How do i print a value in my markup from the code behind file

Question

I have this code in my markup:

<form id="myfileupload" action="/_layouts/IrvineCompany.SharePoint.CLM/aspx/Upload.ashx?ProjectApprovalId=" method="post" enctype="multipart/form-data">

If you look at the url in the action property:

/_layouts/IrvineCompany.SharePoint.CLM/aspx/Upload.ashx?ProjectApprovalId=

I want to be able to add a number at the end of ProjectApprovalId from a variable in the codebehind file. How can i accomplish this?

Answer 1

Can you try:

/_layouts/IrvineCompany.SharePoint.CLM/aspx/Upload.ashx?ProjectApprovalId= <%=VariableName%>

Answer 2

From an ASP.NET point of view you will have to make the form object a server-side object to access it in codebehind.

like

 <form runat="server" id="form1">

Answer 3

Depending on your needs, you can post the form to itself and then, in code-behind, do:

...
Response.Redirect ("/_layouts/IrvineCompany.SharePoint.CLM/aspx/Upload.ashx?ProjectApprovalId=" + yourVariableName);
...

It will redirect to the handler and you can pass whatever you want as QueryString
