i am using a split container. For some reason, the splitter looks like this:
It is very hard to see. It is the faint 2 lines in the middle of the two black lines. How do i fix this issue and add a filling between the two lines? I am using Fixed Single as my border style.
Try changing the backcolor, but if using the designer, then also go into Panel1 and Panel2 and change those respective backcolors to the colors you want.
Also, their is a SplitterWidth property that can adjust the overall size of the splitter handle.
Verify that the split container's anchors are set properly.
Use backcolor to change the color.
