The events of the above code are given below.

[C#]

        void HandleMouseInput(object sender, MouseEventArgs args)
        {
            TextBox tb = args.Source as TextBox;
            if (tb == null)
                return;
            if (ActiveTextBox == null)
                Activate(tb);
            else
                Deactivate(ActiveTextBox);
        }

        //Deactivates the active TextBox if the Enter
        // or ESC key is pressed.

        void HandleKeyInput(object sender, KeyEventArgs args)
        {
            TextBox tb = args.Source as TextBox;
            if (tb != null &&
                  (args.Key == Key.Return || args.Key == Key.Escape))
                Deactivate(tb);
        }

        //Deactivate the Textbox the active TextBox.
        void HandleLostFocus(object sender, EventArgs args)
        {
            TextBox tb = sender as TextBox;
            if (tb != null)
                Deactivate(tb);
        }

        //Activate the TextBox by applying the base style
        //(thereby removing the basic style.)  Set focus, select
        //all the content & invalidate the visual.
        //Also, dynamically add handlers for losing focus and
        //handling key input.

        void Activate(TextBox tb)
        {
            tb.Style = (Style)tb.FindResource('TextBoxBaseStyle');
            tb.Focus();
            tb.SelectAll();
            tb.InvalidateVisual();
            tb.LostFocus += new RoutedEventHandler(HandleLostFocus);
            tb.KeyDown += new KeyEventHandler(HandleKeyInput);
            ActiveTextBox = tb;
        }

        //Deactivate the TextBox by applying the Basic style.
        //Remove the event handlers.

        void Deactivate(TextBox tb)
        {
            tb.Style = (Style)tb.FindResource('BasicTextBox');
            tb.LostFocus -= new RoutedEventHandler(HandleLostFocus);
            tb.KeyDown -= new KeyEventHandler(HandleKeyInput);
            ActiveTextBox = null;
        }

If the resource string is named ‘CopyrightInfo’ for example, then you can bind it to the TextBlock as follows:

<TextBlock Text='{x:Static local:Resource1.CopyrightInfo}'/>

Where the ‘local’ should be mapped to Resource1.resx’s namespace (you can find out by opening the resx’s code-behind file).

This is very easy to do in XAML, as follows:

[XAML]
        <TextBlock x:Name='myTextBlock' Width='100' Height='40'>
            <Button>Test</Button>
        </TextBlock>

And you can do something similar in C# as follows:

[C#]
            Button btn = new Button();
            btn.Content = 'Test';
            this.myTextBlock.Inlines.Add(btn);
