ContextMenu Problem

Hi

I have the following problem
I'm trying to create a dynamic ContextMenu (used by a NotifyIcon), but when I repopulate the submenus the submenus won't show. the little arrow is there - indicating that there are submenues available - but they won't popup

On the ContextMenu objects Popup eventhandler i have the routine that populates/repopulates the submenus
The submenues is populated like this

menuConnect.MenuItems.Clear()
menuDisconnect.MenuItems.Clear()
string[] names = reg.GetSubKeyNames()
for (int i=0; i<names.Length; i++)
if (names.ToLower().Equals("startup") || names.ToLower().Equals("")) continue
menuConnect.MenuItems.Add(new MenuItem(names, new EventHandler(menuConnect_Click)))
menuDisconnect.MenuItems.Add(new MenuItem(names, new EventHandler(menuDisconnect_Click)))


where menuContent and menuDisconnect are menuitems added to the contextMenu in design-time
Any help is appriciated. I've run out of ideas on how to solve this

The menu "looks" like this
Exi
Setting
------ (break
Connec
- Submenu to Connect her
Disconnec
- Submenu to Disconnect her

You are trying to assign the same menu item name to both connect and disconnect.. See your code modified in this pop up routine

Hi Fredrik

Try deleting the top level menu items and then add them again so, in your menu structure ..

The menu "looks" like this
Exi
Setting
------ (break
Connec
- Submenu to Connect her
Disconnec
- Submenu to Disconnect her

1) Delete the Connect and Disconnect menu item
2) Create new Menu Items for Connect and Disconnec
3) Add the sub-menu items to the Connect and Disconnec
4) Add the Connect and Disconnect menu items back to the main menu

e.g

menuConnect.MenuItems.Clear()
menuDisconnect.MenuItems.Clear()

// Remove menuConnec
// Remove menuDisconnec

// Create new menuConnec
menuConnect = new MenuItem( "Connect" ); // et

// Create new menuConnec
menuDisconnect = new MenuItem( "Disconnect" ); // et

string[] names = reg.GetSubKeyNames()
for (int i=0; i<names.Length; i++)
if (names.ToLower().Equals("startup") || names.ToLower().Equals("")) continue
menuConnect.MenuItems.Add(new MenuItem(names, new EventHandler(menuConnect_Click)))
menuDisconnect.MenuItems.Add(new MenuItem(names, new EventHandler(menuDisconnect_Click)))

I am not sure why but i had exactly the same problem and this worked fine :
