Add a scrollbar for ASP.NET AJAX Modal popup extender inside SharePoint Visual WebPart

I am using the ModalPopUpExtender in Visual WebPart, I need to allow vertical scroll therefore, I set the Panel Property  ScrollBars=”Vertical” as shown:


But unfortunately, the scroll still not working !! as shown below:



In the same Tag I added a Height property and set it to appropriate value like  (590px).


The scroll is now working properly.


Enjoy 🙂
