    After having Designer issues (i hacked the designer)  i removed my UserControl who was the problem; i created a new one wich is the exact (mostly) same UserControl.  But when i  want to create a new RadGridView i'm getting this error:

    Unable to create component 'RadGridView'. 

    'System.Runtime.InteropServices.COMException (0x8004D45); A reference of 'Telerik.WinControls.GridView already existe in the project.

    at VSLangProj.References.Add(String bstrPath)

    at Microsoft.VisualStudio.Design.VSTypeResolutionService.PerformReferenceUpdate(List'1 newReferences)

    at Microsoft.VisualStudio.Design.VSTypeResolutionService.SystemComponentModel.Design.ITypeResolutionService.ReferenceAssembly



    I am using Visual Studio 2013. All my references are present. I tried to create a new Project Telerik ; i'm able to use a RadgridView in the new one.

    Hello Nadir,

    The following article shows how you can solve this: Failed to create component design time exception - Telerik UI for WinForms - KB.

    I hope this will be useful. Let me know if you have additional questions.

    Progress Telerik

    Thanks. That was fast and it works. I used the third solution : i had 2 reference who were not in the same version of others.  I removed them and downloaded different ones.
