PostBackURL

[sck10]

Hello,

Can you use the PostBackUrl to post to different sites? I have a page
(PostBackURL.aspx' ) on one website (same server) that has a button set to:

PostBackURL="http://zone1.web.com"

When the second page opened, and tried to get a hidden value on the previous
page, I got the following error:

The file '/xaspx/zTest/PostBackURL.aspx' does not exist.

this.hdnQV01.Value =
((HiddenField)PreviousPage.FindControl("hdnCourse")).Value;

Any help with this would be appreciated.

Thanks, sck10

From the MSDN:
--------
If the source and target page are in different applications, you cannot
directly get the values of controls on the page, but you can read the posted
data from the Form dictionary. You cannot read view state from the source
page, because it is hashed. If you want to store values in the source page
and make them available in a target page in another application, you can
store the values as strings inside hidden fields on the source page and
access them through Request.Form on the target page.

Hello Steve,

From your description, what you want to do is post data from one of your
ASP.NET application to another ASP.NET application hosted on a remote
server, correct?

Based on the code snippet you provided, it seems you're using the cross
page posting in ASP.NET 2.0 for pages in separate web application(server)
,yes ? If so, I'm afraid this is not supported, crosspage posting can only
be used in pages within the same ASP.NET web application. For your
scenario, if you have an html input hidden field in the source page(who
send the post to target page), you can use its "name" to retrieve its value
from the Request.Form collection. e.g.

=====in target page=========

protected void Page_Load(object sender, EventArgs e)
{

string value = Request.Form["hdnCourse"];
....................

}
==================

Does this work for you? Please feel free to let me know if there is any
other concern here.

Sincerely,

Steven Cheng

So try the Request.Form.
