[Solved] Treeview with custom Hierarchical Template and checkbox

[Michele]

Hello,
I've got a treeview with a custom hierarchical template ... I need to add a checkbox to it, with the treestate... how can I do this without having to specify the treeview checkbox behavior manually??

consider the following class

[DataContract]
  public class ListaContainer
  {
      [DataMember]
      public string NomeLista { get; set; }
      [DataMember]
      public List<Banca> Banca { get; set; }
      //[DataMember]
  }

  [DataContract]
  public class Level1
  {
      [DataMember]
      public string Descrizione { get; set; }

      [DataMember]
      public List<Level2> Level2s { get; set; }
  }

  [DataContract]
  public class Level2
  {
      [DataMember]
      public string Descrizione { get; set; }

      [DataMember]
      public List<Level3> Level3s { get; set; }
  }

  [DataContract]
  public class Level3
  {
      [DataMember]
      public string Descrizione { get; set; }

      [DataMember]
      public List<Level4> Level4s{ get; set; }
  }

  [DataContract]
  public class Level4
  {
      [DataMember]
      public string Descrizione { get; set; }

      [DataMember]
      public List<Level5> Level5s { get; set; }
  }

  [DataContract]
  public class Level5
  {
      [DataMember]
      public int IDInterno { get; set; }

      [DataMember]
      public string Descrizione { get; set; }

  }

The level 1-4 template are defined so :

<telerik:HierarchicalDataTemplate x:Key="Level2" ItemsSource="{Binding Level3s}">
                  <StackPanel Orientation="Horizontal" Height="16">

                      <Image Source="{Binding Converter={StaticResource Imageconverter},ConverterParameter=Level2}" Height="16" Width="16"  Margin=" 0,0,6,0" />
                      <TextBlock Text="{Binding Descrizione}"/>
                  </StackPanel>
              </telerik:HierarchicalDataTemplate>

While the Level 5 is :

<DataTemplate x:Key="xxx">
                   <StackPanel Orientation="Horizontal" Height="16">
                       <Image Source="{Binding Converter={StaticResource Imageconverter},ConverterParameter=xxx}" Height="16" Width="16" Margin=" 0,0,6,0" />
                       <!--<TextBlock Text="{Binding Descrizione}"/>-->
                       <HyperlinkButton Content="{Binding Descrizione}" Tag="{Binding IDInterno}" Click="HyperlinkButton_Click"></HyperlinkButton>
                   </StackPanel>
               </DataTemplate>

Thanks

Hello Paolo,

You can take advantage of the build in check box support of RadTreeVeiw. Setting the IsOptionElementsEnabled to true will add checkbox component in front of every item in the tree. Setting the IsTriStateMode to true will enable the tri-state mode behavior.

You can take a look at the following help article for more info: http://www.telerik.com/help/silverlight/radtreeview-features-checkbox-support.html#Tri-state_Check_Boxes
