Jim Lynn discusses
how to change the background of each grid row.
I just had to implement a design where a table of data, in Silverlight, had to have cell backgrounds where each cell is slightly darker than the cell above. [...]
The simple way is to just put in a border or background rectangle into each cell. This is what I did originally. But it’s a lot of work no matter how you do it. Neither Blend nor Visual Studio lend themselves to this kind of thing, and even hand-editing the Xaml can lead to cut&paste errors.
