SqlDataSourceView.OnFiltering(SqlDataSourceFilteringEventArgs) Method

Definition

Raises the Filtering event before the SqlDataSource control filters the results of a select operation.

protected:
 virtual void OnFiltering(System::Web::UI::WebControls::SqlDataSourceFilteringEventArgs ^ e);
protected virtual void OnFiltering (System.Web.UI.WebControls.SqlDataSourceFilteringEventArgs e);
abstract member OnFiltering : System.Web.UI.WebControls.SqlDataSourceFilteringEventArgs -> unit
override this.OnFiltering : System.Web.UI.WebControls.SqlDataSourceFilteringEventArgs -> unit
Protected Overridable Sub OnFiltering (e As SqlDataSourceFilteringEventArgs)

Parameters

Remarks

Raising an event invokes the event handler through a delegate. For more information about how to handle events, see Handling and Raising Events.

The OnFiltering method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding the OnFiltering(SqlDataSourceFilteringEventArgs) method in a derived class, be sure to call the OnFiltering(SqlDataSourceFilteringEventArgs) method for the base class so that registered delegates receive the event.
