Relationships On a Tiled Layer In Silverlight API

JamesStreet1 — Fri, 14 Jan 2011 17:57:46 GMT

I know you can access the relationships from a feature layer via myLayer.LayerInfo.Relationships but is there a way to perform something similar for tiled and dynamic layers?

Seems like all the information is there but the LayerInfo class is missing the property.

The FeatureLayerInfo class is giving this info, so what you can do is to create a FeatureLayer by code (even without adding it the map, and get the needed info when the layer is initialized).

Example of code:

private void ArcGISDynamicMapServiceLayer_Initialized(object sender, System.EventArgs e)
{
    ArcGISDynamicMapServiceLayer dynamicLayer = sender as ArcGISDynamicMapServiceLayer;
    if (dynamicLayer != null)
    {
        FeatureLayer featureLayer = new FeatureLayer {Url = dynamicLayer.Url + "/0"};
        featureLayer.Initialized += featureLayer_Initialized;
        featureLayer.Initialize();
    }
}
 
void featureLayer_Initialized(object sender, System.EventArgs e)
{
    var featureLayer = sender as FeatureLayer;
 
    if (featureLayer != null && featureLayer.LayerInfo.Relationships != null)
    {
        foreach (var relationShip in featureLayer.LayerInfo.Relationships)
            Debug.WriteLine(string.Format("RelationShip ID={0} Name={1} RelatedTableId={2}", relationShip.Id, relationShip.Name,
                                            relationShip.RelatedTableId));
    }
}

Used with this map service (http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/MapServer), the result is :
RelationShip ID=1 Name=ServiceRequest_IncidentPriority RelatedTableId=1
