Hey Martin,

Thanks for your input

Yes your method works, but doesn’t take a couple if things in to account:

Firstly by setting Slide.Value manually you’ll break any data binding on the Value property -> my designs are usually MVVM, so this isnt a great idea.

Second – if you put a Debug.WriteLine in your value changed handler, you’ll see a non rounded change, then a rounded change – i.e. this method is calling Value twice. (0.951156812339332 then 1)

Third – your method assumes you have access to code behind, which is usually only the case in UserControls, not so much in data templates or CustomControls

I normally really hate inhertiting off controls to do something so simple, but unfortunately I was stuck with the restrictions I listed here.

Once again thanks for sharing your thoughts!

I just did this in the ValueChanged handler:
////
void Slider3_ValueChanged(object sender, RoutedPropertyChangedEventArgs e)
{
Slider3.Value = Math.Round(e.NewValue);
}
////

Seems to work fine
