Rows
ASPxGridView displays three types of rows.
Data Row
Data rows represent records in a data source. These rows are displayed one after another. Record values are arranged horizontally within them.
Group Row
If grouping is applied, ASPxGridView displays group rows. These rows separate data row groups. They can be expanded and collapsed to show and hide data rows that belong to a group.
To learn more, see Grouping.
Preview Row
Preview rows are non-editable rows that allow large memo fields or custom data to be displayed across all the columns within ASPxGridView.
