Installing the Dec 14 release of the Toolkit (v4.1.7.1213) broke my web application projects. I have worked around some problems, and Identified a few. Using Safari and IE 12, in the following controls and situations:
Problem 1: Any timer control placed on the page causes javascript error "line 2: Error: Object doesn't support this action" during page load. Removing just the timer control avoids the error and the page operates well with the other AjaxToolkit controls that I happen to be using. Other problems I have are with:
Problem 2: The ModalPopupExtender does not work at all (causes the same error as above) if the control uses the four properties for setting up dynamic population of content. MPE controls that don't need the four dynamic content properties work as expected. A workaround for this issue is to use the DynamicPopulateExtender with the analogous property values set to the same values as should work in ModalPopupExtender.
Problem 3: Using the Toolkit with VisualStudio 2010 frequently has problems during compiles, because various files and directories (the entire App_Data, the bin directory, and random others) get copied into the target bin/ directory and often cause failures to compile until deleted. These misplacements of content are recurring frequently. This problem is just an annoyance.
