Doing this kind of thing can be helpful. Basically when you create the
menuitem you give it a unique identifier of your chosen type (here an
integer based on a database primary key but can be a string or a form
ref or an elephant). Note my scoping is sloppy.
Friend Class DataMenuItem
Inherits MenuItem
'just a menu item that retains a PK reference from creation
Public Sub New(ByVal intItemID As Integer)
DatabaseID = intItemID
End Sub
Friend DatabaseID As Integer
End Class
Whack a new menuitem on like:
MyItem = New DataMenuItem(MyInteger)
MyItem .Text = "Blah"
MyMenu.MenuItems.Add(MyItem)
Then you can CType the sender to a DataMenuItem in your click event no
worries and get your desired ID out.
Hope I have grasped your issue OK!
Cheers,
Iain

Subject: [ADVANCED-DOTNET] Name of MenuItem through Reflection
I need to extract the name of a menuitem at runtime using reflection,
but it does not have a name property or any custom property which seems
appropriate!
The situation is: I set up the security for the controls on the form
dynamically from a db in the backend using the names of the controls on
the form. Works well for everything, except the menu's, as these are
not in the controls collection.
When a menuitem recieves the "Click" event, I can identify the menuItem
by using the event parameter Sender. A MenuItem does not have a Name
property however, so I'm back to square one! I tried to extract the name
of the local variable that defines the instance (private withevents
mymenu as ....), but am struggling to get this. Can anyone help me to
extract anything unique per menu item (which is human readable as well)
or maybe help me cycle through the local variables on the form (to
compare it to the Sender object in the click event)
Thanks
