Selecting a tree node and navigating the tree

You can select a tree node in the TreeView DataWindow in the
following ways:

Use the SelectTreeNode method
to select a tree node.
Set the Select Node By Mouse property to true and
then click a tree node to select it with the mouse.

After you select a tree node in the TreeView DataWindow, you
can navigate the tree using the up, down, left, and right keys.

Use this key	To do this
Up	Select a tree node prior to the currently selected node.
Down	Select a tree node next to the currently selected node.
Left	Collapse the currently selected node. If the current tree node is a leaf node or the node has been collapsed, the DataWindow just scrolls to the left, which is its normal behavior.
Right	Expand the currently selected node. If the current tree node is a leaf node or the node has been expanded, the DataWindow just scrolls to the right, which is its normal behavior.

For detailed information about TreeView DataWindow properties,
methods and events, see the DataWindow Reference
or
the online Help.
