Capture Synchronization Event

KierenTinning1

Does anyone know how to capture, or if it is possible to capture a synchronization event?

For all of my modified features I'd like to know when ArcGIS Mobile starts to synchronize so I can write a value to that group.

Thanks,

Excellent, thank you. I actually did something similar

private void btnGetData_Click(object sender, EventArgs e)
        {
            Cursor.Current = Cursors.WaitCursor;
            QueryFilter qf = MakeCacheQuery();
            IEnumerable<MobileCacheInfo> emi = MobileApplication.Current.Project.EnumerateMobileCacheInfos();

            foreach (MobileCacheInfo mi in emi)
            {
                MobileCache mc = new MobileCache(mi.MobileCache.StoragePath);
               

                if (mc.CacheExists && mc.IsOpen)
                    mc.Close();

                try
                {
                    var con = new MobileServiceConnection();
                    con.Url = mi.MobileServiceConnection.Url;
                    con.CreateCache(mc);
                    mc.Open();
                    ICollection<FeatureLayer> flayers = mc.FeatureLayers;
                    foreach (FeatureLayer fl in flayers)
                    {
                        var flsyncAgent = new FeatureLayerSyncAgent(fl, con);
                        flsyncAgent.SynchronizationDirection = SyncDirection.DownloadOnly;
                        flsyncAgent.DownloadFilter = qf;
                        SyncResults sr = flsyncAgent.Synchronize();
                    }
                }
                finally
                {
                    if (mc != null && mc.CacheExists && mc.IsOpen)
                        mc.Close();
                }

            }
            Cursor.Current = Cursors.Default;
        }

What is really unfortunate here though is the QueryFilter won't accept the GeometricRelationship - I can download all of the data that I have, but not a subset based on the intersection of the layers

private QueryFilter MakeCacheQuery()
        {
            if (cmbDownloadParameter.SelectedIndex < 3)
            {
                GpsConnection gps = Common.Utilities.GPSTools.GpsConnection;
                if (gps == null)
                {
                    gps = MobileApplication.Current.GpsConnectionManager.Connection;
                }

                Coordinate c = MobileApplication.Current.Project.SpatialReference.FromWgs84(gps.Longitude, gps.Latitude);
                Geometry pointGeom = new ESRI.ArcGIS.Mobile.Geometries.Point(c);

                Double dblRad = 100;

                if (cmbDownloadParameter.SelectedItem.ToString().Equals("100 Meters"))
                    dblRad = 100;
                else if (cmbDownloadParameter.SelectedItem.ToString().Equals("500 Meters"))
                    dblRad = 500;
                else if (cmbDownloadParameter.SelectedItem.ToString().Equals("1 Kilometer"))
                    dblRad = 1000;



                Polygon pg = Common.Geography.Geometry.BufferPointFromGpsCoordinate(c, dblRad);
                QueryFilter qf = new QueryFilter(pg, GeometricRelationshipType.Intersect);
                return qf;

            }
}

With the buffering code here

public static class Geometry
    {
        public static Polygon BufferPointFromGpsCoordinate(Coordinate c, Double dblRadius)
        {
            Double dbDegreeToMeter = 0.0000089928;
            Int32 degreeInterval = 1;

            CoordinateCollection coordCollection = new CoordinateCollection();

            for (Double degree = 0; degree < 360; degree += degreeInterval)
            {
                Coordinate radiusCoordinate = new Coordinate();
                radiusCoordinate.X = c.X + (Math.Cos((degree / 360) * 2 * Math.PI) * dbDegreeToMeter * dblRadius);
                radiusCoordinate.Y = c.Y + (Math.Cos((degree / 360) * 2 * Math.PI) * dbDegreeToMeter * dblRadius);

                coordCollection.Add(radiusCoordinate);
            }
           
            return new Polygon(coordCollection);
        }

    }
