Angular timeout ($timeout) service promise

In angular JS, if you want perform some action after some time (or you want to wait for some time) you can use $timeout service. This service returns the promise which we can resolve by "then". In following example, it will take 2 seconds to call the function "toBeCalled".


function Controller($timeout) {

           wait(2).then(function () {

            })

            function wait(seconds) {
                return $timeout(toBeCalled, seconds * 1000);
            }

            function toBeCalled() {
                console.log("called after 2 seconds");
            }
        }

Entity Framework Code First Approach

ASP.NET Web API 2 Tips and Tricks

REST API offers only method per request type except the Get which comes two times (One for getting Single Record and one for all Records).

Note: You can not use both techniques in One Controller. you can use One only one technique in one controller.

How to Know when your angular rendering is complete (Callback function for ngrepeat/ng-repeat)

There are scenarios when you need to know that angular rendering is complete due to ng-repeat directive. Here we need to understand that the success call back method of $http does not mean your rows are rendered. following is the scenario where we can utilize this ng-repeat callback method,
1- You may need to perform particular Jquery Method after rendering of rows is complete.
2- Format generated rows after they are rendered.
3- I needed this to use data tables object ( $('#tbl').DataTable();) after rendering is complete.

To start with, we need to write an attribute level directive which we can call like,
