When "Clear Filter" in grid column filtermenu is clicked,grid's dataSource's filter method is called even though the grid is actually not filtered with that field yet. eg. Load this page http://demos.telerik.com/kendo-ui/grid/remote-data-binding and directly click clear filter of any column field. It'll query the remote data. I don't want this behavior. Because the grid is not filtered by that field yet.
Can you report this case via our forums or support system on telerik.com? Thus our support team will investigate and advise you accordingly. Thank you for your understanding.
I asked to add this behavior via support system and he responded me to write it here.
