Editable hidden row and write-back to SQL server

Hi All,

New to Datatables but just switched from Gridview and absolutely love them - i'm restricted to developing in vb.net so i have a question RE: hidden rows.

My page is loading as follows:

I have an aspx.vb file with a class _Default with a bunch of properties that instantiates on Page_Load and sucks out the data from a MS SQL server. I then load them into an asp repeater using Evals to load the data into rows - then loading that into a Datatable.

So that's all great - BUT - I have a hidden rows (using the great examples on this site) and although I can load content into the hidden rows no problem using hidden columns - i have no idea how to write any changes to the data in the hidden rows ie. a textboxs containing string, BACK to the SQL server upon fnClose() or a "save" button in the hidden row???

Some direction would be great ... unfortunately no JSON on our MS SQL server.
