ObjectDataSourceView.OnObjectDisposing Method

Definition

Namespace:

System.Web.UI.WebControls

Assembly:

System.Web.dll

Raises the ObjectDisposing event before the ObjectDataSourceView object discards an instantiated type.

protected:
 virtual void OnObjectDisposing(System::Web::UI::WebControls::ObjectDataSourceDisposingEventArgs ^ e);

protected virtual void OnObjectDisposing (System.Web.UI.WebControls.ObjectDataSourceDisposingEventArgs e);

abstract member OnObjectDisposing : System.Web.UI.WebControls.ObjectDataSourceDisposingEventArgs -> unit
override this.OnObjectDisposing : System.Web.UI.WebControls.ObjectDataSourceDisposingEventArgs -> unit

Protected Overridable Sub OnObjectDisposing (e As ObjectDataSourceDisposingEventArgs)

Parameters

e

ObjectDataSourceDisposingEventArgs

An ObjectDataSourceDisposingEventArgs that contains the event data.

Remarks

The OnObjectDisposing is called when the instance of an object that was created to perform a data operation is discarded. The Dispose method is called, only if the type that is identified by the TypeName property implements the IDisposable interface.

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

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