Keeping layer checkbox in sync with layer visibility - SL3 to SL4 issue

MatthewCarey

I have an application that reuses the code from ESRI's 'SubLayer List' sample to populate a listbox with checkboxes to turn each sublayer of the map service on and off (also known as a TOC).

After certain events I turn on a sublayer programmatically. In the Silverlight 3 version of my app I used a method called UpdateLayerList (which I believe was part of an earlier ESRI sample) that would repopulate the listbox and made sure that the checkboxes reflected the visible/not visible status of the sublayers.

In translating the app to Silverlight 4 and looking at the latest sample, the UpdateLayerList method apparently became unnecessary, and now if I try to make use of it the list box becomes blank.

I can still turn on a sublayer programmatically with no issues, but cannot figure out a way to either refresh the TOC with the checkboxes reflecting the sublayers' actual visibility, or at least say specifically "turn on this checkbox for this layer."

I believe the binding process may be part of the answer or there's something else that I'm missing, so any help would be greatly appreciated! Thanks.

To use with multiple map services, you can subscribe to the same ArcGISDynamicMapServiceLayer_Initialized event in Post#2. And modify it so that you can exclude sublayers that contains 'label' in their name.

foreach (LayerInfo l in dynamicServiceLayer.Layers)
{
 if(!l.Name.Contains("label)")
  MySubLayers.Add(new MyLayerInfo(l));
}
