Question

I created a gridfilter like this:

var filters = new Ext.ux.grid.GridFilters({filters: [
{type: 'string',  dataIndex: 'ContactName'}
]});

I wish to override the buildquery method to provide custom logic.

When I do:

filters.buildQuery = function(filters){
alert(Ext.util.JSON.encode(this.store.baseParams.filterParams));

};

It works fine. But when I move the alert inside another function like this:

buildQuery1 : function(filters){
alert(Ext.util.JSON.encode(this.store.baseParams));
}

And call it like this:

filters.buildQuery = function(filters){
buildQuery1(filters);
};

The alert does not show. And I get this.store.baseParams is null or not an object.

I solved it like this:

filters.buildQuery = function(filters)
{ 
buildQuery1(this,filters);
 };

AND:

buildQuery1 : function(scope,filters){ alert(Ext.util.JSON.encode(scope.store.baseParams)); }

Not sure why this works 🙂
