Uncaught TypeError: Cannot read property 'css' of undefined

[aleem523Participant]

Hi,

I am using ‘jqxgrid’ with Angular in my application, when I navigate to one of the view where ‘jqxgrid’ is used.

I can see “Uncaught TypeError: Cannot read property ‘css’ of undefined “ on the console (Debug tool) and runs into infinite loop. causes serious performance issue to the application.

Here is the script below for your quick reference :

` $scope.getExperimentList = function () {
// Get sources data for experiments grid
var source = experimentService.getExperimentSource();
// create data adapter
var dataAdapter = experimentService.getExperimentDataAdapter(source);
// Get grid configuration for experiments
$scope.experiments = experimentService.getExperimentListConfig(dataAdapter, false, false, !isAdmin);

// Watch on experiment grid data.
$scope.$watch(function () {
return $scope.experimentData;
}, function (n, o) {
// n = the actual value
if (n != undefined) {
$scope.experimentData = n;
source.localdata = $scope.experimentData;
$(“#experimentGrid”).jqxGrid({ source: dataAdapter });
}
}, true)
};

html code :
<jqx-grid jqx-settings=”experiments” jqx-instance=”grid” id=”experimentGrid”></jqx-grid>

Hi aleem523,

You change the Grid’s source in a watch. If that watch is called multiple times or the data update causes that watch to be called, you will run in infinite loop.

Hey Peter,

Thank you for the quick response.

Is there a way to update the jqxGrid data(source) at runtime, after grid initialized?

I just removed grid’s source out of watch block, but still I can see the same error :

jqxgrid.js:7 Uncaught TypeError: Cannot read property ‘css’ of undefined

Hi aleem523,

Share a jsfiddle.net sample. We do not know what’s this error and what’s the code that caused such error to be raised on your side.
