How can I find length of kendo dataSource? - angularjs

Question

I am trying to find length of kendo grid dataSource, but I am always getting 0 in return. How can I get the total length of dataSource? I have added Control service that is dataSource for the grid.
ctrl.js
$scope.alignedProcessesToControlGridOptions.dataSource = ControlRatingGridDataService.getAlignedProcessesToControlGrid($stateParams.controlId);
var data = $scope.alignedProcessesToControlGridOptions.dataSource.data().length;
console.log('GRID DATA', data);
DataService.js
getAlignedProcessesToControlGrid: function(controlKey) {
var countNew = 0;
return new kendo.data.DataSource({
type: 'json',
serverPaging: true,
serverSorting: true,
serverFiltering: true,
transport: {
read: function(options) {
var gridSearchObject = {
skip: options.data.skip,
take: options.data.take,
pageSize: options.data.pageSize,
page: options.data.page,
sorting: options.data.sort,
filter: options.data.filter
};
return $http.post(
'app/control/rest/allAlignedProcessesToControl/' + controlKey, gridSearchObject).success(
function(data) {
countNew = data.totalCount;
options.success(data.resultDTOList);
});
}
},
pageSize: 5,
schema: {
model: {
id: 'riskInProcessKey',
fields: {
processName: {
editable: false
},
epcfName: {
editable: false
},
erhName: {
editable: false
},
ctlGeolocationsText: {
editable: false
},
ctlPerformanceRatingText: {
editable: false
},
ctlEffectivenessRatingText: {
editable: false
}
}
},
total: function() {
return countNew;
}
}
});
},

Assuming your HTML for the grid looks something like...
$("#grid").kendoGrid({
dataSource: {
// your datasource
},
dataBound: onDataBound
});
Create a function for the dataBound event...
function onDataBound(e) {
console.log(e.sender.dataSource.view().length);
}
