Develop Reference

how do create a commenting feature in asp.net which fetches data from database and displays it on webform along with their name?

The sample has been attached for your reference.
I am trying to create a commenting system similar to the reference. The Users should be able to comment about particular issue and i want it to display as a stack in a panel like view along with their name and timestamp on the comment above. I have no clue how to display them as a stack with their name on top of comment apart from doing it in a gridview way. Any help is much appreciate

First of all, you should at least check out all the controls for the platform that you are working on. Apart from Grid, there are many controls which you can utilize to build the page that stacks comments.
You can use check out all the data controls here The choice is up to you but i would suggest that you go with Repeater as that is built for producing such repetitive blocks.
you can sort your comments data by "id desc" so that latest comments show up on top. The look of the blocks depends on how you style them using css.

Anchor tags in asp.net 2.0 to pass variables to another page

I'm learning asp.net 2.0 for a project and so far after several tutorials and searching it's going pretty well. However what I am having problems with is I have a main page with a huge list of anchor tags and need a way to have the user click one and redirect to another page along with a variable or two so the new page an be dynamically created pulling database info based off those two variables. So far I can do this just fine for one item with a form, submit button and postback but with a huge list of anchor tags it doesn't really make a lot of sense. I really don't know what I'm trying to do is called so I don't know what to search on the internet to learn how to do it. I'm hoping someone may have a suggestion to point me in the right direction.

<li>Custoemr1</li>
<li>Custoemr2</li>
<li>Custoemr3</li>
<li>Custoemr4</li>
</ul>
above is the sample list and it doesn't have to be anchor tags I just need to be able to not have to write a new form for every customer , it's an odd project trying to combine a lot of database info as well as a lot of static pages.

ASP.NET MVC Selectable Tree/Grid/Search Data View

I'm working on a web app in ASP.NET MVC 3 using the Razor HTML 5 engine and C#. The client wants something pretty complex and I would like to know if there is any examples out on the web that might show me how to begin setting this up. Here's what they are looking for:
I have a very large SQL database (25,000 rows). They want to be able to select the data using three different views on the same page.
The first will be a tree and using similarities in certain columns of the table will be how the tree is broken in to sections.
The second will be a grid. This will be just one entire list of the everything in the database that you can scroll through. Of course there has to be some sort of virtual scrolling because loading 25,000 rows rather quickly isn't going to happen.
The third will be a search box where you can type in the code and select it that way.
All three of these need to be linked so that when you type a code in the search box it will select it in the grid and in the tree. If you select it in the tree then it will be selected in the grid, and if you select it in the grid then it will be selected in the tree.
They also want me to remember the last selection when you navigate away and be able to type a code n on a different page and go directly to this page with the item you typed selected. Therefore, I need to be able to use MVC's capabilities to establish a hyper link for every item in the list (I assume that would be the way to do this)
This is honestly the first time I've worked with ASP.net MVC and I feel like I may have bitten off more than I can chew with this project so any help would be greatly appreciated!
They would rather it if I didn't need to include any extra dll's so if there is a way to do this without third party tools that would be even better, but at this point I'm just looking for anything.

A few random ideas/thoughts about this:
This is kind of a big project as your first MVC app - hopefully you have some experience with HTML/Javascript/jQuery since it's going to require a fair amount of glue code to make everything work together. There is no "here, do this" solution.
There are a bunch of different free/open source projects for treeviews and grids. I've used jqGrid for a number of projects - it works well. It has a decent API and is fairly configurable (although it may take some digging to find the example code you need).
For a treeview, you can try jsTree. I haven't worked with it, though.
I'd suggest starting with just the treeview, or just the grid and get it working first. Then add the other control and get it working. Then add the search. Finally, I'd work on getting everything to work together.
To handle navigating to a specific selection, you can pull information off the query string from Javascript.
Realize that most of this is going to be happening in Javascript on the client side, not much server side.

jQuery Core/Data or Custom Attributes(Data-Driven)

A similar question was asked here in storing information in a given html element.
I'm still green to jQuery, but I'm looking for the best way to store information on the page. I have a Repeater that holds one image per item. These images are clickable and can fire a given jQuery event. The issue I'm having is, the objects that the Repeater is bound to holds some specific information(such as "Subtext", "LargerImage", etc) which I would like to be accessible from the page.
Core/Data in jQuery accomplishes this just fine, however we would still need to build the jQuery statement from C#, as all the data is stored on the server. To clarify a bit, this is storing information on the page from a database, which is a bit different than arbitrary information being made available through jQuery.
I'm not restricting this question to "how to bind a custom attribute to an element", because I did come across an idea of generating a JS Struct from the C# codebehind to store information, but I'm avoiding any code generating code scenarios(or trying to).
Custom Attributes from HTML5(ie, "data-subtext") are also a possibility as I can easily add those from the itemdatabound event:
sampleImageElement.Attributes.Add("data-subtext", "And this what the image is about");
I'm a bit confused on browser support for this specific attribute though, or if it is even best practice so early in the game. If custom attributes are the way to go, that's an easy change to make happen. If jQuery can accomplish the same, I'd love to be pointed that way at least for my own understanding.
Any thoughts are greatly appreciated.

