Determines when changes to a data source value get propagated to the corresponding data-bound control property.
The System.Windows.Forms.ControlUpdateMode is used by the Binding.ControlUpdateMode property of the System.Windows.Forms.Binding class. ControlUpdateMode.OnPropertyChanged is the default value. To force a control update when the update mode is ControlUpdateMode.Never, use the Binding.ReadValue method on the related System.Windows.Forms.Binding.
