TcxCustomVirtualTreeList.OnGetNodeValue Event

Enables you to control data reading from the custom data source.

Declaration

delphi

property OnGetNodeValue: TcxVirtualTreeListNodeValueEvent read; write;

Handle the OnGetNodeValue event if the TcxTreeListCustomDataSource‘s descendant is not implemented.

Implementation of the event handler is an alternative way of overriding the TcxTreeListCustomDataSource‘s GetValue method, and is applicable if the built-in TcxTreeListCustomDataSource is used (see the Introduction To Provider Mode help topic).

Sender specifies the tree list.

ANode and AColumn specify the data cell whose content is being handled.

AValue specifies the value to be obtained from the data source.
