Handle the ParentBarItem event

This can be achieved by handling the ParentBarItem.Popup event. Please refer the bekow code snippet which illustrates this:

C#

this.popupMenu1.ParentBarItem.Popup += new EventHandler(ParentBarItem_Popup);
private void ParentBarItem_Popup(object sender, EventArgs e)
{
   if(this.popupMenu1.IsShowing())
   {
      MenuColors.MenuLeftStripColor = SystemColors.Control;
      MenuColors.MenuBGColor = SystemColors.Control;
   }
   else
   {
      // Reset to default color
      MenuColors.MenuLeftStripColor = Color.Empty;
      MenuColors.MenuBGColor = Color.Empty;
   }
}

VB

AddHandler popupMenu1.ParentBarItem.Popup, AddressOf ParentBarItem_Popup
Private Sub ParentBarItem_Popup(ByVal sender As Object,ByVal e As EventArgs)
    If Me.popupMenu1.IsShowing() Then
       MenuColors.MenuLeftStripColor = SystemColors.Control
       MenuColors.MenuBGColor = SystemColors.Control
    Else
       MenuColors.MenuLeftStripColor = Color.Empty
       MenuColors.MenuBGColor = Color.Empty
End If
