ObjectDataSourceView.OnFiltering(ObjectDataSourceFilteringEventArgs) Method

Definition

Raises the Filtering event before the ObjectDataSourceView object attempts a filtering operation.

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

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(ObjectDataSourceFilteringEventArgs) method in a derived class, be sure to call the base class's OnFiltering(ObjectDataSourceFilteringEventArgs) method for the base class so that registered delegates receive the event.
