In order to fix the problem, please hide the overflow of the page - if scrollbars are needed, the splitter will generate them:
html, body, form
On a side note, I also prepared the following notes which can help you improve the code further:
- Do not set any sizes to the nested splitters if they are directly nested in a RadPane - when a RadSplitter is directly nested in a RadPane, it automatically resizes itself to occupy 100% of the parent pane. If you set width, height, fullscreenmode, the splitters will make a lot of calculations to resize themselves and this is not necessary and slows down the performance without any benefit.
- when you have a vertical RadSplitter, do not set the Height of the child RadPanes (the same for a horizontal splitter and width) due to the above explained performance consideration
I hope that my reply is helpful, let me know how it goes.
All the best,
the Telerik team
