I create an one webpage in asp.net all the time i am facing the following pbm how to rectify it..
if(ds.Tables[0].Rows.Count > 0)
Maybe you need to check that ds.Tables[0] exists first
If you are constantly checking on your pages to see if that dataset has a table with rows, I would think you would want to make some helper class to check that your dataset is not null, and that whatever tables have actual rows. Also you might want to think about moving these to typed datasets.

Is it possible to select the data using indexes without using select statement...
No, you can not, you have to use it anyway. You can use stored procedure and call them from asp.net but stored procedure would have select statement to get data from tables.

I want to do some statistical analysis with an ms-sql database for an aps.net application. What are the options as I don't see many built-in functions for my purpose? Thanks for any suggestions. Options that you actually use would be appreciated.
Check out MathDotNet, it can do pretty much anything you'd need.

I have added a new field to the standard aspnet_Membership table.
Now that it's added, how do i get or set this field by UserId?
Delete, plese.(5-8-2013)
You should not change default membership table . Instead use profile fields. Following articles will help .

I don't recommend to use the profile features due it have a way too dirty to store the data. Only if you need just one or two more fields, it may have sense.
Anyway, you need to attempt to document yourself a little more before ask this kind of questions...

asp.net mvc module wise approach or different controller and repository for each table approach is better?
Could you elaborate on your question? I think I understand... I like creating a repository for each table in a LINQ-to-SQL or entities model, for instance. I think that helps group together related logic.
HTH.
