Solution 1

Use max in your sql, and the data will be in a column and show in your grid.

Select max(x) from y

The answer then is to fix your SQL so the value is what you want

please explain clearly

It doesn't get any clearer. Your column contains the data you asked for. Ask for the data you need. Don't ask this again, the answer won't change. If you don't know SQL, post your SQL, your table structure, and details of what you need and hope someone here does your job for you

data base like this

id code qty osno
1 2 10 1
2 3 10 2
3 4 10 3
4 6 10 4
5 7 10 4

my question is to get max of osno value should show in a gridview as separate column
as well as the database also

i need gridview like this to show an output

id code qty osno max no
1 2 10 1 4
2 3 10 2 4
3 4 10 3 4
4 6 10 4 4
5 7 10 4 4

So what is the issue ? You just need to do what I said. You didn't post your SQL, but this is so trivial, I don't see why you couldn't do it from my first answer.

Select id, code, qty, osno, max(osno) as max_no from myTable.
