>>>>Good idea, George. It might be even easier to implement this idea in VFP 8 using BINDEVENT() function. Instead of creating separate _Assign methods one can bind the necessary properties to one custom check method, that fires whenever any bound property is changed and will validate all the properties.

>>>Nick,
>>>How do you go about binding properties? I would think you would still need an _ASSIGN for each property and then bind each _ASSIGN method to one custom check method. I'm not sure, in my mind, if this buys you anything other than adding a level of complexity (i.e. another method call).

>>No, if the property is bound to the method/event, VFP 8 does the implicit _ASSIGN for the property. Here is the sample similar to what I showed at my VFP 8 presentation in Chicago:

The possibilities of BINDEVENT() are HUGE...
