I cant Sync SQL Server on Windows Phone 7, Here's my code. Please help!! RRS feed

  • Question

  • Hi,


    I'm using the Microsoft Sync Framework 4.0 and have generated the service from the SvcUtilHelper and added it to the server. Here's the code




    public class UserSyncSyncService : Microsoft.Synchronization.Services.SyncService<UserSyncOfflineEntities> {
            public static void InitializeService(Microsoft.Synchronization.Services.ISyncServiceConfiguration config) {
                // TODO: MUST set these values
                 config.ServerConnectionString = @NutriLeaf.Services.Constants.Settings.ServerDbConnectionString;
                // TODO: Optional.
                config.EnableDiagnosticPage = true;
                config.UseVerboseErrors = true;
                config.AddFilterParameterConfiguration("UserID", "Users", "@UserID", typeof(int));
                config.AddFilterParameterConfiguration("UserID", "UserProfiles", "@UserProfileID", typeof(int));



    and have also included the cross domain acccess xml file. Viewed the diagnostic page with all test PASSED!


    Client :


    Here's the code on my phone 7 : Generated the DataContext from the Utility again!

     public static void SyncUser()
                if (setting.User.UserID == 0 || setting.User.UserID == null)
                context.CacheController.ControllerBehavior.AddScopeParameters("UserID", setting.User.UserID.ToString());
                context.CacheController.ControllerBehavior.SerializationFormat = Microsoft.Synchronization.ClientServices.SerializationFormat.ODataJSON;
                context.LoadCompleted += new EventHandler<Microsoft.Synchronization.ClientServices.IsolatedStorage.LoadCompletedEventArgs>(context_LoadCompleted);
            static void context_LoadCompleted(object sender, Microsoft.Synchronization.ClientServices.IsolatedStorage.LoadCompletedEventArgs e)
                context.UsersCollection.Single(); //ERROR - Sequence contains no elements
                EventHandler completed = UserSyncCompleted;
                if (completed != null)
                    completed(UserSyncCompleted, EventArgs.Empty);


    I know, I have a single element on the server. Why cant I get that down to my client??


    Please Help!!

  • does this happen on first sync? or subsequent sync?

    try running SQL Profiler and see what select query it's firing and see if it's actually returning rows.
