But i have large data in the form. So I can't use those. Can anyone best way to save form data between postbacks and redirect.

I have a website that serves all its pages using a single 404 page. it displays hotel profiles form business and depending on different profile levels offers more or less functionality and information.
Through the DB a masterpage is selected and usercontrols are applyed to that.
I have a contact page like this : 404.aspx > masterpage.Master > contact.ascx
My form action looks like this default.aspx?404%3bhttp%3a%2f%2fwww1.testsite.co.uk%3a80%2fcontactus
and when I click the button this where I send up with an error "Validation of viewstate MAC failed" error.
I have read stuff on these for 4 hours but still have no idea where to start.
Do I need to
Catch the form action URL (postback URL) in the baseclass and change it back to [URL] - If I do this are the form firled values still intact
Do i need to do something to change the form.action url before the page is built, if so is this done in the masterpage preinit event as this is what the form tag is
What I know works is that the usercontrol is aware of the postback, but not the form values.
I want to be able to add a 404 based contact us form on any one of 1000s of profiles and be able to catch the values. Idearly I would like to do this in the codebehind of the usercontrol as this keeps the code seperate
I am sure this must be possible and normally I can work stuff out, but here I am totally stuck. I am trying to do this in VB.
I used Ajax collapsible extenders (1 to 9) with formviews in each of them on a web form.
They are all collapsed by default. If the user enters data in collapsible 5 formview and submits data, the page refreshes back to the top of the page (where the collapsible 1 is positioned). I would like the focus to stay in the region the user is working (even after insert/submit operations). How can I do this.
I am interested in finding difference betwen AJAX postback(Partial Postback) & Standard Web Form Postback(Full Postback).
1) What is the size of data submitted back to Server in AJAX & standard Postback(All Input elements are sent to Server here)
2) what is the size of Data that comes back when using Ajax Postback.
3) what is the difference in event Life cycle in AJAX & NON AJAX Post back

I have a browser-like software application that logs in to my asp.net site through the login control. Depending on the user info used, the application gets redirected to a text file in the server. The content of the file is then displayed in the application.
The files are created using vb.net streamwriter createtext.
I can get the content of the file correctly the first time the application logs in to the website, but the the 2nd and succeeding attemps results in garbage data (different encoding maybe?). I didn't get this problem when I was hositng the asp.net site locally using (IIS 5.1) - the site is currently hosted using II 6 remotely. what could be wrong? Could it be because I don't log-out of the site?

and I'm trying to clear the dropdown lists and the text box but also still give the thankyouLabel.Text message back to the user to give them some idea that their data has been submitted. I know that with a response.redirect that you're doing a postback but what I'm wondering is if there's a better way to clear a form so I can give users a clear form and also my thankyouLabel.Text message.
I've got a gridview which contains a dropdownlist. I've got it binding to display the correct name, but when I go to update it (and it could be the dropdownlist field or any other the other fields), I get an error stating it can't update the row because
addr_cnt doesn't allow null fields. I've tried just about everything I can find to get it to keep the addr_cnt value, but nothing seems to be working. My code is below:
<asp:GridView id="gvLeader" runat="server" AutoGenerateColumns="False" datakeynames="ldr_id" DataSourceID="dsLeaders" GridLines="Vertical">

I have a bulk editable gridview. I want to find a way of keeping a running total up to 100 in each row when the user is entering values into the editable columns. I then want to save this data.
The running total column (Total) is a bound column and not editable by the user.
When you click the edit button in detailsview I want it to store some values in "PreviousAddress" and "PreviousVehicle" to show what the data used to be before it was edited... Just wondering what would be the best way of doing this?
View 5 RepliesI would like to save some data for use after a page postback. Here is an example of what I'd like to do:
Partial Class TestPage
Inherits System.Web.UI.Page
Private _CategoryID As String = ""
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
_CategoryID = "ABC"
Me.ViewState("CategoryID") = _CategoryID
Else
_CategoryID = CType(Me.ViewState("CategoryID"), String)
End If

I've tried both session variables and view state. The page loads fine initially, but on postback I get the following error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
What am I doing wrong? How can I save this data for use after postback?

View 1 RepliesAll of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns.

View 15 RepliesUsing Facebox with .NET (Web Forms) is painful--this primarily HTML site was designed by someone else. I may have IIS (7.5) issues as well. This Facebox pop-up is in a separate file, login.html, that is called from index.html:
$k('a[rel*=example_2]').facebox_1({
loading_image : '/images/loading.gif',
close_image : '/images/closelabel.gif'
});
and the link to open it
<a href="login.html" title="Log In" rel="example_2" id='login'>Log In </a>
The form to be submitted with username and password (login.html):
<form name="login" method="post" action="#" onsubmit="return false;">
and after it's validated (this is working), it posts to login.aspx (login.html):
[code]....
The form posts. I can debug it in Visual Studio in the Page_Load method of login.aspx. The last line of the Page_Load method is:
Response.Redirect("welcomepage.html");
But, the Facebox pop-up remains. Firebug shows the post, It hits the Page_Load method of login.aspx, and the Facebox pop-up doesn't go anywhere. BUT, Firebug shows welcomepage.html rendered twice in the Response tab of the XHR (huh? why XHR?) request. I thought $.post did a regular postback. And why isn't my browser actually redirecting.
Attempted Fix
If I change the form in login.html to action='login.aspx', I get a 405.0 error method not allowed (but, it's trying to post to index.html, HUH?). And I can't figure out how to fix this in IIS 7.5 on Windows 7. I get this error in Visual Studio and when deploying locally to IIS. I had read it may have to do with script mapping, handlers, or the fact that I'm posting from an but I can't find a sufficient fix.
I'm developing a web app for which the client wants us to query their data as little as possible. The data will be coming from a Microsoft CRM instance.
So we've agreed that data will only be queried as and when it is needed, therefore if a web user wants to see a list of contacts (for example) that list is fetched into a local DataTable. Then if a new contact is created on the website the new contact is sent to CRM and added to the local DataTable at the same time. Likewise for edits.
If the user then looks at their contacts again the data will just come from the local DataTable.

Currently whenever I need to send a request to a payment-gateway, for example, I redirect my page to another page on my website which has a form with several hidden fields. I then pre-populate the values of these fields server-side, and specify in the body tag something like 'onload="form.submit();"'
However, I'm wondering, rather than redirecting to this page, is there anyway that all this data can be collected and POSTed to the payment-gateway server-side?This will cut out the need to redirect the user to this blank page, and make everything a bit more tidy.
