JQuery :: Finding A Page Object
Feb 9, 2011
Im using the jquery ticker plugin and Ive created a user control to populate it dynamically from a database. To activate it in javascript I have to get the id of the control and because asp.net renders controls prefixed with its own identifier, the javascript has to be like this
[Code]....
How can I use jquery to get what im after just from its name, in this instance 'ULnews' without the 'ctl00_MainArea_ucTicker1_' bit. If I move the control, obviously its generated name will change and my code will break

The error i get seems to be centered around jquery finding what it's in (window,document, etc.). Right now i'm just trying to implement the jQuery datepicker. the project has a master page, where i placed my script references.
<head runat="server">
<title></title>
<link href="~/Styles/Site.css" rel="stylesheet" type="text/css" />[code]...
I have tried document and window for jquery context, but they both throw the same error.

In my global.asax I have url routing setup like below:
routes.MapPageRoute("User Logon", "{Vendor}/Logon", "~/Logon.aspx");
In the logon.aspx page, I have a script that "stylizes" the logon button:
<link href="jquery/css/flick/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" />
<link href="images/style.css" rel="stylesheet" type="text/css" />
<script src="jquery/js/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="jquery/js/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#<%= ButtonLogon.ClientID %>').button();
});
</script>
When I access the page us a url (in debug mode) http://localhost/logon.aspx?v=1 the page loads correctly and the jquery button command loads correctly. But then I access the page using the new url route, I get this error.

I am trying to build a page which consists of different user controls which is divided in 3 columns.I have created a custom class for the page and widgets where the user controls will be loaded in. The custom class needs to be stored in an XML file, and using jQuery sortable for drag-and-drop functionality.At this point, my question is what is the best implementation for loading and saving the states of the page and widgets inside the page? I was thinking about using JSON and WebMethod for that, but I am still missing out the architecture on how I should build the page

I have a class Trans, with properties siteID and TID. I have a generic list of this class, TransList = list(Of Trans).
Now I want to find the Trans in TransList where the siteID is 3 and the TID is T1. There will only be one record. I want to then update this Trans in the TransList (so I need a reference to the Trans). I am trying to do the following, but it doesnt like it.

But it doesn't slide correctly. It jumps instead of being smooth. And it only slows down when the report viewer is involved.

I was wondering to use JQuery with the light wieghted Json and it was a wonderful experience and a very positive performance boosting or the entire project.
I was hoping that anyone else had the same experience with asp.net project geared up with Jquery and Json?

Cant seem to get the following to find the 'skull' button when the 'heart' button is clicked. Here is the JQuery.
$(".voteup").click(function() {
var id = $(this).attr("title");
var userID = $('[id$=HiddenFieldUserID]').val();
var ipAddress = $('[id$=HiddenFieldIPAddress]').val();
var skullButton = $(this).parent().siblings(".votedowntd").children("votedown");
registerUpVote("up", id, $(this), skullButton, userID, ipAddress);
});
And the HTML...
<table width="200px">
<td width="35px" class="votedowntd">
<img src='<%# (bool)Eval("skull") ? "images/skull.png" : "images/skull-bw.png" %>' alt="Vote Down" class="votedown" title='<%# Eval("entry.ID") %>' />
</td>
<td width="130px" style="text-align: center;">
Num Votes Goes Here
</td>
<td width="35px" class="voteuptd">
<img src='<%# (bool)Eval("heart") ? "images/heart.png" : "images/heart-bw.png" %>' alt="Vote Up" class="voteup" title='<%# Eval("entry.ID") %>' />
</td>
<tr>
</tr>
</table>
So basically what I need to do is when one img is clicked, I need to find the other one. Why is what I have not working? Is there a better way to do this?

I am using the jquery Uploadify plugin to upload multiple files. It works great on my development machine; however, when I run the code on the server I get an error that the upload.ashx generic handler (that Uploadify calls to save the file) is not found. Wondering what would prevent it from being found in the server environment. I have even put a copy of the file in every directory to no avail.

I have a nested table structure, a part of which is rendered by a ajax call that returns HTML from the server. The markup looks like this:
<tr>
<td><table cellpadding="0" cellspacing="0" border="0">
<%-- Content will be displayed from ajax call 1 --%>
<%-- Content will be displayed from ajax call 2 --%>
</table>
</td>
</tr>
</table>
.. more html
The ajax call returns the following html
<tr>
<td class="wpss_checkboxtd"><img width="16" height="16" src="../../images/someimg.png"></td>
</tr>
<tr>
<td class="wpss_checkboxtd"><img width="16" height="16" src="../../images/someimg.png"></td>
</tr>
In jquery, I need to insert this html for which i need an element to traverse to so that I can call the html() of that element. Unfortunately, if I use a div, for example:
<table cellpadding="0" cellspacing="0" border="0">
<div id="divAjax1">
<%-- Content will be displayed from ajax call 1 --%>
</div>
<div id="divAjax2">
<%-- Content will be displayed from ajax call 2 --%>
</div>
</table>
the classes are setup such that the div or a span causes other issues.

Is there a plugin that can group data and present it in a tiled format? I'd like to implement JQuery in place of the .NET Listviews that I am currently using. My current Listviews dynamically group three fields per div, with each div presented in two columns by three rows with paging.
I've looked at many plugins through numerous Google searches, and have yet to find one.

I'm new to programming in ASP.NET, but I'm making my way through Wrox's Beginning ASP.NET 3.5 in C# and VB.NET.
I'm at a section where I'm creating a BasePage. I successfully created a BasePage by creating a new class file in my App_Code folder called BasePage.cs with the following code:
[Code]....
If I run that code everything works out fine. The page loads and all is well. But, if I try to do the same thing to a page that uses my MasterPage.master file, I get the following error:
Object reference not set to an instance of an object.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Why is that? In the example code from the book (that also uses a MasterPage.master file), everything excutes and runs just fine. But in my test, I get the above error. I've tried comparing my pages to the books included source pages, but I can't find any differences.

For an MVC 2 app that relies on many partial views and almost exclusively uses Ajax for POSTs/GETs, what would be the best way to implement the setting, passing, retrieval and display (using a JavaScript modal) of these messages?
My forms all POST (by way of jQuery $.ajax) to actions that return partial views (html) that are used to update a in the "success:" part of the $.ajax function.
I was hoping for some sort of mechanism in the master view that could "listen" for any messages that any of these partial views might be "delivering"--through their ViewData, for instance.
