Rad DatePkr and Rad Combo not working in Ajax Model Popup

[Albert]

On of my btton click event I am opening one panel in model popup (using Ajax popup extender).

Some Rad DatePkrs and Rad Combos are there in the popup.Now when I tried to select Date , at that time that date pkr popup is not opening. 

Com box is also not opening.

If any one knows what is the issue dan please tell me.

-Thanks

I am getting a similiar error.  Has anyone found a solution to this?  I get the error RANDOMLY on a pop-up.
