A simple google search should get you tons and tons of examples.

See http://stackoverflow.com/questions/18482132/how-to-bind-check-box-values-on-gridview-with-the-values-of-database-table[^] for an example.

Hey, please see that Field is not Bit Type so that i can bind data directly.I cant use Eval here.Field is of int Type (ID) .Suppose an student has given many exam ID from options and then I save into database.After then when he returns on same page he must display which exam ID he has selected.How to achieve this?

In your SQL, you need to return the proper value for each column.

how?pl give me example if i have column having integer value inserted into table and then I have to display acc to this data against default gridview row

It's your data so I can't tell you how.

However, perhaps something like

CASE WHEN field1 > 3 THEN 1 ELSE 0 END AS field1, etc, etc.
