    Hello!
    I upgraded the version of WinForms controls from v.2011.2.11.831 to 2012.2.608.20. In my project, i have a base form which is inherited by many others forms. The problem is that, on different forms, when i open the form designer i get errors for several controls: "Duplicate component name 'controlName'. Component names must be unique and case-insensitive.". In the GAC folders a have the dlls with correct version(2012), in the bin folders i replaced the old dlls and on the reference properties i have the correct version.
    Is there something wrog? I have made the upgrade with the Telerik Upgrade Wizard from Visual Studio 2008.

    I attached a screenshot.

    Thank you!

    Hi Marius,

    I am sorry to hear that you are experiencing upgrade problems.

    After upgrading did you try to build your solution? Can you try rebuilding the solution?

    If this doesn't help I suggest you to open a formal support ticket and send us your project so that we can try to identify the exact reason for the problem.

    All the best,
    Petar

    Thank you for your answer.
    I was able to build the solution. Unfortunately, i can't send the project. Can you tell me what to check?

    This problem can occur for inherited forms based on RadForm controls when an existing project has the Telerik assemblies it needs to compile but the Telerik Controls are not installed in Visual Studio.

    Hello Alan,

    Thank you for sharing your experience. Could you provide some more details regarding your scenario? What do you mean by Telerik Controls are not installed in Visual Studio?

    Regards,

    Note also if your form does not show in the designer, this might be resolved by changing the WindowState property of the Form .
