I want to add some authentication to my odata service. Depending on the user calling i want to: filter rows and/or remove columns. I read in scott hanselmans fine blogpost on odata ( http://www.hanselman.com/blog/CreatingAnODataAPIForStackOverflowIncludingXMLAndJSONIn30Minutes.aspx )that it is possible to intercept the incoming queries...

Is there a blogpost or example on how to combine the ext-js grid with an odata datasource? I suspect it would require a custom datareader. ...
I would like to add some tags to our web app to enable auto-discovery of our odata feeds. So for example Nerd Dinner has the following tag: <link rel="odata.service" title="NerdDinner.com OData Service" href="/Services/OData.svc" /><link rel="odata.feed" title="NerdDinner.com OData Service - Dinners" href="/Services/OData.svc/Dinners...
I have a project that needs to implement WCF data services (OData) to retrieve data from a control system (.NET Framework Application). The WCF data service needs to be hosted by the .NET application (No ASP.NET and NO IIS). I have seen many WCF Data Service examples recently; they are all hosted by ASP.NET application. I also see the s...
Hi, I'm looking for the simplest way to implement row-level authorization in Entity Framework 4. Something like odata's query / change interceptors would be great. This two-year-old msdn forum thread mentions that it was on the team's to-do list at that time. Has this been implemented by now? I could not find anything anything related...
Hi there, can anyone help? I recently had asp.net membership setup using a connection string to my db via the web.config in my service layer. It enabled me to do something like this :- public bool IsValidLogin(string username, string password) { return System.Web.Security.Membership.ValidateUser(username, password); ...
I've got a data model that has two tables with a join table for a many to many relationship & creating an OData service to expose the data for CRUD ops in a Silverlight app. What I'd like to do is abstract the join table from the service. I'm not sure if the best way to do this would be in the model (using EF in .NET3.5SP1) or if I shoul...
From my personal research, it appears that OData implementations depend extensively on MS Entity framework. It would seem possible to implement the OData producer protocol using an open ORM like NHibernate in C# or Hibernate in Java. In the best of all worlds, it would be cool to expose data using OData protocol from Oracle. I am ope...
Hi, I need to host a WCF Data service as part of a legacy ASP.NET MVC website running in IIS 7 Integrated mode. Read access to the web service is working fine, but whenever I try to POST to the web service, I get a 400 Bad Request error. For testing purposes, I have downloaded the sample odata service from http://www.odata.org/develop...
I successfully ran the following statement with the NorthWind.sdf in LinqPad: from s in Shippers select new { s.ShipperID, s.CompanyName, Count=s.ShipViaOrders.Count() } At the same time , I failed to run a similar statement with the Odata Service (http://services.odata.org/northwind/northwind.svc) in Linq...

I'm fairly new to WCF DataServices (OData) and I need to know the best way to instantiate the entity container on the client without hard-coding the URI. It seems like all of the examples on MSDN describe instantiating the client like this: Uri uri = new Uri("http://www.someservice.svc"); DataServiceContext svc = new DataServiceContext(...
I have a table in a database which is a store of Key/Value pairs, with some type information on the type of data stored in the value field. I've read the blog series on creating an untyped data provider, and have grabbed and messed with the samples from odata, but I can not figure out how to turn the sample which uses an in-memory Dic...
I've created a new Silverlight application, so I have a web project called "SilverlightOnLineChess.Web" and the Silverlight app called "SilverlightOnlineChess.Client". In this solution I've created a new WCF RIA Services class library called "SilverlightOnlineChess.Data", and in doing so it creates the associated web project called "Silv...
As some background I prefer the flexibility and benefits that ASP.NET MVC gives me, and have been building in MVC since its release. But the new project I am about to start requires a complex calendar / scheduler control - and none of the jQuery alternatives meet all the requirements. This has led me to the Telerik Radtools Scheduler, w...
Hello, Can anybody tell me how to customize the OData feed for Ado.Net Data Services using Entity Framework (Code First/Only)? There is no EDMX file (as it is Code Only). I have tried adding the attribute: [EntityPropertyMapping( "Id" , SyndicationItemProperty.Title , SyndicationTextContentKind.Plaintext , true )] To my POCO entity...
Is there any metadata versioning support in OData protocol and its WCF Data Services implementation? Let us suppose that we have OData service that exposes the single Goods colletion, and the Goods entity type has three properties: Key (string), Name (string) and AvailableSince(string). The service is already running, and there are some...
Hi! Me and some buddy of mine are trying to get started with WCF Data Services, so let me first describe what we have done so far: We have created a fairly simple WCF Data Service with a data source that implements the IUpdatable interface and exposes some data through some public IQueryable<> attributes (the code is attached at the b...
I tried to create a OData web service using VS 2008 without any luck. I downloaded ODataDemo from Odata.org, installed Microsoft .NET Framework 3.5 Service Pack 1, and ADO.NET Data Services Update for .NET Framework 3.5 for Windows XP. However, I don't see any reference to ADO.NET Data Services Framework. When I tried to add a new ADO.Ne...
