    HI sangad,

    Welcome to asp.net forum.

    now i update it to 4.0 but i am facing issue of updatepanel the below javascript error come when i use update panel

    As I know, we can use updatepanel control in .net 4.0, here is the introduction to the UpdatePanel Control

    For this issue, you can check your migration procedure first, and check whether it can give some hints why this happens. Here is the reference for you. See: Upgrade an ASP.NET Web Application to ASP.NET 4

    Best regards,

    Angie
