Public Event ExpandButtonClicked As EventHandler(Of NodeEventArgs) |
ExpandButtonClicked event handlers receive an argument of type NodeEventArgs. The following NodeEventArgs members provide information relevant to the event:
Member name | Description |
---|---|
The DiagramNode whose [±] button has been clicked. |
This event is raised only if ExpandButtonAction is set to RaiseEvents. Otherwise either the TreeCollapsed or TreeExpanded event is raised, depending on the state of the node.
The following sample code hides or shows all subordinated nodes in a group when the master node's [±] button is clicked:
