It isn't currently possible to hide the scroll-bar in RasterImageList.
Is there something in particular your trying to accomplish with a custom scroll-bar?

There isn't a property to get the actual scroll position. However you could keep track of the position yourself. Just create a Point and decrement and increment the x or y by the amount your scrolling.
As far as detecting when to stop. ScrollItems() goes by rows or column depending if your doing vertical or horizontal scrolling. So you could compare current scroll position to the number of actual rows or columns that exist. You can check the number of Rows and Columns with the TotalColumns and TotalRow properties of RasterImageList.

In the latest version of the SDK we have introduced a new Control for displaying images that also will allow you to hide the scroll bar.
Here is more information about this:
https://www.leadtools.com/help/leadtools/v19/dh/c/leadtools.controls~leadtools.controls.imageviewer~scrollmode.html
ControlSizeMode.Hidden
This instructs the control to enable scrolling
without the use of actual scrollbars. The viewer will not show the
scrollbars no matter what the transformation value is. You can still
manually scroll and pan the image from 0,0 to the maximum allowed (MaximumScrollSize) by using ScrollOffset or ScrollBy. Or if desired, set the value of RestrictScroll to true and scroll or pan the image to any value without restriction.
