Grid-MultiSelect without checkboxes

Hi!
I have a Grid with selection mode Multi, by default this adds a column with checkbox. I dont want those checkbox for multi select. I want If user clicks on the row itself and while pressing control, it should perform multi selection.

Is there anyway possible with Grid to have multi select without a extra checkbox column. Please provide some solution for this.

Ps. Maybe there is somewhere a defined template in .html that could be change? Anyone know something about it?

Yes, I would like to know that too.

Another annoy one is that in Multiple selection mode, how can I select whole row instead of a cell while the editor is disabled?

Thanks!
