Title: remote filter listener is not working
Post by: gtwangi on December 17, 2018, 07:17:33 pm

I am using pqgrid v5.5 and chrome.
I expect that when filter option is selected, the listener function is called.
but 'change' listener is not firering.
what am I missing?

{
    dataIndx: "TmpltNm",
    title: "Template",
    filter: {
       crules:[{condition:'equal'}],
       options : app.sheet.getFilterOptions("TMPLT_NM")
       listener : {
         change : function(ui, evt){
         ...
        }
    }
}

}

Yes listener is supposed to fire as per docs but it's not.

Anyway it's not required for remote filtering for > v5.2 as grid calls the filter method internally.

I use both infinite scrolling and remote filter on the same page.
so I think that I need to clear grid data after filter is selected. otherwise unfiltered data remain in grid.
this works well on free version.(v2.4.1)
How could I use listener for remote filter as free version? or Is there alternative ways?

That's a good point but beforeFilter event takes care of resetting the data cache

Code: [Select]

beforeFilter: function(){
    pqIS.init();
},

in this example of infinite scrolling: https://paramquery.com/pro/demos/infinite_scroll

So filter.listener is dispensable.
