DataGrid.OnPreparingCellForEdit(DataGridPreparingCellForEditEventArgs) Method

Definition

Raises the PreparingCellForEdit event.

protected public:
 virtual void OnPreparingCellForEdit(System::Windows::Controls::DataGridPreparingCellForEditEventArgs ^ e);
protected internal virtual void OnPreparingCellForEdit (System.Windows.Controls.DataGridPreparingCellForEditEventArgs e);
abstract member OnPreparingCellForEdit : System.Windows.Controls.DataGridPreparingCellForEditEventArgs -> unit
override this.OnPreparingCellForEdit : System.Windows.Controls.DataGridPreparingCellForEditEventArgs -> unit
Protected Friend Overridable Sub OnPreparingCellForEdit (e As DataGridPreparingCellForEditEventArgs)

Parameters

e
DataGridPreparingCellForEditEventArgs

The data for the event.

Remarks

This method enables derived classes to modify the contents of the cell before it enters edit mode. This method is invoked from DataGridCell (instead of DataGrid) when it has entered edit mode.

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

The OnPreparingCellForEdit 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 OnPreparingCellForEdit(DataGridPreparingCellForEditEventArgs) in a derived class, be sure to call the base class' OnPreparingCellForEdit(DataGridPreparingCellForEditEventArgs) method so that registered delegates receive the event.
