Silverlight legend doesn't read grouped values

AdamFeidt — Wed, 16 Nov 2011 15:06:43 GMT

In my published service, which is using an msd, I have multiple symbol values grouped into one label. Inside my Silverlight legend the values display individually. I understand what's happening here because my Rest Services page is rendering on a unique VALUE and shows them each individually, but is there any way to correct this or work around this?

The workaround may be to remove the duplicate legend items (based on the Label)

You can hook up an handler to the Legend refreshed event :

 
private void Legend_Refreshed(object sender, ESRI.ArcGIS.Client.Toolkit.Legend.RefreshedEventArgs e)
{
    var items = e.LayerItem.LegendItems;
    if (e.LayerItem.Layer is FeatureLayer && items != null)
    {
        // Group the items by Label and keep only the first one
        var toRemove = items.GroupBy(item => item.Label).SelectMany(g => g.Skip(1)).ToArray();
        foreach (var item in toRemove)
            items.Remove(item);
    }
}
