What happens when u try to update data in a dataset in .NET while the
record is already deleted in SQL SERVER as backend?
OR What is concurrency? How will you avoid concurrency when dealing with
dataset? (One user deleted one row after that another user through his
dataset was trying to update same row. What will happen? How will you
avoid the problem?)

I would implement record locking so that one user at a time had the right to edit a piece of data.

iam working on one web application i have this error when i go from one page to other
Microsoft JScript runtime error: Sys.ArgumentTypeException: Object of type 'Sys._Application' cannot be converted to type 'Sys._Application'.
Parameter name: instance
plz give me solution for this why this is coming
iam using .net 3.5,ajax.

I would guess that you're not using AJAX at all, you're using ASP.NET AJAX, which is a wrapper for people who don't need performance and who can't be bothered learning AJAX for themselves.
You should be able to set into your debugger to see what line is causing the error. If it's deep in the framework you have no control over, then read the documentation, or google the error message, I'm sure someone else has solved it already.

The drop down control does not support this, but you could do it by faking your own control using a fixed size scrolling div.

You 'need to' ? Does that mean you've accepted work and have no idea how to do it ?
I suggest you do some reading on what ASP.NET is, and does. Then you'll understand why this is not possible using ASP.NET. It's probably possible using some sort of ActiveX control, which ASP.NET can host, but no-one is going to write that for you.

I know that app_offline.htm is a nice feature to stop asp.net web application. But lately, a number of my applications IN DEVELOPMENT suddenly have this file which I did not add them. When I tried to run an app in Visual studio 2008, I got the message telling me to delete this file. Does anyone know how this file is added? I could accidentally click something not knowing what.

AFAIK, this file will not get added automatically.
|
|
|
|
|
It suddenly appeared in a few applications which I knew I did not add manually. I do not even know where the original file is saved. I think it comes from either Framework or Visual studio installation.

It is generated when you are Publishing a website, it is usually deleted after the Publish has completed.

Why doesn't this form retain the values when I key them in the textbox? I've tried with Mozilla and IE.

This is the ASP.NET forum. You've posted HTML. HTML is client side only, there is no mechanism there for saving state. I suggest you buy a book on ASP.NET and work through it.
