DataGrid.OnBeginningEdit Method

Raises the BeginningEdit event.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

protected virtual void OnBeginningEdit(
	DataGridBeginningEditEventArgs e
)

Parameters

e
Type: System.Windows.Controls.DataGridBeginningEditEventArgs

The data for the event.

This method enables derived classes to prevent the cell from entering edit mode.

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

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