Tab Page ContextMenuStrip AddHandler

Good evening,
Im trying to add a ContextMenu strip to a tab page which adds different items, depending on the tab created.

I have 2 problems, the first is when I run the line 'tp.ContextMenuStrip.Items.Add("Close this")' I get 'Object reference not set to an instance of an object.'

And if I set it as a context menu and add a static menu (not what I wanna do), my handeler doesnt work.

Any ideas?

Dim tp As New TabPage

            tp.Text = "Transactions for '" & e.ClickedItem.Text & "'"
            tp.ContextMenuStrip.Items.Add("Close this")
            tp.ContextMenuStrip.Items.Add("Close all but this")
            tp.ContextMenuStrip.Items.Add("Close all")

            AddHandler tp.ContextMenuStrip.Click, AddressOf tabContextMenuStripClick

            tcWindows.TabPages.Add(tp)






    Private Sub tabContextMenuStripClick(ByVal sender As System.Object, ByVal e As System.EventArgs)

    End Sub
