CustomDrawEventArgs.Handled Property

Gets or sets a value specifying whether an event was handled and that the default element painting is therefore not required.

Namespace:DevExpress.XtraTreeList
Assembly:DevExpress.XtraTreeList.v19.1.dll

Expanded Syntax

Property value

Type: Boolean
true, if the default element painting is not required; otherwise, false.

Expanded Remarks

If custom drawing is implemented and the Handled property value remains set to false, all the custom drawing performed will be overwritten by the default painting mechanism using the appearance settings. These appearance settings are specified by the Appearance property.

Set the Handled property to true to prevent the default painting mechanism from clearing any custom drawing after a custom draw event handler has been completed.

The DefaultDraw method, when called, automatically sets the Handled property to true.
