Public Class Form1
    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        kodebarang.Items.Add("TS001")
        kodebarang.Items.Add("TS002")
        kodebarang.Items.Add("VG001")
        kodebarang.Items.Add("VG002")
        RancangTable()
    End Sub
    Sub RancangTable()
        ListView1.Columns.Add("No Pembelian", 80, HorizontalAlignment.Center)
        ListView1.Columns.Add("Kode Barang", 100, HorizontalAlignment.Center)
        ListView1.Columns.Add("Nama Barang", 100, HorizontalAlignment.Center)
        ListView1.Columns.Add("Merek", 100, HorizontalAlignment.Center)
        ListView1.Columns.Add("Harga", 100, HorizontalAlignment.Center)
        ListView1.Columns.Add("Jumlah Beli", 100, HorizontalAlignment.Center)
        ListView1.Columns.Add("Total Harga", 100, HorizontalAlignment.Center)
        ListView1.View = View.Details
        ListView1.FullRowSelect = True
        ListView1.GridLines = True
    End Sub


   

    Sub IsiTable()
        Dim list As New ListViewItem
        list.Text = nopembelian.Text
        list.SubItems.Add(kodebarang.Text)
        list.SubItems.Add(namabarang.Text)
        list.SubItems.Add(merk.Text)
        list.SubItems.Add(harga.Text)
        list.SubItems.Add(jumlahbeli.Text)
        list.SubItems.Add(totalharga.Text)
        ListView1.Items.Add(list)
    End Sub

   
   
    Private Sub Kode_Barang_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles kodebarang.SelectedIndexChanged
        Dim x As String
        x = Microsoft.VisualBasic.Left(kodebarang.Text, 2)
        Select Case x
            Case "TS"
                merk.Text = "Toshiba"
            Case "VG"
                merk.Text = "V-Gen"
        End Select

        Dim j As String
        j = Microsoft.VisualBasic.Right(kodebarang.Text, 3)
        Select Case j
            Case "001"
                namabarang.Text = "Flashdisk 4 GB"
            Case "002"
                namabarang.Text = "Flashdisk 2 GB"
        End Select

        Select Case x & j
            Case "TS" & "001"
                harga.Text = 105000
            Case "TS" & "002"
                harga.Text = 75000
            Case "VG" & "001"
                harga.Text = 90000
            Case "VG" & "002"
                harga.Text = 60000
        End Select
    End Sub

    Private Sub Jumlah_Beli_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles jumlahbeli.KeyPress
        Dim x As Integer = Asc(e.KeyChar)
        If x = 13 Then
            totalharga.Text = harga.Text * jumlahbeli.Text
        End If
    End Sub

    Private Sub Simpan_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSimpanKeListView.Click
        IsiTable()
    End Sub

    Private Sub Bersih_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnBersih.Click
        nopembelian.Text = ""
        kodebarang.Text = ""
        namabarang.Text = ""
        merk.Text = ""
        harga.Text = ""
        jumlahbeli.Text = ""
        totalharga.Text = ""
    End Sub

    Private Sub Hapus_Semua_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnHapusSemuaData.Click
        ListView1.Items.Clear()
    End Sub

    Private Sub HapusData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnHapusDataYangDiPilih.Click
        ListView1.Items.Remove(ListView1.SelectedItems(0))
    End Sub

    Private Sub Keluar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButnKeluar.Click
        End
    End Sub
End Class

dan inilah hasilnya :
