TdxCustomOrgChart.OnExpansion Event
In This Article
Occurs before the node expanding.
#Declaration
Delphi
property OnExpansion: TdxOcAllowEvent read; write;
#Remarks
Set the Allow parameter to False in the OnExpansion event handler to prevent expanding a node. The Sender parameter specifies the control that raised the event. Cast the parameter value to the TdxOrgChart or TdxDbOrgChart class to access the type-specific members.
Use the Node parameter to address the node, which is about to be expanded.
