Session timeout is the worst nightmare of a developer especially if you do not have much experience in coding but senior enough to design an small application which becomes a mammoth in few months. So to all the mid-level experience guy, here is the key to success, do not make session variables in code behind, instead, create separate c# file either in app_code or in a separate project which you can call Utils as it will act like your utility file and create a public property in it which will call your DB whenever your session is null like following. So let's create a never ending session for the c#, Here is the scenario, suppose you have a user data-table coming from database which is on another project/DB and you have to get it through AD authentication or let's imagine it's a heavy DB call so calling, again and again, will reduce the app performance and that's why we use session which is again a non-performing thing but still better than DB chat. Here is your...

Hello Everyone, I am an ordinary person with some highly looked after skills, not boasting about myself. But after coding in this IT industry for almost 5 years for the first time I am thinking:- Is delivering the code my only responsibility or is there anything else I need to look into as well? From last few month's I was highly involved in some entirely new domain which is financial, and when you play with the number you need to be highly focused, so unable to update my blog as well. When I was working on the urgent deadlines and tight estimates and being from a healthy UI background like css3, html5, responsive design, knockout js, less etc. I was put on the SQL server and asp.net with grid views and some freaked out Telerik controls. I know it's a learning for me and I can see why UX matters to every person in this entire world but not UI and you can write it on stamp paper. User Experience, with logical and functionally correct code, is the need of the hour to...

Well, I am writing this post after a really long gap of time, I was away from my blog due to some personal reason and aggressive deadlines for my project, so today I thought of writing a blog about my experience with sitefinity, (http://www.sitefinity.com/) which is Content Management System aka CMS from a very famous IT firm Telerik. The CMS is purely on HTML and has its own pros and cons, it doesn't have any custom widgets available and you have to design most of them. So while developing my client website for it I found issues about the CMS shortcoming and lack of documentation, basically lack of documentation is the major problem with this CMS. So we had a requirement, we need to show the AES encrypted adaptive bit rate video to the user, we were using azure services for this, but the major requirement is that we were using a CMS and we need to make everything dynamic i.e. Business User editable and a drag and drop widget, which includes: Video URL. Video Title. Vid...

Run CSS specific to Internet Explorer - Browser Hack Referencing to the following blog post, we are going to make CSS targeting exclusively to IE browser, to make it work first we should know what are media queries. A media query consists of a media type and at least one expression that limits the style sheets' scope by using media features, such as width, height, and color. Media queries, added in CSS3, let the presentation of content be tailored to a specific range of output devices without having to change the content itself. For Ex: < style > @media (max-width : 600px) { .facet_sidebar { display : none ; } } So below we will wrap the IE specific CSS rules in @media blocks and trick IE into rendering @media blocks that use media queries. Targeting only IE browsers Style rules defined in the following blocks will only be applied in IE, other browsers will ignore them. IE 6 and 7  @media screen\9 {     body { background: red; ...

Being a .Net Developer and using the open technologies, I have lots of options of taking the advantage of the framework but once you started growing in your career, more then What technology you use? the question become How the technology is used ? and that is Architecture. An architecture of a something you are implementing is very important once you start writing the code. If you are writing a mobile application that needs to be cross browser compatible and can work on on any mobile device, you need to follow the modern architecture that is getting common across all the application. The architecture should use SPA (Single Page Application) and REST api's and should be devoid of any stored proc to avoid complexity. Let's start with why to use SPA, A SPA is written in HTML5, JS, CSS3 and lots of other JS libraries. The other JS libraries has some basic needed libraries like .less or .sass for css maintenance, Require JS for correct Integration of code and ofcourse ...

Few days back I wrote for Solid and Grasp principles for oops http://www.developerscloud.org/2014/08/oops-beyond-four-pillars-solid-and-grasp.html . Now I am again extending it to make it more matured way to write code. Let start with coupling and cohesion. Loose/Low Coupling low dependency between classes; low impact in a class of changes in other classes high reuse potential High Cohesion measure of how strongly-related or focused the responsibilities of a single module are If methods of a class tend to be similar in many aspects, then the class have high cohesion In highly-cohesive system, code readability and the likelihood of reuse is increased, while complexity is kept manageable. Also check Encapsulate what varies Favor Composition over Inheritance Program to interface not implementation Strive for loosely coupled design between objects that interact For Interfaces Like an abstract base class: any non-abstract type inhe...

As we know  Object oriented programming is a type of programming paradigm based around programming  classes  and instances of classes called  objects . These can be objects that appear on the screen (e.g., pictures, textboxes, etc.) or are part of the programming (e.g. actors, connections, particles, etc as mentioned in my post  http://www.developerscloud.org/2013/02/what-is-oop-basic-concepts.html   written ages ago. Here we are going to extend the oops beyond its four pillars i.e. Abstraction Encapsulation Polymorphism  and Interfaces i.e.  Inheritance So first we will go through  SOLID and then GRASP SOLID Principles are principles of class design. • S RP: Single Responsibility Principle – An object should have only a single responsibility & all the responsibility should be entirely encapsulated by the class. – There should never be more than one reason for a class to change • O CP: Open/Closed Principle ...
