Unable to get a control value in ashx
Question
I am using uploadify to upload a file. By following this tutorial:
Problem is that although I am able to get file on ASHX using
HttpPostedFile postedFile = context.Request.Files["Filedata"];
I am unable to get value of a input box on the same form:
string str = HttpContext.Current.Request.Form["Name"];
ASPX form
<body>
<form id="form1" runat="server" >
<a href="javascript:$('#<%=FileUpload1.ClientID%>').fileUploadStart()">Start Upload</a>
| <a href="javascript:$('#<%=FileUpload1.ClientID%>').fileUploadClearQueue()">Clear</a>
<div style = "padding:40px">
<asp:FileUpload ID="FileUpload1" runat="server" />
</div>
<asp:TextBox MaxLength="100" CssClass="txtbox" Width="300px" ID="txtImgRemark" runat="server"> </asp:TextBox>
<input type="Text" name="password" id="password" value="0" />
</form>
</body>
</html>
<script type = "text/javascript">
$(window).load(
function() {
$("#<%=FileUpload1.ClientID%>").fileUpload({
'uploader': 'scripts/uploader.swf',
'cancelImg': 'images/cancel.png',
'buttonText': 'Browse Files',
'script': 'Upload.ashx',
'folder': 'uploads',
'fileDesc': 'Image Files',
'fileExt': '*.jpg;*.jpeg;*.gif;*.png',
'formData': { 'Name': 'arbaaz', 'Num': 1 },
'multi': true,
'auto': false
});
}
);
</script>
ASHX
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
context.Response.Expires = -1;
try
{
HttpPostedFile postedFile = context.Request.Files["Filedata"];
string str = HttpContext.Current.Request.Form["password"];
string savepath = "";
//blah blah blah

You need to add another parameter formData in the fileUpoad() function during the call like below.
$(window).load(
function() {
$("#<%=FileUpload1.ClientID%>").fileUpload({
'uploader': 'scripts/uploader.swf',
'formData': {'someKey' : 'someValue', 'someOtherKey' : 1},
'cancelImg': 'images/cancel.png',
'buttonText': 'Browse Files',
'script': 'Upload.ashx',
'folder': 'uploads',
'fileDesc': 'Image Files',
'fileExt': '*.jpg;*.jpeg;*.gif;*.png',
'multi': true,
'auto': false
});
}
);
On server side
string value= context.Request["someKey"];

I had the same problem where context.Request["Name"] gave null. This was because the HTTP post request contained a querystring AND form-data. It can't have both.
