extjs4.2 - Extjs Grid Panel Filter - Clear filters only in one column -

this question (extjs gridfilter: how clearfilter without reloading store?) shows how clear filters on entire grid.

is there way clear filters in specific column? example, if have column list filter has 20 options , select 8 of them, i'd button uncheck of those, leave other filters i've selected remain in tact.

the 'size' column on demo example of filtering looks like: http://dev.sencha.com/deploy/ext-4.0.0/examples/grid-filtering/grid-filter-local.html

you can setactive method of filter.

and here's how can reference filter:

// filtersfeature adds filters property grid bound grid.filters.getfilter('size').setactive(false) 

edit: how uncheck boxes

var filter = grid.filters.getfilter('size'); filter.menu.items.each(function(checkbox) {     // second argument suppress check event in order prevent     // unexpected behaviour, filter reenabling , trying     // update store several times in row     checkbox.setchecked(false, true); });
