ExtJS - Custom Column Renderer on TreeGrid isn't being fired -

-

i have extjs treegrid , i'm trying add custom renderer particular column. unfortunately it's not working - event isn't being fired , no warnings given off. couldn't find api treegrid either. has else experienced this?

here's code:

    var tree = new ext.ux.tree.treegrid({         title: 'my tree grid',         loader: treeloader,         columns:[{             header: 'title',             dataindex: 'title',             width: 500         },{             header: 'testing',             width: 100,             dataindex: 'testing',             renderer: function(value) {               console.log('test');             },             align: 'center'         }]      });

thanks!

there no api treegrid because it's user extension (ext.ux). you'll have take @ source code more information. if don't have source in project, go following page:

http://dev.sencha.com/deploy/dev/examples/treegrid/treegrid.html

and hit "view source" ctrl + u. there can link treegrid.js , other supporting js files.

i noticed treegrid extends treepanel, in turn extends plain old panel. there doesn't appear reference gridpanel, don't believe there column renderer you'd expect if using component. gather, example (tree-grid.js) instead uses xtemplate rendering column data:

    var tree = new ext.ux.tree.treegrid({         title: 'core team projects',         width: 500,         height: 300,         renderto: ext.getbody(),         enabledd: true,          columns:[{             header: 'task',             dataindex: 'task',             width: 230         },{             header: 'duration',             width: 100,             dataindex: 'duration',             align: 'center',             sorttype: 'asfloat',             // ================================== //             // acts column renderer             tpl: new ext.xtemplate('{duration:this.formathours}', {                 formathours: function(v) {                     if(v < 1) {                         return math.round(v * 60) + ' mins';                     } else if (math.floor(v) !== v) {                         var min = v - math.floor(v);                         return math.floor(v) + 'h ' + math.round(min * 60)                              + 'm';                     } else {                         return v + ' hour' + (v === 1 ? '' : 's');                     }                 }             })             // ================================== //         },{             header: 'assigned to',             width: 150,             dataindex: 'user'         }],          dataurl: 'treegrid-data.json'     });

try using xtemplate purposes. if doesn't meet needs you'll have provide more information.
