the Compact Framework datagrid only supports text-type cells out of the box.
Alex and some others (Paul Yao) have created nice samples where you rotate
different
edit controls on top of cells in the grid to achieve in - place editing.
if you need icons or checkboxes in a grid-like view, look at using the CF
ListView in small icon view or even better ListViewEx from www.OpenNETCF.org.
