Dear Swami, I have created this kind of form before: roundrect background and margins between 2 rows. For the background I used my own graphic. The background graphic if present is used by the datagrid library for hiliting the row. I removed it. And for magins, I used a row height upper than the height of my custom background. The margins between 2 rows are transparent, so I was able to see the card's background without doing something specific with the datagrid.
