Protected Overrides Function PrepareCellForEdit (editingElement As FrameworkElement, editingEventArgs As RoutedEventArgs) As Object

The element that the column displays for a cell in editing mode.

editingEventArgs: RoutedEventArgs

Information about the user gesture that is causing a cell to enter editing mode.

Object

The unedited value.

Remarks

The DataGrid control calls the PrepareCellForEdit method when a cell in a column derived from DataGridColumn enters editing mode. The DataGridCheckBoxColumn class overrides this method to respond immediately to the user gesture by updating the value in the hosted CheckBox control. This immediate response is necessary because a DataGridCheckBoxColumn cell enters edit mode with the same user gesture that changes the state of its hosted CheckBox.
