Thank you for writing.
I created a new project and added RadListPicker
, but it seems like it is not enough to reproduce the designer exception that you mentioned. You will help us a lot if you share the exact steps that we need to perform in order to reproduce this behavior (or you can send us a sample project which reproduces it). Also let us know the exact version of the controls that you are using.
