It will be very good if you add property to the grid

It will be very good if you add property to the grid, because it is comfortable use hidden fields,
by the way I read in your knowledge base that function  setColumnHidden  works slowly.

P.S. I see js error:
mygrid.setColumnHidden is not a function
[Break on this error] mygrid.setColumnHidden(1);

>>P.S. I see js error: mygrid.setColumnHidden is not a function
Which version of grid you are using ? The setColumnHidden method  available only in pro version.
