I am starting to make my first steps in the asp.net world.
I run into something that wasn' t new to me, though its use in asp.net is something that to me seems totally different from what i knew before.
I'm talking about the "runat=server" clause. Remembering classic asp, vbscript, I learned that "runat=server" was used to instruct the web server to elaborate the vbscript code subject to the clause itself, rather than send it to the client.
In asp.net, it seems to be different. I read that it's used for "server side control" , that is, controls which are "run" on the server side. This is nonsense to me . How can a control be run on the server side, given that the server side obviously doesn't have a Gui (and if it has, probably it has nothing to do with the user session) ....? my suspicion is that a "server side" control, means a control which can be dealt with by a server side script or code behind snippet. But ... is this the right idea ?
I read tons of documentation and articles but it seems none of them wants to be clear about this subject. I wonder how the documentation can be so fuzzy ... don't these guys ever ask themselves such simple questions ? Do they always take things for granted ?

You are right, runat=server means the control is executed on server. Each control with such attribute is processed before page is ready to send to user and as a result only output html is visible for user, not the source code.
To be honest, I never thought about it in your way. It was always like that - if you want your code executed use runat=server. So it may be the reason why it isn't explained much.

By using runat="server", controls are enhanced to enable server side processing.
It means, you will be able to access the control and its properties on server side too. Without runat="server", you won't be able to access the control on server side (code behind file).
It's not about GUI. It's about accessibility to the object and it's properties.

To elaborate on Sandeeps explanation a little more,
ASP.Net objects can be used on a web form, that uses combinations of just plain old HTML and ASP.Net Objects such as the panel control.
So you can do it 2 ways, 1 in straight HTML or 1 as an asp.net object
<div style="float: left;"></div>
or
<asp:panel id="panel1" runat="Server" ></asp:panel>
Now you can also create that object in code behind, or pure code
Dim panel_Container as Panel = new panel
with panel_container
.style.add(HtmlTextWriterStyle.float, "left")
end with
controls.add(panel_container)
I don't know what the exact description is of using runat="Server" is, but I know you need it when using system.web objects on the web form, which is a .aspx page. The server will convert that object to HTML, and send the HTML back to the browser.
So a Panel object is a set of div tags, a label is a span tag.
I came from vb and asp classic and went to asp.net, and thought that all the elements on a webform has to be a asp.net object, but over the years, I learned how to better manage my time and produce consistent looking products by keeping asp.net objects to a minimum now.
I just use straight HTML now, and only use asp.net object for things like master pages, or anything I need to interact with in code behind on the server side. I never us the object font attributes or colors anymore, and use CSS for that.
In my opinion, don't get too crazy using the asp.net objects in the beginning, and just use html and CSS. As you start writing more code, then you can go back and convert some HTML to objects when needed.

we know that default session timeout is 20 minutes. so i just like to know if some one stay idle for 20 minute then session will be timeout?
if some one works for 20 minutes then session will not expire ? if will expire then when expire.
i hard that session has sliding expiration nature. can anyone tell me how sliding expiration works. is it default behaviour or developer has to set anything for club up this sliding expiration with session.
please discuss the internal of session nature & expiration. thanks

Pretty simple really. If the user doesn't re-access the application before the timeout, their session will expire. Theoretically as long as the user keeps accessing the app before the timeout, the "clock restarts" and the session would never expire, as soon as they wait until after the timeout their session will expire. It is also possible for the application to close the session if needed.

This is the default, you don't have to do anything extra.

suppose if user interact with my site for 20 minute does it mean that session will expire also after 20 minute if user interact?
if session will not expire then what will be the new session expire time?

If the user interacts within 20 mins, the session will not expire immediately. The session will last "forever" as long as they continue to interact less than every 20 minutes.
The session ends when:
1) The user fails to interact within the rolling 20 mins - it expires. (e.g. say the user logs in at 12:00, does something a 12:19, again at 12:38 and doesn't then interacts until 12:59 (21 minutes later).
2) The application closes the session programatically (e.g. logout).
3) Something crashes.

I've just said at lease twice, it won't.

Sorry, I cannot explain myself any more clearly. It will expire the next time the user fails to interact before the timeout limit, this could be the first 20 mins, the next 20 mins, the 20 mins after or so on.

