Saving records in session to database.

hi,

I'm using vb.net and sql server and ado.net. I need a datatable in order to add in records from textbox. I didnt want to retreive any records from the database. Its simply a datatable, when a user clicks on ADD button, the values typed in all textboxes will be saved in the datatable then from there users can carry on adding till they are done and the datatable will show all records added in the datatable disconnected from the database. then all these records are saved in a session. Finally when the user clicks on Update then the records will be added/inserted into the database. Hope i managed to explain myself. and hope that help is given. thanks!!!
