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 a 2007 excel addin app (VS2005) which calls a web service (also developed in VS2005). When the webservice returns a large amount of data I get the following exception
System.InvalidOperationException: There is an error in XML document (1, 14493956). ---> System.Xml.XmlException: '', hexadecimal value 0x1C, is an invalid character. Line 1, position 14493956.

How can I call a URL ex.
[URL] and get the values returned from it in VB.NET ?
What am I missing here. I just want to pull the first one returned from row.detail in an MVC2 view, how would i do this without a foreach loop? This code currently works, but i just want the first one listed. I know this may be simple, but i am drawing a blank.
if (Model.App != null)
{
foreach (var row in Model.App.Instructions)
{
<input type="hidden" value="<%= row.Detail %>" id="ixd" />
}
}
Provided 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];
poclib caller = new poclib();
SU1I1001 callerItem = new SU1I1001();
callerItem.AcctNo = "0010029004000370";
callerItem.transno = "12345678901234567890";
caller.end
stringset = caller.SU1I1001(callerItem);
*/
}
I have the following javascript:
$.post("/Authenticated/DeletePage/" + PageId);
showStatus("Page deleted...", 10000);
I would like to instead pass showStatus() text that is returned by the $.post() call, rather than hardcoded text. How do I do this?
I've put together some jQuery AJAX code using some tutorials I found on the internet. I'm new to jQuery and want to learn how to do things betters. I have a coworker who put together a beautiful web application using a lot of jQuery.The thing I'm most confused about here is: why is it necessary to use the ".d" when referring to the response of my web method and what does it stand for?

I 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.
I am getting above error when I executing a method of Dll in VS 2005 and DLL is made in VB6 which is interoperable . I am unable to trace the error .

i have an application mvc3, created a link with ajax but confirm property does not works.
index.cshtml is
@{
View.Title = "Home Page";
}
@section Header{
<script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>
}
<h2>@View.Message</h2>
@Ajax.ActionLink(
"Delete Product",
"Delete",
new { id = 1 },
new AjaxOptions { HttpMethod = "DELETE", Confirm = "Are you sure?" }
)
and home controller delete action
public ActionResult Delete(int id)
{
return View();
}
but directly does delete page. how can i confirm box show?
When 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/jquery.validate.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" />

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
{
%>

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 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 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'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.

I 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.
I 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?
I 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??
