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

e: SqlDataSourceFilteringEventArgs

A SqlDataSourceFilteringEventArgs that contains the event data.

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.
