MVC :: Call Ajax.ActionLink From JavaScript Function?
Jan 6, 2011I 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:

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.

WCF / ASMX :: WSDL Made The Call To Web Services But Returned Nothing
Oct 26, 2010Provided wsdl from link below:
http://www.2shared.com/file/zfTUDRl3/poccrm.html
I've been given merely a wsdl above from client, without any further information given, to make a call using c# code but i added as web reference, used the codes below and the client side detected my request and they've returned us proper format xml too, but i cant retrieve it in the string array from the method returned. the "stringset" has became null instead of array[10]. Can anyone give a hint what kind of web service call is it, since it is not using the simple and classic way to invoke?
static void Main(string[] args)
{
//added web reference for wsdl as poccrm
string[] stringset = new string[10];
poccrm.poclib caller = new ConsoleApplication1.poccrm.poclib();
poccrm.SE1I2001 callerItem = new poccrm.SE1I2001();
callerItem.AcctNo = "0010241000007914";
callerItem.TransNo = "12345678901234567890";
callerItem.StartDate = "20-01-2010";
stringset = caller.SE1I2001(callerItem); //here i get null for stringset, but client received the request and returned us value
//same result even I use wsdl.exe converted it to a class file
/*
string[] stringset = new string[10];

AJAX :: Detecting Cause Of Slowness In Update Panels?
Jan 27, 2010I have a page that display a record set inside an update panel. There are also a handfull of checkboxes/textboxes that allow filters to be placed. Each checkbox/textbox is set as an async trigger for the update panel and set to autopostback.
If a single checkbox is clicked the whole filter/render process takes roughly 1.5s.
If I check a filter and then several more before the intial postback is complete I get a postback time of somewhere between 20-50s depending how many boxes I've clicked.
I notice (via firebug) when I check a box that triggers an async postback and than another box the original async post back is aborted. And yet it seems like it still executes (or maybe locks?) something on the server.

C# - Ajax Actionlink Redirecting Instead Of Updating Tag?
Feb 23, 2011When I am making an ajax call the controller is redirecting and not updating my tags my code looks like as follows.
This is in the _layout.cshtml
<code>
<script src="@Url.Content("~/Scripts/jquery-1.4.1.min.js")" type="text/javascript">
</script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>

<script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript">
</script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript">
</script>
</code>
And This is what the web config looks like, I have also tried turning off unobtrusive javascript off with no luck.
<code>
<appSettings>
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />

Controller AJAX Method To Return ActionLink
Apr 4, 2011I 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"})

MVC :: OnComplete Ajax.ActionLink Parameter Not Json In MVC 3?
Jan 27, 2011I 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
How To Mitigate XSRF For MVC Ajax.ActionLink Requests
Jan 2, 2010I 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.
MVC :: Manage Ajax Postback When ActionLink Is Pressed?
Feb 17, 2011I 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 :)
MVC :: Ajax ActionLink Results In Resource Not Found?
Mar 11, 2011I'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.

Ajax.ActionLink Is Not Working - Response.IsAjaxRequest() Is Always False
Feb 11, 2011I have been googling/SO:ing this issue for a while and many seem to be sharing this, but I haven't found any successful solution to my problem.
Using MVC3 and Razor.
Master page contains:
<script src="@Url.Content("~/Scripts/jquery-1.5.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script>
AjaxTest.cshtml contains:
<div id="AjaxTestDiv">content</div>
@Ajax.ActionLink("Update", "AjaxTester", new AjaxOptions { UpdateTargetId = "AjaxTestDiv" })
AjaxTester action method:
public string AjaxTester()
{
if (Request.IsAjaxRequest())
{
return DateTime.Now.ToString();
}
else
{
return "FAIL";
}
}
I always get the "FAIL" returned, to a blank page, not in the targeted div.
Edit: Also note that if I remove the if (Request.IsAjaxRequest()), I still don't get back anything to the targeted div, but instead a blank page.
Edit2: Looking at the HTML generated, this is my link:
<a data-ajax="true" data-ajax-method="POST" data-ajax-mode="replace"
data-ajax-update="#AjaxTestDiv" href="/Area/AjaxTester">Update</a>
Have tried switching the method to GET, to no avail.
Forms Data Controls :: Detecting When The Last Row In A GridView Has Been Deleted?
Dec 6, 2010I have a GridView. One of its columns contains monetary amounts. Underneath the GridView, I have a SqlDataSource which calculates the sum of this column and displays it in a label which is in a DIV called totalsbox (that I have added runat="server" to).
Obviously, if the GridView is empty, I don't want this label to be visible.
In the Page_Load, I have placed the following code:
[Code]....
[Code]....
This works fine. When the Page first loads, if the GridView is empty, the entire DIV is hidden; if not, the DIV is visible and the label displays the column SUM. imagine now the GridView DOES have rows, the DIV is visible and the total is displayed properly in the DIV ("£10.00", say).
I have a RowDeleted event handler in the code behind which contains exactly the same code as I put in the Page_Load. As I delete rows, one by one, the sum is recalculated and displayed properly. But, when I delete the final row, I would expect this code to hide the DIV as the GridView is now empty.
This doesn't happen, however, the DIV remains visible and I have, in the label, something like "£ ".
Why is it that the code works in the Page_Load but not in the RowDeleted event handler?
MVC Ajax.ActionLink Example Doesn't Work In IE... But Does In Firefox, Chrome, Safari
Feb 14, 2010I have the following controller:
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??
