DbGrid: it's just me or disabling "custmizablecells" is really much faster?

Don't know. Actually it must have little effect if you don't use

OnDrawColumnCell event. Maybe in mobile devices it will have some

significant changes. What browser are testing?

I see a significant speed-up with IExplorer 8 on dbgrid with 200 row.

Now the more slow browser is Mozilla Firefox.

Tested on Atom netpc.

Thanks for feedback.

 

Consider below scenarios:

 

1) Grid with CustomizableCells=True, but no custom column color and no

OnDrawColumnCell event assigned.

 

2) Grid with CustomizableCells=False.

 

Is there any speed differences between above two scenarios? In my PC the

difference is intangible.

 

In my tests slowing starts only when you actually start coloring cells

either using TColumn.Color or in OnDrawColumnCell event.
