I convert my dynamic-data web application(not, web-site) CTP to Preview version. Recently.

But, I have error-message, help me please.

CTP version 

   protected void Page_InitComplete(object sender, EventArgs e)
    {
            DynamicGridView1.InitializeMaster(/*loadForeignKeys*/true);
            DynamicGridView1.RegisterDetails(DynamicDetailsView1, /*loadForeignKeys*/true);
    }

Preview version

    <asp:DynamicDataManager ID="DynamicDataManager1" runat="server" EnableQueryStringSelection="true" AutoLoadForeignKeys="true" /> (at ASPX)

   protected void Page_InitComplete(object sender, EventArgs e)
    {
            DynamicDataManager1.RegisterControl(GridView1);
            DynamicDataManager1.RegisterControl(DetailsView1);
    }

Error Message Shown:

Let me know how can i fix this problem.

Have you modified your Global.asax file to register your data context? 

I added global.asax.
Now, there is no problem.

Thank you a lot.
