Toggle GridView row

[Chetan Garude]

Wondering if I can toggle GridView rows without Javascipt or have
minimal Javascript? Here's the situation, crank your brains and output
your ideas...

1. I have a Gridview with every row containing a hyperlink column. Based
on the click for the hyperlink column, I need to dynamically insert
another row EXACTLY BELOW it, which is editable.

2. This row must have a Edit/Update/Cancel button in it and the columns
must be editable.

3. Clicking on the same hyperlink column must hide(toggle) the
visibility of the inserted row.

Question is can this be managed with server side scripting?
Thanks. Ideas welcome...
Chetan.
