Customizing legend based on visible symbology

Question

Hi there,

I have three layers with extensive symbologies that need to be present as part of a printable map legend in a web map. There is never a point where all of the symbols for all of the layers are present in the same view extent, so constraining the legend to only show currently-visible features seems to be a good solution to the "too much information" problem I am facing here.

I know that there is a way on the desktop to only show classes that are visible in the current map extent, but I can't seem to find an equivalent for online development. Does anyone know of a custom solution that I can implement in Silverlight?

Thank you very much for your time in advance!

Same Problem. Did you ever find a solution to this?

Can limit features to map extent using a Feature Layer in OnDemand mode but it always gets the entire set of classes to populate the legend.

Thanks ...