I cannot know, it depends what you are doing and why. 20 minutes is just Microsoft's best guess. My bank expires the session after 10 to reduce the risk of CSRF attacks, but this would be unacceptably annoying for most other sites.

What have you tried so far? You have to be specific on what is troubling you.
To start with, follow the steps (for client side implementation - my preference):
1. Define a onclick button method A
2. In the method A, get textbox1 & textbox2 text. Now you know what needs to be replaced with what.
3. In the method A, get textbox3 text. You plan to replace textbox1 text to textbox2 text in this.
4. Define another method B, pass 3 parameters to it - fromText, toText, paraText
5. In method B, define a regex to replace in paraText - you got all the things you need
6. Once done, set the new text in the textbox3.
Try out!

Thanks for replying frnd., for example multiline textbox contain one para and the first textbox for find so i enter "is" and the second textbox for replace so i enter "are". when i click button, in the multiline textbox para has to change "are" wherever the word placed "is". i need coding for this using C#.

And I explained and shared the steps for exactly this.

It does not work like that here. You need to make some effort, try out and post specific issue if you face any. Please try the steps I shared.

Hello
how the convert asp.net ( Written in English ) to different other language.
|

I am personally not a developer. However, I am leading an application project from the business user design perspective. As a result, I am not sure which forum or forums this would best to post a question to, and guidance on that is certainly appreciated, but I selected this forum because I know the developer we are considering working with is using ASP.NET along with jQuery and ADO.Net.
Anyway, my question is, we were hoping to developing an input screen for financial statement line items (such as monthly revenue, monthly cash balances, etc.) that would appear as rows, with an input box for the current months data, and then alongside those input boxes would be one or more columns (i.e. by "columns" I mean visually on a grid/matrix chart like a column in an Excel spreadsheet) containing the same monthly data for prior months (and or sums of multiple months) drawn from fields previously input (or calculated) and saved in the database.
The developer we are talking with has come up with a tools that allows a next best solution in which the months appear as rows and the line items like revenue are columns. However, he is not aware of any tools allowing the webpage layout the original way I described which is simply inverted. I believe this developer is highly knowledgeable and experienced, but even people like that do not always know of everything out there, and given that plus my curiosity to learn knew things, enjoyment of research, the challenge, and ultimately the preference for having it set up the way we like, I figured that I would take a shot in the dark and ask if anyone either knows of a potentially suitable tool or solution, or if anyone might be able to point me in the right direction of someone else who might know where I can look.
Thanks in advance for any help and guidance and I appreciate your time in looking over my novice question.
Best regards

Well, it doesn't have to be something per-manufactured to do the job.
web pages are just made up of various HTML elements, that combined together, will get the job done, so it's a matter of writing something custom for you.
So take a grid view or treeview asp.net object, it's just a collection of HTML elements tied together, with some JavaScript to bond the functionality together for smooth operation.
ASP.Net is very robust, and you can do almost anything with it in ease. So your not making a mistake with the technology.
If it was me, I would of told you that it's a custom job, and it will take so many hours to develop, test and complete, and I would lose the contract because my price was too high.
For what's its worth, everybody thinks that you can just download something off the internet, paste and modify, and your done, but not the case.
Sounds like a Gridview job, and there are folks out there that just live in that control object. I don't, never used it, but there are thousands of people that specialize in it.
A gidview with textboxes for data input, click summit to generate the new data.
That's just my 2 cents of it.

I appreciate the guidance and feedback. I figured it must be possible as you suggest, and I don't view that he was saying it was impossible, but he indicated he really couldn't estimate what it would take. However, he apparently found some previously created tool or template he could use make the grid appear in the opposite direction. We don't have an unlimited budget, so probably a second best option much cheaper makes more sense. It just a little surprising to me more people wouldn't have developed something like that before.
Thanks again

I don't make it a practice to reuse code, unless I know that certain pieces of code will do the trick, because it's the same in functionality.
That's up to the creator, my years of experience says that if it's not the same thing, start from scratch and build it up.
As far as no one writing that, I sure it's been written already, someone doing government work or a corporate programmer writing for in house stuff.
Most people don't share code, except for scripts, which are a dime a dozen.
Based on your feedback, in which he has something that he can tweak, and can't give you a firm price, he must not be the author of the code, and does not fully understand how it works. So he may be easter egg hunting on how to customize it for you.
You really need to look for experience, most times it's cheaper, and you'll get a fine product the first time round.
