Public Event HideCustomizationForm As EventHandler
The HideCustomizationForm event's data class is EventArgs.
You can hide the Customization Form by calling the TreeList.HideCustomization method. End-users can also close the form manually. In both cases, the HideCustomizationForm event is raised. Write a handler for this event to perform specific actions in response to closing the Customization Form. This can be used, for instance, to hide instructions on using the Customization Form, that were displayed when the Customization Form first appeared. Use the TreeList.ShowCustomizationForm event to perform specific actions when it becomes visible.
