Hi Mike;

Congrats to you and the team for the RTM;

Could you PLEASE verify and explain the status of the Silverlight "Client" side for Astoria? Is it completed now? Is the INotifyChange implemented for two-way binding?

Where can I get docs for the Async commands and "How to" use them?

Please give us detail on this subject! Thank you in advance!

..Ben

I'd like to second BenHayat's question above. In particular:

- I'm getting an exception now when using the Silverlight client. Forum posting: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=3736840&SiteID=1 .

- Is there documentation or sample code available for the new exception handling architecture using HandleException? I like the sound of the description of it in the article, but I'm not sure what the "error message structure" is, how it is used, or how the error is exposed on the client side (particularly Silverlight).

Thanks,

David

Hi,

Can you pls describe how to delete a object which has a Foreign key? Let me describe the scenario

I have a User with multiple UserProfile so UserProfile has a FK for User. To add a new User profile i write the following code

UserProfile profile = new UserProfile();

profile.UserIdentity = user;

entityStore.AddObject("UserProfile", profile);

profile.UserIdentity.UserProfile.Add(profile);

entityStore.AddLink(profile.UserIdentity, "UserProfile", profile);

entityStore.BeginSaveChanges(SaveChangesOptions.Batch, delegate(IAsyncResult asyncResult)

{ entityStore.EndSaveChanges(asyncResult); }, null);

This works and a new Profile is added.

Now i want to delete this profile.

In beta the following code worked

var profile = entityStore.UserProfile.Expand("UserIdentity").Where(p => p.profileid == profileid);

UserProfile userProfile = profile.First<UserProfile>();

entityStore.DeleteObject(profile.First<UserProfile>());

entityStore.DetachLink(profile, "UserIdentity", profile.First<UserProfile>().UserIdentity);

entityStore.BeginSaveChanges(SaveChangesOptions.Batch, delegate(IAsyncResult asyncResult)

{ entityStore.EndSaveChanges(asyncResult); }, null);

But this doesn't work now. I've tried with DeleteLink and also with

entityStore.DetachLink(userProfile.UserIdentity, "UserProfile", userProfile) but no luck ...all i get is "There was an error processing this request..

I culd not find a sample in th RTM traning kit for this scenaro either. Please help here..

Thanks

Paging support (i.e., TotalCount). Without it, you're completely in the dark as to how bad a query is (e.g., "page 1 of 1234567"), what to expect ("1 [2] 3 4" v.s. "where am I?"), or to make a reasonable guess how far you must skip ("page 1 of 8; I need something beginning with an S... let's try page 6" vs. "Next, Next, Next, Next, Next, Next, *curse*, Previous"). It's my pet peeve to skip v1.

Something like http://myserver/data.svc/Customers(’ALFKI’)/Orders/$count?$filter=...

Support for aggregates in general would be cute, but not that important. Aggregate calculations are ideally suited for business methods on a service, because when you start, you'll have to add group by and subqueries and ... And before you know it you've built SqlToUrlToLinqToSql.

Where is the main Astoria discussion happening. forum/newsgroup something else? Best place to ask questions please. Preferably frequented by some MS Staff/MVPs who are in the know

re: RTM is here!

pabloc — Tue, 19 Aug 2008 05:58:49 GMT

Ruben: for paging, for this release you can use next/pev instead of page number. Total count and page numbers are tricky to compute without triggering an expensive operation on the database, so we want to be careful on how we introduce support for this. Regarding aggregates...yes, we got several requests for it, we'll look at it eventually but there is a bunch of other stuff that we're getting ask for as well.

Nick Williams — Sun, 14 Sep 2008 13:50:08 GMT

I'm also distraught about the lack of efficient results count. My main ajax control (a grid) utilizes on-demand data fetching as the grid is scrolled. I need an accurate count to be able to allow skipping through records by dragging the scroll bar and indicating which records are visible as a range - along with using the count value with the scroll bars themselves to size the grab region.

Retrieving the count of records in an efficient manner is an absolute necessity for modern AJAX.

re: RTM is here!

pabloc — Mon, 15 Sep 2008 21:40:20 GMT

Hi Nick,

Yes, I agree that not having count is painful. Hopefully we'll be able to address that soon.

