Error handling can be done on Page Level, by overriding the onerror() function.
Can this be done only on master page ?
I mean, can we add an error handler on master page, rather than adding it on every single page ... ???

I am not sure that this is true. But, you can handle errors at the top level in the same place that the application start and session start events are handled.

your question makes absolutely no sense. 'every time you run the application' ? If you mean every time you do a postback, then the other answer you got is correct. If you mean what you said, what did you expect it to show ? If you want to show something else, then you need to set the selected index. Perhaps if you explain yourself better.

I am astounded by the constant stream of people stupid enough to think that an entire web page reloading whenever they press a key, is a good idea.
You can handle a javascript event which will fire whenever a key is pressed. You can then write AJAX code to do this check if you want to. I think it's a dumb idea. What if what they have typed half way through exists, but they want to type some more ?

So if they cannot write their own JavaScript methods and being able to handle the callback of the webservices, maybe is better to do a whole postback... (very sad... but true).
having said that... that's what (and how) I would do (following Christian approach)
I would recommend you write your own javascript handler and call a webservice using the microsoft AJAX wrapper.

Are you checking the value on postback, or on the first load of the page ?

You post here a lot to not know anything about how ASP.NET works. You should buy a good book and read it.
When your page is rendered, it's because it's been delivered the HTML to render it., Which means that ASP.NET has already run the full page lifecycle, and generated the HTML. I don't see how else it could work, or why you'd think it would work differently. What you want to do is impossible. You want the onload event to fill a property, before your code has generated the page.

When the asp.net page load then first it execute the code in .cs file and then it
execute the javascript function. so i got "" in my hidden field value.
n i know about asp.net page life cycle..

Yes, that's right. So, there's no way you can read it in your page load, for the first cycle, because, as you said, it gets read into the hidden field AFTER the page has run on the client side.

I am using System.Windows.Forms
OpenFileDialog ofd=new OpenFileDialog();
Thread sd=new Thread(new ThreadStart(()=>ofd.showDialog()));
sd.SetApartmentState(ApartmentState.STA);
sd.Start();
sd.Join();
It displays OpenFileDialog but it goes behind browser window how to bring front

Then why are you asking in the ASP.NET forum ?

Seriously, I looked, and every one of your posts has at least two of the following things in common
1 - the subject says 'please help me' instead of something useful ( every post does this )
2 - you post in the wrong forums ( I found an ASP.NET question in the managed C++ forum )
3 - you have no idea what you're doing
I find it very frustrating to try to help people who not only are as dumb as toast, but who don't answer when I try to help them. The answer is, you have no idea what you're doing. You're plainly trying to use an openfiledialog in a web page ( I worked that out for sure from an earlier question ). This makes you utterly clueless, and I only hope you're teaching yourself. If you have a teacher, he is a failure. If you are doing paid work, you are a liar and a thief, because you don't come close to knowing enough about what you're doing to write anything to even a semi professional standard.

I've got IIS 5.1 installed and at the root there is index.html that can be accessed from the internet.
When I put to the root VS2008 web project application (e.g. just simple with single button click, that works for sure) the server returns:
Server Application Unavailable
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request
The default.aspx is specified in the list of default files.
