c# - Post ASP.Net Form data to another page

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

I have an ASP.Net Page, aspx with its default form.

I have a Submit Button for it. Upon clicking, it will post the data to itself. In other words, Button Click Event() from code behind will execute the necessary.

After that, I would like to post the same data to another ASp.Net Page, aspx from another domain.

So, how can I do it?

I tried creating a Form in Button Click Event and a javascript to Submit the Form so that it will post. But the Form is not appearing hence there is already aForm` on the page.

Is there anyway to do it?

Use the Button's PostBackUrl property. http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.button.postbackurl.aspx

<%@ page language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="head1" runat="server">
  <title>Button.PostBackUrl Example</title>
</head>
<body>    
  <form id="form1" runat="server">

    <h3>Button.PostBackUrl Example</h3>

    Enter a value to post:
    <asp:textbox id="TextBox1" 
      runat="Server">
    </asp:textbox>

    <br /><br />

    <asp:button id="Button1" 
      text="Post back to this page"
      runat="Server">
    </asp:button>

    <br /><br />

    <asp:button id="Button2"
      text="Post value to another page" 
      postbackurl="Button.PostBackUrlPage2cs.aspx" 
      runat="Server">
    </asp:button>

  </form>
</body>
</html>
