c# - how to get the children of an element WPF

I have a stackpanel that contains an Image and a TextBlock. I'm raising an event once double click is being performed by the user.(P.S - I'm adding the StackPanel and it's children (the Image and the TextBlock programatically if it matters).

Now, I need to get the TextBlock element from inside the stackpanel, I understand that I should do it using DataBinding, but I'm a beginner to WPF, and really haven't found any examples about it in the web. I'll be glad for an explanation, thank you very much!

(I learnt about DataBinding a while ago).

A simple way of getting the first child element of a certain type (e.g. TextBlock) is this:

var textBlock = panel.Children.OfType<TextBlock>().FirstOrDefault();

You either get the first TextBlock or null if there isn't any.
