(WPF) How do i grab the text of a textbox inside an ItemsControl?

Question

This is my ItemsControl in the XAML file:

            <ItemsControl x:Name="PNItemsControl">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
                        <TextBox Text="{Binding TextBoxText}" Width="150"/>
                        <Button Content="Remove" Width="50"/>
                    </StackPanel>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>

The number of Textboxes I generate varies. I want to grab the text with this code:

            string[] phoneNumbers = "";
            foreach(TextBox tb in PNItemsControl.Items.OfType<TextBox>())
            {
                phoneNumbers.Append(tb.Text);
            }
            c.PhoneNumbers = phoneNumbers;

But the ItemsControl does not see the textboxes generated. I even tried to grab the buttons or the stackpanels and still the variable (tb in this case stays null). Did I make a mistake or is there an alternative to grab items from ItemsControl?

You should loop through PNItemsControl.Children which are of type FrameworkElement ! So:

foreach(FrameworkElement in PNItemsControl.Children)

or

foreach (var element in PNItemsControl.Children.OfType<FrameworkElement>())

from there you should be able to identify your textboxes
