    Original App: Mix of ASP and .Net 2.0 pages using Classic Telerik ASP.NET controls

    Upgraded fine to 3.5 all previous 2.0 pages with Classic controls stilled worked.

    I then copied the v3.5 dll's for WebUI and Charting to the bin and checked out a page that had classic telerik charts and it gave me an error "BC30560: 'ChartTitle' is ambiguous in the namespace 'Telerik.Charting'." A page using Classic RAD Grid still worked without a problem.

    I thought I could run the classic and new controls without issue. What did I do wrong?

    To answer your question first, yes, you can definitely have pages with the classic controls and ASP.NET AJAX controls side-by-side. They've been designed to handle that without issue.

    That said, when upgrading from classic controls to the new ASP.NET AJAX controls, you usually do have to do more than simply changing the assemblies. At the very least, you are usually required to change control tags. More often, though, you need to modify some of the properties of your existing control implementations to address the new APIs of the ASP.NET AJAX-based RadControls. To assist you with that task, you'll articles in the help for every control that guide you through the migration.

    Let me know if that helps solve your problem. If you're still stuck, you may want to open a support ticket so that our support guys can help you quickly fix any side-by-side or upgrade problems.

    Hi guys,

    Indeed, RadControls for ASP.NET AJAX are designed to work flawlessly with RadControls "Classic". RadChart, however, is a bit special due to the code that is shared in Telerik.Charting.dll. You can find more details on this matter in this forum thread.

    Hope this helps.
