C# - Tags List In Stackoverflow?
May 17, 2010
am working on website in asp.net mvc. There is form where user is asked to put some information along with the Tags similar to stackoverflow. this tags information is saved in the same table in field Tags.Now I want to show them a help to select tags from the list (same as in stackoverflow).how can i extract it from the table. Wont it be too much to run the query again and againfor each letter they type, because I will be extracting unique tags from my table. Or should i have another table tagslookup where i should save unique tags.

Technologies involved:
ASP.NET Web-forms
Javascript (jQuery for instance)
Case,To make it clearer let's give the Stackoverflow Users list as an example. This list can be manipulated at client-side. I can search, page and so forth. So obviously we would need to call jQuery.ajax to retrieve the HTML of each page given a search. Alright. Now this leaves me with the first question:
What is the best way to render the response for the jQuery.ajax at server-side? I can't use templates I suppose, so the most obvious solution I think is to create the HTML tags as server-controls and render them as the result of an ASHX request? Nice. That solved we have yet another problem:
When the user first enters the Authors List the first list page should already come from the server completely rendered alright? Of course we could render the first page as well as an ajax call but I don't think it's better. This time I CAN use templates to render the list but this template couldn't be reused in case 1. What do I do?
Now the final question: Now we have 2 rendering strategies: 1) Client and 2) Server. How do I reuse code for the 2 renderings?

I have this food recipe asp.net c# application I'm working on and I would like to be able to insert a list of tags into the database for each recipe. So let's say I have three tags (southern, cajun, gumbo) that correspond to a gumbo recipe. How would I insert these three tags into the database from the UI? Would I store them in a List, run a foreach, and insert each tag individually? I'd really like to be able to somehow use a stored procedure to do this.

i have created a aspx page with the script manager, update panels and so on. Now, when i use some jquery functions which are included inside the head tags, when the page is run, i find the script tags generated inside the body instead of the head tag. i'm using visual studio 2005 only.

I am building a forum and I want to use forum-style tags to let the users format their posts in a limited fashion.Currently I am using Regex to do this.As per this question:How to use C# regular expressions to emulate forum tags. The problem with this,is that the regex does not distinguish between nested tags.Here is a sample of how I implemented this method:
public static string MyExtensionMethod(this string text){return TransformTags(text);}
private static string TransformTags(string input)
{string regex = @"[([^=]+)[=x22']*(S*?)['x22]*](.+?)[/(1)]";
MatchCollection matches = new Regex(regex).Matches(input);
for (int i = 0; i < matches.Count; i++)
var tag = matches[i].Groups[1].Value;
var optionalValue = matches[i].Groups[2].Value;
var content = matches[i].Groups[3].Value;
Now,if I submit something like [quote] This user posted [quote] blah [/quote] [/quote] it does not properly detect the nested quote.Instead it takes the first opening quote tag and puts it with the first closing quote tag.Do you guys recommend any solutions?Can the regex be modified to grab nested tags?Maybe I shouldn't use regex for this?

Firstly, This question may be asked. But I could not get the information i am looking for.
I am creating a website which should take to [URL] where the user enters his account information and it redirect back to my website similar to how stack over flow is doing when we click on gmail image.
I am trying to implement a website in .net.
list a step by step procedure to implement it or suggest some documentation to follow.
I clearly dont want other types of openID implemention where u enter the open id and pick ur open id provider.

I would like to display the "Posted At" in the same format that Stackoverflow and Facebook do. i.e. On this site when I post this question it will display "asked 3 seconds ago" then "asked 3 mins ago" and after a few day it will display the date. My app is C#,

I have downloaded TheWorldsWorstStackOverflowClone. One of the project is called TheWorldWorsts.ApiWrapper, which basically is the core of accessing the API. There is a class called ApiProxy.cs, which has all the methods for the API call. This is good.
Now what I want to do is I am trying to collect data from this API interface and store it in a database. I know the limit to the API call is 10k per day. I.e: I want to be able to call the method in the ApiProxy class 10k times per day, done automatically. How can I do this?
The non-automatic way would be to create a dummy site where when every time I access the site it does all that process, but this not efficient. It seems that I have to write some kind of a scheduler by deploying a web service, but that is too complicated... as explained here. Any other simpler methods?

Is there a way to apply your own CSS tags to <li> tags when using ASP .NET 4.0 menu control? For example, say I have an external style sheet that has tags "class1", "class2", "class3", and etc. I want to apply "class1" to the first menu item. Then if menu item is selected, I want to apply "class2" and if it's not selected, "class3". I played with various 'Static' styles, but just can't get it work. I finally gave up and created my own menu control that extends ASP .NET menu control and provides my own custom rendering. This works, but I'm wondering if there is a way to get it work with built-in menu control.

My aspx page contains a region which is populated trough ajax. The pupulated content is that of the page MyWebpart.aspx. But MyWebpart.aspx contains not only a grid(which is what I need to get trough ajax), it also contains , , , tags because this are required for any aspx file.code to replace inner html with that received from webpart

I have an issue with Firefox. After creating a new template for my website using <div> tags, i noticed that not all tags are displayed when i preview the site in firefox.
I put the sample template in the following location:
[URL]
I was able to verify my CSS with the following link: [URL] and it passed without any problems. The html part is correct as well.
My question is how come two div tags: <div class="header9"></div> and <div id="sidebar"></div> are not displayed in firefox. It works fine with explorer but firefox has issues.
Also the background-color for <body> takes over in the middle, even though i've created a <div id="wrapper"> with all divs inside and background color assigned to white.
I've tried developer extension for firefox but still was not able to find the problem.
It's very annoying that simple (basic) tags such <div> could have isssues being displayed. Does anyone know what am i doing wrong and how to fix that issue?
