It worked. Thank you.
But is a strange behavior nevertheless.
Why other components work in some way and this doesn't?
Also I recommend you guys to check out the demo and documentation.
Pivot for example is quite slow in some of when filtering.
And it´s quite hard to learn how to do a lot of stuff without examples for all the methods.
I'm the front-end in charge of testing this in the company I'm working on,
but the idea is to buy the full version soon and most of my back end colleagues will have problems.
Devexpress, which was used here, has a far better documentation, even tho you guys have the best product.
Thanks again, and great work.
