How to know the progress of the Sync when I call PullAsync()

Question

Hi,
I am developing a Windows 8.1 app, In that I am using offline data concept using Azure mobile services with JavaScript Backend.
My questions is how can I show the status or progress of the Sync When I call PullAsync() method.... I want to show the number of records sync or how much percentage synced like that...
private async void ButtonPull_Click(object sender, Windows.UI.Xaml.RoutedEventArgs e)
await todoTable.PullAsync();
//How to know the progress of sync
await RefreshTodoItems();

Hi Narendra,
I suggest you to check this information for more details.
PullAsync() call can either pull all items from the remote table, or just pull a subset of the items. Only pulling some items from the table is often advisable, as stuffing everything from the (potentially large) remote database table into the (restricted by
the device memory) local table may have some bad performance implications. You can pass an OData-formatted query to select which items to pull from the server, or you can also use the (more friendly) Linq expressions to determine the query of items to be pulled.
var localTable = client.GetSyncTable<TodoItem>();
var query = localTable.Where(t => !t.Complete);
await localTable.PullAsync(query);
var localItems =
await localTable
    .Select(i => i.Text)
    .ToListAsync();
AddToDebug("Items from the server (in the local table): {0}",
string.Join(", ",
localItems));
One important thing to notice regarding pull operations – if there are items in the pending synchronization queue, those items are first pushed over to the server, then the pull operation takes place. That prevents a scenario where an update is done to a
local item, but a pull operation would overwrite the changes locally and potentially leave the data in an inconsistent state. That’s one the first synchronization rule: a pull triggers a push. In the example below, the insert operation for the “Buy milk” item
will first be pushed to the server, then the items will be pulled into the local table.
await client.SyncContext.InitializeAsync(store);
AddToDebug("Initialized the sync context");
var localTable = client.GetSyncTable<TodoItem>();
var item =
newTodoItem { Text =
"Buy milk", Complete =
false };
await localTable.InsertAsync(item);
var query = localTable.Where(t => !t.Complete);
await localTable.PullAsync(query);
var localItems =
await localTable
    .Select(i => i.Text)
    .ToListAsync();
AddToDebug("Items from the server (in the local table): {0}",
string.Join(", ",
localItems));
for us to better understand both Push() and pullasync() feature is used while querying from the Database.
