What's the difference? When to use one and when to use the other?

I like GridCtrl for:
simple API;
cells structure;
header cells as standard cells;
may have any Display for header cells;
it have nice mini-toolbar (very customized),

But forum say, that ArrayCtrl is little bit faster.
and ArrayCtrl have full documentation.

PS
Maybe ArrayCtrl is have same features, but it's API is not transparent. Not same as in GridCtrl.

Take a look at: http://digitalsoftware.pl/dgs.php?page=upp&sub=grid
In the beginning ArrayCtrl had less features than today. I decided to write my own control then but even now it has more features that ArrayCtrl. The only noticeable difference is lack of virtual rows in gridctrl. Inside grid is simply a Vector<Vector<Value>> and grid ctrl is quite well optimized to display it. ArrayCtrl can be faster if you use conveners for columns because it uses some kind of cache. However in most cases I had never performance issues (even if I loaded 500.000 rows on my athlon x2 machine.
And that's true that documentation is poor. There is few features nobody knows about because of that. I have to fix it Smile

I can write in Russian. Then we need to edit and translate.

Hello Sergey

I prefer to use GridCtrl... but when using very big data sets and when I need to include full controls inside rows.

I believe it is possible to set custom Display, Converter, e.t.c. only for a column with ArrayCtrl. In case of GridCtrl you can do that for a particular cell.

I can be wrong.

Problem is in that: I can translate to English existing text, but writing new request more deep English. Therefore I propose to write in Russian, and anybody translate this.
