Do all comet style applications require a loop somewhere in the application on the serverside to detect updates/changes? how the logic behind a loopless comet style application would work?

I'm trying to on Page_Load hide all my RadioButtonLists but I can't seem to get the syntax quite right
I'm guessing I've got to use the FindControl syntax something like this
CType(FindControl, RadioButtonList)
And then I'm guessing I will have to loop through each RadioButtonList and set the Visible = False attribute on it.
I seem to be getting an error with the code above.
I need to perform update operation in a datatable without using loops. Is there any way to perform update in a datatabel...
View 3 RepliesNot sure why this is messing with my brain so much today, but I have a SQLDataReader that loops through "Customer" records. In each loop there are MANY other conditions that need to be validated. When a condition fails I want it to move on to the next record in the reader. As you see from my code below, I have simply been exiting the for loop and then checking if I should run other loops all the way down. I want to simply move back to the top of the While Loop for another pass when something like this happens:

Thinks at a backgammon online multiplayer game with over 100, or even 1000 online users. The game communication is done using Ajax + 3 seconds Comet connection interval + ASP.NET technology. Is this a real scenario ?
Didn't so many Comet open connections block the server resulting in big latency ?
I'm trying to implement an auction website and I search in web the Ajax Push is the best way where I can use! So, I'm finding some samples in web to learn how to implement Ajax Push (comet) in client and server. By the way, I find some samples in ASP.Net Webforms, but no in MVC version. I'd like to find a demo, sample, anything ... that use MVC

View 2 RepliesI'm making an application with server sided variables that change every second. Every second those new variable need to be shown at all the clients that have the webpage open. Now most people told me to go with comet because I need to push/pull the data every second, now I've got a few questions: What would be a better solution looking at the fact that I need the new data EVERY SECOND, pulling from the client or pushing with the server?
Also the item ID's that are on the server side (with the variable's that ID got) can change and when the client refreshes the page he needs to get the oldest (and living) ID's. This would mean that my jquery/javascript on the client side must know which ID's he got on the page, what is best way to do this? Last thing is that I can't find a good (not to expensive) comet library/api for asp.net (C#). Anyone ever used a comet library with good results? We're looking at a site that should be able to have 2000 comet connections at every moment.
I implemented a chat using the COMET "way" described in this article: http://www.codeproject.com/KB/aspnet/CometAsync.aspx
In this example, the client connects for 5 seconds every time. I wanted to hold the client longer, for about 10 minutes.
My problem is - how to detect if the client disconnected during those 10 minutes? I tried using Response.IsClientConnected but it returns true even if I close the client. There must by some inidicator since the socket gets disconnected if I close the client.
I am looking for a free implementation for Comet or Push. Here is an example of chat done by comet:http://www.phpchatsoftware.com/phpbb/I have my own server.Is there any thing like this?P.S. I am using asp.NET, on server and jQuery on client.Is there anything new? or maybe this is the last technological free open source achievement:http://www.codeproject.com/KB/aspnet/CometAsync.aspx ?
View 4 RepliesMy date picker has no style as in it doesnt seem to be recognising the style sheet
[Code]....
and my html
[Code]....
My <style> for thumbnails currently looks like this:
<style type="text/css">
img.TN {
width: 100%;
margin-bottom: 5.294%;
cursor: pointer; }
</style>
This is annoying, because I have to apply this style to every single thumbnail image individually, when there could be any number of them on the screen at any given time. All of the thumbnails are inside a single <div> that groups them together, and I'd like to apply a single style to the <div> that will push the attributes I need down to all of the the <img> elements nested inside, regardless how many thumbnails there are.
I'm using ASP.NET 2.0, and CSS 2.0
What is the correct way (or best) way to implement Comet, HTTP Push, or Reverse AJAX?What .NET implementations would you recommend?

View 3 RepliesI'm trying to include script and style references that will not break on deployment, however I can not even get the references to work locally. I have tried using Url.Content() and MVCContrib's <%=Html.ScriptInclude("")%>.
My scripts are in a Scripts folder on the root of the site; my styles are in the usual Content/css/ folder.
The scripts render like this:
<script type="text/javascript" src="/Scripts/MicrosoftAjax.debug.js" ></script>
This will not work in a view page in the Views folder. What am I doing wrong and what is the best way to handle this?
I would have thought Url.Content() would at least work for styles but used in my master page, the link rendered
<link href="/Content/css/Site.css rel="stylesheet" type="text/css" />
This does not work, because the Master Page is in a Shared folder, so what is really the way forward with this?
I'm in the process of styling an asp.net menu and I'm trying to understand the meaning of the StaticSelectedStyle-CssClass and StaticHoverStyle-CssClass parameters.
My understanding is that the styles defined with these parameters are applied as CSS classes to the relevant elements, whenever needed. So I created my menu as follows:
[code]....
So as you can see, StaticMenuStyle and StaticMenuItemStyle are applied, but not StaticSelectedStyle-CssClass or StaticHoverStyle-CssClass. Not sure why. I know I can use selected but isn't the expected behavior that StaticSelectedStyle-CssClass be applied??? By using selected I make assumptions as to what .NET does behind the scenes and that's not right.
I am working on a web site for an optical company. The company works with people that have minor visual impairment up through major impairment, some requiring special equipment in order to view web pages.
Because of the diverse client requirements, we are planning to make available, an option which allows the client, at the time of viewing, to select (stored in a cookie, option hooked to an ASP.NET checkbox) that will make the text size on the page larger and remove some of the pictures that are not required.
The text size is set in the DIV tag, Style "font-size: ##". What I want to do is when the checkbox is unchecked the page will use a normal size and when it's checked the ASP.NET page will change to a larger font. I am not sure how to change a DIV tag (client-side) with a server-side call.
One person elsewhere recommended that I dynamically create the div tag server-side (Response.Write()) but I don't want to use that if there is another way. Just seems like it will be more overhead when whats needed.
I want to add a style A:Hover to a HyperLink control from code behind.
I can do like this :
HyperLink hlRow = new HyperLink();
hlRow.Style.Add("color", "#000000");
hlRow.Style.Add("text-decoration", "none");
But how can I add styles for A:Hover for the hyperlink control? Do I need to define a class and associate that class with this control, if yes how?

There is a website with a master-page, set of css-files,... menus. It is necessary to implement another one that will have same (or at least very similar) look-and-feel. And also it is necessary to have look-and-feel in sync.
I've tried to find for appropriate solution (at least idea, not implementation) in the internet but didn't find anything.
use an additional project (class library) that will contain an implementation of the master-page and all its comnponents (menus, images, css, etc will be stored as resources), this project will be refferenced from all web-sites that need to sare look-and-feel.
