I'm trying to set the height-offset of a RadSplitter when the RadRibbonBar is minimized and have tried the code that you suggested, but unfortunately, it doesn't appear to work, since the offset of the splitter doesn't change. If I try to get an alert before and after, then I only get the first alert, not the second.
I am afraid I cannot be of much help as with the current information I can only guess what is the exact configuration in which the issue occurs. I tested the scenario with a sample page setting/removing the height offset when a div element is shown/hidden, but the Splitter behaves as expected on my side. I am attaching my test page to this reply so you can examine it on your side and compare its configuration with the one used by you. I hope this helps.
