Your Layers binding needs to have Mode=TwoWay added to the Binding statement is one thing I notice.  Also your ViewModel is your DataContext so I do not think you want the Binding to have ViewModel in there.  I think this would do it     Layers="{Binding BaseMapLayerService, Mode=TwoWay} Hope that helps -Joe ...

Assuming you are always having the button content be the name of the state you can avoid a long if block with;         private void RadioButton_Click(object sender, RoutedEventArgs e)         {             // Query task initialization.             QueryTask queryTask = new QueryTask("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/" +               "Demographics/ESRI_Census_USA/MapServer/5");             queryTask.ExecuteCompleted += QueryTask_ExecuteCompleted;             queryTask.Failed += QueryTask_Failed;               // Query task parameters. Return geometry, state, and population density.             Query query = new Query();             query.ReturnGeometry = true;             query.OutFields.AddRange(new string[] { "STATE_NAME"});                          //The Clicked Radio button is always the one selected..             RadioButton button = sender as RadioButton;             if ( button == null ) return;               query.Where = "STATE_NAME = '" + button.Content + "'";               queryTask.ExecuteAsync(query);         } ...

The visible columns is tied to the OutFields collection so the easiest way is to just set the OutFields to only the ones you want.  But it seems you want attributes available for the map tip that do not show up. While I have not done it FeatureDataGrid inherits from DataGrid so I assume you can set the Columns like you have started to below.  In order to do this you need to first set the AutoGererateColumns  property on the FeatureDataGrid to false.  Then in your Columns definition only put the ones you do want to see\ Hope that helps -Joe ...
