Getting started with Twitter Bootstrap and ASP.Net MVC

Posted by  |   |  , ,  |  6 comments   

Update: Now with ASP.NET MVC5 you don't need to install twitter bootstrap nuget package now its by default available with default template.

In this blog I am going explain how we are  going integrate Twitter Bootstrap library with ASP.Net MVC.

What is Twitter bootstrap:

Twitter Bootstrap is open source library created by Twitter. As per twitter it’s Sleek, intuitive, and powerful front-end framework for faster and easier web development. It’s full featured framework for creating web sites. It includes CSS framework, JavaScript, JavaScript plug-ins,typography, Html scaffolding. There are lots of themes also available that are available so you can use that right away.

Integrating Twitter bootstrap with ASP.Net MVC:

Earlier we have to manually integrate Twitter bootstrap into the ASP.NET MVC like here. But now We have Twitter.Bootstrap.MVC4 Nuget packages that saves lots of time to adding bootstrap to MVC4 template. It’s very easily combines bootstrap into ASP.NET MVC application thanks  to it’s authors Matt Hinze and Eric Hexter.

As per Eric Hexter It’s provide following features.
  • JS and CSS bundling/minification of Twitter Bootstrap files the MVC4 way
  • Incorporate a jQuery validation fix to work with the bootstrap javascript
  • Razor Layout templates using Twitter Bootstrap markup.
  • Menus using Navigation Routes, including submenus and hiding menus by context(logged in vs anonymous)
  • Runtime Scaffolding – default Index, Edit and Detail views.. You provide thePOCOs and we will render the CRUDviews.
  • Post Redirect Getsupport using the Bootstrap Alert styles.
  • A Sample to show how to use all of this stuff

SelectMany operator in Linq C#

Posted by  |   |  ,  |  No comments   
SelectMany is an important operator in Linq. It takes each element of a sequence to an IEnumerable and flattens the resulting sequences into one sequence. You can find out more information about different overload list from the below link.

http://msdn.microsoft.com/en-us/library/system.linq.enumerable.selectmany.aspx

In this post I am going to explain How it can be really useful when you want to find list related to two entities. Practical example will be like a person can have multiple address and if you want to find list of addresses that are used with person then this SelectMany operator can be really useful.

So for this example First, I have create Address class with Street and Postalvcode property
public class Address
{
    public string Street { get; set; }
    public string PostalCode { get; set; }
}

How to create overloaded web methods in asp.net web service?

Posted by  |   |   |  No comments   
Recently some of colleagues were discussing about how to create overload methods in web service. We can’t directly create overloaded method web methods for web service. So I thought It would be great idea to write a blog post about it.

Function Overloading:


Function overloading is one of most known concepts of Object Oriented Programming. It’s a technique to implement polymorphism in code. Like in other programming language in c# you can also create multiple functions with same name and different argument. In function overloading function call will be resolved by ‘Best Match Technique’.

Problem: You cannot directly overload method in web service:


To understand this let’s create a simple web service with two HelloWorld Methods one with parameter and one without parameter both will return a string. Following is a code for that.

Visual studio 2012 color editor- Make Visual studio 2012 Colorful

Posted by  |   |   |  2 comments   
This blog will be part of visual studio 2012 features series.

I personally like the Metro UI for Visual Studio 2102 but  still some people are not happy with it. They really like Old Visual Studio 2010 layout and they wanted to have same kind of color in visual studio 2012. For those who want to change the color of Visual studio there is a plug in called Visual Studio 2012 Color Theme editor. From which you can set colors for visual studio UI and make your visual studio look colorful. Following is a link for that.

Once you download that from above location and click on installer it will ask for accepting terms and conditions like following.
