how to customerize the scalebar?

Question

Hi all,

I want to have a scalebar like this, but right now, I can't find a way to change the style of scalebar in silverlight API.

Basically, I need the scalebar has many values displaying on the top of the scalebar and I want the scalebar to change the units as zoomin or zoomout, say on the state level, it display the unit of miles, when it becomes the county level, it displays the unit of feet.

Any suggestions, thanks very much!

You could change the scalebar displayunit when the map extent changes. Something like (to adapt from your map units and the expected scalebar units): void Map_ExtentChanged(object sender, ExtentEventArgs e) { ScaleBarUnit scaleBarUnit; double width = e.NewExtent.Width; if (width < 10) scaleBarUnit = ScaleBarUnit.Centimeters; else if (width > 100000) scaleBarUnit = ScaleBarUnit.Kilometers; else scaleBarUnit = ScaleBarUnit.Meters; myScaleBar.DisplayUnit = scaleBarUnit; } and XAML Thanks dbroux. I will try this method. btw: how can I change the outlook of the scalebar, just like the image I attached, with different values on the top of the scalebar.
