jQuery DataTables server-side processing using ASP.NET WebForms.
Solution:
Darin Dimitrov answered the question using an example which pages and sorts, but doesn't do any searching.
Here's my basic modification of his work to make searching work on his example:

I am using C# ASP .NET MVC and ajax calls. I am able to get the display of the table along with all features. But, I don't understand how do I add a checkbox and button. I have tried dom-checkbox as well but can't get it to work.
My code looks like this:
$(document).ready(function () {
$('#personTable').dataTable({
"bJQueryUI": true,
"sPaginationType": "full_numbers",
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "/Home/GetCustomData",
"aoColumns": [
{ "sSortDataType": "dom-checkbox", "sTitle": "Select",
sName": "" },
{ "sName": "ID", "sTitle": "ID" },
{ "sName": "FirstName", "sTitle": "First Name" },
{ "sName": "Email", "sTitle": "Email"}]
});
});
My Html is :
[table border="1" id="personTable" class="display"]
[/table]
Am getting this error on clicking any of my page link.
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0"
How do i avoid this error.
I'm working on an ASP.Net webpage which will use the jQuery Dropdown Checklist (http://code.google.com/p/dropdown-check-list/). I'm fairly inexperienced with JavaScript and completely new to jQuery.
Basically, my question is: How do you update the selected items in a jQuery DropdownChecklist from the server-side?
NOTE: For details on the solution, scroll to the bottom of the question.
Here's some background to give you a better idea of what I'm doing...
I have a jQuery DropdownChecklist which is being populated when the page loads. When a user selects an item in the DropdownChecklist, the selected values are collected and stored in a hidden input field, then a postback is performed, which allows the server to update a server control. This part is working.
Now, here's my problem. This server control, which is actually a usercontrol has a "Remove" button for each selected item in the DropdownChecklist. When a "Remove" button is clicked, it should cause the associated item in the jQuery DropdownChecklist to be de-selected. So, far I haven't figured out how to make that happen.
Here's some relevant code snippets:
Here's the markup...
<asp:ScriptManager ID="smScriptMgr" runat="server" />
<table>
<tr>
<td>
<select id="s1" multiple="true" runat="server" />
[Code]....
We determined the simplest solution was to call the JavaScript function from the client-side rather than try to do it from the server-side. The ImageButton does have an onClientClick event, but for some reason it didn't work. However, wrapping the ImageButton in a client-side anchor tag and using its onclick event did the charm.
How can I get the active index of the jquery accordion pane when a button is clicked? What I want to do is when a button is clicked in pane 3 for example, I want to store that value and when the page is reloaded, I want pane 3 to remain open.
I intially had this in my server side click and when I hard code a value in for paneIndex it works fine, but obviously, I don't want to do this, I want to get the index on the click and pass that to the script.
string script = "<script type="text/javascript">var paneIndex = " + 3 + "</script>";
if(!ClientScript.IsStartupScriptRegistered("JSScript"))
ClientScript.RegisterStartupScript(this.GetType(),"JSScript", script);
I have a pop-up div contains a table.
I need to make table rows clickable and can be catched by both js and .net server side .
how can I use Request.form to solve this issue? since I've created functions for js part .
The reason why I want to fire sever side event, because I use JS to add option (item) to an asp:ddl in an updatepanel, it will cause error or lose the new option by doing a postback fired by other buttons.
I have a html table. i need to search the table dynamically on the key press of search textbox and apply background to TRs.
I have a jquery to do the functionality. but the page is getting hangged for atleast 5 seconds when there is more number of rows.
I have updater inmage to show while preocessing, image is displayed but when the proccessing javascript the image got structed.
Which processing is fast Client-side or Server-side? for client side processing browser need to download every JavaScript first and in server side programming everything happens on server without downloading anything to user PC? if for a particular functionality we have solution in both javascript and php/asp then what should be chosen and why?

