unselect the check box on the selector

is there a way to unselect the check box on the selector through javascript code

i use
obj.setSelectorVisible(true)
obj.setSelectorWidth(30);
obj.setSelectorTemplate(new AW.Templates.CheckedItem);
to get the checkbox on selector

after i click on some icon depending upon conditon i want to uncheck the checkbox
how to attain this?

Just clear selected rows -

obj.setSelectedRows([]);

thanks Alex....

to dig a bit deep into it
i wish to deselect all previous selections on click of an icon

it seems
obj.getSelectorTemplate(row_num).refresh();
where row_num is the number of row
this refreshes the row along with the selection

However if the row selector is activated
[change of row color on selection]
the row refreshes with the check box value same as before

i dont wish to retain prev selections

need more inputs from your end
