making a custom context menu

I'd like to be able to do three things with the context menu

1. change the width
2. change the borderstyle to none
3. change the back color

I don't think it's possible, so what's the best way to make my own menu-like
control?

TIA,
Bob
 
Bob,
I'm not sure about #2, but #1 & #3 you can easily do with Owner Draw menus.
If you can do #2 I suspect it will need to be down with Owner Draw menus as
well...

For owner draw menus I normally derive a new class from MenuItem, set the
OwnerDraw property to yes in the constructor, then override the
OnMeasureItem & OnDrawItem methods.

The trick is the menu designer does not understand these derived classes,
what I do is design the menu as normal, then very carefully modify the
"Windows Form Designer generated code" to change
System.Windows.Forms.MenuItem to MyProject.MyMenuItem.

You can do it without deriving a class by handling the MeasureItem &
DrawItem events, however its not as clean (OOP) as deriving a class.

For more complete samples of OwnerDraw MenuItems you can refer to the source
at
www.dotnetmagic.com or Charles Petzold's book "Programming Microsoft Windows
with Microsoft Visual Basic.NET" has a sample.

Hope this helps

You will find a simple sample for an ownerdrawn menu here:

Bob,
I forgot that dot net magic recently started charging for source.

As the download I have had the source in it.

Thanks for reminding me.
