[Asp.Net]Cross-Page Posting

使用post做網頁間 表單傳送資料。

例：A網頁 -->B網頁

  

A.aspx

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="A.aspx.vb" Inherits="A" %> .....           ..... .....

B.aspx.vb 

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load         If Page.PreviousPage IsNot Nothing Then             Dim textValue as String = Ctype(PreviousPage.FindControl("TextBox1"),TextBox).Text         End If End Sub

2.送出按鈕做了前端 (javascript)及後端Button.Click的檢查後將表單傳送至下一頁的做法。

  

例：A網頁(含檢核)-->B網頁

  

A.aspx

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="A.aspx.vb" Inherits="A" %> ..... ..... <form id="frm" name="frm" runat="server">  <asp:TextBox ID="TextBox1" runat="server" />  <asp:Button ID="Button1" runat="server" PostBackUrl = "B.aspx"/>      .....      .....

A.aspx.vb

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click     If XXXXX Then             .........             '傳送至下一頁             RegisterStartupScript("Page", "")     Else             '顯示錯誤訊息             RegisterStartupScript("Page", "")     End If End Sub

B.aspx.vb 

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load         If Page.PreviousPage IsNot Nothing Then             Dim textValue as Stringn = Ctype(PreviousPage.FindControl("TextBox1"),TextBox).Value         End If End Sub
