Web Forms :: Forcing Postback Of IFrame Form
Jan 6, 2010
I'm trying to solve a problem and am open to any suggestions. Here's the situation:
I have a checkout page that has an iFrame that contains a credit card form. The credit card form resides on an external site that is PCI compliant (and it is a requirement that we are PCI compliant so having the credit card form on our domain is not an option). When the user submits the checkout form, I need a way to force the submission of the iFrame form on the server side. This is because I need to wait for the credit card form's site to send back a reply via a web service on my end, which will be passing a token that I save and use later on when the order is submitted. I also will display any validation errors that are reported from the credit card form site, also via the web service.
This all worked just fine in a simulation, but I'm getting permission errors trying to access the form in the iFrame across domains (and after researching this, apparently it's not possible to access an iFrame's document across domains). I need a way to force the submit of the iFrame form on the server side without having access to the form itself. Can this be done? Can anyone suggest an alternative to what I'm trying to accomplish?

Please take a look at the following click event...
Protected Sub btnDownloadEmpl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDownloadEmpl.Click
Dim emplTable As DataTable = SiteAccess.DownloadEmployee_H()
Dim d As String = Format(Date.Now, "d")
Dim ad() As String = d.Split("/")
Dim fd As String = ad(0) & ad(1)
Dim fn As String = "E_" & fd & ".csv"
Response.ContentType = "text/csv"
Response.AddHeader("Content-Disposition", "attachment; filename=" & fn)
CreateCSVFile(emplTable, Response.Output)
Response.Flush()
Response.End()
lblEmpl.Visible = True
End Sub
This code simply exports data from a datatable to a csv file. The problem here is lblEmpl.Visible=true never gets hit because this code doesnt cause a postback to the server. Even if I put the line of code lblEmpl.Visible=true at the top of the click event the line executes fine, but the page is never updated. How can I fix this?

I have been trying to figure out out to force a postback from an asp ajax extender. The closest post that I can find is
http://forums.asp.net/t/984558.aspx
However I am pretty sure this was at least one migration ago. Additionally I am using VB as my programming language so some of the conversion may be the problem.
I think I am pretty clear on what needs to be done.
If I am correct the steps are...
Create a new property in the extender to hold the postback command for each target control that is using the extender.
Then in the Onload populate that property (Use GetPostBackEventReference to get the ASP valid target ID ) so it can be called from the Clientbehavior.js
My problem is the syntax in the for-each loop that allows me to iterate through the target controls.
Protected Overloads Overrides Sub OnLoad(ByVal e As System.EventArgs)

I have basically the following structure set up :
[Code]....
I am aware that a FileUpload requires a full page postback. I read the article http://www.4guysfromrolla.com/articles/090209-1.aspx[^]I tried to install a PostBackTrigger programmatically to get a full postback only on the ImageButton1 control. All other postbacks must be partial. (GridView sorting, paging, ...)In code behind I do :
[Code]....
The above code does not seem to install a full postback only for the ImageButton1, so the file upload fails. How can I make this work ?

