[Angie]

I'm trying bind Following type of object collection to rad tab but i get

public ObservableCollection<INavigatableTab> TabViewCollection
       {
           get
           {
               if(_tabViewCollection == null)
                   ProcessTabViews();

               return _tabViewCollection;
           }
       }

 public void ProcessTabViews()
       {
           var infoKey = new InfoKey()
                             {
                                 AgencyID = ApplicationGlobal.Settings.AgencyInfo.AgencyID,
                                 EndorsementID = ApplicationGlobal.ActiveEndorsement.EndorsementID,
                                 PolicyNumber = ApplicationGlobal.ActiveEndorsement.PolicyNumber
                             };


           _tabViewCollection = new ObservableCollection<INavigatableTab>()
                                    {new BasicInfoViewNavigatableHandler(infoKey, new EndorsementGeneralDataService())};

       }

NVM i solved it my self. Here is the solution

<UserControl.Resources>
        <telerik:HierarchicalDataTemplate x:Key="ItemTemplate1" >
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition />
                    <ColumnDefinition />
                </Grid.ColumnDefinitions>
                <TextBlock Text="{Binding TabName}" />
            </Grid>
        </telerik:HierarchicalDataTemplate>
        <telerik:HierarchicalDataTemplate x:Key="ContentTemplate1">

            <StackPanel>
                <toolkit:TransitioningContentControl x:Name="ctlMain" Margin="10"  Content="{Binding View}" HorizontalContentAlignment="Left" />
            </StackPanel>

        </telerik:HierarchicalDataTemplate>
    </UserControl.Resources>
<telerik:RadTabControl x:Name="cntrltab"
                                  telerik:StyleManager.Theme="Windows7"
                                  MinWidth="700"  HorizontalContentAlignment="Left"
                                  SelectedIndex="{Binding CurrentTabIndex, Mode=TwoWay,FallbackValue=0}" BorderThickness="0,1,0,0"
                                  Margin="0,10,0,0" d:LayoutOverrides="HorizontalAlignment, Width, Height" Grid.Row="1"
                                  Background="{x:Null}"
                                  ItemsSource="{Binding TabViewCollection, Mode=TwoWay}"
                                  ItemTemplate="{StaticResource ItemTemplate1}"
                                  ContentTemplate="{StaticResource ContentTemplate1}">
                </telerik:RadTabControl>
