问题
I have a local Grid with a set of columns & filters. When I specify filter criteria (via header dropdown menu), the rows displayed is a subset of the entire store.
When I remove a filter, the header dropdown menu is updated correctly to omit the criteria dialog. But the rows displayed are not un-filtered.
How do I trigger a recalculation when the filter is removed?
It is as simple as this:
public class ReloadableGridFilters<T> extends GridFilters<T> {
/**
* extended to call the reload()
* @see com.sencha.gxt.widget.core.client.grid.filters.AbstractGridFilters#removeFilter(com.sencha.gxt.widget.core.client.grid.filters.Filter)
*/
@Override
public void removeFilter(Filter<T, ?> filter) {
super.removeFilter(filter);
reload();
}
回答1:
After removing filters, for loading previous data we must override protected void reload() {} method of GridFilters
