Hi Bobby Owens,
I am not quite sure what your scenario is, but in case you are setting new size to one of the RadPanes using its set_width, the problem is that by doing so, you only change the width of this one pane. In case you want to resize that pane to a certain width, you should you the resize method of the RadPane instead. For additional information on the client API of the RadPane client object, please refer to our online documentation
In case this information does not help you, please provide the code of a simple test page that demonstrates the result you get as well as detailed information on the expected result.
