OK, I can see that you're not working for money, you're just writing code to teach yourself. You should at least look at putting your connection strings into the web config, although this code would still be a long way short of a commercial standard, even if you did that.
I don't see the BindData method, I assume that's the method you want to fill the drop list when the user is editing data ? You have code to fill the drop lists, why do you have a drop list if the item is not being edited ? And why do you read your data source every time, including for rows that are not item rows ?
As I said, a lot of work here. I think you may want to buy a book and work through it, and abandon this test project for now.

It's always amusing to me when people are rude enough to put a time limit on free help, don't post all the code needed to help them, and don't respond when people try to help.

I did help. I responded, and asked for more details, and made some comments. I assume you're doing some sort of self teaching project ? Why not just simplify it for now ?

But, this just binds the grid to the same data source it had to start with. How is that supposed to help fill any drop down list ?

I have the same questions about this mess as I did in my first post.

you know, every day, people who are obviously not qualified to write commercial code, post here about obviously commercial projects, and we're expect to offer our help for free on projects we can't get, because you've underbid us, obviously on the basis that you don't have the skills to work in this area, and therefore are happy to earn whatever you can get. Then when we answer you, we have to ask questions to try to get to the bottom of things, your code is so bad that we end up commenting on a lot of different things that need improvement, and when we get to the point where we've asked for more info so we can still try to offer you free help, although you're stealing from us, you cut the conversation short by saying something like 'ok thanks I got it....'. Do you really get that you're not able to write software for a client at this point ? Do you have any plans to learn ? Do you understand anything I said ?

Well, if you're doing paid work, then you need to stop. If you're doing work to learn, then yes, there's nothing wrong with that, but what you're trying to do right now is obviously far too complex for you.

It is not possible.
You can only access the things that comes from Request headers. You can only check IP address of the client. MAC address is not accessible.

You have to make every string in your program read from string tables, and set up string tables for different languages.

Do you have a bin directory ? What version of .NET are you using ? Does the message say that, even if you load the page in question ? Is the breakpoint in an actual page ?

Also check whether Terminal Service is Running.
Debugging requires Terminal Service. Check whether it is running or not.

In my page, while page load short description of some articles displayed. when i click the viewmore link the large description of the corresponding article is enabled. This div also has another one linkbutton for view comments. If first i click viewmore link means the large description is displayed.Next i click the viewcomments link means again the short description is displayed. I try to use updatepanel for this. but no solution.

You probably need to rephrase your question and explain what you are asking clearly.
