SqlDataSourceView.OnSelecting(SqlDataSourceSelectingEventArgs) Method


Raises the Selecting event before the SqlDataSource control attempts a data retrieval operation.

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



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

The OnSelecting 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 OnSelecting(SqlDataSourceSelectingEventArgs) method in a derived class, be sure to call the OnSelecting(SqlDataSourceSelectingEventArgs) method for the base class so that registered delegates receive the event.
