DataView not updating after a load

[plusHR]

I have a RadDomainDataSource on my page and this is passed to various user-controls that will load data base don certain events. However in the usercontrol when I do a load the DtaaView is not changed to show the new loaded items;

Definition in my main parent page

<Grid x:Name="LayoutRoot"
          Background="LightGray"
          DataContext="{Binding ElementName=dds, Path=DataView}">

Datasource is passed to the usercontrol as a property

public Telerik.Windows.Controls.RadDomainDataSource DataSource { get; set; }

Then I call a load operation

AppDomainContext ctx = this.DataSource.DomainContext as AppDomainContext;
             ctx.Load<data_PERSON>(ctx.AdminPeople_GetEmergencyContactsQuery(), LoadBehavior.MergeIntoCurrent, true);

Therefore I would then expect the DataView to change to to the new loaded entities.

Thanks
Paul

Hello Paul,

That behavior is expected and is by design.

When working with RadDomainDataSource, you are not supposed to work directly with the DomainContext anymore, since the RDDS will not "know" what is going on. Once you "give" the DomainContext to the RDDS, you should not touch anything on it.

Please use the respective RadDomainDataSource methods, for example Load if you want to load the data. Eventually, this will call DomainContext.Load in the end, but it does many other things before that.

You might find my series of blogs interesting, in case you have missed them:

• Introducing RadDomainDataSource for Silverlight
• Loading data with RadDomainDataSource for Silverlight
• An MVVM Approach to Telerik Domain Services for Silverlight
• Creating CRUD application with RadDomainDataSource for Silverlight
• Why we have built RadDomainDataSource for Silverlight?

Let me know if there are problems with the approach that I have suggested.
