[System.ComponentModel.Category("Action")]
[System.ComponentModel.Description("Occurs when the active tab is about to change.")]
public: __event ActiveTabChangingEventHandler* ActiveTabChanging

[System.ComponentModel.Category("Action")]
[System.ComponentModel.Description("Occurs when the active tab is about to change.")]
