I have followed the Open Access dsw tutorial (http://www.telerik.com/help/openaccess-orm/getting-started-root-quickstart-wpf-overview.html) so that I have generated only a single .generated.cs from one view on my SQL server.
How do I link this to the RadGridView? I have tried following your tutorials, however, a severe lack of skills on my part, has proven this to be a difficult task to carry out. If would also be great if I could display the filters for each heading as well.
Cheers. Any help is appreciated.
Regards, Al.

I'm really stuck with this one. Do you have an example I could download?
Thanks again.
Al
I am sending you a sample project based on the same tutorial that you mentioned.
I hope that helps.

Thanks for posting the example. When Building I get a couple of errors. Are you able to help out with these?Cheers. Al

I have managed to put together a simple project solution with no build errors. When published I do not get any data rows on the gridview. Are you able to help? At least I will have a template to build on then. I am just rushing to get a demo ready for a client.
Would I be able to post the solution file I have? Thanks. Al.
May you check the App.Config file and more specifically the conntectionStings section?
<
add
name
=
"NorthwindConnection"
connectionString
=
"data source=.\SQLExpress;initial catalog=Northwind;integrated security=True"
providerName
=
"System.Data.SqlClient"
/>
The data source should correspond to the name of your server - in my case it is SQLExpress.

I have gone completely back to the start of the tutorial, (http://www.telerik.com/help/openaccess-orm/getting-started-root-quickstart-wpf-overview.html).
Builds and Publishes OK, however, when I click the 'LoadCars' button in the Window I get an error: (I have added a reference to both projects for Telerik.OpenAccess.Config, but this doesn't stop from the error from appearing) - thanks again for your help. Al.

It seems that for some reason we are not able to correctly resolve the Telerik.OpenAccess.Config assembly. Can you please share with us with what are you working? Are you working with an installed version of OpenAccess or you are just referencing the required assemblies from a local folder?
Also can you please confirm that the project is successfully build after you add the references to Telerik.OpenAccess.Config?

Build is successful. I have an installed version of Open Access 2011.1.411. When I referenced the .config file I did so from Add Reference --> .NET -->Telerik.OpenAccess.Config Version 1.0.0.0, Runtime version v2.0.50727. I hope this helps.
I am happy to send through the VS file if you require it.

I tried reproducing your issue numerous times but unfortunately I cannot do so. Is it possible for you to send us your project (or a sample subset of it that shows the problem so that we can debug it here locally. If it is possible for you then please let us know and I will convert this thread to one that allows attachments (and is private).
If not can you please look into the following possibilities:
1. You have a mismatch in the versions of one or more OpenAccess assemblies.
2. You have put reference to the Config assembly in a project other than the one responsible for the database communication.

I developed a simple app and came across the same problem. Added .config file and it worked... I was happy to say the least :)
Any, back to this project, I noticed that I did not have the option on which increments the Build version between publishes on the Project Properties 'Publish'. It was always overwriting 1.0.0.1. Anyway, I set it to on, VS published 1.0.0.2, everything loaded ok, clicked Load Cars and the Gridview displayed the results... I've learnt now to make sure 'Automatically increment revision with each publish' should be ticked!
Thank you so much for your support. This is what makes Telerik, in my opinion, stand out from the crowd. Keep up the great work.

We are happy that you have managed to resolve your problem. Please feel free to contact us back in case you encounter any future problems.
