<TreeView>.ExpandAll (Function)

In french: <Arbre>.DérouleTout

Expands a node and all its child elements in a TreeView control.

Example of TreeView control:

Reminder: At runtime, a node is expanded when the node name is preceded by "-".

Example

// Expand the "Desserts" node in the "TREE_TVRecipe" TreeView control
// All child elements are also expanded
Res = TREE_TVRecipe.ExpandAll("Recipes" + TAB + "Desserts")

Syntax

<Result> = <TreeView control>.ExpandAll([<Node to expand>])

<Result>: Boolean

True if the node and its child elements have been expanded,
False otherwise.

<TreeView control>: Control name

Name of TreeView control to use.

<Node to expand>: Optional character string

Path of node to expand (as well as its child elements). This parameter has the following format:

"<Name of root>" + TAB + ["<Name of 1st node>" + TAB + ...
["<Name of 2nd node>" + TAB + [...]]]"<Leaf name>"

If this parameter is not specified, the TreeView control is expanded from the root.
In case of duplicates on a path element, this path can contain the element identifier (specified at the end of its name by TreeID).
