we got a pretty infuriating problem with Telerik for WinForms. We don't know why but the project started to producing errors when renaming RadControls: "Property value is not valid." (see attached screenshot). The renaming is still done, but the code for the old name is still left behind in the designer. So if I add a checkbox, it gets the name "radCheckBox1" and rename it to "radCheckBoxUser", the error will pop up and code for both will stay in the designer code. Also, if I create an event via the property window in VS for radCheckBoxUser, it will still reference the old checkbox and create a "radCheckBox1_ToggleStateChanged" event. So almost every time we add or change a control, we have to clean up designer code and code behind, which is too time consuming.
Can anybody give us a clue as to why this behavior occurs and help us to solve this problem? It would be really appreciated.
Thanks and regards,
