C# .NET - AJAX Popup Control Extender error - Asked By Henry Taylor on 30-Oct-14 12:26 PM
I have used the Popup Control Extender before and had no problems.
I am now unable to get it to work.
Uncaught TypeError: Cannot read property 'showPopup' of null onmouseover
Uncaught TypeError: Cannot read property 'hidePopup' of null onmouseout
Every time I place my mouse over the control that is supposed to open the popup one of these errors appears in the Chrome browser debug window
I have duplicated this code from a web site where it does work but just can't figure this out.
Has anyone seen this?
Thanks
One thing I noticed is the version of the Ajax Control Toolkit I have used succesfully if 4.1.7.725
The version in this project is 3.5.xxxx
I updated the dll but when I try to Reference it in my project I get the nasty yellow triangle. The framework versions between the working site and the non-working site are the same - 3.5.
Perhaps it is the version of the dll but I can't get it to reference the 4.xxx dll
