Question

In this example:http://www.sencha.com/forum/showthread.php?14503-Grid-Filter-(Plugin), at the bottom of the page, the ‘buildQuery’ method of the gridfilter is overridden to provide custom logic. the scope of the methos is GridFilter. If in this scope, I want to access the datastore of the grid, can I do it?

The objective is to add the filter parameters to the ‘baseParams’ of the datastore.

Answer 1

The store is a property of the Ext.ux.grid.GridFilters object. As such, you should be able to access it normally using this.store

From the example at the bottom of the page you’ve linked to it should be as easy as the following:

plugins: new Ext.ux.grid.GridFilters({
    buildQuery: function(filters){
        this.store.
        var p = {};
        for(var i=0, len=filters.length; i<len; i++){
            // Custom filter serialization

            //not sure what format filters comes in
            this.store.setBaseParam('your_param', filters[i])
        }

        return p;
    }
});
