Hierarchy Like WinForms

[Erik Van Norstrand]

Hey all,

Does anyone know how to build a hierarchical TreeView like we have the ability to do in WinForms.

In WinForms I can do:

radTreeView1.DataSource = industryCodeList;
radTreeView1.DisplayMember = "Description";
radTreeView1.ValueMember = "IndustryCode1";
radTreeView1.ParentIDMember = "ParentIndustryCode";

I would then get a hierarchical TreeView that was really simple to use.

Thanks,
Erik Van Norstrand

Hello Erik Van Norstrand,

If you want to display hierarchical data, you could use the HierarchicalDataTemplates to define the RadTreeView's hierarchical data structure. You can read more about them here in our help.

Below, you can find a sample code snippet of binding this control to hierarchical data

    <Window.Resources>
           <HierarchicalDataTemplate x:Key="SampleTemplate"
                       ItemsSource="{Binding Sub}" >
               <TextBlock Text="{Binding Name}"/>
           </HierarchicalDataTemplate>
   </Window.Resources>
   <Grid>
       <telerik:RadTreeView x:Name="radTreeView"
           ItemTemplate="{StaticResource SampleTemplate}"/>
   </Grid>

ObservableCollection<HierarchicalClass> source = new ObservableCollection<HierarchicalClass>();
source.Add(new HierarchicalClass() { Name = "Item 1" });
radTreeView.ItemsSource = source;

where the HierarchicalClass provides the hierarchicy. More about this here.
