I'd like to know what settings others use for global turns in a street network dataset.  The default turn costs just seem too low when you consider time required to slow down, make the turn, and speed back up to an average speed, not to mention the possibilities for stop signs and traffic lights.  I am setting this up for fire department apparatus response, but I'm interested in hearing from anyone.  For people who use this global turn delay evaluator, what settings did you use?

How do you populate a DataGrid with the attributes of features in a FeatureLayer?  I've searched high and low and can't find the answer to this question, which is frustrating because it seems so fundamental.  Apparently, you can set the dataProvider property of the DataGrid to the attributes property of a FeatureSet object.  However, I can't get a reference to a FeatureSet object containing all the features in a FeatureLayer.  I've tried using the featureCollection property of the FeatureLayer object, but that is always null.  I've seen ways to do it using queries and selections, but I want to put the attributes of all the features from the FeatureLayer in the DataGrid.

I'm playing with a Silverlight app in Visual Studio so that I can learn programming with the API for Silverlight.  I created a feature layer that points to a fire stations map service on our ArcGIS Server.  I'm following the example in the getting started pages for creating a symbol in the Grid.Resources tag and using it as a static resource for the FeatureSymbol property of the FeatureLayer.  When I comment out the SimpleMarkerSymbol tag in Grid.Resources, it builds fine, but won't run because it can't find the reference to MyMarkerSymbol.  When I include the SimpleMarkerSymbol tag in Grid.Resources, I get a build error.  Below are the error and my code.  Any help would be appreciated.

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
