It's better to insert a record while reading rows from GridView. Of course you can choose stored-procedure or parameterized query.

First, you should optimize the query as it seems slow and thats why you are getting this exception. Second, you can increase the command timeout to infinite to overcome this exception.

command.CommandTimeout=0;
