How to set Enter Key in a Control on Aspx page

I figured out the answer to my question. If you are using a Silverlight Application and want to use the "Enter" key to tab through TextBoxes or Controls you can do something similar to the following:

private void OnKeyDown(object sender, KeyEventArgs e)
{
        if (e.Key == Key.Enter)
{
        List controls = LayoutRoot.Children().Where(x => x.GetType().Name == "TextBox" ||         x.GetType().Name == "ComboBox").OrderBy(y => y.TabIndex).ToList();

        int indx = controls.IndexOf(e.OriginalSource as Control);

        if (indx < 0 && e.OriginalSource == btn && e.Key == Key.Enter) { // Do what you need here; // return; }

        if (indx + 1 >= controls.Count) { btn.Focus(); }
        else { controls[indx + 1].Focus(); }
}
        // Another additional add on you could use is to implement what the "Esc" key press will do as seen below
        if (e.Key == Key.Escape) { // Do what you need here; }
}

In my example I am not only using the "Enter" key to simulate a "Tab" key press, I am also counting the Controls so that when the last control is hit the "Enter" key press takes you to an "OK" button and pressing "Enter" again will click the "OK" button thus submitting a form, login control, etc.
