    I am attempting to create a web form with a RadPivotGrid and RadChart according to http://demos.telerik.com/aspnet-ajax/pivotgrid/examples/applicationscenarios/chartintegration/defaultvb.aspx?show-source=true

    However, I am getting the following error when I run the project:
    JavaScript runtime error: Unable to get property 'PageRequestManager' of undefined or null reference

    Can you kindly advise?

    Hi Erich,

    Could you please elaborate a bit more on the described issue? Do you see it in every browser? We have seen such error in IE and here you can find different resolutions of the problem:
