[Solved] TreeListView set selected child item mvvm not work

[kity]

TreeListView set selected child item mvvm

SelectedItem="{Binding}" work only for a first level(parent nodes), not for a child.

I am familiar with "SelectionChanged" event, but I want to not use. Can you provaid information for MVVM Selected Item for ChildTableDefinitions.

If select first level SelectedService property work, if select some of child setter of property not work.

XAML:

<telerik:RadTreeListView ItemsSource="{Binding Services, Mode=TwoWay}" SelectedItem="{Binding Path=SelectedService, Mode=TwoWay}" SelectionMode="Single" >

<telerik:RadTreeListView.ChildTableDefinitions>
<telerik:TreeListViewTableDefinition ItemsSource="{Binding Details}" />
</telerik:RadTreeListView.ChildTableDefinitions>

<telerik:RadTreeListView.Columns>
<telerik:GridViewDataColumn Header="Status" Width="Auto" IsReadOnly="True">
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Ellipse Fill="{Binding StrokeHex, Converter={StaticResource HexToSolidColorBrushConverter}, Mode=TwoWay}" Stroke="Black" Width="24" Height="24" />
</StackPanel>
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>
</telerik:RadTreeListView.Columns>

</telerik:RadTreeListView>

VIEWMODEL:

[Display(AutoGenerateField = false)]
public ObservaryModel SelectedService
{
get { return _selectedService; }
set
{
if (_selectedService != value)
{
_selectedService = value;
RaisePropertyChanged(() => SelectedService);

}
}
}

See Attach image - have two node and x2 childs.

---MODEL--

public class ObservaryModel : ServiceModel
    {
        private IList<ServiceModel> _details = new List<ServiceModel>();

        [Display(AutoGenerateField = false)]
        public IList<ServiceModel> Details
        {
            get { return _details; }
            set { _details = value; }
        }

        public ObservaryModel(){}
    }

Same problem here.

Did you find a solution?

[Rob Conley]

Actually, I'm not having that problem anymore. Not sure what I did to fix it.

The only one solution is to use equal class for Node(master) and child(detail).
Your master and detail must use the same class.

Why telerik have bug when use classes that have inherited between, I do not know.

I'm having the same issue!!! Not sure how to solve it. And Telerik doesn't respond or fix it. What a Great product ever!

Hello,

By design, RadTreeListView is meant to be used with homogeneous data only. This is documented in the Getting Started section of the control. Can you please check it out?
