Zoom to Query Result

[BrianLeroux]

I am trying to zoom to the results of a query which is added to my map as a graphics layer. I have been trying numerous ways to get the map to zoom to that layer but can't get it to work. Once the layer is added I have no issues with using the Go To buton to zoom into the layer. I am missing something but I am not sure what. Here is a sample of one way I was trying to accomplish this.

string layerID = "Policy";
 Layer zoomlayer = MapApplication.Current.Map.Layers[layerID];
 MapApplication.Current.Map.ZoomTo(zoomlayer.FullExtent.Extent);

PanTo works with this but ZoomTo does not. ??

MapApplication.Current.Map.PanTo(zoomlayer.FullExtent.Extent);.

Have you tried something like this:

MapApplication.Current.Map.Extent = zoomLayer.FullExtent;

[BrianLeroux]

Have you tried something like this:

MapApplication.Current.Map.Extent = zoomLayer.FullExtent;

This did not work. Map extent remained the same.

NEVER MIND.  I FOUND IT.

Based on your suggestion, "MapApplication.Current.Map.PanTo(zoomlayer.FullExtent.Extent);", I am unable to see "Current" under MapApplication nor "Map" after "Current", what do I miss?  Thanks

You have pointed to the wrong assembly.
This is the full path to the map:
ESRI.ArcGIS.Client.Extensibility.MapApplication.Current.Map
