ActionBase.CustomizeControl Event

Do not handle this event for a built-in Action in a View or Window Controller's OnActivated method because this method is called after the Action controls creation. Use the OnFrameAssigned method instead.

The CustomizeControlEventArgs.Control event parameter returns the Action Item object which provides access to the control settings. See all of the possible scenarios in the Action section of the Feature Center demo that is installed in the %PUBLIC%\Documents\DevExpress Demos 18.2\Components\eXpressApp Framework\FeatureCenter folder by default, or refer to the Feature Center demo online. The lists below show which type of Action Item is returned for different Action types.
