Hi guys,
The codes below is running perfectly fine.
But I have a problem - if there are no records found in the database, my dropdownlist will not display nothing.
However, I want it to display something like "no records found" instead of havng it blank
Can someone tell me where should I place it to get the results i wanted?
Here are my codes.
InvoiceFunctions.class
Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Configuration
Public Class InvoiceFunctions
Private strConnectionString As String
Private objDataAdapter As SqlDataAdapter
Private objInsertCommand As SqlCommand
Private objLoadCommand As SqlCommand
Private objUpdateCommand As SqlCommand
Private objValidCommand As SqlCommand
Private objDeleteCommand As SqlCommand
Public Sub New()
MyBase.New()
objDataAdapter = New SqlDataAdapter
strConnectionString = ConfigurationManager.ConnectionStrings("Echino").C onnectionString
End Sub
Public Function GetInvoice() As DataSet
Dim query As String = "select * from Invoice"
Dim cmd As New SqlCommand(query)
Return FillDataSet(cmd, "invoice")
End Function
Private Function FillDataSet(ByVal cmd As SqlCommand, ByVal tableName As String) As DataSet
Dim con As New SqlConnection(strConnectionString)
cmd.Connection = con
Dim adapter As New SqlDataAdapter(cmd)
Dim ds As New DataSet()
Try
con.Open()
adapter.Fill(ds, tableName)
Catch ex As Exception
Finally
con.Close()
End Try
Return ds
End Function
Imports [Class]
Imports System.Configuration
Imports System.Data.SqlClient
Partial Public Class AddJobOrder
Inherits System.Web.UI.Page
Dim inv As New InvoiceFunctions
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If IsPostBack = False Then
ddl_Invoice.DataSource = inv.GetInvoice
ddl_Invoice.DataTextField = "invoiceNo"
ddl_Invoice.DataValueField = "invoiceNo"
ddl_Invoice.DataBind()
End if
End Sub
End Class
