Suppose you display a data having 200 records in a
datagrid. Then you edit 100 records of them. Now when you
will press update button,all 100 records should be updated
in single shot rather than reading every record and
updating. How to do it?

Answer Posted / pradeep
Each row is having Edit/Update/Cancel button.
In "_UpdateCommand" event, we can write a code to update
directly into the database. But it is not good practice.
For updating whole records in a single event, we need to
have hidden column for updateflag and while updating we can
store the updated data into session. By using BUTTON
control out side of datagrid, we can find only 100 records
(updated records) based on updateflag and we can update
only those records into DB.
