By default, the ItemHasChidren property is False. Use the ItemHasChildren
property to build a virtual grid. Use the ViewItemStateStartChanging(exExpandItem)
event to add new child items to the expanded item. Use the ItemChild
property to get the first child item, if exists. Use the ItemChild or ChildCount
property to determine whether an item contains child items. The control
displays a +/- sign to parent items, if the HasButtons
property is not empty, the ItemChild property is not empty, or the
ItemHasChildren property is True. Use the InsertItem
method to insert a new child item. Use the CellData
or ItemData property to assign an extra value
to a cell or to an item.
