JQuery :: Modified ListBox Not Posting Back Modified Values?

Aug 27, 2010

I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:

$("#MyList_btnAddAll").click(function(e) {
$('#MyList_lstAll option').appendTo('#MyList_lstSelected');

The code has two ListBoxes in fact, one a "source" and the other a "destination". As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected. These are rendered in the browser as <select> elements, as you'd expect.

The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback.

I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data? But in the codebehind after postback the ListBox contents haven't changed. Does anyone know what might be going on and what I can do about it?

ListBox Values Not Posting Changes After JQuery Manipulation?

Sep 3, 2010

have an ASP.Net page with two ListBox components, rendered in the browser as <select> lists. I'm using jQuery to move elements from one list to another by manipulating the DOM. I then select all elements with the mouse and postback the form. That way, all the list elements are posted with the form.When I submit the form, in my button_save() event handler, the Request.Form[<<listbox ID>>] values are correct. However the ListBox controls themselves, specifically their Items collections, do not reflect my changes.I've also used Fiddler to modify the select items and submit the form. Same as above, the ListBox values are no different, though the Request.Form values are. Would anyone know what's going on or what incorrect assumptions I'm making?

Retrieve JQuery Modified InnerHTML From C#?

Mar 25, 2010

I'm trying to access the innerHTML of a span tag modified by jQuery using C#. This is my first project shunning the AJAX libs in favor of jQuery, so I'm not sure how I can get the codebehind to recognize the manipulated innerHTML. I've set all the spans I want to tap into with runat="server", but all I pull are the values I've set when the page was designed.

What steps should I be taking to enable communication between the client-side and my codebehind, and am I even using the best practice here?

C# - Posting Back With JavaScript / JQuery?

Feb 25, 2011

I have a keyboard-controlled menu which I did with jquery (When I press down, it marks second option and so on...)

But after I select the option I need, I want to click enter to call the button's OnClick method as if the user really clicked it. Which means I have to do a postback.

how do I do that?

JQuery Load And Datalist Linkbutton Not Posting Back

Feb 8, 2011

I am loading an aspx page into a div using jquery.load(). The aspx page loaded into the div has a datalist. Each datalist item has a linkbutton. My problem is that the linkbutton is not causing a postback though. Strangely, if I change the linkbutton to a button, it does postback. Also, when loading the page normally (not from a jquery.load event), the linkbutton performs correctly. What is it that causes the linkbutton to not cause a postback when loaded this way? And is there a better way to handle this?

IIS Removes If-None-Match And If-Modified-Since Headers?

Mar 1, 2010

I have an ASHX handler or an ASPX page (the problem happens in both cases).

The web client sends a request containing If-None-Match and/or If-Modified-Since headers but context.Request.Headers.Get("If-None-Match") or context.Request.Headers.Get("If-Modified-Since") is null in the handler.

The same script works in my local development machine but it doesn't work in the online machine (both are running IIS7 on Win 2008, .NET 3.5)

Is This Modified C# Singleton Pattern A Good Practice

Feb 9, 2010

I'm developing a blog application shared by non-profit organizations. I want each organization to be able to change their own blog settings. I have taken a singleton pattern (from BlogEngine.net) and modified it. (I understand that it is no longer a singleton pattern.) I have tested this approach and it seems to work fine in a development environment. Is this pattern a good practice? Are there issues, which may arise when this is placed in a production environment?

public class UserBlogSettings
private UserBlogSettings()
public static UserBlogSettings Instance
string cacheKey = "UserBlogSettings-" + HttpContext.Current.Session["userOrgName"].ToString();
object cacheItem = HttpRuntime.Cache[cacheKey] as UserBlogSettings;
if (cacheItem == null)
cacheItem = new UserBlogSettings();
HttpRuntime.Cache.Insert(cacheKey, cacheItem, null, DateTime.Now.AddMinutes(1),
return (UserBlogSettings) cacheItem;

(Portions of code were omitted for brevity.)

Configuration :: Modified .vb File Not Applied After Rebuild?

Oct 19, 2010

I recently purchased the source code of an existing DotNetNuke module in order to make a few modifications. The source of the module contains various .ascx, ascx.resx and .ascx.vb files. as well as a main.dll file. Lets call them:


I'm using Visual Studio 2008 PRO.

I've made a few changes to "myfile.ascx.vb". When I rebuild "my_module" via Build --> Rebuild my_module, I get confirmation that there are no errors in the Error List. I then upload a fresh copy of "mydll.dll" from the "/obj/release/" folder on my local machine up to the "/bin/" folder on my DotNetNuke site.

The issue that I'm having is that the changes that I made to "myfile.ascx.vb" are not appearing on my DotNetNuke site. Are there additional files that need to uploaded? I've checked timestamps on all of my local files and the only files that are updated after the build is "mydll.dll".
