    Compiler Error Message: BC30560: 'ChartClickEventArgs' is ambiguous in the namespace 'Telerik.Charting'. 

    I keep getting the above error after upgrade from 2008_3_1016_dev to 2008_3_1125.
    It fixed by itself after I click on "Save" a few times in MS visual Studio but error came back again when I made any changes on the page.

    What do I need to do to fix this?

    Hi Den,

    It seems your project is referencing two distinct versions of the Telerik.Charting assembly and that is causing the problem -- probably the register directive in your page for the Telerik.Charting assembly points to the old version that came with the 2008.3.1016 version and you probably have it installed in the GAC. Now you have probably copied the new Telerik.Charting (that came with version 2008.3.1125) in the /bin folder of your application and you need to modify the register directive to reference either the local Telerik.Charting assembly or you can install it in the GAC and reference it from there as well.

    Note, that you also need to update the ChartHttpHandler in your web.config to reference the 1125 version as well.

    If the problem persists and in order to advise you properly we would need you to elaborate on these points:
    • Could you confirm that you have used the RadControls installer or whether you have manually installed Telerik.Charting assemblies in the GAC (if you have run the installer, it has installed the Charting assembly in the GAC automatically). Could you confirm which versions of Telerik.Charting are in the GAC of your workstation machine.
    • Could you send us the ASPX of the offending page and the corresponding project web.config.

    I had the same error just now...
    In my case, I had just forgotten to remove an old telerik charting dll from the bin folder..
    Simply deleting it, stopped the error..
