isEmpty method

[ekomrak]

Could you add the following method to the GridCrud class?

public boolean isEmpty() {
    return CollectionUtils.isEmpty(items);
}

It will be very usefull method to do some logic if grid is empty.

Sure, would you like to add it yourself and send a Pull Request? That way you'd become a contributor to this project :)

Closing this since you can get the size of the underlying data provider as follows: crud.getGrid().getDataProvider().size(new Query<>()).
