How to get a new value within the OnEditValueChanged or OnChange event handlers

Description:
If I try to obtain the new value from DataController.Values within the OnEditValueChanged event handler it does not work since this property retrieves the previous values in every case. Is there a solution?

Answer:
Applies to:

When the OnEditValueChanged or OnChange event of a column or a row is fired, the new value is not yet posted to the DataController's data array. An in-place editor is still active and you should obtain its editing value. This editor is passed as the Sender parameter of these event handlers. So, please use code similar to the following:

Delphi
procedure TYour_Form.Your_ColumnPropertiesEditValueChanged(  
 Sender: TObject);  
var  
 Edit: TcxCustomEdit;  
 NewValue: Variant;  
begin  
 Edit := Sender as TcxCustomEdit;  
 NewValue := Edit.EditingValue;  
 // Your other code is here...  
end;  

NOTE: When working with text editors (derived from TcxCustomTextEdit), you also can refer to their EditingText and Text properties. However, using EditingValue gives you a more unified approach.