That said, I've seen various AJAX clients that do without it for various reasons. For example, the Yahoo mail interface dynamically adjusts the scrollbar and content in general as you scroll down and they find more about the items available.

As a bit of background: for the cases where data is in a relational database, in general obtaining the row count is a quite expensive operation (often it involves counting rows in the most compact index/heap available). There are shortcuts sometimes, but they introduce a non-uniform way of finding out the count.

Also, naturally, the count is pretty much always innacurate. The moment the value left the server, it may already have chanced undernead; also, page counts can change from page to page. So for various reasons certain level of innacuracy needs to be tolerated by the app.

re: RTM is here!

Nick Williams — Fri, 19 Sep 2008 00:51:40 GMT

Perhaps I've put too much emphasis on the accuracy side of things. You can see what I'm attempting to do here: http://www.siteartwork.de/livegrid_demo/

If it's off by 2 out of 1,000 due to new inserts - no big deal. But I do need to know whether there's 100 or 5,000 results. If it takes 2 seconds of extra processing to determine that there's 5000 results - that's no big deal as I'm not going to ever have to get that count again for the view. This same requirement applies to many other things I will need to do with my project - letting the user know they're on page 1 of 20 in a particular category, that their search for some broad term has returned an enormous amount of results and that they should refine things futher, etc.

From what I've been reading lately, I'm not sure that it's even possible to count the entities returned server side while using a filter or other logic via the URI. Is there *any* way to determine the number of results being returned through a URI such as

/Orders?$filter=ShipCountry eq 'France'

that can be self-contained in the data layer (ie. no counting rows client side)? The answer to that question is the maker/breaker.

I appreciate you taking your time to reply.

re: RTM is here!

pabloc — Fri, 19 Sep 2008 21:22:48 GMT

Hi Nick,

For the case where you're using a database as a backend (e.g. it's not your LINQ implementation), which is the most common case, I don't think there is a way of doing this short of looking at the filter expression yourself, which I would strongly encourage not to.

I checked out the grid sample and the grid looks really, really nice. Impressive job.

For something like a data service, you'd have to dynamically fix up the scrollbar as you find out that more rows are available, or introduce a next/prev kind of UI (which I understand that doesn't fit well in the grid as it is today).

I'll keep this in the back of my mind. If I come up with some approach to do this I'll post it somewhere.

-pablo

re: RTM is here!

Nick Williams — Fri, 19 Sep 2008 23:30:19 GMT

I am truly flabbergasted that there is no way to determine the number of results returned. Data Services seems kind of pointless to me, if this simple requirement can't be fulfilled.

re: RTM is here!

Nick Williams — Fri, 19 Sep 2008 23:39:21 GMT

If we DID provide a next/previous page we wouldn't even know when to disable the "NEXT" button unless the client-side count happened to be less than our $top value! This is so silly! Why even provide paging if you can't tell what page you're on!? Why waste your time offering paging functions if you didn't plan to let us know when we're on the last page? This is so absolutely silly. Data Services paging belongs on the from page of The Daily WTF - really.

I have to agree with Nick. Data Services without paging is silly. The product is not feature complete until this is added.

pabloc — Wed, 18 Feb 2009 03:15:42 GMT

@Robert: we heard that loud and clear from all of you guys, so we're working to add that feature for the next release. We should have the feature built into the first public beta/ctp/whatever release that we ship.

Standard disclaimer applies: there is never a guarantee about features for unreleased products until they hit RTM.

re: RTM is here!

Robert Claypool — Thu, 19 Feb 2009 23:26:17 GMT

Thanks Pablo, good to hear --

For now, I'm using a WebGet method to retrieve the count and I've learned that field names in the string predicate must specify the "it" namespace ... such as "it.Category == \"Overstock\""

Can you explain this? I can't find any documentation on "it"

[WebGet]

[SingleResult]

public int CountOrders(string prediate)

{

// Note: field names in the prediate must be prefixed with "it."

return CurrentDataSource.Orders.Where(prediate).Count();

}

Thanks again!
