What is Dynamic?
Adjective
(of a process or system) Characterized by constant change, activity, or progress.
Noun
A force that stimulates change or progress within a system or process.
So Dynamic can change. It is the opposite of being Static or Fixed.
In VFP Grid, there is only one real row and the rest are just mirrors of the first one manipulated by VFP to show different values. It means that conditions on objects (textbox, combobox, checkbox, etc) on a column are static. What condition and formatting you applied to an object of a cell applies to the rest of the cells belonging to that column.
But since there definitely is a need for us to reflect on a cell certain values based on several conditions, then that is where Dynamic Properties of a grid is needed (see VFP help on available Dynamic Properties). A very powerful feature of grid that makes me prefer it over to listbox.
Yesterday inside Foxite, I finally understood the need of a fellow member with the sample he provided which is allowing a combobox inside a column to change values or sort of being filtered based on a combination of values of two fields (or column1 and Column5). And I showed him how to attain that by employing DynamicCurrentControl Property of the grid.
What is DynamicCurrentControl?
