Add a check for the Enabled property:

C#

if ((myControl.GetType() == typeof(TextBox)) || (myControl.GetType() == typeof(ComboBox)))
    {
    //myControl.Text = myControl.Text.Trim();
    if (myControl.Enabled && string.IsNullOrWhiteSpace(myControl.Text))
        {
        MessageBox.Show(myControl.Name.Substring(3).ToString() + " is ");
        myControl.Focus();
        return true;
        }
    myControl.Text = TrimBetween(myControl.Text);
    }

BTW: I have removed the Trim, and changed the check - if you use the IsNullOrWhiteSpace method it does that for you.
