Unable to cast object type error

May 26, 2010 at 1:08 PM

I am running MOSS 2007 w/.Net 3.5 SP1 installed and was able to successfully install this web part, but when I tried adding the web part from the gallery and onto one of my pages, I get the following error in SharePoint.  Is there something else I need to enable/install to support this AJAX-like webpart?  I do have ASP.Net 20 AJAX Extensions 1.0 installed.

I added this like the discussion outlines and I don’t get the error now, but since I added the webpart to one of my pages, I can’t remove it. I created a SharePoint calendar and tried adding this webpart below it and its not working as designed. Am I still missing something here?

I added the assembly info into the web.config which resolved the ‘Unable to cast..’ error. How do I uninstall this web part? Also, does this web part give me the capability to add in links to SSRS reports in the calendar? This is what I’m really trying to accomplish here.
