LinqDataSourceView.OnUpdating(LinqDataSourceUpdateEventArgs) Method

Definition

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

C#
protected virtual void OnUpdating(System.Web.UI.WebControls.LinqDataSourceUpdateEventArgs e);

Parameters

e
LinqDataSourceUpdateEventArgs

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 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(LinqDataSourceUpdateEventArgs) in a derived class, make sure that you call the OnUpdating(LinqDataSourceUpdateEventArgs) method for the base class so that registered delegates receive the event.
