MVC :: Handling Form Controls After Ajax.BeginForm Submission?
Oct 12, 2010
Currently I have a comments section integrated into a blog I am writing. The comments are Ajaxified, when you post a comment the comment list auto updates with the comment you just added. Everything is working great but I would like to do some cleanup after a comment is successfully posted. Specifically I would like to disable the textarea and submit button which I would have no issues doing through javascript by using the AjaxOption OnComplete parameter. To avoid double posts or just plain abuse. I know I will need other safegaurds as well but this is my first step. The thing is Ajax.BeginForm does not give the form an id or name so I can not reference the form in javascript. Is there a workaround here? Can I disable these form controls from the controller?
Here is my code.

I was able to find examples throughout the internet that more or less accomplished what I needed to be done, but now I have run into some problems. I need to be emailed the form data when the users submits it and then the user needs to be redirected to a thank you page, in this case "thanks.asp". I have been unable to get the form to redirect users to the thanks page, and in my efforts I think I might have messed the email process up as well.

I have created a form with Field Validators for visitors to fill out on my website. When the form is submitted it inserts a record into a SQL database, sends an email notification and opens a Modal Popup. In the Modal popup are links where visitors can then download trial software.
My problem is that even if the form does not validate correctly, so there are no errors, the Modal Popup is still displayed. Does anyone know how I can make it so the form has to validate correctly before the Modal Popup will be displayed? I am somewhat of a newbie to ASP.NET,

When the Modal Popup opens, the visitors are then able to click on a link to download the software.The problem I am having is that even if the form does not validate correctly, so there are no errors, the Modal Popup still comes up. Is there a way to not have the Modal Popup show unless the form is validated correctly?

ASP.NET MVC - Multiple Buttons on a Form this is what I am trying to do too, except the first answer doesn't satisfy my requirements and the second one uses formcollection. I am not passing formcollection. I am passing values to the ActionResult method, because in my scenario, it doesn't make much sense to use formcollection, because user is hardly filling out any data. I really prefer using SubmitImage at the moment, so I would prefer if your solution doesn't involve me switching to css or input type etc. EDIT: I'm using Ajax.BeginForm and that seems to be the problem rather than Html.SubmitImage

When I put a part of my form in a partial view, all form parts get unobstructive syntax except the form elements in the partial view. The only way I found how to "apply" the unobstructive syntax, is by starting another form inside the partial view.
@using (Ajax.BeginForm("SubmitHandler", new DefaultAjaxOptions()))
{
@Html.EditorFor(m => m.Name)
@Html.Partial("MyPartialView", Model)
}
PartialView:
@Html.TextBoxFor(m => m.SomeContent)
<input class="text-box single-line" data-val="true" data-val-required="This field is required." id="Name" name="Name" type="text" value="">
<input id="SomeContent" name="SomeContent" type="text" value="0">
So only the input element from the View has the unobstructive syntax and the partial view hasn't... Is there a way to apply unobstructive syntax inside a partial view, wich doesn't require you to begin a new form?

point me to a source where I can learn to create a form using dropdown, radio buttons, and other controls and then have web users submit information to me via email or post to SQL database so that it can be used. Do I need to be looking for sources via other languages such as php or javascript or can this be done easily using asp.net and visual studio.

I have a web forms web application (asp.net 2.0). When the user submits the form I have the submit link actually going away so they can't submit it again. However, they could press F5 and that is causing another insert into the database, which I don't want to have happen.
Is there a setting of some sort that I can set if/when they do press F5 to tell the page - don't submit again?

My web app has payment form that need to be submitted to another ASP.NET page (lets call it http://vendor.com/getpay.aspx)residing on another server.
That page will do some mumbo-jumbo works and then redirects it to the acutal
payment gateway site.
when i post my payment form to getpay.aspx via simple HTML form, it works and redirects fine.
if i change the form and its hidden inputs to server side controls, it doesn't work. their page is throwing viewstate exception.
I need the form hidden inputs to be server controls so that i can bind some values generated by my code behind.(i think i can do this like the classic asp way using <%= %>, but it is like going back in standard!)
I tried HttpWebRequest in the code behind, it posts the form but the browser doesn't redirect to Payment Gateway page. I am posting the payment info over non https, how can i prevent the user tampering with the posted data?.I want to validate the payment form in the backend then post it, i couldn't trust the user input data.Also the result was returned to my redirect page with query strings appended. It is also happening over the non https. how much i can trust this redirect data?

I have an asp.net page in an iframe where all links target _blank
<base target="_blank" />
But I want the form on it to submit to _self (i.e. the iframe where the page is located) when the one button is clicked. The form is an <asp:Panel> with an <asp:Button> control for submitting it.
Where can I set the target for this form? Since there isn't a <form> tag or an <input> tag in the file (ASP.NET makes them when it renders the page), I don't know how to change the target to override my <base> tag.

I am building a simple support call system and part of the system requires that the engineer go in and update any calls he/she is working on. What I was wanted to do was make it so that when the engineer types in all his info and then hits update, the formview not only posts the data he/she has added to the database but also then sends an email to the user with the updated details.

i have a form which allows the user to key in the data and then submit.
if everything works well on this action result, then i will redirect the user back to a thank you page.
my problem right now is that when the user click on the back button, they will be able to go back to the form page and the inputs will still be there.
and if the user just click on submit again, i will be getting some potential weird bugs.
so in terms of asp.net mvc, what's the best way to handle users who click on the back button?

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.

An outside vendor did some html work for us, and I'm filling in the actual functionality. I have an issue that I need help with.
He created a simple html page that is opened as a modal pop-up. It contains a form with a few input fields and a submit button. On submitting, an email should be sent using info from the input fields.
I turned his simple html page into a simple aspx page, added runat=server to the form, and added the c# code inside script tags to create and send the email.
It technically works but has a big issue. After the information is submitted and the email is sent, the page (which is supposed to just be a modal pop-up type thing) gets reloaded, but it is now no longer a pop-up. It's reloaded as a standalone page.
So I'm trying to find out if there is a way to get the form to just execute those few lines of c# code on submission without reloading the form. I'm somewhat aware of cgi scripts, but from what I've read, that can be buggy with IIS and all. Plus I'd like to think I could get these few lines of code to run without creating a separate executable.

using System.Data;
using System.Data.SqlClient;
namespace orderfinal

public partial class _Default : System.Web.UI.Page

}
protected void btnSave_OnClick(object Src, EventArgs E)
{
if (Page.IsValid)
{

I am having problem with multiple clicks on submit button. Multiple clicks cause duplicate record insertion in database. On the form, I have used validation controls. Also I have to make some validations at server side, so I can't use javascript to prevent multiple clicks.
