NavBarControl.CustomDrawBackground Event

Provides the capability to custom paint the control's background.

Namespace:DevExpress.XtraNavBar
Assembly:DevExpress.XtraNavBar.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type CustomDrawObjectEventArgs containing data related to this event.

The following CustomDrawObjectEventArgs properties provide information specific to this event.
Property Description
Appearance Gets the painted element's appearance settings.
Cache Gets an object which specifies the storage for the most used pens, fonts and brushes.
Graphics Gets an object used to paint the object.
Handled Gets or sets a value specifying whether the control must perform default painting after an event handler has been executed.
ObjectInfo Gets an object providing information on the element being painted.
RealBounds Gets the bounding rectangle of the painted object.

Expanded Remarks

Write a CustomDrawBackground event handler to perform custom painting of the control's background. Set the CustomDrawObjectEventArgs.Handled property of the event parameter to true to disable default background painting. Other event parameters provide you with all the necessary information to perform background painting.

Group captions and client areas occupy the entire control's area in certain paint styles. Writing a CustomDrawBackground event has no impact in such a case.

Note

The control's events designed to change the appearance or rendering of control elements must not be used to update cell values or to modify the control's layout. Any inappropriate operation which causes a layout update, may break the normal control behavior.

Expanded Example

The following sample code handles the CustomDrawBackground event to fill the XtraNavBarControl's background with a linear gradient brush and draw a string at the bottom.

The image below shows the result.
