WPF - Remove focus when clicking outside of a textbox

Question

I have some textboxes where I would like focus to behave a little differently than normal for a WPF application. Basically, I would like them to behave more like a textbox b

Another way that worked for me was using

Mouse.AddPreviewMouseDownOutsideCapturedElementHandler

For example, say you had a TextBlock that when clicked, should become editable by showing a focused TextBox. Then when the user clicked outside the TextBox, it should be hidden again. Here's how you can do it:

private void YourTextBlock_OnMouseDown(object sender, MouseButtonEventArgs e)
{
    YourTextBox.Visibility = Visibility.Visible;
    YourTextBox.Focus();
    CaptureMouse();
    Mouse.AddPreviewMouseDownOutsideCapturedElementHandler(this, OnMouseDownOutsideElement);
}

private void OnMouseDownOutsideElement(object sender, MouseButtonEventArgs e)
{
    Mouse.RemovePreviewMouseDownOutsideCapturedElementHandler(this, OnMouseDownOutsideElement);
    ReleaseMouseCapture();
    YourTextBox.Visibility = Visibility.Hidden;
}
