Expands items automatically while user types characters to search for a specific item.
A boolean expression that indicates whether the control expands items while user
types characters to search for items.
Use the ExpandOnSearch property to expand items while user
types characters to search for items using incremental search feature. Use the
AutoSearch property to enable or disable
incremental searching feature. Use the AutoSearch
property of the Column object to specify the
type of incremental searching being used within the column. The ExpandOnSearch
property has no effect when the AutoSearch property is False. For instance, if
the ExpandOnSearch property is True, the control fires the BeforeExpandItem
event for items that have the ItemHasChildren
property is True, when user types characters.
