Я пытаюсь поиска в текстовое поле элемента управления datagridview

---

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtBar.TextChanged
        ' Try
        Dim sql As String = "Select Barcode,ItemName,ItemDescription,Quantity,Price from Items"

        cnn.ConnectionString = "Provider=Microsoft.ACE.Oledb.12.0; Data Source=" & Application.StartupPath & "\InventSystem.accdb"
        cnn.Open()

        Dim dataadapter As New OleDbDataAdapter(sql, cnn)
        Dim ds As New DataSet()
        Dim dsView As New DataView
        Dim bs As New BindingSource()
        dataadapter.Fill(ds, "Items")
        cnn.Close()
        dsView = ds.Tables(0).DefaultView
        bs.DataSource = dsView
        bs.Filter = "Barcode LIKE '" & txtBar.Text & "*' or ItemName LIKE '" & txtBar.Text & "*' or ItemDescription '" & txtBar.Text & "*' or Quantity '" & txtBar.Text & "*'or Price '" & txtBar.Text & "*';"
        Me.DataGridView1.DataSource = bs
        cnn.Close()
        'Catch ex As Exception
        'MsgBox(ex.ToString, MsgBoxStyle.Critical)
        ' End Try
    End Sub

Что я уже пробовал:

я получаю сообщение об ошибке

Syntax error: Missing operand after ''2*'' operator.
