If you have a click event attached to the button then you can use the below code to get the datakey value of current selected item

Protected Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        'Get the selected listview item
        Dim item As ListViewItem = TryCast(TryCast(sender, Button).NamingContainer, ListViewItem)
        'Get the datakey from listview
        'Change the listview id and datakey name here
        Dim idvalue As Integer = CInt(ListView1.DataKeys(item.DataItemIndex).Values("YourDataKeyName"))
    End Sub
