Collapse with Minsize

Hello Kurt,

Thank you for writing.

It is appropriate to use the RadSplitContainer.SplitterMoving event and cancel it considering the SplitterCancelEventArgs.MouseCursorX. Thus, you can control the shrinking of a certain SplitPanel.

I hope this information helps. Should you have further questions, I would be glad to help.
Regards,
