I have 2 controllers i want to call a function in one controller in another. I'm using this and I'm not using any $scope. How can i call a function from one controller to another.
var app = angular.module("myapp", []);
app.controller("myctl", function () {
var parent= this;
parent.SayHello = function () {
// code
}
})
app.controller("otherctl", function () {
var child = this;
// how to call sayHello without $scope
})

You cannot, even if you are using $scope.
You cannot inject one controller to another controller.
In order to share the data among the controllers, consider using factory/service.
DEMO
var app = angular.module("clientApp", [])
app.controller("TestCtrl",
function($scope,names) {
$scope.names =[];
$scope.save= function(){
names.add($scope.name);
}
});
app.controller("TestCtrl2",
function($scope,names) {
$scope.getnames = function(){
$scope.names = names.get();
}
});
app.factory('names', function(){
var names = {};
names.list = [];
names.add = function(message){
names.list.push({message});
};
names.get = function(){
return names.list;
};
return names;

$parentif you have a child relationship. It all depends on context which you aren't providing much of.
