Create an empty form. Place a RadTabStrip there, and add a new tab. Place a RadComboBox within the newly added tab.
Close the form window, and then re-open it. You will notice that the designer code changes (there is an asterisk indicating the file has changed).
When I look at the designer generated code, I notice that the following line is added
Me.RadComboBox.FormatString = Nothing
If I save, close the form window and re-open, the designer code changes again and the previous line is no longer there. Everytime I close and re-open the form, that line appears and re-appears.
It doesnt make a difference to to the functionality but its annoying that the designer code always changes even if I havent touched the form.
I also notice that there's a slight pause, everytime I re-open the form, it seems to be regenerating the designer code. Does this happen with all forms & controls, or is it a behaviour of the VS2005 designer or is it unique to the Telerik controls?
