How to keep context menu open after selection

Question

My context menu has multiple menu items, each of which contains a listbox with the selections. After the user selects an item from the listbox, the context menu closes. I want to force the context menu to stay open, so the user can move to the next menu item and select from its list box. I've tried using contextMenu.StaysOpen = true; and menuItem.StaysOpenOnClick; however, I can't get the menu to stay open.

Here is a snippet of my code:

contextMenu = new ContextMenu();

enrMenuItem = new MenuItem();
enrMenuItem.StaysOpenOnClick = true;
enrMenuItem.Header = "Enrichment";
enrMenuItem.Items.Add(enrMenuListBox);
contextMenu.Items.Add(enrMenuItem);

gadMenuItem = new MenuItem();
gadMenuItem.StaysOpenOnClick = true;
gadMenuItem.Header = "Gadolinia";
gadMenuItem.Items.Add(gadMenuListBox);
contextMenu.Items.Add(gadMenuItem);

contextMenu.IsOpen = true;

Make sure you are using .net 3.0 up. Otherwise, just store the position of the popup when shown and when a selection is made (of when hidden) just show it again at the stored position.

Good luck!

Thanks so much for your answer. I understood it to say that I should store the position and re-show if I'm not using .net 3.0 or up. I am using .net 3.5, so is there something different you would suggest for .net 3.0 and up?

Maybe you could use the StaysOpen property of the ContextMenu. You are now only setting the MenuItem property and this is not exacly what you want I guess. It should now stay open until you set the IsOpen property to false yourself.

Good luck!
