I want to write own Vertical ScrollBar. I found thumbHeight with this code:

C#

float viewableRatio = ViewportHeight / ContentHeight;
thumbHeight = ViewportHeight * viewableRatio;

ViewportHeight : Listbox Visible Height (Height)
ContentHeight : Listbox Height with Items (ItemsHeight * Items.Count)

But I can't found minChange, LargeChange and CurrentValue.

Please help me. I use this scrollbar in Listbox Scrolling. Scrolling be with MouseWheel and MouseDown... If you want, I can send current project. But it's little confused.

Wait your answer, thanks for interesting.. Good Day!

Have you tried to handle the MouseWheel event and, whenever it's fired, move down/up of ItemsHeight?

Becuase I don't think that there are any equivalent of LargeChange and so on like in WinForm
