Var base As New WebMenuItem

Var loadMenu As New WebMenuItem("Load")
base.Append(loadMenu)

Var saveMenu As New WebMenuItem("Save")
saveMenu.Enabled = False
base.Append(saveMenu)

Me.ContextualMenu = base

Create a new menu item and set it to be a header:

Var m As New WebMenuItem
m.Text = "Customers"
m.Style = WebMenuItem.Styles.Header

WebMenuItem.Tag

Tag As Variant

A hidden value associated with the menu item.

The tag is accessible via code when the user chooses the menu item but, unlike the Text property, is not displayed in the menu. It works like the RowTag property of a PopupMenu control.

The Tag is a variant so it can contain any value, including class references.

This code displays a menu when you right-click on a Label. This code is in the Shown event handler of a WebLabel:

Var file As New WebFile
file.MimeType = "text/plain"
file.ForceDownload = True ' If False, the browser may try to display the file instead of download it
file.FileName = "TextFile.txt"
file.Data = "Hello, world!"

Var base As New WebMenuItem

Var downloadMenu As New WebMenuItem("Download")
downloadMenu.Tag = file ' The file to download
base.AddMenuItem(downloadMenu)

Me.ContextualMenu = base

In the ContextualMenuAction event handler of the WebLabel, you can then use the tag to download the previously created file:

If Item.Text = "Download" Then
  Var file As WebFile = Item.Tag
  System.GotoURL(file.URL)
End If

WebMenuItem.Text

Text As String

The text displayed.

Set the text of the menu item to "Hobbiton":

Var menu As New WebMenuitem
menu.AddMenuItem("Frodo")
menu.AddMenuItem("Sam")
Me.ContextualMenu = menu

Right-click on the button to show the menu.

To determine which menu was selected, use this code in the ContextualMenuSelected event handler:

Select Case Item.Text
Case "Frodo"
  MessageBox("You chose Frodo.")
Case "Sam"
  MessageBox("You chose Sam.")
End Select

This code create a nested menu:

Var myMenu As New WebMenuItem

Var menuItem1 As New WebMenuItem("Dark Wizards")
Var subMenuItem1 As New WebMenuItem("Sauron")

myMenu.AddMenuitem(menuItem1)
