourceView object that is associated with the SqlDataSource control.

For more information about handling events, see Consuming Events.
