RadControl Testing Considerations
When writing unit tests it's often convenient to use a RadControl, not as a child of a form, but standalone. This makes for faster performance and simplicity of the test setup and tear-down methods. Whenever a property having an effect on element size or children arrangement is changed explicitly, a request to the layout system is added to the queue of events to be processed. In order to force the processing of this change, the UpdateLayout() method has to be called on the element in question.
