Question

Answer 1

+1 A:

Change "button" to "submit"

<body>
  <form id="UploadForm" method="post"  enctype="multipart/form-data" action="http://localhost:2518/Web/CrossPage.aspx"&gt;
    <div>
      <input type="file" id="BtnUpload" />
      <input type="submit" id="BtnSubmit"  value="Submit" />
    </div>
  </form>
</body>

To your <asp:button>you have not just the Text but also the runat attribute right?

These w3schools pages may help you

Thanks Dan. When i try to use <asp:Button> the page doesn't post so what could be the reason for that too

Added a new bit about the asp:button control and another link for you.

Dan McGrath 2010-06-10 11:02:09

No, the asp:button doesn't post the page to given URL.

Sri Kumar 2010-06-10 11:05:58

Can you post your actual asp.net code then?

Answer 2

+1 A:

If you are using the asp:button control in ASP.NET you might want to add the runat="server" to your "form".

<form runat="server" id="UploadForm" method="post"  enctype="multipart/form-data" action="http://localhost:2518/Web/CrossPage.aspx"&gt;

Also if you do not want to implement the server side event handler for submit, you can use the onclientclick="submit".

<body>
<form id="UploadForm" method="post"  enctype="multipart/form-data" action="http://localhost:2518/Web/CrossPage.aspx" runat="server">
<div>
<input type="file" id="BtnUpload" />
<asp:Button Text="Submit" runat="server" onclientclick="Submit" />
</div>
</form>
</body>

This works for me.

I copied the code and pasted it. But it doesn't work for me :(

Sri Kumar 2010-06-10 11:33:59

OK, What is the error you receive? Also, what version of ASP.NET are you using?

Preets 2010-06-10 11:37:57

I don't receive any error. 3.5 is my version

Sri Kumar 2010-06-10 11:44:13

Could you please you post the aspx and aspx.cs code for your form?

Preets 2010-06-10 11:53:23

Did you create the forms from scratch, or did VS create the forms for you? I can suggest adding a new web form and then pasting this code in the <body> section of the aspx.

Sri Kumar 2010-06-12 06:50:54

i don't have c# coding.

Sri Kumar 2010-06-12 06:51:25

Sri Kumar, I tested the code you have pasted and it worked for me. That is, when I clicked the Submit button it redirected me to http://localhost:2518/Web/CrossPage.aspx (Obviously, since the file CrossPage.aspx does not exist on my machine, I get an error, but the redirection works fine)

Preets 2010-06-18 08:25:29

Thanks :) I changed the whole logic to post the file. Now I am using HttpWebRequest

Sri Kumar 2010-06-18 08:56:36

Sri Kumar, good to know you got it working :)
