GridItem

---

System. Windows .Forms (system. windows .forms.dll)

abstract class

This class represents a particular row in a PropertyGrid and is used in the PropertyGrid.SelectedGridItem and PropertyGrid.SelectedGridItemChanged members .

You can discover whether the row is Expandable (and whether it is Expanded ), which GridItems are children of this one, and which is its Parent .

The Label and Value can be retrieved (but not set) through those properties, and you can also retrieve the PropertyDescriptor for the item, to discover what type the item Value might be and which System.ComponentModel.TypeConverter is available for it.

The Select() method causes the row represented by this object to be selected in the PropertyGrid .

The GridItemType property is used to determine whether this row in the grid represents an ArrayValue , a Category line (e.g., the Behavior, Layout labels), a simple Property , or a Root item for an expandable row.
