Scrolling is independent for each split. Often, you need to prevent one or more columns from scrolling horizontally or vertically so that they will always be in view. List for WinForms provides you with an easy way to keep any number of columns from scrolling at any location within the list (even in the middle!) by setting a few split properties.
As an example, assume that you have a list with three horizontal splits. The following code will "fix" columns 0 and 1 in the middle split:

Usually, if you keep columns 0 and 1 from scrolling in one split, you will want to make them invisible in the other splits:
