Can you "Get Data" for only select fields?

Question

We are beginning to test the idea of capturing photos using ArcGIS Mobile / use of the Raster field for an upcoming inspection program.

Is there any way to restrict the fields (in code or otherwise) that are retrieved when users "Get Data" for an ArcGIS Mobile application?  Specifically, we want the user to post their updates which will include photos stored in the raster field, but when they "Get Data" we don't necessarily want then to download all the photos that have been captured.  We do however want the users to have the latest most complete inventory of assets (streetlights).

We plan on using ArcGIS Mobile build 2525 or most recent on Trimble Juno SC's with integrated camera.

Thanks

Has anyone else got this working properly? I tried doing what fandre did, however, it errors when I try to create the new cache and gives the the error message of "" which isn't much help...

I also noticed that ESRI says to use the following connection string format for the MobileServiceConnection:
mobileServiceConnection1.Url = @"http://YOURSERVER/arcgis/services/YOURSERVICE/MapServer/MobileServer"; 
http://help.arcgis.com/en/arcgismobile/10.0/apis/arcgismobile/api/ESRI.ArcGIS.Mobile~ESRI.ArcGIS.Mobile.Map.html

Should it really be MapServer/MobileServer at the end or just MobileServer?

Here is the code I'm trying to use:
           // Create an instance of MobileCache, and set StoragePath 
            MobileCache mc = new MobileCache(@C:\ArcGIS_Mobile\Projects\MyProject\MobileCache);
            MobileServiceConnection msc = new MobileServiceConnection();
            msc.Url = @"http://MYSERVER/ArcGIS/rest/services/MYSERVICE/MobileServer";
            try
            {
                mc.DeleteCache();
                MobileCacheSyncAgent mobilesync = new MobileCacheSyncAgent(mc, msc);
                MobileCacheSyncResults mobileResults = new MobileCacheSyncResults();
                msc.CreateCache(mc);
                mc.Open();

FeatureLayerSyncResults featLayerResults = new FeatureLayerSyncResults();

FeatureLayerSyncAgent flsa1 = mobilesync.SyncAgents[0] as FeatureLayerSyncAgent;
                flsa1.SynchronizationDirection = SyncDirection.DownloadOnly;
                flsa1.DownloadFilter = new QueryFilter("CaseID = " + txtSearchValue.Text.Trim());
                featLayerResults = flsa1.Synchronize() as FeatureLayerSyncResults;
                mobilesync.Synchronize();
                MobileCacheSyncAgent agent = new MobileCacheSyncAgent(mc);
                agent.MapDocumentConnection = msc;
                agent.DownloadExtent(mc.GetExtent(), 0, 0);
                // Load layers from MobileCache to Map control 
                ViewMapPage mapPage = UtilityFunctions.GetMapPage() as ViewMapPage;
                mapPage.MapControl.Map.MapLayers.AddRange(mc);
                mc.Close();

This errors when I CreateCache. If I don't delete and create a new cache it seems to work although no data is loaded from the server...

Thanks,

Chad

Works 😄 !!!
mobileCache1.DeleteCache();
MobileCacheSyncAgent mobilesync = new MobileCacheSyncAgent(mobileCache1, mobileServiceConnection1);
MobileCacheSyncResults mobileResults = new MobileCacheSyncResults();
mobileServiceConnection1.CreateCache(mobileCache1);
mobileCache1.Open();

try
{
                FeatureLayerSyncResults featLayerResults = new FeatureLayerSyncResults();

//layer de parcelas
                FeatureLayerSyncAgent flsa1 = mobilesync.SyncAgents[0] as FeatureLayerSyncAgent;//new FeatureLayerSyncAgent(fl1,mobileServiceConnection1);
                flsa1.SynchronizationDirection = SyncDirection.DownloadOnly;
                flsa1.DownloadFilter = new QueryFilter("(cd_uso_solo in (140161,139115,139134))");
                featLayerResults = flsa1.Synchronize() as FeatureLayerSyncResults;
                //featLayerResults.FeaturesAddedInCache.Count;

//layer uso solo
                FeatureLayerSyncAgent flsa2 = mobilesync.SyncAgents[1] as FeatureLayerSyncAgent;//new FeatureLayerSyncAgent(fl2, mobileServiceConnection1);
                flsa2.SynchronizationDirection = SyncDirection.DownloadOnly;
                flsa2.DownloadFilter = new QueryFilter("(cd_parcela in (572862,572861,549839))");
                featLayerResults = flsa2.Synchronize() as FeatureLayerSyncResults;
                //featLayerResults.FeaturesAddedInCache.Count;
}
catch (Exception ex)
{
                MessageBox.Show("Cannot synchronize with this service :" + ex.Message);
}
