Cascading style sheets(CSS) can help you define a general style for the entire datagrid (which you discovered below) but also to specify individual columns' styles by specifying a cssClass for each DataBoundColumn by setting properties such as HeaderStyle-cssClass and ItemStyle-CssClass.This is an example where the textbox size, the background-color and the font is different for each column that overrides the default cssClass settings for the datagrid
