Question

ColdFusion 8

I have a cfgrid that that is based on a query. It is not bound to a cfc function because I want a scrolling grid, not a paged grid (you must supply the page number and page size if you use BIND).. I can figure out how to make it filter on one column by using the following code, but I really need to filter on three columns…

grid.getDataSource().filter("OT_MILESTONE",t1);

Adding more to the filter string does not do the trick…it ignores anything more than the first pair of values..

so..I thought if I called a function that passes the three values and returned the query results to me, I could replace the Data Store for the grid..but I cannot figure out the syntax to get it to replace.

The returned variable for the query has the following format:

{"COLUMNS":["SEQ_KEY","ID","OT_MILESTONE"],"DATA":[[63677,"x","y"]]} 

Any ideas?

after much blood, sweat, tears and swearing..here’s the answer, in case anyone else might need to filter a cfgrid by more than one variable:

            var w1 = ColdFusion.getElementValue('wbs');
            var t1 = ColdFusion.getElementValue('task');    
            var p1 = ColdFusion.getElementValue('project');

            grid = ColdFusion.Grid.getGridObject('data');
            store = grid.getDataSource();
            store.clearFilter();
            store.filterBy(function myfilter(record) {
                    var wantit = true;
                        if (trim(w1) != '') {
                            if(record.get('WBS_ID') != w1) {
                                wantit = false;
                        }}
                        if (trim(t1) != '') {
                            if(record.get('OT_MILESTONE') != t1) {
                                wantit = false;
                        }}
                        if (trim(p1) != '') {
                            if(record.get('PROJECT') != p1) {
                                wantit = false;
                        }}

                    return wantit;
                });

            ColdFusion.Grid.refresh('data',false); 

you will need a JS trim function…

Make sure the column names are caps…
