Как я могу искать и фильтровать данные в datagridview с помощью radiobutton используя VB .NET и мою базу данных mysql

---

Нет ошибки в моем коде, но нет отображения данных в моем datagridview. Заранее спасибо

Что я уже пробовал:

Private Sub YearlyREp()
        Dim con As MySqlConnection = New MySqlConnection("server=localhost;user id=root;password=;database=itbcis; Convert Zero DateTime=True")
        Dim Content As String

        If (RBproducts.Checked = True) Then
            Content = "Bondpaper" & "Ballpen" & "Pentelpen" & "Ink" & "Manila Paper" & "Envelop" & "Folder" & "Pencil"
            RBservices.Checked = False
        Else : RBservices.Checked = True
            Content = "Binding" & "Encoding" & "Photocopy" & "Print" & "Scan"
            RBproducts.Checked = False
        End If

        Dim sql As MySqlCommand = New MySqlCommand("Select DATE_FORMAT(Date, '%m/%Y') as Month, ServicesOrProduct, sum(Quantity) as Quantity, sum(Total) as Total from sales where Year(Date) = '" & cbYear.Text & "' and ServicesOrProduct = '" & Content & "' group by ServicesOrProduct, Month(Date) ORDER BY Month(Date)", con)
        Dim ds As DataSet = New DataSet()
        Dim da As MySqlDataAdapter = New MySqlDataAdapter()
        con.Open()
        da.SelectCommand = sql;
        da.Fill(ds, "sales")
        DGVYearly.DataSource = ds
        DGVYearly.DataMember = "sales"
        con.Close()
    End Sub
