increase the the number of rows & columns I see

From some reason, I see only very few of rows and columns of my data Grid.
In order to see the rest, I need to scroll down and right.

The thing is that my screen still has enough space, both on the bottom and one right.

How do I fix this problem?

Thanks a lot!

What is height and width of grid container?

I’m not sure, I couldn’t find how to do it.

this is my basic initialization code:

ohh, o.k., i feel stupid - it’s in the style - now it works well…
thanks a lot…
