ASP.net DataGrid with LinkButton

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance



Hello...
I would like to be able to do the following using VB.net & OleDb for Access
2003:
1)My first issue: When i click a linkbutton(located on the far right of the
datagrid), i need to be able to retrieve the value of a primary key for that
corresponding row. That primary key will be either a textbox or it can be a
regular bound column field.

2) My second issue will be the need to download a file into a "NEW" browser
window so that the currently displayed datagrid remains intact! Once the
primary key value hs been retrieved, from the above request, i intend to pass
this primary key value into a standard select statement to retrieve uploaded
files currently located in a MS Access 2003 database table. This downloading
of the files will be for viewing purposes only.

3)My final request will be concerning passing the values from the selected
rows in the datagrid, using a 2nd linkbutton located on the far left, into
another table of the database along with the previously viewed file. I
suspect this is a simple download from one table to another in the database.

Thank you in advance for your help!!

Sincerely,
