collapsable master detail gridview structure

Question

I need an advice for a c# asp.net project. My client wants to see some reports via the gridview object with master/detail structure.

The main gridview will be full by all master data and each row will have a + icon (or button) on the first cells. When user clicks this icon, the all details data of that master row should be seen under that master row with collaps action.

I can handle the database proccess but i can not figure out the collapsing part. How can i put some extra rows under the specific row on the gridview object?

Thanks in advance..

Matt Berseth has one of the most impresive tutorials on this kind'a stuff

it contains til now 28 tutorials only on the GridView plus a lot from other asp.net controls as well using jQuery with them. I do learn plenty with him. I really love his work and I just wanna share this with you, you might actually get some good and professional ideas from his code!
