BaseListBoxControl.ContextButtonValueChanged Event

Fires when the CheckContextButton.Checked, TrackBarContextButton.Value or RatingContextButton.Rating property value changes.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v23.2.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

[DXCategory("Behavior")]
public event ContextButtonValueChangedEventHandler ContextButtonValueChanged

VB.NET

<DXCategory("Behavior")>
Public Event ContextButtonValueChanged As ContextButtonValueChangedEventHandler

Event Data

The ContextButtonValueChanged event's data class is DevExpress.Utils.ContextButtonValueEventArgs.

Remarks

For context buttons (see BaseListBoxControl.ContextButtons) displayed in the current BaseListBoxControl, the ContextButtonValueChanged event fires when:

• the checked state of a CheckContextButton is changed (the CheckContextButton.Checked property value is changed);
• the track value of a TrackBarContextButton is changed (the TrackBarContextButton.Value property value is changed);
• the rating value of a RatingContextButton is changed (the RatingContextButton.Rating property value is changed).

The Item property of the ContextButtonValueEventArgs object, passed to the event handler, allows you to determine the context item whose value is changed. The Value property gets the new item value.
