Question

I need to populate a context menu from a database at run time. I do not know the number of items that will be in the list, so I would like to handle the click event in a single place. How do I declare the handler so I can tell which menu item actually triggered the click.

Public Function GetBookmarkContextMenu(ByVal aBookmark As Bookmark) As System.Windows.Controls.ContextMenu      Dim myContextMenu As New Controls.ContextMenu     myContextMenu.Name = 'BookmarkMenu'                For Each aMailingList As MasterService.FalconBookmarkMailingListType In GlobalUserSettings.MailingLists                  Dim mySubMenuItem As New Controls.MenuItem                 mySubMenuItem.Name = 'MailingListName' & aMailingList.ID.ToString                 mySubMenuItem.Header = aMailingList.Title                 AddHandler (myMenuItem.Click), AddressOf ForwardToList_Click                 mySubMenuItem.IsEnabled = True                 myMenuItem.Items.Add(mySubMenuItem)             Next             myContextMenu.Items.Add(myMenuItem)              return myContextMenu End Function  Public Sub ForwardToList_Click()     'How do I know which of the dynamically created items was clicked? End Sub 

Answer 1

Your ForwardToList_Click() should include parameters for the sender and event args:

Public Sub ForwardToList_Click(sender As Object, e As EventArgs) '... End Sub 

‘sender’ is the control that caused the event, which is what I believe you’re looking for.
