Transparent contextmenustrip image margin

[Edgemeal]

Surely this can simply be over ridden by using Me.BackColor = Color.Transparent :/ you would of thought any way.

I've never done anything like that so don't really have a clue, I also don't have WinXP, but using Win7 I added this to your class,...

Protected Overrides Sub OnRenderImageMargin(e As System.Windows.Forms.ToolStripRenderEventArgs)
    ' by disabling the line below the image margin is now transparent. (Win7 test only)
    'MyBase.OnRenderImageMargin(e)
End Sub

For testing I did this and attached an image of what my menu looks like.

Dim mymenu As New ContxtMenu ' < class name changed due to conflict.
mymenu.BackColor = Color.Coral
mymenu.Items.Add("Testing 123", My.Resources.eventlog.ToBitmap)
mymenu.Items.Add("Testing 456", My.Resources.eventlogInfo.ToBitmap)
mymenu.Items.Add("Testing 789", My.Resources.eventlogWarn.ToBitmap)
Me.ContextMenuStrip = mymenu
