How to repaint a Grid cell

created 21 years ago (modified 2 years ago)

Description:
I am using custom drawing to colorize the cells of a View in my Grid and they do not seem to repaint when I return from another form. How can I force them to be repainted?

Answer:
You may just call the Invalidate method of a View or a particular record:

Delphi
AView.Invalidate(False);  
AView.Controller.FocusedRecord.Invalidate;  
AView.Controller.FocusedRecord.Invalidate(AColumn);

Please refer to the ExpressQuantumGrid's documentation to learn more about these methods.
