Public Event ActiveTabChanging As BootstrapTabControlCancelEventHandler
The ActiveTabChanging event's data class is BootstrapTabControlCancelEventArgs. The following properties provide information specific to this event:
|Cancel||Gets or sets a value indicating whether the command which raised an event should be canceled. Inherited from TabControlCancelEventArgs.|
|Tab||Gets a tab object related to the event.|
Write a ActiveTabChanging event handler to perform specific actions on the server side before each time the selected tab changes. You can use the event parameter’s properties to identify the newly selected tab and cancel the execution of the command if necessary.
