How to SelectAll in TextBox when TextBox gets focus by mouse click?

Question

If you click into the adress bar of the internet explorer, the adress will get selected. Only the second click sets the caret into the mouse position.

 

I'd like to have this in my TextBox. I tried to override OnGotFocus and call SelectAll(), but this only works if the TextBox gets it focus by keyboard. If the TextBox is clicked by mouse, the text is selected for a split second, then it is deselected again and the caret is set.

 

Thanks,
Sam

This should give you a TextBox with behaviors similar to the IE address bar:

 

Code Block

 

<TextBox

    MouseDoubleClick="SelectAddress"

    GotKeyboardFocus="SelectAddress"

    PreviewMouseLeftButtonDown="SelectivelyIgnoreMouseButton" />

 

 

Here's the code behind:

 

Code Block

 

private void SelectAddress(object sender, RoutedEventArgs e)

{

    TextBox tb = (sender as TextBox);

    if (tb != null)

    {

        tb.SelectAll();

    }

}

 

private void SelectivelyIgnoreMouseButton(object sender,

    MouseButtonEventArgs e)

{

    TextBox tb = (sender as TextBox);

    if (tb != null)

    {

        if (!tb.IsKeyboardFocusWithin)

        {

            e.Handled = true;

            tb.Focus();

        }

    }

}
