Einar,

I had a great vacation ... it was for my birthday present ... 5 days on the French Riviera!! =)

I usually create context menus by hand rather than with the designer ... six of one, half dozen of the other, IMHO. Enabling/disabling or showing/hiding menu items is basically the way I would have done it too .... so, you done good. <g>

>Bonnie,
>Thanks for the reply. What is vacation? <s> Hope you had a nice relaxing time.
>I belive I solved my own problem before turkey-day (I haven't had time working on that project since then). I arrived at a solution designing the context menu using the designer and then just enabling/disabling or showing/hiding menu items as appropriate depending on which node was right-clicked. I do appreciate your code, cuz I learn a lot from it (you code very nice:).

>>>I have a treeview with my own custom treeviewnode class. The treeviewnode class keeps track of several things (like what type the node is). I want to display a different context menu when I right-click on node type #1 than when I right-click node type #2 and for another node type I might not even want the context menu to appear when I right-click.

>>>I've got a feeling that I need to use the mousedown and mouseup events in conjunction with the GetNodeAt() method to determine what node was right clicked and then display (or not) the context menu based on that.

>>>Does this seem to be the right approach? Should I create the context menus in the designer or in code? How do I display a context menu from a right-click event (without just adding the contextmenu in the property sheet)?
