Visual Basic: Windows Controls
Expanded Property
Returns or sets a value that determines whether a Node object in a TreeView control is currently expanded or collapsed.
Syntax
object.Expanded[= boolean]
The Expanded property syntax has these parts:
| Part | Description |
| object | An object expression that evaluates to an object in the Applies To list. |
| boolean | A Boolean expression that specifies whether the node is expanded or collapsed. |
The settings for boolean are:
| Setting | Description |
| True | The Node is currently expanded. |
| False | The Node is currently collapsed. |
Remarks
You can use the Expanded property to programmatically expand a Node object. The following code has the same effect as double-clicking the first Node:
TreeView1.Nodes(1).Expanded = True
When a Node object is expanded, the Expand event is generated.
If a Node object has no child nodes, the property value is ignored.