Hoping I have placed my question in the correct forum.
I am writing an application that simply updates a text box (contained in a AJAX UpdatePanel) via a thread. the eventual idea being that the textbox will be placed in the master page, and a thread will poll a table to check for status messages. 90% of the code works as it should, the only side that is not working, is physically updating the textbox. The value of the textbox is being updated, but it is not being reflected on the screen. When the text is updated in the textbox, the OnChange event is not firing (as it shouldn't), but I still need the textbox to be updated. The textbox is being updated prgramatically, and not by the user.
When the thread triggers, it just fires an event, which right now just updates the textbox with the current date time. I've tried a million and one different ways, but still no luck :( Anyone know where I am going wrong?
Here is my code:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Always" runat="server">
<ContentTemplate>
<asp:Table ID="Table1" runat="server">
<asp:TableRow>
<asp:TableCell>
<asp:Label ID="lblThread1" runat="server" Text="Thread1"></asp:Label>
</asp:TableCell>
<asp:TableCell>
<asp:TextBox ID="txtThread1" AutoPostBack="true" runat="server"></asp:TextBox>
</asp:TableCell>
<asp:TableCell>
<asp:Button ID="btnstartThread1" runat="server" Text="Start Thread 1" onclick="btnstartThread1_Click" />
</asp:TableCell>
<asp:TableCell>
<asp:Button ID="btnStopThread1" runat="server" Text="Stop Thread 1" onclick="btnStopThread1_Click" />
</asp:TableCell>
</asp:TableRow>
</asp:Table>
</ContentTemplate>
</asp:UpdatePanel>
public partial class _Default : System.Web.UI.Page
{
private static clsThread1 _objObject1 = new clsThread1();
private static Thread _objThread1;
//****************************************
protected void Page_Load(object sender, EventArgs e)

{
_objObject1.UpdateThread1Time += new EventHandler(UpdateThread1TimeEvent);

}

}

{
_objThread1 = new Thread(new ThreadStart(_objObject1.StartProcess));
_objThread1.Start();
while (!_objThread1.IsAlive) ;
}
//****************************************

if (_objThread1 != null)
{
_objThread1.Abort();
_objThread1.Join();
}
}

I have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.
1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice
2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.

I'm using iframe for integration of ASP.Net application somehow one of the page closes iframe window and opens in the new window. I went through the code and noticed that postback is occuring two times for this page and it is leaving the control. This page uses UserControl and if I remove the UserControl then it works fine.
<iframe
src
="http://localhost/Portal/V5/Accounts/AccountList.aspx"
height="550px"
width
="950px"
runat
="server"
scrolling="auto"
></iframe>

This post is related to the issue of using javascript with asp.net form found here:[URL]I figured out that the issue I am having is not that the javascript cannot find the control but rather that the ajax frame I am using, for some reason does not allow me to find the controls.Here is how I submit my form in VS 2008 which is working fine:
<form id="form1" runat="server" target="ajaxFrame" defaultfocus="userName">
The ajax frame below, is on the login page right before the body closing tag:
<iframe id="ajaxFrame" name="ajaxFrame" src="" style="visibility:hidden;"></iframe>
When the user clicks the login button, all the vb.net code on the code behind page is executed and some hidden fields are populated with some login/user validation data. The iframe then takes the user name and password (using jquery and some custom javascript) and automatically redirects and login the user on another website where an asp/js login page is used.For some reason, this exact setup does not work with asp.net 4.0.

I have a aspx page, in that page i have an Iframe. In the Iframe i do some stuff in code behind and when it is done I would like to do a postback from the aspx. In other words, Is it possible to do a postback programatically from the code behind of the iframe to the parent page?I think a postback can be done using "ClientScript.GetPostBackClientHyperlink(New Control(), String.Empty)" but that will only do a postback for the iframe i think.

I have a page with a ScriptManager / UpdatePanel. I currently need to PostBack to a https page from an http page (different ports). I also need the same session data. Currently, I copy my form to a new form, and when I postback to my new Target on a new Port, I get a crash in xmlHttp..something. I will have to post more details later.
I'm currently wondering if this is possible. And does anyone know of such a fix. I even tried to Turn off Partial Rendering and I still get crashes. I can't do this until I pull out the scriptManager / UpdatePanel.

I need to know how to post information from an HTML <form> to a page that's within an IFRAME on an external server. In other words, the page with the <form> is on the first server, page being posted to is on the second server within an IFRAME which is also on the second server.
I've seen snippets of code for posting to a page within an IFRAME, but I believe that these apply to an IFRAME and target page on the same server as the posting page.

