The semantic of this control is to give the end-user the opportunity to resize SplitPanels contained in RadSplitContainer. I will suggest using RadPanel when you need a control that does not allow resizing. You can add as many panels as you need to make the desired layout. This way the users will not be able to resize the panels.
However, if you want to go with RadSplitContainer, you should hide the splitters. Here is how you can do this:
radSplitContainer1.SplitterWidth = 0;
