Updating data in a Table

JoeHershman

I have followed the path outlined in the thread on editing records http://forums.arcgis.com/threads/21714-Editing-Tables-in-Feature-Service-with-Silverlight-4 and while that works for adding new records it does not address editing of existing rows in a table which I have found quite difficult partially because of what I would consider a bug with the API.

When I create a FeatureLayer object in code like shown in the thread on adding records and call initialize on the FeatureLayer, when the Initialized is returned the Graphics collection is empty even though there are objects in my table.  I have played around with different approaches when creating the FeatureLayer, giving OIDs putting a Where clause of ???OBJECTID >  0,??? but in all cases the Graphics collection is empty and never populates.  What I have also tried is to add the FeatureLayer to the map in code still no luck. 

However, when the FeatureLayer is added to the map in Xaml it does have a populated Graphics collection.  Why is there is different behavior when adding through Xaml compared to adding in code?  I would consider that a bug.
Once my Graphics collection is populated I am able to update a record by finding the proper Graphic object and changing the attributes and calling Save.  Something along the lines of;

    Graphic graphic = _featureLayer.Graphics.Where(g => (int)g.Attributes[OBJECTID] == ObjectId).FirstOrDefault();      graphic[NAME] = newValue;      _feaureLayer.Save();

Adding the FeatureLayer in Xaml is not really an option in how my application is designed (well it is an option, one that defeats the entire point in having architected a modular MVVM application).  To me something is wrong, you should not have to add a FeatureLayer in Xaml to make something work, creating the object in code and calling initialize should have the same behavior.  Could someone look into this, perhaps I am missing something.

So went back to this to see if I could track down the problem.  Set up everything the same as it had been, and it is working update fine Graphics are loaded.  I looked back in subversion and I swear it is the same code that was failing.  I am going to blame it on solar flares or something of that nature.  All I know is it is working so I will just be happy about that and move forward.

Thanks
