Hello!

I am using Telerik ASP.NET AJAX. When i update/insert, through User control (ACSX) in my parent page, algo a user control, the form loads full of bugs, giving me this exception:

Uncaught TypeError: a.beginUpdate is not a function
at Sys.Component.create ()
at Array. (Default.aspx:1504)
at ScriptResource.axd

I'm clueless about the issue, any ideas?

Try to use the latest version of Telerik for ASP.NET and recompile your code and test it works or not.
