Hi!

All that you aske for could be handled using _Assign and _Access methods. In the class designer you can check checkboxes 'Assign' and 'access' to add these methods or add them manually like 'PropertyName_Access'. These methods will be fired automatically each time something assigned to the property in code or something accessed (taken a value from property). This way, for example, you can forward assignment to the property to the real RecordSource property of the grid when value assigned to the property of container. You can make a checking for valid value of record source in the assign method and prohibit change if it is not valid (RecordSource of grid is character only and it is either alias, table or SQL Select statement).


>I am attempting to make my grid more generic and accept any recordsource. The grid is inside a container. (The container/grid and other controls are a class in my library) I would like to have the recordsource for the grid be specified by setting a property of the container. Then all other controls, in the container and the grid as well, can reference that property value. But I am having problems. I don't know when the record source is evaluated.
>Say for example that the container has the value: cursurques
>Dumb question: How does VFP evaluate whether a value in a property is character or numeric or a variable itself ? Shouldn't =somvar evalutate the variable,
>whereas something like cursurques evaluates to the string cursurques ?
