Listgrid with more columns selections

[MirceaM]

Hi guys,
I'm pretty new with the smartClient and i wonder if there's any properties on listGrid/listgridFields which can do the same thing as the property on listGrid

setSelectionType(SelectionStyle.SIMPLE);

not only for a column "select" but for more,or even all.And i need the checkboxes from the header to keep the count for all the column (to be selected or not depending on the records).
I've attached a picture of the listgrid.
Thanks in advance.

You can either:

1. use canSelectCells. Selected cells will change background color as with normal selection

2. use columns of type "boolean" with canToggle:true. Boolean columns render as checkboxes by default, and setting canToggle:true means you can change the value with one click.
