In IE 7 the table border is displaying when using the RadDatePicker control. I have tried everything to get rid of the border that I can think of or that has been suggested in other forum threads. CSS has no effect whatsoever. I noticed that if I save the html source and set-up the stylesheets and images to be accessible, that the border disappears only when I add border="0" in the table declaration within the div wrapper. The rendered source that I changed is shown below. I left in the hidden input and version comment to give you some context for where to find the issue. I am not sure why this is happening. I am using the Visual Studio 2008 Dynamic Data Entities project and ONLY changing the DateTime_Edit.ascx control to use the RadDatePicker instead of the standard textbox and validators.
