The Grid dashboard item allows you to specify various style settings.
To do this, use the Style group in the Design Ribbon tab of the Grid Tools contextual tab set.
The Horizontal Lines and Vertical Lines buttons control grid line visibility.
To paint the background of odd and even rows differently, use the Banded Rows button.
Note that banded rows are not available when cell merging is enabled.
In code, use the GridOptions.EnableBandedRows property.
