OnUpdating Method

LinqDataSourceView.OnUpdating Method (LinqDataSourceUpdateEventArgs)

.NET Framework (current version)
 

Raises the Updating event before the LinqDataSource control performs an update operation.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

protected virtual void OnUpdating(
	LinqDataSourceUpdateEventArgs e
)

Raising an event invokes the event handler through a delegate. For more information, see NIB: Consuming Events.

The OnUpdating method also enables 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 you override the OnUpdating in a derived class, make sure that you call the OnUpdating method for the base class so that registered delegates receive the event.
