Redirection with ASP.Net friendly URLs

Posted by  |   |   |  3 comments   
In this post we are going to see how we can use Response.Redirect(Redirecttion) in asp.net friendly URLs. Before some day I have written a post about ASP.NET Friendly URLs – Cleaner, SEO friendly URLs. On that post one reader ‘Ramesh’ asked me that how we can do redirection with ASP.Net friendly URLs. So this post is in reply to Him.

How to redirect a page to ASP.Net friendly URLs:

Actually!! there is nothing to learn. It’s very easy You can directly use the ‘Response.Redirect’ with the ASP.Net friendly URLs. The NuGet Package itself takes care of all the things. You just need to write the route name as a parameter in ‘Response.Redirect’ and you are done!!

Uh!! don’t believe me!!. Let’s take a sample example. I am going to use by default template with ASP.NET Friendly URLs.  So for this example I have created a ASP.Net button in Default template AboutUs.aspx page. Once the click of that button we are going to use ‘Response.Redirect’ for redirection and redirect this page to Contact Page. Following is a html code for that button.

ASP.NET Friendly URLs – Cleaner, SEO friendly URLs

Posted by  |   |   |  6 comments   
Search Engine optimization is one of the key factor for your site. If you spend millions of dollars on making your website looks good and bug free then also its possible that you will not get attention of search engine because of your URLs.  For example you’re having shopping cart created in asp.net and you have not optimized your URL then it will look like following.

www.foo.com ?Product.aspx?Category=1& Page=1

 If you search engine read this URL then search engine will not know much about this URLs. Even normal people  who does not know querystring menaing(?Category=watch&Page=1) will not understand it. But If you have URL like following.

www.foo.com/prduct/category/watch/page/1

 It’s easy to read and search engine and normal people will know that you are loading products that belongs to category watch and this is a first page.

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; }
}
