Control for setting MapScale

Question

Dear Gurus!

I would like to implement MapScale control as it done in arcgis Desktop.

I put on View ComboBox , bind SelectedValue of ComboBox  to SelectedMapScale in MapViewModel.

In arcObjects I did this as follows:

axMapControl1.MapScale = SelectedMapScale ;

How to set the desired map scale with  arcgis API for WPF?

There is a ScaleLine control in the toolkit which might help.

There is also a scaleline sample showing how the control can be customized.

I found experimentally approximate coefficient connecting resolution and MapScale. Thus, when SelectedMapScale  changed  I do the following operations:

Map.ZoomToResolution( SelectedMapScale * 0.0002644, mapPoint);