I have created a web application that docks other web applications into it.When an application is docked the app creates a link button in its "tool box" on the left hand side of the page, users can easily click on any link button to navigate to the desired docked app.
I have a web app that uses iframes to display other web applications inside it. In effect it is a docking application where users can easily access many web applications from within one main app, while staying within the main app. I am having challenges dynamically resizing the iframe based on the size of the application the user is accessing.I have searched the web and tried many ideas but have yet to discover the code that will do the trick.
First, for a docking web application is the iframe the best approach? I have see some posts on ajax but am uncertain how that will help.
Second, if an iframe is the way to do it does anyone have code that will completely liminate the need for iframe scroll bars?
Note:The applications docked in the main we app may be of any size and can change size as users interact with them.

Our website application needs to open other web sites Iframe.(Our application is web based tool to help high school children to analyze the websites. It has to show news websites to in one iframe and in rest of the page there will be questions related to the news website)
But since many websites use framekiller code, these sites take control of entire page. Is there any ternative way / solution to this problem?It is necessary to be able to open other sites in our website (in iframe or any alternate way), otherwise whole concept of our application will become void.

I have recently upgraded a .net 1 web application to .net 2.0. Everything works fine except some of the administrator pages. These pages load ok but on postback they give the following error:
Type 'WebModules.Accounts.Business.SiteIdentity' in assembly 'test20, Version=1.0.3777.35197, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
Stack Trace:
[Code]....
[SerializationException: Type 'WebModules.Accounts.Business.SiteIdentity' in assembly 'test20, Version=1.0.3777.35197, Culture=neutral, PublicKeyToken=null' is not marked as serializable.] Microsoft.VisualStudio.WebHost.Connection.ReadRequestBytes(Int32 maxBytes) +0 Microsoft.VisualStudio.WebHost.Request.ReadEntityBody(Byte[] buffer, Int32 size) +86 System.Web.HttpRequest.GetEntireRawContent() +8766749 System.Web.HttpRequest.GetMultipartContent() +62 System.Web.HttpRequest.FillInFormCollection() +168 System.Web.HttpRequest.get_Form() +68 System.Web.HttpRequest.get_HasForm() +8722023 System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull) +97 System.Web.UI.Page.DeterminePostBackMode() +63 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +133
This happens only on my local machine. On the remote server it works fine. The problem also happens before the Page_load method is called (I have tried to debug).This is definitely not a problem of my code; it must be a .Net problem. I have narrowed down the problem of a particular page to the data binding of a datagrid. If I comment it out, the page works (the datagrid contents are not displayed of course). I have found on msdn that one of their security fixes causes this problem to occur in .Net 2.0, but the fix is for Vista. I am running XP so there must be something similar to XP.

(Using ASP.Net 2.0 on Visual Studio 2005, coding in C#)I write in the hope that someone will be able to provide a clue as to how I might best overcome this issue:I've got a form with 2 RequiredFieldValidators, and 2 buttons. Button 1 has 'CausesValidation' set to 'False', and populates some of the other fields on the form from the database (via a postback).Button 2 fires the validation, then if the form is valid brings a javascript popup confirmation box and then, if true, it puts the data in the form into an email.All this is working fine. However......My problem is this: If I press button 2 with my required field(s) empty, the form quite correctly refuses to submit, and highlights the appropriate field(s) with a red *.But: if I then press button 1 (my populating button) it DOES NOT FIRE until I press it a second time!Code snippet follows (markup only - I will of course post code-behind if nec. but I don't think it is)
<script type="text/javascript">
function ConfirmSubmit()

I have a problem at the moment that I cannot figure out how to solve. I have an asp:Wizard control on my page, which contains a google map. Now, for google maps, you need to specify what html will be put into the info windows (the little bubble that comes up when a marker is clicked).
What I want is for my info window to have a 'Select and Continue' button in it, which would act the same way as if the user clicked the next button on the Wizard at that time.
So when I create the html for the info window, I have the following:-

However, the page just seems to reload, and the wizard doesn't move on to the next step.
