禁用DevExpress XtraScrollableControl的鼠标滚轮滚动

Question

I dont want my XtraScrollableControl to scroll using mouse wheel. But scroll should be enabled and visible and I should scroll XtraScrollableControl using mouse drag. If i set

xtraScrollableControl1.AutoScroll = false;

the scroll bars are not visible anymore and if I set

xtraScrollableControl1.FireScrollEventOnMouseWheel = true

then nothing happens.I am using DevExpress 13.2.5

Answer 1

It looks like DevExpress may have a solution for this in their KB:

Take a look and see if that meets your needs. I was going to try to replicate the problem and the suggested fix, but I can't figure out what a "Scrollable Control" is. Can you point me to that specific control?

Answer 2

It seems that the only way is to create XtraScrollableControl descendant and override its OnMouseWheelCore method with no code on it.
Here is example:

public class NoMouseWheelControl : XtraScrollableControl
{
    protected override void OnMouseWheelCore(MouseEventArgs ev)
    {
        //No more wheel.
    }
}
