Hi Brad,

Excellent video for beginners to RIA service. I tried to deploy this demo on IIS ,but error messages always occur when I submit changes. The error detail is :

at System.Windows.Ria.OperationBase.InvokeCompleteAction()

at System.Windows.Ria.OperationBase.Complete(Exception error)

at System.Windows.Ria.SubmitOperation.Complete(OperationErrorStatus errorStatus)

at System.Windows.Ria.DomainContext.<>c__DisplayClassb.<SubmitChanges>b__3(Object )

Caused by: And error occurred while submitting changes on the DomainContext of type 'DishViewDomainContext' and the error was not handled. You must handle the SubmittedChanges event on the DomainDataSource and call SubmittedChangesEventArgs.MarkErrorAsHandled() to avoid this exception.

at System.Windows.Ria.OperationBase.InvokeCompleteAction()

at System.Windows.Ria.OperationBase.Complete(Exception error)

at System.Windows.Ria.SubmitOperation.Complete(OperationErrorStatus errorStatus)

at System.Windows.Ria.DomainContext.<>c__DisplayClassb.<SubmitChanges>b__3(Object )

can you give me some help?

Thanks

Yuting

Brad,

How can I simply add a new record with your sample, and have edit fields to respect validation metadata.

Thanks,

Boris

Brad,

I repeated the same steps that you did but the Data Sources window is empty. All code is generated fine as I can use the DomainService from code behind, but the Data Source pane doesn't populate. I'm using the Visual Stuidio 2010 Professional Edition Beta 2.

Hi Brad!

I'm using the Business Template from silverlight in visual Studio 2010.

When I run the app, and open the registration window to add a new user.

and save it, a SQL Server database called ASPNETDB is created,

I need some directions how add another XAM file in the silverlight Client project

to capture or to load users stored in ASPNETDB.

Thanks,

Rachida Dukes

from a freshly installed vs2010 beta 2, using vista ultimate sqlserver 2005 express I get this;

The database 'C:\USERS\....\DESKTOP\RIASERVICE\MYAPP.STARTER\MYAPP.WEB\APP_DATA\DISHVIEW.MDF' cannot be opened because it is version 655. This server supports version 612 and earlier. A downgrade path is not supported.

Could not open new database 'C:\USERS\HENRIK\DESKTOP\RIASERVICE\MYAPP.STARTER\MYAPP.WEB\APP_DATA\DISHVIEW.MDF'. CREATE DATABASE is aborted.

An attempt to attach an auto-named database for file C:\Users\Henrik\Desktop\RiaService\MyApp.Starter\MyApp.Web\App_Data\DishView.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share

Are you using sql server 2008?

Regards from Sweden

Henrik

You don't need to answer my last question, I figured it out.

Brad, I have a question about the image path:

I tried to turn Imagepath to an Image control, but the only choices, I had are: TextBlock, TextBox, and combobox, what do I need to do to be able to image the image control in the dropdown of the imagepath.

if this question has no thing to do with silverlight, please direct me to the right direction.

Thanks,

Tobi, I found a workaround.

For me it worked by re-installing the Silverlight 4 Toolkit.
