Databinding and CurrentItem

[madladuk]

Hi. I have a treeview bound to my ria domain collection, however when I select an item in the try the current record is not changed. Is the treeview not dataaware? or have I missed something?

<telerik:RadTreeView x:Name="radTreeView1"
                             Margin="0,5,5,5"
                             IsLineEnabled="True"
                             SelectionMode="Single"
                             IsEditable="False"
                             IsDragDropEnabled="False"
                             ItemsSource="{Binding}"
                             ItemTemplate="{StaticResource Persons}"

Thanks

Hi madladuk,

 You can bind the IsSelected property of the RadTreeViewItems  to property of an item in the RIA collection ( you have to use ContainerBindings --> http://www.telerik.com/help/silverlight/radtreeview-how-to-bind-hierarchical-data-use-containerbindingcollection.html ).

Supposing that you  use a DomainDataSource to bind your RadTreeView, a key moment is handling the RadTreeView.SelectionChanged event like so:

private void myTreeView_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangedEventArgs e)
        {
            MyDataSource.SubmitChanges();
        }

Hope this info helps you. Please feel free to let us know if you need further assistance.