View 3 RepliesWe are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?
View 2 RepliesSuppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.
I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...

Working on an ecommerce site which will be integrated with a 3rd party vendor--that vendor uses different identifiers for stores than we use internally (i.e. their store ABC123 is our 001-321). I'm researching the best approach to inspect incoming requests for reserved query-string parameters that indicate the request is using their identifiers and map the identifiers back to our identifiers (so if the request is example.com/&theirId=ABC123 I want to transform the request to example.com/&ourId=001-321). To do this mapping I need to inspect the provided ID, execute a lookup against the database or cache, and forward the request to the specified page--limiting the modifications to just the query-string parameters (other parameters will need to be maintained, as with the details of the HTTPHeader, etc). So far I'm researching a few different approaches: Implementing it in a base Page (which already does too much, but has the benefit of our Logging infrastructure and some other injected dependencies) Implementing it in an IHttpModule Using URL RewritingUsing URL Routing (looks like routing isn't what I want, feel free to offer insight if you think it still fits) Performance cost is a consideration: the actual number of times this translation will occur will be very small compared to the number of requests not requiring it--perhaps 1%. However for another integrated site we will perform this mapping on nearly every request--would a different approach be better suited to this scenario from the previous?

I'm working on developing a custom control to select items from a predefined list. This is accomplished via 2 ASP.NET ListBox controls, with a few buttons to trigger the movement of ListItems from one ListBox to the other (lets call these ListBoxes lstSelected and lstDeselected).
This is easy enough to do in ASP.NET or JavaScript independently: I have both working. However, if modifications are made via JavaScript, ASP.NET retains no knowledge of this. Is there any way to register the creation of of options in a select tag without AJAX?
I've got a function I wrote quite some time ago that works fine, but I'd like to speed up the process and lessen server load by doing the same job in Javascript.I seem to be able to GET textbox values ok, but I can't seem to SET textbox values (I'm'-a JS noob). Can anyone lend a hand in converting my VB.NET code to it's JS equivalent?

I am working on a page that has multiple sections and each section looks 'almost the same'. Having said that, I want to build the HTML on the server and render it for each section on the initial page load. On subsequent actions, I would do a ajax call and have the server return json data.
The other option is to 'hardcode' the HTML on the aspx page and have the JS do the necessary customizations for each section. The third option is to use an UpdatePanel and do everything server side.
Based on what should I be choosing what approach to use? What approach would you use for a page like this (think of it as a large page having sub sections on it)
Edit: One section has HTML such as user's name, and a table where users can add dependents. Another section is almost the same except its for a 'contractor' so there's additional HTML such as previous work history, but this one has name (readonly) and a table to add dependents just like the first one. Other sections have more or less the same HTML. A user can delete dependents as well, when that happens, I need to update the database and update the section to reflect one less dependent. I was hoping to make any subsequent actions as ajax calls that interact with the server and the database
I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029."
The other relatively smaller reports are coming up successfully without any issue.
I am using SQL Server 2008 R2 64 bit ent. edition and the OS is Win Server 2003 64 bit SP 2.
I have 2 update panels where the server-side button (in a jQuery accordion) in the first update panel should update the second update panel.When the button is clicked, jQuery hides the accordion and displays a results div. This all works fine client side to be fair to IE. The server-side onclick event does not fire though in IE. In Firefox it does! The first update panel is displayed below, here the "btnGenerateReport" event should fire server side.
[Code]....
To add confusion ... if I comment out '$accordion.toggle($effect);' lines then the second update panel does get updated.I'm not sure what other information I can give here. I'm stumped as to why this works with Firefox and not IE.
I want to develop a message bar in jquery which fetches information from server side asp.net code.I know how to connect jquery to call asmx service.I just want to know that, I will be using function from jquery to call asmx service. But to check for latest message on server, i need to call that function at regular interval like timer event. So how can i call jquery function to run at a particular interval to display messages from server?
