Heres the Controller:

Here is my Model:

By default Index, renders with an empty results set, on button press i want it to go to the "StartSearch" Action, and rerender the index with possibly non-null results set.

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 am facing a problem related to register routes.
private void RegisterRoutes(RouteCollection Routes) { Route myroute3 = new Route("{controller}", new MyRouteHandler()); Routes.Add(myroute3); }
Now, I intentionally made an error. asp.net not showing the appropriate error but "page not found" When I traced it: its is showing the following stack trace: [URL]
Source: System.Web Message: Error executing child request for Error.aspx. I am not been able to track errors.

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 have two asp.net applications webapp1 and webapp2, in each application i have a asp.net form Deafult.aspx
I want to do a form submit from Default.aspx in webapp1 and recieve the value in webapp2.
I tried to do it with simply setting action ="webapp2 location" but it is throwing the bellow error
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 even added the machinekey element to web.config
but it is still showing the same error.
This is the code for webapp1 form which sends data to webapp2

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'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 strange issue happening while submiting a form:i have this in my form:
<input type="radio" name="type" onclick="document.getElementById('Type').value='Publiser';" />Publisher <br />
<input type="radio" name="type" onclick="document.getElementById('Type').value='Advertiser';" />Advertiser
<%: Html.TextBoxFor(m => m.Type)%>

I'm using ASP.NET MVC 2 and am struggling with saving child entities. I have an existing Invoice entity (which I create on a separate form) and then I have a LogHours view that I'd like to use to save InvoiceLog's, which are child entities of Invoice. Here's the view:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TothSolutions.Data.Invoice>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Log Hours
</asp:Content>.......
In the SaveHours action, it properly sets the values of the InvoiceLog entities after I call TryUpdateModel but when it does SaveChanges it doesn't update the database with the new values. Also, if you manually update the values of the InvoiceLog entries in the database and then go to this page it doesn't populate the textboxes so it's clearly not binding correctly.

Initially before page load I declared list string variable
List<string> Emails = new List<string>();
Then I am adding value in for each as
Emails.Add(Convert.ToString(item["E-mail Address"]));
I checked value are ading properly. Then on btn_click event I am retrieving value as
foreach (string emailid in Emails
{
Response.Write(emailid .ToString());
}
Nothing is displaying, it seems on form submit list string is initializing.
