Visual Studio – trackbar


Recommended Posts

Is there a way to capture all the values of trackbar while sliding the scroll?
Scroll and ValueChanged event are working good in moderate speed.
However if I scroll the slider fast, some values are skipped.
I need in particular that the zero value in the middle of trackbar to be accurately detected.

If it skips over zero, you can check for that. Use Math.Sign() to see if it changed from positive to negative, or vice-versa.


int oldValue = trackBar1.Value;

void trackBar1_Changed(object sender, EventArgs e)
    if (trackBar1.Value == 0 || Math.Sign(trackBar1.Value) != Math.Sign(oldValue))
    oldValue = trackBar1.Value;
