CalendarControlBase.CustomContextButtonToolTip Event

Namespace: DevExpress.XtraEditors.Controls

Assembly: DevExpress.XtraEditors.v24.1.dll

NuGet Package: DevExpress.Win.Navigation


public event ContextButtonToolTipEventHandler CustomContextButtonToolTip

Event Data

The CustomContextButtonToolTip event's data class is DevExpress.Utils.ContextButtonToolTipEventArgs.


Use a context button’s SuperTip property to assign a super tooltip to the button. To assign a regular tooltip, use the following properties:

  • ToolTip — gets or sets the tooltip text.
  • ToolTipTitle — gets or sets the title displayed above the text.
  • ToolTipIconType — gets or sets the icon that indicates whether the tooltip contains an error, warning, question, or other information.

See the following topic for more information about regular and super tooltips: Hints and Tooltips.

Rating Scale and Track Bar

The RatingContextButton and TrackBarContextButton show the current rating and track value in the default tooltips.


You can handle the owner control’s CustomContextButtonToolTip or the button’s CustomToolTip event to specify custom tooltips. Use the Value event argument to obtain the current value and the Text event argument to specify the tooltip text.


The owner control’s CustomContextButtonToolTip event fires after the button’s CustomToolTip event and overrides its tooltips. Also note that these events do not fire if a super or regular tooltip is assigned to the button.

Disable Tooltips

You can also disable the owner control’s ShowToolTips option to hide tooltips. The button’s ShowToolTips property overrides this option for an individual button.


pictureEdit1.Properties.ContextButtonOptions.ShowToolTips = false;


If a context button’s Enabled property is set to false, tooltips are not displayed regardless of the owner control’s ShowToolTips option or the button’s ShowToolTips property.
