View 1 RepliesDoes Ajax post supports the usual validation upon submit of a form?
[code]...
I 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 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.
Im working with asp.net framework 4.0 and I have this code:
form id="form1" runat="server" method="get" action="Profile.aspx"
// some code
asp:Button runat="server" ID="SubmitButton" Text="Submit"
Each time i click the submit button i get this 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 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

I have no idea why my form submit is not passing the model back to the Controller action
Here is the View:
[Code]....
Heres the Controller:
[Code]....
Here is my Model:
[Code]....
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.
I have a simple form on an ASP.NET MVC site that I'm building. This form is submitted, and then I validate that the form fields aren't null, empty, or improperly formatted.
However, when I use ModelState.AddModelError() to indicate validation errors from my controller code, I get an error when my view is re-rendered. In Visual Studio, I get that the following line is highlighted as being the location of the error:
<%=Html.TextBox("Email")%>
The error is the following:
NullReferenceException was unhandled by user code - object reference not set to an instance of an object.
My complete code for that textbox is the following:
<p>
<label for="Email">Your Email:</label>
<%=Html.TextBox("Email")%>
<%=Html.ValidationMessage("Email", "*") %>
</p>
Here's how I'm doing that validation in my controller:
try
{
System.Net.Mail.MailAddress address = new System.Net.Mail.MailAddress(email);
}
catch
{
ModelState.AddModelError("Email", "Should not be empty or invalid");
}
return View();
Note: this applies to all of my fields, not just my Email field, as long as they are invalid.
I have a form with a number of validators. When I click my Submit button the validators fire and I can see my error messages, however the Form still submits and calls my onclick event. Does anyone know what's causing that? The form shouldn't submit with errors.
<asp:Button ID="Button1" runat="server" Text="Submit" onclick="Button1_Click" />
I have a form with normal client validation. Using for example <p>
View 6 RepliesMy page scrolls down a bit, so the problem is when the ASP.NET validation kicks in (its a server side validation that sets a table row to visible if there was a failed validation for a given input box).The problem is, when there is an error, the page scrolls back to the top.How can I force the page to the bottom? can use <a name="asdf"></name> but the page doesn't refresh normally since its a asp.net image button.

View 1 Replieswhen 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."

View 3 RepliesThis 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.
how to submit two different form in same time?
The form is in one page, and i cannot do it in one form because there are two different reference table used.
I have a form that submits to a database.
What I need to do is when the data submits redirect the user to a page where they can download a personalised certificate in either PDF or word, which has been partly populated by the data entered in the web form.
I have an aspx page with many buttons and i have a search button whose event i want to be triggered when user press enter.How can i do this?
View 4 RepliesI'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.
