How to retrieve column items from listview in code

How to retrieve column items from listview in code

I am new to wpf and am going for an MCTS exam. I have searched for 2 days
now on how to retrieve row column items in code. I have been able to
insert data into the listview by creating a structure and adding row items
via code.
Public Structure SimpleData
Public Property Txt1 As String
Get
Return mTxt1
End Get
Set(value As String)
mTxt1 = value
End Set
End Property
Private mTxt1 As String
Public Property Txt2 As String
Get
Return mTxt2
End Get
Set(value As String)
mTxt2 = value
End Set
End Property
Private mTxt2 As String
Public Property Txt3 As String
Get
Return mTxt3
End Get
Set(value As String)
mTxt3 = value
End Set
End Property
Private mTxt3 As String
End Structure
Public Structure MyData
Public Property Desc() As String
Get
Return m_Desc
End Get
Set(value As String)
m_Desc = Value
End Set
End Property
Private m_Desc As String
Public Property Progress() As Integer
Get
Return m_Progress
End Get
Set(value As Integer)
m_Progress = Value
End Set
End Property
Private m_Progress As Integer
Public Property ProgressText() As String
Get
Return m_ProgressText
End Get
Set(value As String)
m_ProgressText = Value
End Set
End Property
Private m_ProgressText As String
Public Property Pic() As String
Get
Return m_Pic
End Get
Set(value As String)
m_Pic = Value
End Set
End Property
Private m_Pic As String
End Structure
Private Sub Button2_Click(sender As System.Object, e As
System.Windows.RoutedEventArgs) Handles Button2.Click
Dim sd As New SimpleData
sd.Txt1 = "Today is"
sd.Txt2 = "a good day"
sd.Txt3 = "O YES!"
listView1.Items.Add(sd)
End Sub
I want to be able to retrieve row(0).Item(0).ToString, which is how to
retrieve it in win forms. Expecting a response. Thanks in advance
