    I have migrated a web application from .net framework 2.0 to 4.0 and I am using Telerik.Web.UI dll with version (2009.1.311.35).In one aspx page 
    when I check the asp:checkbox with AutoPostback="True", I am getting Javascript error Sys.WebForms.PageRequestManager.getInstance()._destroyTree(_3d);) and page do not get postback, I have goggled it and find some blog post for it.


    I do not have RadAjaxManager either on the page or master page which it's use ( But it's there in other pages of application), but I do have the RadComboBox on the same page.
    Can you please tell me is there any workaround available for the version of telerik we are using??
    we have already upgraded to the new version,but for intermediate release we want to ship with old version of telerik only.

    Please suggest.

    Hi Ambuj,

    Please note that the mentioned controls version is not designed for .Net 4.0 framework and we do not guarantee its proper operation in this framework as the control are designed before the framework is invented. Please upgrade your application to the latest official release of RadControl which includes 4.0 version of the dll's and verify how it goes.
