WPF trouble getting TextBox focused

On mouse event I'm trying to create TextBox, add it to Grid, select all and focus keyboard. But can't get it working:

private void timeCodeEdit(object sender, MouseEventArgs e)
{
    Grid grid = (Grid) ((Label) sender).Parent;
    TextBox text = new TextBox();
    text.Margin = new Thickness(0, 0, 75, 0);
    text.Text = "aaaa";
    grid.Children.Add(text);
    text.LostFocus += lostFocus;
    Keyboard.Focus(text);
    text.SelectAll();
}

I've tried Keyboard.Focus(text); and text.Focus();. And if I do this:

private void lostFocus(object sender, RoutedEventArgs e)
{
    Keyboard.Focus(sender as TextBox);
    e.Handled = true;
}

I'm getting StackOverflowException, cause it lost focus right after focus.

Maybe someone can help me about this?

I'll post answer:

text.LostKeyboardFocus += Text_LostKeyboardFocus;

and:

private void Text_LostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e) 
{ 
    var name = ((FrameworkElement)e.NewFocus).Name; 
    Console.Write(name); 
}

Helped me find out that my ScrollViewer is getting focus, so Focusable="False" for ScrollViewer solved the problem.
