Process on current page then post hidden val to next page

[aconybeare]

Hi,

I'm wanting to process a form on the current page then send some hidden values to the next page i.e user Id, current journal name, manuscript number etc.
At the moment I'm using response.redirect and putting them in the queryString but I don't want to expose the user id in the querystring, I also want to avoid using cookies and session variables to hold this data.

Does anyone know if this is possible? Is there a way to use response.redirect and post?

Cheers Al

How about submitting the form? document.forms[0].submit(); and make sure that the method of the form is post.

Mendhak,

Thanks for your reply, where would I put the -

document.forms[0].submit();

In my codebehind page after saveData returns ok?

And how do I tell it where to submit to?

[mendhak]

Instead of Response.Redirect, use Page.RegisterStartupScript to run that code when the page loads.

mendhak,

I'm sorry, but I'm having real trouble getting my head round this

Is it possible to change a forms action on the fly then resubmit it.

eg -
html

<form id="frmSubmit" method="post" runat="server">
	<asp:textbox id=myName text=allan runat=server/><br>
	<asp:button id=cmdSubmit text=Submit runat=server/>	
</form>

codebehind

Private Sub cmdSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSubmit.Click, cmdSubmit.Click
  frmSubmit.Action = "nextpage.aspx"
  frmSubmit.Submit()
End Sub

Right,

I think I'm getting there now but it's not ideal as I have 40+ controls to write out
It would be better if I could just redirect the original form

Private Sub cmdSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSubmit.Click, cmdSubmit.Click
' Do processing here then redirect including some hidden values
  Response.Write("<form name=""hiddenvals"" action=""submission.aspx?page=1a"" method=""POST"" >")
  Response.Write("<input type=""hidden"" name=""Var1"" value=""5"">")
  Response.Write("<input type=""hidden"" name=""Var2"" value=""test"" >")
  Response.Write("</form>")
 
  Response.Write("<script>")
  Response.Write("document.forms[0].submit(); ")
  Response.Write("</script>")
End Sub
