from above code able values treepanel grid panel double clicking.

i want column group values if double click same leaf in treepanel.

for example if double click bart 6 times

name  email              phonenumber     groupby(number of times) bart  bart@simpsons.com   555-222-1234    6 

it should not append same value in grid panel. 1 please me.

you'll need add count field store's fields. then, you'll need add field grid. when double-click tree, you'll need check store see if record exists. if does, change value in count field; otherwise, add new row.

        itemdblclick: function (tree, record, index) {             var s = ext.getstore('simpsonsstore'),                 existingrecidx = s.findby(function (r) {                     return r.get('email') === record.raw['email'];                 });              if (existingrecidx === -1) { //row not found                 record.raw.clickct = 1;                 s.loadrawdata([record.raw], true);             } else {                 var r = s.getat(existingrecidx);                 r.data.clickct++;                 grid.getview().refresh(); //once data has changed                                           //refresh grid             }         }
