Answer 1

You need to DataBind TextBlock Text (?) element to your class - like so:

In XAML

<TextBlock x:Name="MyTextBlock"
   Text={Binding ShowThis, Mode=OneWay} />

in class:

 public class MyDataContextClass
 {
     private string showThis = string.Enpty;
     public string ShowThis
     {
         get {return showThis;}
         set
         {
              showThis = value;
              if (PropertyChanged != null)
                  PropertyChanged(....);
         }
      }
  }

and you must DataBing Xaml to class. (May be in constructor ?)

  public class MyXamlWindow
  {
       public MyXamlWindow()
       {
             this.DataContext = new MyDataContextClass();
       }
   }

There's a lot of ways to do all above

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.
