title: Combobox back color in VB.NET
body: <p>I have an issue with a combobox. When I save data but the combobox is empty, it should appear in red. Instead, only items of the combo are in red.</p>
  
  <p>Here is the code I used :</p>
  
  <blockquote>
    <p>lstModGAct.BackColor = Drawing.Color.Red</p>
  </blockquote>
  
  <p>And here is my combo </p>
