I think the question refers to the ability to specify an Alternate Row color, similar to the .NET 2.0 DataGridView control. That control allows an Alternate Row color to be set, as well as a default row color. The row background color then alternates with each row.
In other words, Row 0 has a white background, Row 1 has a gray background, Row 2 has a white background, Row 3 has a gray background, etc...
I know that you can set cell styles, but I also have the same question as the orginal post -- can the alternating row colors be set without a lot of code to dynamically determine whether the row is odd or even?
