It often occurs that our controls run fine in a blank page, but run into some problems when putting in a page that already has many other some contents/code. In this case the problem most likely has to do with the contents/code in your page, for example, an CSS style that interferes with our product, some code behind that incorrectly set certain properties, etc.

The easiest way to troubleshoot this problem is to comment out code/content block by block until the problem disappears. This way you can easily find out the triggering part. Once you know the triggering part, why the problem occurs might become very clear.

If you know the triggering part but can not explain why it would a trigger a problem, please create a test page based on your stripped down page. Make sure the test page runs and demonstrates the problem. Post the test page and we will take a look as soon as possible.
