I am using Visual Studio 2008 with the latest Telerik Winforms. If, for example, I drag a RadTextBox from the toolbox, and click "Edit UI Elements". Then, I choose FillPrimitive and attempt to set SmoothingMode to something like, say, "Invalid" (among other options)
Then immediately Visual Studio would say RadTextBox has thrown an exception in the designer and has been disabled. Error message is "Parameter is not valid" and no stack trace is available. The "element hierarchy editor " dialog is closed and VS hangs with 100% CPU usage (I have to terminate devenv.exe task to recover).
I know this is not a valid use case but should this be handled more gracefully? The exception dialog is OK but at least VS should not hang.

Hello mdanh,
Thanks for writing.
This is a well known limitation of the System.Drawing library. Setting the Smoothing mode to SmoothingMode.Invalid will throw an exception ("Parameter not valid") so, please do not specify this option.
