How to send Request.Form

I'm doing something really bad with my code. I'm getting all data posted to the actual page and putting into html inputs:
private void GetPostedForm()
{
System.Text.StringBuilder displayValues = new System.Text.StringBuilder();
System.Collections.Specialized.NameValueCollection postedValues = Request.Form;
for (int i = 0; i < postedValues.AllKeys.Length; i++)
{
String nextKey = postedValues.AllKeys[i];
if (nextKey.Substring( 0, 2 ) != "__")
{
displayValues.Append( "<input type='hidden' name='" + nextKey + "' value='" + postedValues[i] + "'/>" );
}
}
hiddensPost.InnerHtml = displayValues.ToString();
}
But the html inputs in this page are useless to me. I'm putting a page between 2 older pages ("A" sent form to "B"). Now I need to send "A" to "X" and then send to "B".
The question is: How can I put the requested form into the actual form to send to the next page without doing all this mess in HTML?

You can put your steps(A,X,B) and it's visible inputs, into separate asp-panels(pnlA,pnlX,pnlB)
then simply toggle panels visibility in which state you want.the ViewState will do it for you (store controls states into one hidden field within the form to post again with inputs)
so you may post user entered data 3 times with one html form( the famous asp.net form)
another solution is here , the asp.net wizard control

If you can, just change the method to GET and pass the QueryString along from page to page.

Setting window.location on a LinkButton's onClientClick from code behind

Can't be this hard can it!? I just want to change window.location onclientclick of a linkbutton and set this from code behind.
lb.OnClientClick = "window.location = 'Contact.aspx'";
Not working, just reloads the current page.
lb.OnClientClick = "window.location = '" + Server.MapPath("Contact.aspx") + "'";
Seems to resolve the url correctly (the dev folder on my C drive) but is denying me access!?

Example of how to use dynamically:
if (status = "fun")
HttpServerUtility.Transfer("fun.aspx");
else
HttpServerUtility.Transfer("sad.aspx");
also this should work
lb.OnClientClick = "window.location = 'Contact.aspx'; return false;"
Original post:
If it is in the code behind just use Transfer
HttpServerUtility.Transfer("Contact.aspx");
and this will pass all the form information:
HttpServerUtility.Transfer("Contact.aspx",true);
MS also has good documentation on all your options here

Not getting Id in Mozilla Firefox

C#
HtmlButton btnSave = new HtmlButton();
btnSave.ID = "btnSave" + i.ToString();
btnSave.Attributes.Add("onClick", "javascript:return SubmitSave(" + btnSave.ID + ");");
javascript
function save(e)
{
var getId=e.id;
}
I am not getting id in Mozilla firefox,bout its working fine in IE

You can pass the Client ID instead of the ID btnSave.ClientID as ClientID is the perfect choice to deal with such a situation.
btnSave.Attributes.Add("onClick", "javascript:return SubmitSave(" + btnSave.ClientID + ");");
function save(e)
{
var getId=e; // Now you have Client ID, you can use directly instead getting through e.id
}

That is because you are using the id as a variable. Some browsers add the id:s as properties in the window object so that you can access them directly, but to make it work in anything but those few browsers you should use the getElementByID method to locate the element.
btnSave.Attributes.Add("onClick", "javascript:return SubmitSave(document.getElementByID('" + btnSave.ID + "'));");

YUI AJAX and .Net MVC

I'm having a bit of an issue with a mix between YUI's AJAX and a YUI Datatable. The AJAX request fires properly and I get back the correct data formatted as:
{NoteId:'" + result.NoteId + "', CreatedOn:'" + result.CreatedOn.ToShortDateString() +
"', UpdatedOn:'" + result.UpdatedOn.ToShortDateString() + "', CreatedBy:'" + result.CreatedBy +
"', NoteContent:'" + result.NoteContent + "'}
These match the table identities properly, and I ripped this formatting from the statement that initially creates the datatable (which works properly). I don't know if I have the 'onSuccess' messed up for my AJAX call or what, and this is my first time touching YUI.
Also, if I manually execute the noteTable.addRow and hard code the data, it works.
Code for the AJAX call and Table Update:
function addNote() {
var noteText = editor.get('element').value;
var id = '<%= Model.Menu.Level1Tab %>'
var lpqId = <%= Model.LpqID %>
var sUrl = "/Lpm/Notes";
var callback = {
success: function(o) {
noteTable.addRow(o.responseText);
},
failure: function(o) {
}
}
var transaction = YAHOO.util.Connect.asyncRequest('POST', sUrl, callback, 'id=' + id + '&noteContent=' + noteText + '&noteId=' + noteId + '&lpqId=' + lpqId);
}
I'm pretty well stuck on this, so if anyone could have a look and let me know where I messed something up, I'd appreciate it. If you need more info, I have plenty, including firebug debugging info.
Thanks in advance for the help

