SqlDataSourceView::OnUpdating Method

Raises the Updating event before the SqlDataSource control attempts an update operation.

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

protected:
virtual void OnUpdating(
	SqlDataSourceCommandEventArgs^ e
)

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

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

The following code example demonstrates how to display data that is retrieved from a Microsoft SQL Server database in a DropDownList control and update the record using a TextBox control. The example shows how you can use a DbTransaction object to add transaction context when using the SqlDataSource control to update data.
