I have a registration page I enter the details of the customers and redirect to another page for capturing photo and I come back to the registration page. I want to retain all the values i entered when i land on the registration page.
I am fairly new to MVC and just trying to achieve something which I think shouldn't be too complicated to achieve. Just want to know what the best approach for that is. I have an Event-RSVP application (NerdDinner kind) where you go to view details of the event and then click on an AJAX link that will RSVP you for the event.
<% if (Model.HasRSVP(Context.User.Identity.Name)) { %> <p>
You are registered for this event!
<%: Ajax.ActionLink("Click here if you can't make it!", "CancelRegistration", "RSVP", new { id = Model.RSVPs.FirstOrDefault(r => r.AttendeeName.ToLower() == User.Identity.Name.ToLower()).RSVPID }, new AjaxOptions { UpdateTargetId = "QuickRegister"}) %> </p> <% } else { %> <p>................
I posted this on Stack overflow [URL] but have not had a solution, just completely different way of doing it without using the Ajax.* helpers so I'm wondering if anyone has an Ajax.* solution here?I'm using MVC 3. I have a method on the controller that returns a Json object, according to this question it should be returned to me as Json, but I am finding that is not the case[URL] here's the code that I have:
[Code].... And the controller: [Code].... The first message box displays the response text which is:{"Success":True, "objectId":"testing"} the second message box displays undefinedSo it is coming back to the client correctly, I'm just not sure how to get it out?...Stefan
I know that I do not want to actually use an Ajax.ActionLink from within a JavaScript function, but for the life of me I cannot figure out how to replicate the behavior. Here is what I have in my MVC 3 RC2 _Layout.cshtml:
[Code]....
I do NOT want to use:
[Code]....
Unless that can be made to populate at runtime, on demand from a script. manually clicking the ""Load Menu" ActionLink works exactly like I want except it requires the user to click the link; I want to do that for them... in this case from the Body onload event.
I have many Ajax.ActionLink's on my ASP.NET MVC (v1) page that perform destructive operations. This is "legal" because I set HttpMethod to DELETE in this case so it's not a destructive GET.
My question though is how to mitigate XSRF attacks on this operation so that other sites cannot craft this same Ajax DELETE request to delete user data from another site. This ActionLink does appear within a form that includes <%= Html.AntiForgeryToken() %> but since ActionLinks don't post the form, the anti-forgery token doesn't go to the controller, so it can't validate it.
1) Polls EF model (Poll (ID,Text),PollQuestions(ID, PollID, Answer),PollStatistics (ID,VotesCount)) 2) Action in Home Controller named Poll which returns Poll model 3) Action in Home Controller names PollResult which returns PollStatistics model 4) On Partial View Poll (radiobuttons using PollQuestions list), ActionLink to post pack 5) On Partial View PollStatistics results information 6) In Home View <div id="Poll">{Here is shown Poll PartialView}</div>
I'm quite new to MVC tech. so the question would be how can I manage Ajax postback when ActionLink is pressed and show up polls result using PollStatistics? (How does result view is passed?) If it's possible - just simple example :)
I've spent a while trying to figure this one out, . I am trying to implement a simple jax.actionlink(first time using) on rows in a table to remove the record from the user control. The ActionLink httpMethod is set to POST but it is not even hitting the Post action I have in the controller. It just gives me a 404 Resource not found error everytime.
I checked fiddler and the reason why I think is because its doing a GET instead of the value i set of POST. I dont have a get method for this since its just an ajax call to delete a record and return a partial view back to the div. I put a breakpoint in the POST method and definitely is not hitting that method. I'm not sure if its something simple or a configuration/routing issue or IIS issue. I've tried in chrome and IE8 just in case.
using System; using System.Collections.Generic; using System.Linq; [code]....
When I click the action link in IE the controller code runs but the div is NOT updated. Do it in ANY other browser and it works just fine. Is this (yet another) known problem/bug with IE??
I've got problem with generating ajax anchors. I'm using simple
Ajax.ActionLink("test", "Test", new AjaxOptions { UpdateTargetId="test", HttpMethod="GET" }) and the generated markup is: <a data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#test" href="/Home/Test">test</a> which, obviously lacks the onclick="Sys.Mvc.AsyncHyperlink.handleClick(...)" attribute.
I am using the AjaxControlToolkit 3.0.30930 (the most recent). I have a very simple page with an UpdatePanel. A button on the UpdatePanel invokes Response.Redirect and passes the URL of a Click Once application on the same server. This works well if I run the website on my local system (Windows 7, IIS 7.5).
If I run the website on a remote system (Windows Server 2008, IIS 7.5, same settings) the redirect simply does not work when invoking the page from remote (using the IP address). Instead a postback is executed. Even if I use the IP address of the webserver to invoke the website locally on the webserver, the redirect does not work. Using http://localhost on the webserver the redirect works well.
I tried another test page with no UpdatePanel: The redirect works well in all scenarios.
I tried out to invoke the ClickOnce application using a link instead of Response.Redirect: The redirect works well in all scenarios, even with an UpdatePanel.
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TestWithUpdatePanel.aspx.cs" Inherits="TestWithUpdatePanel" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
[Code]....
Even if setting EnablePartialRendering to false, the redirect works. This is a big clue, that the UpdatePanel causes the problem.
I have a website, where I load some info into 6 table rows.
Every row loads a different thing and it lasts a different amount of time.
Loading of the whole table takes a lot of time (5-15 secs), so What I would like to do is to load every row with an AJAX UpdatePanel (or 6 UpdatePanels) like this:
When the loading of one row's data is finished, the table row is displayed with the data.
Then row by row finish loading and are displayed too.
I have an TabContainer which contains a user control. The user control contains a formview. When I try to update the formview I get an error "Object reference not set to an instance of an object". I had the formview in the tabpanel and it worked. I decided to make it a user control just to clean it up a bit since I have several tabs, each containing formviews or grids.
This works in IE8 on my local machine (of course), and works on FireFox on the server, but in IE the content doesn't update unless I manually refresh the View. Here's the code:
[Code]....
So it's just some jQuery that replaces the body html with the PartialView data. As I said, this works locally no matter what, and works with FireFox from the server. I'm not sure why the content isn't updating in IE. The code is running correctly and returning the View as expected. I even slapped the cache: false on the jQuery GET so I didn't run into that delightful problem. why the MVC View isn't updating in IE?
