Silverlight 2.1 API legend control does not refresh with 10SP1 Services

[SloaneWalker]

I am using silverlight 2.1 API, Visual Studio 2010, ArcGIS 10.0 SP1 and my legend control will not refresh.  The Service can be turned on and off, but not the sub layers.  If I switch over to my 10 Services on my Production Server, it works. Has anyone else had this problem?

Is your service cached?

If cached, it's not possible to change the sublayer visibilities (since the exported images are generated from the cache).

[SloaneWalker]

No, the services are not cached.  There is no difference in the service configuration between the services running with ArcGIS Server 10 and ArcGIS Server 10SP1.  The legend works with the 10 services but not the 10SP1 Services.

Thanks for your help.  I am stumped on this one, I have tried all the obviouse things.

[DominiqueBroux]

I perhaps misunderstood your issue.

Do you mean that you don't get any legend infos (no sublayers, no swatches) for your 10SP1 service?

If it's the case, could you test your legend rest end point?  (something like : http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Median_Age/MapServer/legend)

[SloaneWalker]

No, I get sub layers and swatches, what does not work is the check boxes to turn the layers on and off.

Could you share the result of this kind of request on your service : http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Median_Age/MapServer?f=pjson ?
(or share just the URL if your service is public).

Also check that your REST end point is able to manage sublayer visibilities:
- make a request on your map server (like http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Median_Age/MapServer)
- click ExportMap
- test with various Layers (such as 1 or 2 or 3...) and check that the sublayer visibilities are taken into account

[SloaneWalker]

AAhh, yes, I see that sublayers are null.  Why would htat be and how to creect it?

Thanks!  Here is my URL

http://buster/ArcGIS/rest/services/theMAPex/theMAPexOCP/MapServer?f=pjson

[DominiqueBroux]

I can't access 'buster'. Please share the result of the request.

this is what I get:

Thanks so much for your help.

[DominiqueBroux]

The only thing I noticed is that lot of your layers have relatively low MinScale (24000).

If you are using the legend template of the interactive SDK:

 
 
 <CheckBox Content="{Binding Label}"
                  IsChecked="{Binding IsEnabled, Mode=TwoWay}"
                  IsEnabled="{Binding IsInScaleRange}" >
                            </CheckBox>

you will notice that the checbox is not enabled while the map is not in the scale range of the layer, i.e. in your case, you need to zoom in a lot.

Not sure it's your issue, but it's worth the try to test after removing that 'IsEnabled="{Binding IsInScaleRange}" '
