grid.getFilterPlugin().clearFilters(); grid.getFilterPlugin().getFilter('dataindex').setValue("value"); //string filter grid.getFilterPlugin().getFilter('dataindex').setValue(true); //bool filter grid.getFilterPlugin().getFilter('dataindex').setValue({gt:2, lt:9, eq:5}); //numeric filter grid.getFilterPlugin().getFilter('dataindex').setValue({before: new Date(2008,0,1), after:..., on:...}); //date filter grid.getFilterPlugin().getFilter('dataindex').setValue(['item1', item2]); //list filter grid.getFilterPlugin().getFilter('dataindex').setActive(false); //turn off filter
