I use the below code to return processes to a listview, i am trying to use a group header and no matter what i do it wont show up:

What am i doing wrong?

For Each managementObject As ManagementObject In (New ManagementObjectSearcher(theScope, objectQuery)).[Get]()
                Dim item As ListViewItem = ListView2.Items.Add(managementObject("ProcessId").ToString())
                item.SubItems.Add(managementObject("Name").ToString())
                item.Group = ListView2.Groups("Process List")
                'ListView2.Items.Add(item)
            Next

What does not show up, the items or the group header?

Here is an example:
Imports System
Imports System.Management

Public Class Form1
	Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
		Try
			Dim scope As New ManagementScope("root\CIMV2")
			Dim query As New ObjectQuery("Select * from Win32_Process")
			Dim item As ListViewItem = Nothing
			ListView1.Groups.Add(New ListViewGroup("Processes", "Process List"))
			For Each managementObject As ManagementObject In (New ManagementObjectSearcher(scope, query)).[Get]()
				item = New ListViewItem(managementObject("ProcessId").ToString())
				item.SubItems.Add(managementObject("Name").ToString())
				item.Group = ListView1.Groups("Processes")
				If Not item Is Nothing Then
					ListView1.Items.Add(item)
				End If
				item = Nothing
			Next
			ListView1.ShowGroups = True
		Catch ex As Exception
			MsgBox(ex.ToString)
		End Try
	End Sub
End Class