I'm answering this question only for the record keeping purposes of stackoverflow, as this is the solution I've moved forward with for this scenario. An AJAX call is completely warranted for any larger datasets and is a direction I would definitely go otherwise.
I went ahead with the "data-" field in the HTML5 spec, provided by the jQuery meta-data plugin.
I'm wrote a short extension method on the Web.UI.AttributeCollection class called "AddMetaData", which accepts an IList as well as a string "Key" to ease the attachment to a given page element.
I'm not marking this as the answer just yet, as there might be some community feedback on my own direction.

To clarify what happens in ASP.NET, once the page is served to the client, the objects that the Repeater is bound to on the server are destroyed and are then recreated upon each page postback.
It sounds like you want to achieve some kind of tooltip effect where the contents are retrieved from the server through AJAX? There are numerous different tooltip options available
jQuery Tooltip plugin
Random.Next()'s jQuery AJAX tooltip
dhtml goodies AJAX tooltip
clueTip
that can be used to do this. You could then set up a webservice or page method to retrieve the relevant data from your datasource.
Of course, you could have the content rendered in the HTML sent to the client when the request is processed and simply hide this markup. Then write your own plugin to display the markup in the form you require.

ASP.NET C# Properly Generating HTML for Page

I realize this is probably a fundamental thing I should know but I am self-teaching myself C# and asp.net so I am a little lost at this point.
I right now have 2 pages. One is an .aspx (with aspx.cs file included) that is blank and html is generated for it from a Page_Load function in the cs file. The HTML is very simple and it is just an image and some text.
The second file is a shtml file which has lots of things, serverside includes, editable and noneditable areas. I want to put my webapp into this file. My asp.net app uses Response.Write to just write out the html. This does not flow well with this page as all that does is write it at the top of the page which is because it is ran first and generates it at the top.
How can I make it to where I can generate HTML code inside the page, like within a specific DIV so it does not mess up the page. Where would a starting point be in learning how to do that.
I should note that I do not need any interaction from the user. All of this should generate right away.

I think you need to read up on some basic ASP.Net documentation and tutorials. Response.Write is not the correct approach - you need to understand how the ASP.Net page lifecycle works and how WebControls are used to render the html.
ASP.Net tries to abstract away having to create your html manually for the most part.

So if i have understood the questions correctly.
You already have an existing page/application (the shtml file) that you want to extend with some new ASP.NET components by including output from the ASP.NET page in the existing page?
This is as not something that is out of the box "supported" by ASP.NET and you "won't" be able to execute the aspx page using SSI. But you can do the opposite, an ASP.NET page does support SSI. So if you are not using any other scripts in the shtml file this might be a solution.
Otherwise the only common solutions would be either to use an AJAX framework and let it call the ASP.NET from within the existing pages or to use an iframe solution. In both cases the client will be resposible for making the calls to the ASP.NET pages and merging the results.
And then you have a issue with controlling the output from the ASP.NET page?
The Polymorphic Podcast has a good article on Controlling HTML in ASP.NET WebForms .

You can add a Literal control to the page inside the div:
<div>
<asp:Literal ID="litMarkup" runat=server />
</div>
then in your code-behind:
litMarkup.Text = "<strong>Your markup</strong>";

I don't know how well this would work for you, but could you try using an iframe to house the ASP.NET page? This should keep it in the specified region and not overwriting your shtml file. It may be something to think about.

If it is necessary that you generate your HTML output from C# code, and you would use this in more than one place, I think you may be thinking of something like what are called ASP.NET Custom Controls (not to be confused with "User Controls"-- though you probably could put together a solution with those as well, using a Literal control as another person suggested). The MSDN documentation would be a good starting point. In general, though, the writing-out-HTML-yourself-from-code model (like you would with, say, CGI applications), is not the usual ASP.NET model of development, as it largely defeats the point of using ASP.NET at all. You'd mostly want to do this sort of thing if you are writing your own web control, though this might be exactly what you are doing (hard to tell from the description).
