Occurs when the System.Web.UI.WebControls.ObjectDataSourceView object discards an instance of an object that it has created.
The ObjectDataSourceView.ObjectDisposing event is raised before the instance of the business object is discarded. If the business object implements the IDisposable interface, the IDisposable.Dispose method is called after The ObjectDataSourceView.ObjectDisposing event is raised.
Handle the ObjectDataSourceView.ObjectDisposing event to call other methods on the object and set properties or to perform clean-up that is specific to the object before the object is destroyed. A reference to the object is accessed by the ObjectDataSourceEventArgs.ObjectInstance property, which is exposed by the System.Web.UI.WebControls.ObjectDataSourceEventArgs object.
If the method that is identified to perform the data operation is static (Shared in Visual Basic), the ObjectDataSourceView.ObjectDisposing event is never raised.
