How do I filter my DataGridView using a ComboBox selection?

I have an ADO.Net app that uses an ODBC connection to a remote database (so I don't need to hardcode in the servername and password). I have one form that uses a DataGridView to show data from a TableView. I need to filter this data using the selected item in a ComboBox. I'm using the SelectedIndexChange method. I can build everything down to the dataset but I cant get the DataGrid view to show any of the selected data. What am I doing wrong?

  Dim Con As New Odbc.OdbcConnection
        Con.ConnectionString = My.Settings.ODBCConnectionString
        Dim Com As New Odbc.OdbcCommand
        Com.Connection = Con
        Com.CommandText = "Select ProductName, CategoryName, Barcode, UnitsInStock, Par " & _
                          "From vProduct " & _
                          "Where ProductName like '" & ComboBox1.SelectedValue & "' and Discontinued = 0 " & _
                          "Order By ProductName"
        Con.Open()
        Dim da As New Odbc.OdbcDataAdapter
        Dim ds As New DataSet

        da.SelectCommand = Com
        da.Fill(ds, "Product")
        VProductDataGridView.DataSource = ds
        VProductDataGridView.DataMember = "Product"

Thanks
