TrackBarEx Control Events

[Rouslan Vorobiov]

Hi,
I'm using the TrackBarEx control in my application.I need to trap Scroll event of it but there is no such event.
There is ValueChaged event instead,but this event is not completely suitable for my needs.
Does anybody can advise me how do I solve the problem?

Thank' a lot!

Hi,

I was able to view the condition you have described here. It is not directly possible.

We have a customized class of TrackBarEx that extends to have a ScrollEvent whenever MouseDown/KeyDown is dover over the THUMB.

public class CustomizedTrackBarEx : TrackBarEx
{
protected override void OnKeyDown(KeyEventArgs e)
{
base.OnKeyDown(e);
if (e.KeyData == Keys.Left)
{
RaiseOnScrollChangeEvent(this.Value);
}
}

protected override void OnMouseClick(MouseEventArgs e)
{
base.OnMouseClick(e);
RaiseOnScrollChangeEvent(this.Value);
}
}

Then, add the custom event with the TrackbarEx control,

// creating Custom event
this.trackBarEx1.ScrollChangedValueEvent += new TrackBarScrollEventHanlder(trackBarEx1_ScrollChangedValueEvent);
// Declaration of the custom event
void trackBarEx1_ScrollChangedValueEvent(TrackBarExScrollEventArgs sample)
{
this.trackBarEx1.ButtonColor = Color.FloralWhite;
}

Please take a look at the sample and let me know if it helps.
