Ext.NET 2 Now Available

ext.net2After over more than year and a half of development, the official Ext.NET 2 release is now available for download.

Ext.NET 2 integrates the Sencha ExtJS 4 library making it even easier for ASP.NET developers, both Web Forms and MVC (more on that below), to build the next generation of HTML5 enabled web applications.

With access to 100+ Controls, Ext.NET developers now have the largest integrated suite of ASP.NET Controls and HTML5 based Charts available today.

Thousands of new features and improvements have been added to Ext.NET 2, and it’s going to take more than a few blog posts to work through the details. To help you get the most out of Ext.NET, we’re starting a regular blog series to communicate new features, functionality, and developer tips.

Quick Installation

The quickest and easiest way to install Ext.NET 2 is using the Visual Studio Package Manager and NuGet. One simple call to Install-Package Ext.NET using NuGet and everything you need will be automatically installed and configured within seconds.

PM> Install-Package Ext.NET

All download options are available on the new Ext.NET download page.

Public release versions of Ext.NET Pro, including the Examples Explorer, and the new MVC Examples Explorer are available with full source code from GitHub. Be sure to keep up to date by following the Ext.NET Pro project.


With Ext.NET 2 we are thrilled to announce full support for ASP.NET MVC, including full support for the Razor View Engine.

Everything in Ext.NET now “just works” in both Web Forms and MVC projects. All Ext.NET Components, all properties, all methods and all client/server-side events are fully supported.

Please note, this is not some subset of additional widgets, or an under-developed side library. With Ext.NET you choose your platform and know you need not make sacrifices for missing functionality. The versatility of language options allow Ext.NET developers to choose an architecture best suited for their project and team.

The following sample demonstrates creating the same basic Window Component using three different language options: ASP.NET MVC Razor, ASP.NET Web Forms markup, and C# code-behind.

Example (ASP.NET MVC Razor)

    .Title("Hello World")
    .Html("An Ext.NET Window")

Example (ASP.NET Web Forms)

    Title="Hello World"
    Html="An Ext.NET Window"

Example (C#)

var win = new Window {
    Title = "Hello World",
    Icon = Icon.Application,
    Height = 215,
    Width = 350,
    BodyPadding = 5,
    Html = "An Ext.NET Window"



New in Ext.NET 2 (ExtJS 4) is a plugin free (no Flash!) Charting package. Charting is included in the main Ext.NET library and not a separate package. Install Ext.NET and you also instantly have a fully integrated powerful Charting package right within the library.

And… just like all other Components in Ext.NET, the Charting library is fully supported in ASP.NET MVC Razor View Engine.


        .Label(new SeriesLabel
            Field = new string[] { "Name" },
            Display = SeriesLabelDisplay.Rotate
