RepositoryItemTrackBar.BeforeShowValueToolTip Event

Allows you to provide custom tooltips for the thumb(s).

Namespace:DevExpress.XtraEditors.Repository
Assembly:DevExpress.XtraEditors.v17.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type DevExpress.XtraEditors.TrackBarValueToolTipEventArgs containing data related to this event.

Expanded Remarks

You can enable tooltips for the control's thumb(s) via the ShowValueToolTip property. By default, tooltips only display the current value. To provide custom tooltips for the thumb (for example, to format the value in a specific manner), handle the BeforeShowValueToolTip event. While handling this event, the custom tooltip must be assigned to the event's ShowArgs.ToolTip parameter.

Expanded Example

The following code shows how to implement custom tooltips for a TrackBarControl's thumb.

To enable tooltips, the ShowValueToolTip property is set to true. Custom tooltips are implemented via the TrackBarControl.BeforeShowValueToolTip event. The result is shown below:
