I am using asp.net ajax calendar extender in my web application. It is showing distorted dates / characters when i open the calendar. I tried to search online to anything similar but can't find it. After opening and closing the calendar control many times, dates disappears and not selectable at all. I am using same calendar extender in another web application on same machine without any issues.

Never faced this issue before. Tried to search online but can't find any solution for this unexpected issue.

Regards

okay i figured this out by updating the Ajax Control Toolkit version to latest available (20.1.0).
