Get The instance of StackPanel in above mentioned code

[gautham]

Hello I tried your code, but in the starting stage itself code fail.
  by returning zero "int count = System.Windows.Media.VisualTreeHelper.GetChildrenCount(parent);"
  Here, I am providing full structure of my code

<Grid x:Name="uxMainGrid" Height="470" Width="1000">
        <Grid.Resources>
            <ControlTemplate x:Name="uxContentControlWithFooterControlTemplate" x:Key="ContentControlWithFooterControlTemplate"
                              TargetType="ContentControl">
                <Grid>

                    </Grid.RowDefinitions>
                    <ContentPresenter x:Name="uxContentControlWithFooterControlPresenter"  Content="{TemplateBinding Content}" Grid.Row="0" />
                    <StackPanel x:Name="uxFlightEntryDisplayfooterStackPanel" Background="Red" Orientation="Vertical"  Grid.Row="1">
                        <TextBlock x:Name="uxFlightEntryDisplayfooter"  Text="{Binding FlightEntryDisplayfooter}" TextWrapping="Wrap"/>
                    </StackPanel>
                </Grid>

            </ControlTemplate>
        </Grid.Resources>

Hello,

         In order to write Test code.

 StackPanel sp2 = null;
            this.GetStackPanel(this.view.uxContentControlWithFooterTelerikControlTemplate, ref sp2);

            var sp1sp1TextBox = sp1.Children.Where(w => w.GetType().Equals(typeof(TextBlock))).Select(s => s as TextBlock).SingleOrDefault();


 private void GetStackPanel(UIElement parent, ref StackPanel st)
        {
            int count = VisualTreeHelper.GetChildrenCount(parent);
            if (count > 0)
            {
                for (int i = 0; i < count; i++)
                {
                    var child = (FrameworkElement)VisualTreeHelper.GetChild(parent, i);
                    if (child != null && child.Name.Equals("uxFlightEntryDisplayfooterStackPanel"))
                    {
                        st = child as StackPanel;
                        return;
                    }
                    GetStackPanel(child, ref st);
                }
            }
        }

Hi Gautham,

It sounds like the template of the ContentControl is not applied when you code is called. Because of that the SplitContainer is not created yet and it is not in the visual tree. What I could suggest you is to call the code after the ContentControl is loaded (hook up to its Loaded event).

One more suggestion - in order to cut off some lines of code you could use one of the extension methods, that come with RadControls for Silverlight - ChildrenOfType, that is a generic method that retrieves all visual children of a specified UIElement of a specified type. Note that this extension method is meant to be used only in tests. Here is an example how to use it in your case:

StackPanel stackPanel = this.view
                    .uxContentControlWithFooterTelerikControlTemplate
                    .ChildrenOfType<StackPanel>()
                    .First(sp => sp.Name.Equals("uxFlightEntryDisplayfooterStackPanel"));
TextBlock tb = stackPanel.Children.OfType<TextBlock>().SingleOrDefault();
