ToolTipController.DefaultController Property

Gets the default ToolTipController used for displaying tooltips.

Namespace: DevExpress.Utils

Assembly: DevExpress.Utils.v19.1.dll

Declaration

C#

public static ToolTipController DefaultController { get; }

VB.NET

Public Shared ReadOnly Property DefaultController As ToolTipController

Property Value

Type	Description
ToolTipController	A default ToolTipController object.

Remarks

Controls implementing the DevExpress.Utils.IToolTipControlClient interface provide the ToolTipController property of the ToolTipController class. When the control’s ToolTipController property is null (Nothing in Visual Basic), control’s tooltips are managed by the static default tooltip controller and this can be accessed via the DefaultController property.

If the control’s ToolTipController property is set to a ToolTipController object, the control’s tooltips are handled by this tooltip controller object instead of the default.

The default tooltip controller enables you to have similar looking hints for your controls. The default tooltip controller, however, can only be customized via code.

If you need some controls’ tooltips to look different or you want to customize the tooltip controller at design time, then you should create a ToolTipController component (by adding it onto the form, for instance), customize its settings and assign it to the ToolTipController properties of the appropriate controls.
