Overview Zoom Problem

myOverview.Observed = dvDiagram;
myOverview.Stretch = Northwoods.GoXam.StretchPolicy.Uniform;

Or Binding
Observed="{Binding ElementName=myDiagram}"
its not setting the Its not settings the Diagram within Overview bounds.

That’s odd. Are you having any problems with the Overview used in the Org Chart (static) sample? If not, how is your Overview different from the one used in that sample?

Solved problem was I was using different thread to move node position.
