I have a web form in vb that I am writing and I am stuck on getting th evalue of one cell in a row when the checkbox is checked so that I can insert that value into a table in an access database.
Can anybody help on this?
I have spent a couple of days on this already and have gotten nowhere. I have looked at dozens of examples and a few tutorials, but nothing works.

I have this basically working, but I have some issues that I am still working on here. There are five columns in the table that need to be updated. With the current statement, I get an error:

Number of query values and destination fields are not the same.

I need to have a minimum of 1 and a maximum of 5 checkboxes checked to update the database. I have not been able to get an update statement to function correctly - I am just doing something wrong, but not sure what.
Can anyone help with the gridview checkbox validation and with the sql update statement?
Thanks in advance

exception says you supplying less number of parameters..

please map your parameter correctly while writing a query..


Thank you. The gridview code is posted below.
DNANetwork - that is the problem - I apparently do not know how to write it correctly. That is why I am asking for help. Can you give me an example?
