Fires when a group header is clicked.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v24.1.dll
NuGet Package: DevExpress.Web
Declaration
Event Data
The HeaderClick event's data class is NavBarGroupCancelEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the command which raised an event should be canceled. |
| Group | Gets a group for which the event is fired. Inherited from NavBarGroupEventArgs. |
Remarks
Write a HeaderClick event handler to perform specific actions on the server side each time a group’s header is clicked within the navbar control. Note that this event fires immediately after the left mouse button is released. If the button is released when the mouse pointer is not over a header, the event doesn’t fire. You can use the event parameter’s properties to identify the group whose header is being clicked and cancel the execution of the command, if necessary.
