the biggest issue with thsi seem sot be that in silverlight you can't get a screendump of something that is not in the same domain as the xap you are using.
As noticed in the referenced thread, the workaround might be to use the ProxyUrl property to push the tiles through the proxy so it will look like it comes from the same domain.
Well, I am not sure for how to use ProxyURl property..? any samples or steps how to use Proxypage in silverlight ?
my project is in same domain only but even though i am getting this error ..i tried the best but not getting it exactly how to solve it?
