Why isn’t the splitter visible when I run my application?

If the splitter is not distinguishable from the rest of the split container, it is due to the SplitContainerPanels having the same background color as the splitter, and the BorderStyle being set to None. To make the splitter easily recognizable, change the BackColor for the SplitContainerPanels, or set the SplitContainer's BorderStyle.
