This is what I am doing:
this.TabPanel.Grid.getStore().clearFilter (false);
alert(this.TabPanel.Grid.getStore().isFiltered());
and the alert shows: false. When I go on the page, I see that the filter is still selected(checked) and the results are also fitlered. What I am missing?
EDIT:Can I get a handle to the gridfilter object through my store? If yes, I can call the gridfilter.clearFilters().
How is that code running? Can you post a more complete example? If you have some component that is a user is using to set the filter(like some check box or something), you will still need to clear that manually as well.
