Hi,

I have followed the steps described at "Using a DomainService in ASP.NET and Dynamic Data"(http://blogs.msdn.com/davidebb/archive/2009/03/24/using-domaindatasource-in-asp-net.aspx) using ASP.NET Dynamic Data 4.0 Preview 4.
The Domain Service looks like this:
public class DomainService1 : LinqToEntitiesDomainService<AdventureWorksEntities1>
    {

        // TODO: Consider
        // 1. Adding parameters to this method and constraining returned results, and/or
        // 2. Adding query methods taking different parameters.
        public IQueryable<Employee> GetEmployee()
        {
            return this.Context.Employee;
        }

        // TODO: Consider
        // 1. Adding parameters to this method and constraining returned results, and/or
        // 2. Adding query methods taking different parameters.
        public IQueryable<Product> GetProduct()
        {
            return this.Context.Product;
        }
    }

When I access Employee/List.aspx in the dynamic data website, I get the error that says:
Could not find a property or field called 'Employee' on the data context type 'DomainService1' of LinqDataSource 'GridDataSource'.

What do I need to resolve this? Any suggestions?

Thanks,
Yash

 Hi Yashgt, have you looked at the latest release of Preview 4 see: Dynamic Data Preview 4 (REFRESH) 
by scothu which has some fixes for DomainService.

Instead on LinqToSqlDataSource I have:

   <asp:DomainDataSource ID="GridDataSource1" runat="server" EnableDelete="true">
  <WhereParameters>
  <asp:DynamicControlParameter ControlID="FilterRepeater" />
  </WhereParameters>
  </asp:DomainDataSource>

Using the REFRESH DynamicData preview 4 did not help. At this line:

table = GridDataSource1.GetTable();

It gives an error saying : table expects IDynamicDataSource and we are assigning DomainDataSource.

I tried:GridDataSource1.TryGetMetaTable(out table);

But the table turns out to be null.

yashgt:

It gives an error saying : table expects IDynamicDataSource and we are assigning DomainDataSource.

I've had this error with Linq to SQL and EF and it is usually to do with not setting something i.e. the gridview does not point to the DataSource etc.

Looks like your using the wrong page templates. In preview 4 there is the ProjectTemplates/DomianServiceProject  can you confirm that you are using the right page templates? The new templates do not use the datasource's WhereParameters...

 It worked after I used the new templates. However, I had to change the DomainService to get it working as described at http://forums.asp.net/t/1443397.aspx

The UpdateEntity function is expected to take a single param, whereas the DomainService is created by default with 2 params.

I think the DynamicData team should work to resolve this.

Thanks,

Yash

 Hi Yashgt, it's worth noting that the ASP.Net Team do read this forum and provide answers, so your point will be noted also DomainService stuff is owned by the Silverlight team see here for there .NET RIA Services forum.
