• TreeList.CustomDrawNodeIndicator

Remarks

The TreeList.CustomDrawNodeIndicator event gives you the ability to paint indicator cells using custom draw. The basic information required to perform custom painting is provided by CustomDrawNodeIndicatorEventArgs class properties inherited from the CustomDrawEventArgs class. These properties allow you to obtain indicator cell specific information, such as the type of element for which an indicator cell is displayed (either a node or a row footer), the corresponding node, etc.

Objects of type CustomDrawNodeIndicatorEventArgs are automatically created, modified and transmitted to TreeList.CustomDrawNodeIndicator event handlers.
