Visible: Boolean;
The Visible property determines whether a component is displayed during form execution.
If the property is set to False, the component becomes invisible. If the Visible property is set to False (True) for the parent component-container, all child elements become invisible (visible) together with the component-container. With the help of this property it is possible to place several components that correspond to the different modes of form work, on the same place of container and make visible necessary component at the necessary time.
