RadVScrollBar Not Scrolling On Mouse Wheel event

[Dan Harvey]

Hello,

I have a scrollbar on a radform and it works just fine except when you try scrolling using the mouse wheel.  Does anyone have any suggestions? I wasn't sure on how to use the RadVScrollBar1_MouseWheel event.  Please advise.

Thanks,

[Jack]

Hello dan harvey,

Just like the standard MS VScrollBar our scrollbar doesn't scroll on MouseWheel event. However, you can implement this functionality by using a few lines of code:

void radVScrollBar1_MouseWheel(object sender, MouseEventArgs e)
{
    if (e.Delta < 0)
    {
        if (this.radVScrollBar1.Value < this.radVScrollBar1.Maximum)
        {
            this.radVScrollBar1.Value += this.radVScrollBar1.SmallChange;
        }
    }
    else
    {
        if (this.radVScrollBar1.Value > this.radVScrollBar1.Minimum)
        {
            this.radVScrollBar1.Value -= this.radVScrollBar1.SmallChange;
        }
    }
}

I hope this helps. If you have any other questions, don't hesitate to write back.

All the best,
