§ tag() [2/2]

virtual control& xtd::forms::control::tag ( std::any  tag)

Sets the object that contains data about the control.

tagA std::any that contains data about the control. The default is empty.
Any type of class can be assigned to this property.
A common use for the tag property is to store data that is closely associated with the control. For example, if you have a control that displays information about a customer, you might store a data_set that contains the customer's order history in that control's tag property so the data can be accessed quickly.
