See the code below generated by Telerik controls ('RadAjaxManager1'
has single quote without backslash)
I dont know, if it has some fix or not. Same code was working in older version of asp.net because telerik does not use setTimeout function there. Why telerik needs setTimeout function with 0 seconds with asp.net 4.0. This is BUG in the telerik RADAJAX control. It will be lot of work for replacing ajax in whole project. I am still looking for solution or workaround, if somebody has found so far ?
