    Hi,

    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,

    Steve.

    Hello Steve,

    Thank you for writing.

    This is a known issue in our TPF. It is already logged in our feedback portal. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - feedback item. The issue is under development and a fix will be released with our next official release. Currently, the only possible workaround is to rename the controls from the VS editor with Find & Replace.
