Hank,

Good point. I merged today my class and vpmctrls.vcx class, which I guess was an error. On the other hand, if I would merge my class with grid_ in proctrls, then grid_toolbar would not inherit it, since it's a subclass of devctrls.vcx grid_

Or should I have merged grid_ in proctrls with my class and then redefine grid_toolbar to be based on grid_ from proctrls? What about grid_list - do we need it here or it's already built-in (I think it's built-in)?

I can probably revert my today's changes and try to change proctrls

Unfortunately, I faced the problem today - the working form (which is really very delicate form - one minor change and it starts breaking apart - it uses buffering 3 and set filters based on public variables in Activate) broke down - looks like I can not use my grid class with it or will have to disable sorting.

BTW, what do you think about incorporating native sorting abilities in base framework grid? It sounds like a common requirement - the only problem that existing apps can break - I guess by default the sorting should be disabled then.

>>UPDATE. I hacked the grid and combined them both in VPMCtrls grid_ class. Going to test in a moment.
