NavBarControl.CustomDrawGroupClientForeground Event

Provides the ability to perform custom painting of a group client area's foreground.

Namespace:DevExpress.XtraNavBar
Assembly:DevExpress.XtraNavBar.v17.1.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 CustomDrawGroupClientForeground event handler to perform custom painting of a group client area's foreground. Set the CustomDrawObjectEventArgs.Handled property of the event parameter to true to disable default painting. Other properties of the event parameter allow you to identify the group whose client area is painted and provide all necessary information to paint it.

Use the CustomDrawGroupClientForeground event when you want to draw a group client area over the default painted background. If you don't want default background painting, use the CustomDrawGroupClientBackground event instead.

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 CustomDrawGroupClientForeground event to custom paint the text on a group's client foreground. The group doesn't contain any links initially and thus the NavBarGroup.CalcGroupClientHeight event is handled to specify the group's height.

The image below shows the result.
