I'm trying to use the Ajaxtoolkit's ModalPopup functionality in a project where I am already using radTreeViews but whenever I add a reference to the DLL I get runtime javascript errors such as 0x800a138f - JavaScript runtime error: Unable to set property 'control' of undefined or null reference
I tried using the Radwindow control, but frankly, I dislike it due to how it doesn't get along with ajax postbacks. I just want to use the ModalPopup control. it's simple and effective.
why can I not have a reference to the telerik.web.ui (v4.0.30319) and have it work when I also include the AjaxContolToolkit dll referenced in my project?
