Zoom To Layer

[BrianGustafson]

I am adding a layer programatically and I am trying to zoom to that layer.  However the service that I am adding is in a different spatial reference than my map.  Is there still a way to zoom to that layer when it is added to the map?

[BrianGustafson]

Will the ZoomToLayerAction do this?  How does that work if I want to implement this in the code behind.

Even if spatial reference of the later service is different, it would be re projected on the fly to the spatial reference of the map.So,there should not be any issue.

[BrianGustafson]

The data draws correctly because it does reproject on the fly.  The issue is using that layers geometry to zoom to it when it is loaded into the map.

[SanajyJadhav]

Just for the clarification.

You want to zoom to the extent of the service that is being added later on, right? If yes, are you using Layer::FullExtent property?

[BrianGustafson]

Correct, but that service is in a different projection than the map so it throws an error.  Is there away around that?

[SanajyJadhav]

One thing could be tried out.

1. Create new envelope.
2. Use xMin,xMax,yMin and yMax of the LaterService::FullExtent to set the coordinates of this envelope.
3. Use spatial referene of the map to set Envelope::SpatialReference
4. Set extent.

Let me know if this helps.

What type of layer are you trying to add programmatically? Did you call map.ZoomTo(layer.FullExtent)?

[BrianGustafson]

It is a DynamicMapServiceLayer map service layer that is a different spatial reference than the map.  I am trying to zoom to the layer in the map inside of the initialized event of the loaded layer.
