Hello,

I am very glad that the approach I suggested is helpful for you.  When using the GetDescendantFromType method, you will get the first element from type T which is in the visual tree of first parameter of the method. I have created a method for you that will allows you to get all elements from given type in the visual tree of an element. Here is the method and how can be used:

Xaml:

<Window x:Class="GetAllChildrenFromTypeTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Button Content="Button" 
                Height="75"  
                Name="button1" 
                Width="75" Click="button1_Click">
            <Button.Template>
                <ControlTemplate TargetType="Button">
                    <Grid Background="Green">
                        <StackPanel>
                            <ContentPresenter Content="{TemplateBinding Content}"/>
                            <ContentPresenter Content="{TemplateBinding Content}"/>
                            <ContentPresenter Content="{TemplateBinding Content}"/>
                            <ContentPresenter Content="{TemplateBinding Content}"/>
                        </StackPanel>
                    </Grid>
                </ControlTemplate>
            </Button.Template>
        </Button>
    </Grid>
</Window>

C#:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        List<ContentPresenter> elements = new List<ContentPresenter>();
        GetAllChildrenFromType(sender as DependencyObject, elements);
    }

    private void GetAllChildrenFromType<T>(DependencyObject parent, List<T> elements) where T : DependencyObject
    {
        if (elements == null)
            elements = new List<T>();

        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(parent); i++)
        {
            if (VisualTreeHelper.GetChild(parent, i) is T)
            {
                elements.Add(VisualTreeHelper.GetChild(parent, i) as T);
            }
            else
            {
                GetAllChildrenFromType<T>(VisualTreeHelper.GetChild(parent, i), elements);
            }
        }
    }
}
