Sture,
There's a lot of controls in that suite.
For now we only wrapped the Grid control, but you could do so much more.
Certainly the suite is not cheap, especially the first year it is a tad expensive.
The years afterwards are about 50% of that though.

However if you need all those features then it will be worth it, as it is impossible to build yourself for less unless you work for free.
BTW, I just now notice they also have a community license.

Perhaps that is something to pursue.
