I’m missing something I’m sure is simple – help please?

I have a RadDropDownButton that contains a TreeView. It’s pretty straightforward, I just want them to select one value, no checkboxes or anything like that. I cannot seem to figure out the syntax to get the selected item from the TreeView.

Here is the XAML code that creates the user control:

<telerik:RadDropDownButton Content="Click to Select Charts" Click="RadDropDownButton_Click">

<telerik:RadDropDownButton.Background>

<LinearGradientBrush>

<GradientStop Color="#FFE6FFFF" Offset="0.028999984264373779" />

<GradientStop Color="#FFBDEBEF" Offset="1" />

</LinearGradientBrush>

</telerik:RadDropDownButton.Background>

<telerik:RadDropDownButton.DropDownContent>

<telerik:RadTreeView IsOptionElementsEnabled="False" IsTriStateMode="False" x:Name="tvStudentCharts" >

<telerik:RadTreeViewItem x:Name="tviStudentChart" Header="Available Charts" IsExpanded="True"

ItemsSource="{Binding StudentChartsCategories}"

ItemTemplate="{StaticResource StudentChartsCategoryTreeViewTemplate}">

</telerik:RadTreeViewItem>

</telerik:RadTreeView>

</telerik:RadDropDownButton.DropDownContent>

</telerik:RadDropDownButton>

This is included on another page:

<local:ctrlCdbStudentChartSelection x:Name="Zone1Selection" Margin="6,25,6,2" Width="200" Height="30" HorizontalAlignment="Left" Visibility="Collapsed"/>

I can see the value I want, but can’t seem to access it. I’ve tried syntax like Zone1Selection.tvStudentCharts.SelectedValues, but that doesn’t get to the URL value I want. What am I missing?

Attached is the watch showing what I’m trying to get to.

Thanks!
