Capture Synchronization Event

Question

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,

E

Excellent, thank you. I actually did something similar private void btnGetData_Click(object sender, EventArgs e) { Cursor.Current = Cursors.WaitCursor; QueryFilter qf = MakeCacheQuery(); IEnumerable 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 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); } }

Sorry about the delayed response, so busy with work.

Here is the code to perform sync. There are 2 variations, this one gives more control per layer.
mobileCache = new MobileCache("put your path here the folder that contains the cache");

MobileServiceConnection con = new MobileServiceConnection(); 
con.Url = (@http:// + ServerType._StaticArcGISServerName + "/arcgis/services/Mobile_Services/" + AppSettings._StaticSynchronizationName + "/MapServer/Mobileserver");
con.CreateCache(mobileCache.StoragePath); 
mobileCache.Open();
                                        
foreach (Layer layer in mobileCache.Layers)
{
FeatureLayer featureLayer = (FeatureLayer)layer;
FeatureLayerSyncAgent layerSyncAgent = new FeatureLayerSyncAgent(featureLayer);
layerSyncAgent.MapDocumentConnection = con;
layerSyncAgent.SynchronizationDirection = SyncDirection.UploadOnly;
SyncResults theSyncResults = new SyncResults();
theSyncResults = layerSyncAgent.Synchronize();                                                
}

So, it turns out that there is no event to capture and the sync tools cannot really be customized.

The solution to this problem was a complete re-write of the sync functions for both posting and getting data