Looks like you need to convert the o.responseText from string to object. The JSON Utility can help you do that: http://developer.yahoo.com/yui/json/.
Incidentally, DataTable's DataSource integration can help manage these issues for you. This example (http://developer.yahoo.com/yui/examples/datatable/dt_xhrjson.html) shows you how to set up a DataSource and integrate it with a DataTable. Note how you can send a request to get some data from your server and then use one of the "onDataReturn..." methods (see "Loading data at runtime" under http://developer.yahoo.com/yui/datatable/#data) in your callback.

Getting the executed output of an aspx page after a short delay

I have an aspx page which has some javascript code like
<script>
setTimeout("document.write('" + place.address + "');",1);
</script>
As it is clear from the code it will going to write something on the page after a very short delay of 1 ms. I have created an another page to get the page executed by some query string and get its output. The problem is
I can not avoid the delay as simply writing document.write(place.address); will not print anything as it takes a little time to get values so if I set it in setTimeout for delayed output of 1 ms it always return me a value
If I request the output from another page using
System.Net.WebClient wc = new System.Net.WebClient();
System.IO.StreamReader sr = new System.IO.StreamReader(wc.OpenRead("http://localhost:4859/Default.aspx?lat=" + lat + "&lng=" + lng));
string strData = sr.ReadToEnd();
I get the source code of the document instead of the desired output.
I would like to either avoid that delay or else delayed the client request output so that I get a desired value not the source code.
The JS on default.aspx is
<script type="text/javascript">
var geocoder;
var address;
function initialize() {
geocoder = new GClientGeocoder();
var qs=new Querystring();
if(qs.get("lat") && qs.get("lng"))
{
geocoder.getLocations(new GLatLng(qs.get("lat"),qs.get("lng")),showAddress);
}
else
{
document.write("Invalid Access Or Not valid lat long is provided.");
}
}
function getAddress(overlay, latlng) {
if (latlng != null) {
address = latlng;
geocoder.getLocations(latlng, showAddress);
}
}
function showAddress(r) {
place = r.Placemark[0];
setTimeout("document.write('" + place.address + "');",1);
//document.write(place.address);
}
</script>
and the code on requestClient.aspx is as
System.Net.WebClient wc = new System.Net.WebClient();
System.IO.StreamReader sr = new System.IO.StreamReader(wc.OpenRead("http://localhost:4859/Default.aspx?lat=" + lat + "&lng=" + lng));
string strData = sr.ReadToEnd();

I'm not a JavaScript expert, but I believe using document.write after the page has finished loading is a bad thing. You should be creating an html element that your JavaScript can manipulate, once the calculation is complete.
Elaboration
In your page markup, create a placeholder for where you want the address to appear:
<p id="address">Placeholder For Address</p>
In your JavaScript function, update that placeholder:
function showAddress(r) {
place = r.Placemark[0];
setTimeout("document.getElementById('address').innerHTML = '" + place.address + "';",1);
}

string strData = sr.ReadToEnd();
I get the source code of the document instead of the desired output
(Could you give a sample of the output. I don't think I've seen a web scraper work that way so that would help me to be sure. But if not this is a good example web scraper)
Exactly what are you doing with the string "strData" If you are just writing it out, I recommend you putting it in a Server side control (like a literal). If at all possible, I'd recommend you do this server side using .net rather than waiting 1 ms in javascript (which isn't ideal considering the possibility that 1 ms may or may not be an ideal amount of time to wait on a particular user's machine hence: "client side"). In a case like this and I had to do it client side I would use the element.onload event to determine if a page has finished loading.
