I want menus to be loaded at the start of the application and I have multiple pages in MVC, so the problem is getting the error stated that controller not registered. so can you tell me how can I handle ng-app and ng-controller in master page and pages?

I am loading menus as follows:

 app.controller('masterctrl', function ($scope, $http, $window) {
   $scope.getmenus = function () {
    var holding_url = encodeURI(APIURL + "getmenus");
    $http.get(holding_url)
        .then(function (response) {
            $scope.names = response.data.t1;
            $scope.menu = [];
            $scope.childrenmenu = [];
            $scope.count = 0;
            angular.forEach(response.data.t1, function (value, key) {
                if (value.parentid == 0) {
                    $scope.menu.push(value);
                }
            });

            angular.forEach(response.data.t1, function (value, key) {
                if (value.parentid != 0) {
                    angular.forEach($scope.menu, function (value2, key2) {
                        if (value.parentid == value2.menuid) {
                            if (value2.children == undefined) {
                                value2.children = [];
                                value2.showChildren = false;
                            }
                            value2.children.push(value);
                            $scope.childrenmenu.push(value);
                        }
                    });
                }
            });        

            angular.forEach(response.data.t1, function (value, key) {
                if (value.parentid != 0) {
                    angular.forEach($scope.childrenmenu, function (value3, key3) {
                        if (value.parentid == value3.menuid) {
                            if (value3.childrencc == undefined) {
                                value3.childrencc = [];
                                value3.showChildren = false;
                            }
                            value3.childrencc.push(value);
                        }
                    });
                }
            });

Please see image due to that error data in table is also not loading properly, because master page and pages controller can not work together.

you need to bootstrap them using angular.bootstrap()

first give id to the child div lets say App2

<div class="ibox float-e-margins" ng-app="childview" id="App2">
</div>
 angular.bootstrap(document.getElementById("App2"), ['childview']);

this will allow Angular to run subsequent views to run on the dom
