TreeNode.ToggleExpandState Method

Note: This method is new in the .NET Framework version 2.0.

Alternates between the expanded and collapsed state of the node.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public:
void ToggleExpandState ()
public void ToggleExpandState ()
public function ToggleExpandState ()

Use the ToggleExpandState method to alternate between an expanded and a collapsed state for the node. For example, if the node is collapsed, calling the ToggleExpandState method expands the node, and vice versa.

NoteNote

As an alternative, you can set the Expanded property directly.

The following code example demonstrates how to use the ToggleExpandState method to alternate between an expanded and a collapsed state for the root node of a TreeView control.
