Note that RadForm is not intended to handle this particular case in any specific manner. As I have already mentioned, RadForm inherits from the standard Windows Forms. This is why any working solution that is applicable to standard Windows Form is relevant to RadForm as well.
Note that this is more like a general programming question and it is not directly related to RadForm. Feel free to search in the relevant forums if you have any further questions on this topic.
Should you have further questions regarding RadControls from the Telerik UI for WinForms suite please let me know.
