Parameters

oItem

Type: TreeViewItem
The treeview item to be expanded.

lAll

Type: Logic
If lAll is TRUE(default = FALSE), the operation is done for the complete subtree of the specified item.

lForceNotify

Type: Logic
If lForceNotify is TRUE(default = FALSE), a notify message Window:TreeViewItemExpanding() and Window:TreeViewItemExpanded() is sent for each item whose expand state is changed. Generally windows will only send these messages when an item is first expanded. It depends on the TVIS_EXPANDEDONCE state. (see in Platform SDK the TVM_EXPAND Message for more details.)
