How to select all text in textbox when it gets focus

Question

In Windows phone, how can I select all text in Textbox when the TextBox has focus?

I try setting the get focus property of Textbox:

    private void TextBox_GotFocus(object sender, RoutedEventArgs e)
    {
        TextBox textBox = (TextBox)sender;

        textBox .SelectAll();
    }

What I see is I see all the text is being selected for 1-2 sec and then it goes back to cursor mode (i.e. 1 blink line).

I had this same problem on WPF and managed to solve it. Not sure if you can use what I used but essentially your code would look like:

    private void TextBox_GotFocus(object sender, RoutedEventArgs e)
    {
        TextBox textBox = (TextBox)sender;

        textBox .CaptureMouse()
    }

    private void TextBox_GotMouseCapture(object sender, RoutedEventArgs e)
    {
        TextBox textBox = (TextBox)sender;

        textBox.SelectAll();
    }

private void TextBox_IsMouseCaptureWithinChanged(object sender, RoutedEventArgs e)
    {
        TextBox textBox = (TextBox)sender;

        textBox.SelectAll();
    }

All events hooked up to the original textbox. If this doesn't work for you, maybe you can replace CaptureMouse with CaptureTouch (and use the appropriate events). Good luck!
