public virtual Usual Expand(
	Usual symName = default,
	Usual lAll = default,
	Usual lForceNotify = default
)

Parameters

symName (Optional)

Type: Usual
The symbolic name of the tree view item to be expanded.

lAll (Optional)

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

lForceNotify (Optional)

Type: Usual
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.)
