Collapsing/Expanding a grid view row in a ASP.net Web form

[fraogongi]

I have implemented a grid view that that lists invoices in a linear fashion. However, i want to improve its functionality so that one can be able to expand and collapse the rows in order to view more details/infomation about the invoices. I've searched on the net but most of the solutions are not satisfying. Am using C# as code behind in MS Visual Studio 2005.

Help..... anyone......?

Thanks in advance!!

Add a template column to the gridview, put a repeater control in it, put a button in the repeaters empty template, When it's clicked bind the repeater to the additional data.
