XtraTabControl.HeaderButtonClick Event

Occurs when a built-in header button is clicked.

Namespace:DevExpress.XtraTab
Assembly:DevExpress.XtraEditors.v19.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type HeaderButtonEventArgs containing data related to this event.

The following HeaderButtonEventArgs properties provide information specific to this event.
Property Description
ActivePage Gets an active tab page within the tab control.
Button Gets the currently processed header button.
Handled Gets or sets whether the HeaderButtonClick event has been handled, and no default processing is required.

Expanded Remarks

The tab control has the built-in Next, Prev and Close header buttons (see the HeaderButtons topic). The Next and Prev buttons have default processed actions (switching an active tab to next or previous). By default, the Close button has no default action. To implement a default action for the Close button, use the CloseButtonClick event.

You can override default actions for the built-in header buttons by handling the HeaderButtonClick event. When handling the HeaderButtonClick event, you need to set the HeaderButtonEventArgs.Handled property to true, to prevent a button's default action from being invoked after your event handler call.

You can also add custom header buttons to a tab control via the CustomHeaderButtons property.
