I know I am not running the most up-to-date version of ACT on my server. (I tried to update it recently and it broke a bunch of things.)
So I want to use a control that I have never used before and I need to look at the reference for the control to be sure I'm using it correctly. But I dont know the exact version I am running.
Where can I find this information?
Right click on the AjaxControlToolkit.dll file and view the properties. The version number there will tell you what version you are using.
