Hello all, I got this working so here is my review. The help doc that finally hit the mark is this http://resources.arcgis.com/en/help/arcgis-rest-api/index.html#/Accessing_services_provided_by_Esri/02r300000268000000/ The main issues I had were that I was trying to authenticate with the wrong service. Most proxy examples are using this URL to get the token, (and this may still be possible but I didn't have luck with it) https://www.arcgis.com/sharing/genrateToken The example above, for OAuth uses this token generator https://www.arcgis.com/sharing/oauth2/token I also had a harder look at the code within the proxy and realized that it had to be adjusted to accommodate the new URL, basically just adjust the query string that calls for the token (stuff like changing 'username' to 'client_id' to match the url in Step7 of the help doc above) Something else that messed me up when someone tried to explain it to me was the (Step 3) Create New Application. The process just didn't sound logical to me and I was fighting to know how it related to my local app. This 'New Application' has 100% nothing to do with your local application, it is just an ID and secret generator tied to your AGOL account. It should be renamed to 'OAuth Credential Generator' period. I also forgot to mention that I was first trying this with a small html JavaScript project, but these successful steps were with my Silverlight app (which was my final goal anyways) but hopefully this is still relevant to this forum. Here is some code too (I added 'client_id' & 'client_secret' attributes to the 'SeverItem' class) proxy.config <serverItem url="http://route.arcgis.com/arcgis/rest/services" matchAll="true"                client_id="<client_id>" client_secret="<client_secret>" permitted_referer="http://localhost"                tokenUrl="https://www.arcgis.com/sharing/oauth2/token" /> proxy.ashx if (theToken == null)                         {                             string tokenServiceUrl = string.Format("{0}?client_id={1}&client_secret={2}",                                 si.TokenUrl, si.Client_id, si.Client_secret);                             int timeout = 60;                             if (si.Timeout > 0)                                 timeout = si.Timeout;                             tokenServiceUrl += string.Format("&expiration={0}", timeout);                             DateTime endTime = DateTime.Now.AddMinutes(timeout);                             tokenServiceUrl += "&grant_type=client_credentials"; I split the returned token to get just the token string, I'm sure there is a better way to do this but this was the first time dealing with a json response if (string.IsNullOrEmpty(token))             token = generateToken(uri);                 string[] sTokenParts = token.Split('"');         if (!String.IsNullOrEmpty(token))         {             if (uri.Contains("?"))                 uri += "token=" + sTokenParts[3]; //token; take home lesson, never assume all proxy code is plug and play, they must be adjusted for your purpose. ...

Okay, we think we have the problem tackled, here is some code to turn on parent items when a subitem is clicked on. XAML for Legend (Sublayers) <!--Layers within MapLayers--> <esriToolkit:Legend.LayerTemplate>  <DataTemplate>   <CheckBox x:Name="chkLayerItemVis" Content="{Binding Label}"    IsChecked="{Binding IsEnabled, Mode=TwoWay}"    IsEnabled="{Binding IsInScaleRange}"    Click="chkLayerItemVis_Click"    Tag="{Binding SubLayerID}">   </CheckBox>  </DataTemplate> </esriToolkit:Legend.LayerTemplate> c# for chkLaterItemVis_Click and turnOnParents private void chkLayerItemVis_Click(object sender, RoutedEventArgs e)         {             // Goal is to set visibility of parent Layers if child layer is checked.             CheckBox chk = sender as CheckBox;              // Only concerned if they checked the layer 'on'             if (chk.IsChecked == true)             {                 // At this time - we know the 'name' and 'SubLayerID' (bound SubLayerID to chk's 'Tag' in XAML) of the checked layer (child)                 // this will result in all parent layers being turned on, if they have a child with the same name and ID as                 // what was clicked.                 //                 // Because we are using name AND ID (and IDs don't double up), this will only happen if multiple DynamicLayers layers have the same 'name / ID' child combos                 //                 // you can do the same with only 'name', but parents will turn on if they have a child with the same name as what was clicked                 //                 string NameOfLayerChecked = chk.Content.ToString();                 int IDOfLayerChecked = (int)chk.Tag;                  foreach (Layer l in MyMap.Layers)                 {                     // Only concerned about Dynamic Layers - only ones that would be checked.                     if (l is ArcGISDynamicMapServiceLayer)                     {                         ArcGISDynamicMapServiceLayer dl = l as ArcGISDynamicMapServiceLayer;                          foreach (LayerInfo vLayerInfo in dl.Layers)                                                                                      //if (NameOfLayerChecked == vLayerInfo.Name)                             // optional - use name only, see note above                             //                             if (NameOfLayerChecked == vLayerInfo.Name && IDOfLayerChecked == vLayerInfo.ID)                             {                                 // We have found a Layer in the Dynamic Map Service that matches                                 // the name and ID of the layer box checked                                  // Set the root to on                                 dl.Visible = true;                                  // set layerID and pass on                                 int turnedOnLayerID = vLayerInfo.ID;                                 turnOnParents(dl, turnedOnLayerID);                             }                     }                 }             }         }          private void turnOnParents(ArcGISDynamicMapServiceLayer pLayer, int pChildID)         {                         ArcGISDynamicMapServiceLayer dl = pLayer as ArcGISDynamicMapServiceLayer;              int tParentLayerID;             int tID;             foreach (LayerInfo vLayerInfo in dl.Layers)             {                 // Check to see if there are any sublayers                 if (vLayerInfo.SubLayerIds != null)                 {                     // Loop through Sub Layers - and see if any of them have our child                      for (int q = 0; q < vLayerInfo.SubLayerIds.Length; q++)                     {                         tID = vLayerInfo.SubLayerIds ;                         if (tID == pChildID)                         {                             // We found a Parent that has our child                              // set visibility                             tParentLayerID = vLayerInfo.ID;                             dl.SetLayerVisibility(tParentLayerID, true);                              // Check to see if Parent has Grandparrents...                             turnOnParents(pLayer, tParentLayerID);                         }                     }                 }             }          } I hope others find this helpful, it has been working great for us ...
