Remarks

Group rows are created automatically by GridData when the data is grouped by a column.
Group rows are inserted into collection (special index collection) of rows (GridData.GroupIndexCollection) and in addition build up a tree (GridData.RootNodes). GroupIndexCollection is a flat representation of the tree.

Instead of working with collection of GridDataItem objects (as it does the base GridDataRow class), a group row holds only one GridDataItem (DataItem), which corresponds to a column the data is grouped by.
For example, if we have {Name, Age, Comment} data structure and group by Age, GroupNode.DataItem will be set "Age" data - an entry with index 1 in GridDataRow.ItemCollection. When the GridData builds a group, it takes the appropriate GridDataItem from the first row to be added in a group (because if these rows are in the same group, they have identical data in columns they are grouped by).
