View 1 RepliesI have a page that is based on my master page. the code below
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="CaseAdmin.aspx.cs" Inherits="Prototype4.CaseAdmin" %>
<%@PreviousPageType VirtualPath="~/Account/Login.aspx"%>[code]....
when the page above loads, i have link buttons on the left and an empty maincontent area next to its right. what i want to do is display an entry form in the main content on click event of the link button on the left. the second form is as below.(form not based on master page).
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="OpenCase.aspx.cs" Inherits="Prototype4.EntryForms.OpenCase" %>
<%@PreviousPageType VirtualPath="~/CaseAdmin.aspx" %>[code]....
how do i perform this task and if i wanted to display a different form in place of the first one that appeared in the maincontent area, how do i go about it?
I have Master Page and ascx user controls in my application.
how would I use the Cross-Page technique using the @ PreviousPageType directive.
useful links or samples to achieve this.
I am trying to use the Page class that exposes a property named PreviousPage from my User Control.
I add cascading drop down in a place holder during page load. When i submit the entire form, i found out that my drop down list is reload and my selected value is not selected.
View 3 RepliesI want to be able to post my form data to another page based on the result of a validation done on server (and not via javascript). As an example, let's say the user captures a customer number and then captures the phone number of the customer on page A. When the user clicks on the submit button, the page posts back. Then, in the button click event, I need to check in the database if the customer number exists. If it exists, I need to post the data to page B so that user can input the next information. If it does not, I need to stay on the first page and show an error message telling the user that the customer does not exists.
I do not want to use Response.Redirect cause that would mean that page B would lose the form data coming from page A. I know about crosspage postbacks but that just turn the problem the other way around (if I post directly to page B, how do I get back to page A with the form data and show the error message?)...I know about Server.Transfer too but I would like to avoid that method because I know there are down sides to it too...I tried setting the button target URL to page B after validating from the database but it does not automatically redirect to Page B, it still shows up Page A and then if you click again on the button you are taken to page B. I know I could setup a javascript to automatically call the click on the button to post the page the second time automatically to the Page B but I don't like that method (if the user has slow internet, he sees the page twice and once the user is on page B, he can't use the back button cause he would be automatically redirected back to Page B because of the script).So, is there a way to change the request target after the button's click code has been handled???
I don't know it's even possible but I try to achieve to post data from one page to another using the second form.The problem is I need a form tag for the user interface containing callback panels etc. I want to put a second form with some hidden-field:
<form id="postForm" method="post" action="target.aspx">
<input type="hidden" id="id" />
</form>
I submit the form from javascript with jquery:
$("#id").val(id);
$("#postForm").submit();
Is there a way access the value of the hidden field on the target page?

Is there a way to force a non-secure form post to be secure? I understand there are ways to automatically resolve an http URL as an https URL but with form posts, is this type of redirection too late? Will the posted data have already gone through the wire as plain text?
View 3 RepliesI 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 just discovered that you can't do this in an .aspx page. Seems the page will just post to itself if you hit the submit button.What's the proper technique for achieving this in ASP.NET? There are a couple of hidden fields that pass parameters to the external URL.

View 1 Repliesi have a PayPal button, and i've been trying to add it to my site, but since my page is in a masterpage, and ovcourse, the form tag is editable only in masterpage, theres no way i could add the code inside the form tag, as so:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="K92PCJ9ULE8LC">

I am trying to create a static HTML page which has a <form> which posts to a 3rd-party ASP.NET website.

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.
I hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.

One issue with ASP.NET apps is that they periodically reload themselves, causing a long delay and possibly timeout for users who hit the site during that time.
This may not be a problem for small websites, but it can represent significant downtime for high-traffic sites, if users happen to get routed to node in the web farm that is restarting.
Can load balancers somehow "know" if an ASP.NET application domain on a specific server is restarting? Then, they can route traffic around this server until the application has completed restarting.
Currently, I have my load balancer ping a simple .aspx page on the site. If there is a delay or the page fails to load, the host is taken out of rotation. Is it possible to do a more targeted health check, perhaps at the IIS level rather than ASP.NET level?
i am using this way to bind ASP.NET GridView Without postback. i want to know what are the problems of this way? what are the alternative ways? here is my code :
<input id="btnLoadDIV" type="button" value="button" />
<div id="somediv">
</div>
<script>
$(document).ready(function () {
$("#btnLoadDIV").click(function (e) {
e.preventDefault();
var url;
url = "test.aspx?type=test1";
$("#somediv").load(url);
});
});
</script>
Test.aspx BehindCode Code :
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Request.QueryString("type") = "test1" Then
bindgrid()
End If
End Sub
Test.Aspx markup code :
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</form>
</body>

asp.net with vb. I thought this would be easy but have been reading for an hour and not found out how to simply repost a page where form data has been entered and return the page with some error messages about what was entered. I want to return the page with all input controls with the data just as the user entered them before submitting. the error messages are labels that were blank when the page is first loaded. preferably the page returns focused to the topmost error error message. if that can't be done I would populate some label at the top of the page with something to the effect that 'errors were found, scroll down to see the errors'
View 2 RepliesI have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.
View 5 RepliesI have a sample page called Redirect.aspx with following content;
<body onload="document.forms.container.submit()">
<form id="container" runat="server" method="post" name="container">
<input type="hidden" value="<%=Request["APP_ID"]%>" name="APP_ID" />
</form>
</body>
the Page_Load method is following:
protected void Page_Load(object sender, EventArgs e)
{
container.Action = Configuration.Instance.PageToRedirect;
}
To this Redirect.aspx page, I'm directed from some external page. In the request context, I have APP_ID key, which is passed from this external page. Next, I want to pass this APP_ID value using POST to some other page, which is defined in the configuration. Unfortunately, I'm getting such error while redirecting:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
I don't want to disable view state validation (<pages enableViewStateMac="false">) because this is not the "solution" I want to apply.
Besides I don't understand why I'm getting such an error. Can someone get me through this ? Is there any other way to automatically submit a form on Page_Load event ?
I have a modal popup which contains a listview with multiple rows containing multiple controls so the form takes around 6-7 seconds to load, which is fine. What I want to do is display a little animated gif whilst its loading. What I don't understand is from the Page_PreInIt to the Page_SaveStateComplete (which is the first lifecycle method to last i think) it's only a matter of milli seconds.
a) why is it taking so long to load?
b) hows best to show the gif whilst the page loads (if possible)
$('#div1').load(url, {
id1=ident1,
id2=ident2
}, function() {
// Foo
})
is doing a post instead of what I thought should be a get. Is there a way to make it a get?
