Hi everyone,
I was working on a web form and i'm using vs 2012...I added an extender to my textbox for a calendar control and i also added requiredfieldvalidation to it and when i go to compile i am getting these errors...
0x800a138f - JavaScript runtime error: Unable to get property 'UI' of undefined or null reference
and it brings me to this line...
$create(Sys.Extended.UI.CalendarBehavior, {"id":"TbExpiryDate_CalendarExtender"}, null, null, $get("TbExpiryDate"));
I was able to see the stack but i can't get to the stack now...I had found solutions online to add a key to my web config but it still wouldn't work and I'm wondering if anyone knows what this means and how i can fix it.
Thanks
