This happens because the RadControls
installer actually contains three different assemblies, built targeting specific .NET Framework versions. Two of them (located in the bin20 and bin35 folders respectively) are applicable for use in Visual Studio 2008 and get registered to the ToolBox. The Visual Studio 2008 ToolBox does not provide an interface to filter the items depending on the TargetFramework, which results in the items duplicated. FYI, the ToolBox item filtering is fixed in VS2010.
You can easily have only one RadControls
group if you don't use the other. To do that, please, uninstall RadControls
, then start the installer again and click the Custom
button when asked to choose the setup type. In the next screen, deselect the .NET 20 Components feature (providing you'd use only the .NET35 controls) and continue with the installation.
Let me know if that helps.
