We are not aware of the described issue and, unfortunately, the described information is not enough to determine what is causing it.
Can you please open a new forum thread in the RadPanelBar forum section
in order to avoid inconsistency of this one (being about the RadSplitter control) and provide more details on the issue you are facing? It would be really helpful if you provide the problematic configuration so we can replicate the unwanted behavior on our side.
Thank you for your understanding.
