Is there anothery of sorting a datagrid column for faster results? if so please kindly give guidance.

Presently the sorting is taking so long since it would need to requrey fro mthe sql server.


         Sub Sort_Grid(sender As Object, e As DataGridSortCommandEventArgs)
         Dim SortExpression As String
         SortExpression = e.SortExpression.ToString()
         If SortMode = "Desc" Then
         SortMode = "Asc"
         SortExpression = SortExpression + " " + "Desc"
         SortMode = "Desc"
         End If
         Dim odataView as DataView = GenerateSource().DefaultView
         End Sub 'Sort_Grid

    Private Function GenerateSource() As DataTable
    Dim con As New SqlConnection("Server=.....")
    Dim cmd As SqlCommand = con.CreateCommand()
    cmd.CommandType = CommandType.StoredProcedure
    cmd.CommandText = "SP_operator_score_details_view"
    cmd.Parameters.Add(New SqlParameter("@RETURN_VALUE", SqlDbType.Int, 4, ParameterDirection.ReturnValue, False, CType(0, Byte), CType(0, Byte), "", DataRowVersion.Current, Nothing))
    cmd.Parameters.Add("@operatorid",SqlDbType.int).Value = ddloperatorid.selecteditem.text
    cmd.Parameters.Add("@weekstartdate",SqlDbType.datetime).Value = ddlweek.selecteditem.text
    cmd.Parameters.Add("@qamonitorid",SqlDbType.int).Value = varqamonitorid
    Dim da As New SqlDataAdapter(cmd)
    Dim ds As New DataSet()
    Return ds.Tables("DataSetName")
    End function
