Zooming to Available features.

Hello,
I have a combobox which i use to filter features depending on a field value.

Im using the Where property of the Featurelayer to filter features, after that i call the Update method.

now i want to zoom/set the view to the available results of the where property, any way to do that?

I tried the following:
layer.Where = where;
Map.Extent = layer.FullExtent;
layer.Update();

it works sometimes but after the next filtering operation and it zooms on the previous filtering extent, not on the current.

Any help about this?

Silverlight 5, c#, featurelayer, zoom to extent, where clause, arcgis Server 10

You set the Map.Extent too early.
The FullExtent of the layer is updated only after the layer itself has been updated.

So it should work by setting the Map.Extent in an Layer.UpdateCompleted handler.
