Web Forms :: Error In Web Form / After Click "submit Button"
Sep 14, 2010
when i click "submit button" on my page it's show this error..where is the problem actually?
"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."

I need to collect the data entered by user for a quote and send all the data with labels to an email address. SMTP server is set up in web.config file, but I need to know the code behind for the submit button click event for the form. I do not need to store any data in a data base just need to send each label,field,radiobutton,etc. user responses to email address. All of the code I have been able to find has not applied to my situation.

I have a form as
<form action="" method="post">
<input name="Descripcion" type="hidden" value="" id="Descripcion" runat="server" />
<input id="Submit1" type="submit" value="Comprar" />
Instead of clicking on submit button i want that the form should be posted without clicking submit button with hidden fields

As the title says when I click the submit button on my form, instead of taking me to the next form with a url of controller/action/id or /action/id I am getting a nice 404 with a url of /id/action
The offending action is called IntakePage2. Typing the correct route manually works.
My routes are as follows:
[Code]....
The relevant controller code is as follows:
[Code]....
The partial that IntakePage1 loads:
[Code]....
<%}%>
IntakePage2 main page (The partial it references just has the text "boo" in it at the moment. It is intended to take an InsertViewModel object at some point.)
[Code]....

I have a form that works just fine, problem is that if user leave form open for more than 20 30 min and then click a button on that form the browsers status line shows "Error in page", user then must refresh the page in order for the page function.

I've been trying to figure this out all afternoon but my google-fu seems to be failing me. I'm setting up a page with a fairly large form, which has one field that is going to require some kind of popup page that will allow the user to perform a lookup.
At the moment I'm only prototyping the page so I'm actually only attempting to a the button up to fire an alert when the button is clicked instead of generating a lookup screen. However it seems that no matter what I do the button causes the form to submit.
I remember one of the very first ASP .NET beginner videos I ever watched went through configuring a button to perform actions without submitting, but I can't seem to figure out which one it was.

I have a web based form which is used to enter info into an Access DB. When a user clicks on the submit button in the form the information entered in the form goes into the DB. I have made the connection between aspx form and Access DB through an asp page using ADO.net.I wanted to add another feature into the form where when the user clicks the submit button a preformattedxcel sheet pops up with all the info filled onto it automatically (from the form). The user just need to save the file later on.

I am creating a webform that will be used for capture data. Whenever a certain option is selected in a drop down box, a textbox will appear for the user to type additional info into it.
However the problem that I am having is that it requires the user to click the submit button twice. I can't figure out how to fix this. The user should only have to click submit one time. All of the other drop down boxes work fine, it is just this one THAT IS forcing a click twice
Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="IT_EmployeeIncentive_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I was given this sample code from a financial institution to take a credit card payment:
Code:
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Insert title here</title>
</head><body>
<form method="post" action="<% Response.Write(ConfigurationSettings.AppSettings["BaseUrl"] + "MakePayment"); %>">
<input type="hidden" name="biller_code" value="123456" />
[Code] ....
But the problem is, that i need to put this into a VB.Net aspx page. And so the way here of doing a form/submit button won't work.
How do I put the code above into an aspx page written in VB.Net?

I need to implement a click-once button for my asp.net mvc 2 application. I have just a very simple submit form, and when the user clicks on the submit button, I need to change its image to a type of graphics and disables the click event for further submits until the server comes back.
Is there an example or code snippet for this?

i have a web form in which i ve a button which will open a sliding pop up box(jquery) on click of it. In the same page i ve also a linkbutton for downloading files. Now the problem is first time wen i click that button it does nothing. (will not open popup box). Once i click on download button and then if i click that button it will open popup box along with download dialog box. Why is it happening so... is it because am using same event click for both these.
but download option is implemented in gridview_rowcommand()..
