How to edit ExpandableContentTemplate in Blend

Question

I'm using Telerik RadExpanderControl in my Wp8 app. I open the project in Blend, right-click the RadExpanderControl under Objects and Timeline, select Edit Additional Templates. Here my options are Edit Generated Content (ContentTemplate), Edit AnimatedIndicatorContentTemplate and Edit ExpandedStateContentTemplate.

None of these actually provide me access to the ExpandableContentTemplate which is what I need.

Am I missing something?

Unfortunately, is isn't available as an extractable template. However you can do this to create one:

 <telerikPrimitives:RadExpanderControl.ExpandableContentTemplate>
    <DataTemplate>
        <StackPanel Margin="24, 4, 4, 4" Orientation="Horizontal">
            <TextBlock 
                FontSize="{StaticResource PhoneFontSizeExtraLarge}" 
                FontFamily="{StaticResource PhoneFontFamilyLight}" 
                Text="{Binding TextYouWantToBind}" 
                VerticalAlignment="Center"/>
        </StackPanel>
    </DataTemplate>
</telerikPrimitives:RadExpanderControl.ExpandableContentTemplate>

A workaround that I do when I need to use Blend to style the ExpandableContentTemplate is to style the DataTemplate of the (Generated)ContentTemplate to my liking, then copy paste it into the DataTemplate of the ExpandablecontentTemplate.

I have reported this to the windows Phone Team
