On Enter Key is pressed,the focus should move from one control to another

Hi,
Please try this

I take ComboBox and datapicker controls in silverlight.

  private void comboBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Key.Equals(Key.Enter))
            {
                datePicker1.Focus();
            }
        }

 private void datePicker1_KeyUp(object sender, KeyEventArgs e)
        {
            if (e.Key.Equals(Key.Enter))
            {
                comboBox1.Focus();

            }
        }

 private void datePicker1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Key.Equals(Key.Enter))
            {
                comboBox1.Focus();

            }
        }

Thanks.
