LayerDef Extent

[KeithNightlinger]

I have a dynamic map service with three layers that I am applying a Layer Definition to in code behind based on user input.  After the data is filtered (which is working) I want to pan/zoom to the extent of the visible features. 

using Map.ZoomTo(dmsLayer.FullExtent); takes to the extent of the dynamic map service, not the visible features, nor is there a updated handler for a dynamic map service to try and call after the layer def is completed.

What would be the best way to accomplish this?

Thanks,
Keith

There is no way with the REST API and so with the SL API to get a layer extent taking in care the layer definition.

is there a updated handler for a dynamic map service to try and call after the layer def is completed

No, because the request with a layer def is stateless. It's only used for one exportmap operation.

What would be the best way to accomplish this?

A GP tool or a Server Object Extension (SOE) should be able to accomplish this.
