The two-way data binding in AngularJS is very powerful, especially when there is a direct mapping of input data to view-model-data. But, when the data mapping requires some translation, interpretation, or validation, you need to get your hands a little dirty - you need to get more involved in how data changes are propagated within your Controller(s). As this has happened to me, I've been forced to think more deeply about my AngularJS application architecture; and, as a result, I've found that my life is often simplified (in the long term) by calling a directive to watch before I bind the data to View model. Factory To Monitor Changes This is easiest and effective way because of these reasons : 1) I just need to call a Trigger Method with scope which should be monitored 2) Once the data is retrieved from Ajax call , I just Initialize the data 3) If there are any changes to bound data on the form and user tries to navigate to another page, I get Confirm box on the

Thoughts on C# 7.0 Local Functions. Potential Features - Local Functions Frankly, when I first tried this, I thought that it's just a nice and compact way of defining local helpers. In fact, it's much more interesting and useful feature. Today I'm going to explore and explain it in more details. Let's  start with a brief overview of the current situation. Before Local Functions Private methods The first option that existed in C# 1 is having a private method. That’s a clean and simple solution. It has few issues, though. PrintMe might have no sense outside of ThatTime method, but it’s accessible for every other method inside the class. It will be taken into account by IntelliSense. Func and Action We can try to hide our helper inside the scope of ThatTime method by converting it to Func<int, string>: Any disadvantages ?? Yep, a lot. The call is unnecessary expensive: it will produce  more all

There is always a havoc on handling dates in the application either it's java /dot net or angular . So here is the best way I found in order to overcome the problem . Date Directive Here I am going to explain about angular date filtering concept and how to  use filtering concept to filter Date across your application.It is always better to create a date.js file for those filtering concept.  The advantage of this is you can very easily filter the data anywhere in your view by just placing directive. This can be achieved by using following code in your module defined, for example : CYW.date below. angular.module('CYW.date', []) .filter('stringToDate', function () { return function (input) { /// gets Date input, if not, returns null. Also sets the date to /// correct format if (!input) return null; var date = moment(input); return date.isValid() ? date.format('MM/DD/YYYY') : null; }; }

In this article, let's discuss on Tuple Class in C# and the potential new proposals that are being considered for C#7. Potential Features - Tuple What is Tuple in C#? Basically, a  tuple  ( Tuple in C# ) is an ordered sequence, immutable, fixed-size and of heterogeneous objects, i.e., each object being of a specific type. The  tuples  are not new in programming. They are already used in F#, Python, and databases. A tuple allows you to combine multiple values of possibly different types into a single object without having to create a custom class. This can be useful if you want to write a method that for example returns three related values but you don’t want to create a new class. System.Tuples namespace supports Tuple class in C#. The purpose of a tuple is to create a way to return multiple values from a function. class CodeYourWayTupleDemo { static void Main() { // Create three-item tuple. Tuple tuple = new Tuple (10, "Code

This demo shows how to read a CSV file and get its content into scope by using angular . Let's consider the view where we will be having Upload control and that's very simple code . Below would be the HTML file. If you notice the  accept   attribute on file upload control above forces the browser to accept files type  .CSV  but again user can change it anytime and select another file . Have a validation for file type if you want to restrict to CSV only  Now Let's define the Controller File which reads the input type .  For Demo Purpose I am just copying all contents into scope .Choose your implementations according to Your need !!  Result of Code  : CodeYourWay Page
