    Hi All,

    I have just updated AjaxControlToolKit to 3.5.7, I am using VS2008 web application. After updating the dll in my application, I am getting below error on default login page. 

    Microsoft JScript runtime error: Unable to get value of the property 'UI': object is null or undefined

      When I ignores this error, and proceeds for Log in, it doesn't do any thing, even it don't fires any event nothing is working. Need urgent help. Thanks in advance.

    Hi Ajinkya,

    I suggest you use the ToolkitScriptManager instead of the default ScriptManager and set its CombineScripts property to false.

    Hope this helps,
    Shinu.

    Thanks Shinu, I was looking ToolkitScriptManager in asp controls, so it was not getting. I used AjaxToolKit prefix then it worked, issue resolved.
