ผิดตรงเมื่อเกิด event page load เจ้า count จะถูก set ให้เป็น 1 ทุกครั้งไง
กด next มันเลยได้อีก +1 เลยเท่ากับ 2
Code (VB.NET)
<%@ Import Namespace="System.Data"%>
<%@ Import Namespace="System.Data.SqlClient"%>
<%@Import Namespace="System.IO" %>
<%@ Page Language="VB" %>
<script runat="server">
Private Dim count As Integer
Sub Page_Load(sender As Object, e As EventArgs)Handles Me.Load
If Request.QueryString("page") Is Nothing Then
count = 1
Else
count = CInt(Request.QueryString("page").ToString())
End If
state.Text = count.ToString()
Select Case count
Case 1
button1.Visible = False
button2.Visible = True
Me.pnlAdd1.Visible = True
Me.pnlAdd2.Visible = False
Me.pnlAdd3.Visible = False
Me.pnlAdd4.Visible = False
Case 2
button1.Visible = True
button2.Visible = True
Me.pnlAdd2.Visible = True
Me.pnlAdd1.Visible = False
Me.pnlAdd3.Visible = False
Me.pnlAdd4.Visible = False
Case 3
button1.Visible = True
button2.Visible = True
Me.pnlAdd3.Visible = True
Me.pnlAdd2.Visible = False
Me.pnlAdd1.Visible = False
Me.pnlAdd4.Visible = False
Case Else
button1.Visible = True
button2.Visible = False
Me.pnlAdd4.Visible = True
Me.pnlAdd2.Visible = False
Me.pnlAdd3.Visible = False
Me.pnlAdd1.Visible = False
End Select
End Sub
Sub btnPrevious(sender As Object, e As EventArgs)
count = count - 1
If count < 1 Then
count = 1
End If
Response.Redirect("ชื่อไฟล์.aspx?page=" & count.ToString())
End Sub
Sub btnNext(sender As Object, e As EventArgs)
count = count + 1
If count > 4 Then
count = 4
End If
Response.Redirect("ชื่อไฟล์.aspx?page=" & count.ToString())
End Sub
</script>
<form runat="server">
