TcxCustomVirtualTreeList.OnSetNodeValue Event

In This Article

Enables you to control data writing to the custom data source.

#Declaration

Delphi
property OnSetNodeValue: TcxVirtualTreeListNodeValueEvent read; write;

#Remarks

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

Implementation of the event handler is an alternative way of overriding the TcxTreeListCustomDataSource‘s SetValue 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 sent to the data source.
