title: EXTjs gridfilter: How to clearfilter without reloading store?
body: <p>In extjs GridFilters, is there a way to clear the filters without reloading the store?<br>
  This is the rquirement:<br>
  There is a grid(#1) and another grid(#2) below the grid. The grid(#1) has a list of ids, and when a particular id is clicked, the grid(#2) is popualted with a list of records that belong to that id.<br>
  And example might be:grid#1: list of all maangers<br>
  grid#2: list of all employees for a particular maanger.</p>
  
  <p>Grid #2 has a filter: on employee name.</p>
  
  <p>The rqmt is: When a selection is changed in grid#1, clear all the old filters, but do not relaod the store for grid #2 as grid#2 store will be loaded through another function.</p>
  
  <p>Please let me know how I can help by providing more info</p>
