The CellValueChanging event is raised each time a cell's value is being edited (an end-user types or deletes a character, chooses a value from the dropdown list, etc.). The event provides a parameter whose properties can be used to identify the node and column containing the edited cell, and its current value.
The CellValueChanging event does not fire when changing cell values in code. 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.
After a cell's value has been changed, the CellValueChanged event is raised.
