VS 2010 - Set Element Value Using JQuery But Did Not Change When Post To Code Behind

Jan 31, 2012

I got a asp: label (hidden by css) to which I store something.

I could not use a hiddenfield since you cannot set a css class on it. I need a css class so I can select it in jQuery. I cannot select by Id since asp.net webforms change your id. I cannot use xxxxx.ClientId, since my jQuery script isn't on that form (oh oh, i miss my mvc)

Anyhow, I pop up a dialog, let the user type sth in. When the dialog closes, I set that label to whatever the use typed in the dialog. That work (I'm testing for now using some alerts) but when I add a button, and in it's click event check the value of taht label, it is still what it originally have been though.

Here is the content of my usercontrol (at run time add as many as needed of them to my view):

Code:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DisputeEntry.ascx.cs" Inherits="TimeSheetDispute.DisputeEntry" %>
<p class="field switch">
<asp:label runat="server" class="disputeReason" ID="disputeReason"></asp:label>

[Code] ....

And in my page, the code that deal with it:

Code:
// Brings up a jQuery UI Dialog containing a textarea to which the user can enter a dispute
// Upon close, place that reason in the hidden input we keep for each date.
function GetDisputeReason(parent) {
var disputeReasonElement = $('.disputeReason', parent);
var existingDispute = disputeReasonElement.val();
var win = $('<div><p>Enter your reason for dispute:</p></div>');
var userInput = $('<textarea style="width:100%">' + existingDispute + '

I upgraded from VS 2008 to VS 2010 and now the AJAX elements are not recognised by the source code editor, e.g. UpdatePanel, ScriptManager, etc. I get warnings in VS and no intellisense for those elements. When I run the site, all the AJAX controls work OK though.

Jquery - Http Post To Code Behind In Asp.net Webforms?

Jan 12, 2010

How can I call a method in the code behind from a jQuery post in asp.net webforms?

In MVC it's simple, I just do this:

$.post("/MyController/MyMethod", { data: somedata; }, function(result) { alert(result); });

but I can't figure how what to put for the first parameter if I wanted to call a method in the code behind in webforms... for example, if I have a method called doSomething() is there a way to stick some location in there so that it will call doSomething() and return data to the callback?

JQuery - Change Event On Select-element Getting Fired Twice When Using Both DOM-event?

Jun 17, 2010

There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:

<html>

<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[code].....

This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.

Getting Value Of HTML Select Element On Form Post?

Mar 29, 2010

I have a View that has a select drop-down list and an edit button within a form. What I want to do is have the user select one of the options from the select element, click on the edit button, and get the value of the selected option in the Controller method.

I created my form with <% Html.BeginForm(): %>

and the Controller "Edit" method should be called.

I looked through several online examples, but each one focused on how to set values and the default selected value of the select element, rather than retrieving it from the code in the Controller method. I tried grabbing it from the Request.Form collection like:

string val = Request.Form["myDropDownList"].ToString();
and also:
string val = Request.Form["myDropDownList"];

Obviously I didn't do this correctly, because I get a null reference exception. Does anyone have the solution to this issue?

Jquery - How To Find The Form Element

Mar 23, 2011

I used to have this one...

at the head part

[code]....

So what changes should i make to the jquery.openid.js to make it work?

I mean in the first case the $this refers to form.openid:eq(0) In the second case the $this refers to #text.openidd and the form is never submitted.

I guess something like this one $this.FindParentForm exists in JQUERY, but i have no clue!

I added the div tag as enclosure for the elements. The form contains other <li>'s etc that jquery messes with. And i would not like that! That's why in my post i believe that the work has to be done in the jquery.openid.js file... something like

$this.GETParentFORM.unbind('submit').submit(function() {
$id.val($this.GETParentFORM.find("li.highlight span").text());
});
$this.GETParentFORM.submit();
