    • Zip Code | 10,00 | 15,00
    • Zip Code | 10,00 | 15,00
  • Country
    • Zip Code | 10,00 | 15,00
    • Zip Code | 10,00 | 15,00

Thanks. Shivam

The DataGridView control does not support expandable/collapsible rows or nested tables. You will have to use a third party control to achieve this.

Alternatively, have a look at this article, which details how to subclass the existing control. This solution does not support databinding, however, which may limit its usefulness.

Looks like the download is no longer available (was first posted in 2006). I only have a heavily-modified version of the original code, so unfortunately I can't help further. I suggest you look into third party grid controls.
