Programmatic Focus behaves different than tab or selecting

[danparker276]

Then I click on a MaskedTextInput, it's all selected and in insert mode, so if I have '8888' in the value and press 1, everything is replaced by 1.

When I set the focus on the code behind, I press '1' and get '1888' then when I press 1 again I get '11888' .  It's very strange behavior.

I have some sample code below.  When you press the button I programmatically set the focus on the RadMaskedTextInput.  Compare this to when you selected it with a mouse, or tab to it:

        private void btnTest_Click(object sender, RoutedEventArgs e)
        {
            tbClid.Value = "8888";
            tbClid.Focus();

        }

        {

            tbTest.Text = "9999";

            tbTest.Focus();
            tbTest.SelectAll();
        }
    }
}
