    I'd like to set the text in a textblock in backcontent through code-behind. How do I do this? Here is my XAML:

    <telerikPrimitives:RadHubTile Message="" Height="171" Name="tileToday" Title="Tile Title" VerticalContentAlignment="Bottom" VerticalAlignment="Bottom"  Background="{StaticResource PhoneAccentBrush}" Width="171">
            <Border Background="{StaticResource PhoneAccentBrush}">
                <TextBlock Margin="6,6,6,6" TextWrapping="Wrap" HorizontalAlignment="Center"
        Text="** What I'd like to change **"/>

    Hello Paul,

    Thanks for the question.
    Since the back content of the hub tile is inside a data template, you will not have an auto-generated field if you set x:Name to your text block. In order to do it, you need to find the text block manually. Fortunately this case occurs a few times in our controls so we have a class that does just that. Assuming your hub tile is named hubTile and the text block in the back content named textBlock, to find the text block you have to do this:

    TextBlock textBlock = ElementTreeHelper.FindVisualDescendant<TextBlock>(this.hubTile, (child) => (child as FrameworkElement).Name == "textBlock");

    It is important to note that this code example will only work after the layout algorithm of the hub tile has passed because in Silverlight, DataTemplate objects are loaded during layout.

    Please write again if you need further assistance.
