MVC :: Manage Ajax Postback When ActionLink Is Pressed?
Feb 17, 2011
I have next situation:
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 have a textbox added in an item template so I can enter data. But when I press enter in a textbox it caused the page to postback and I lose the data entered. I can tab through fine but why does Enter cause a postback? Can I disable this?
I have used a Ajax calendar with Image control in my application But the problem isĀ when I am leavingĀ the image control It's not Escape If i press Escape button also It's not Escape, any tag for calendar Escape..
I have several buttons on a page, but have assigned some validators and AJAX validator callout extenders to one button in particular. However, the validator callout extenders seem to be firing even if I press a different button. I thought this was the point of setting a TargetControlID (for the valiator callout extender) and a ControlToValidate for the validator itself!
i want to fetch data from Oracle Data base using Tab key , like when user enter ID in one text box and press Tab key it should fetch data in other text boxes , i am using web form.
I am using Crystal Report on my ASP.NET Fw. 3.5 project. My report contains 100+ pages. When I click on next page button on crystal report viewer control my whole page gets postback to server and then second page appears. This take same time when first time report gets loaded.
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.
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.
When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
