Fires in response to changing the edit value.
public event CellValueChangedEventHandler CellValueChanging
Public Event CellValueChanging As CellValueChangedEventHandler
The CellValueChanging event handler receives an argument of the DevExpress.UI.Xaml.Grid.CellValueChangedEventArgs type.
The CellValueChanging event is raised each time the edited value is being changed (an end-user types or deletes a character, chooses a value from the dropdown list, etc.).
The CellValueChanging event doesn't fire when a cell's value is changed using the methods provided by a data source. Handle this event if you need to provide an immediate response to end-user actions. For instance, you may close the editor and focus the next cell when the edit value's length exceeds the predefined value.
