Kendo Grid doesn't display data if I use a function call for the data -

-

if use second read below commented out, grid displays data. if use first, can see data being returned in fiddler, grid doesn't display it. 

var $nisgriddatasource = new kendo.data.datasource({     transport: {         read: function () {             dataservice.newissuesstatistics();         }         //read: {             //url: "/api/poolapi/newissuessecurities"         //}     }  ...

this dataservice.newissuesstatistics method called sucessfully:

    newissuessecurities = function () {      return $.ajax({         url: "/api/poolapi/newissuessecurities"     });

can suggest why so?

you have tell kendo ui datasource it's received data. how function dataservice.newissuesstatistics() implemented? return promise? let's illustrative purposes does, how it:

var datasource = new kendo.data.datasource({   transport: {     read: function(options) {       dataservice.newissuesstatistics().done(function(stats) {         options.success(stats);       });     }   } });

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
