In a C# aspx page I used a "radTS:RadMultiPage" control (Telerik RadControls 2006). Then I had to format my PC and because of "standarization process" I have to install RadControls 2009 (Q3)...now when I open again this page I have this error: "Error creating control". How can I solve this? 1) Do I have to re-install RadControls 2006 and "live" with both? (2006-2009)....another solution? Thanks!

Hello David,
Based on what you said, I am not sure whether you want to upgrade your old RadControls project to use the Q3 2009 release or not. It is also not clear whether you want to use the ASP.NET AJAX version of the 2009 controls or the "classic" ASP.NET version.
If you don't want to upgrade and keep the old RadControls version in your project, then you only need to ensure that all required assemblies are located in the project's BIN folder or in the GAC.
If you want to upgrade, then you have to do the following:
1. update all RadControls references in the project
2. update all tag prefixes (radTS, radG, etc) to a single tagprefix - e.g. "telerik" or "rad"
3. if you will be using the new RadControls for ASP.NET AJAX, you have to keep in mind that these controls use a different namespace and have different client API. You will have to modify your project accordingly to reflect those changes. Please refer to each control's documentation for more information, e.g.
http://www.telerik.com/help/aspnet-ajax/tab_overviewmigrating.html
If you need further assistance, please send a simple project, so that we can track down the problem.
Sincerely yours,

Hi David,
Please follow the instructions provided by my colleague Dimo in his post and review the individual topics concerning migration of RadControl from Classic to ASP.NET AJAX version. They should help you convert your code and address the design-time issue you are currently facing.
