I have found a very neat and simple way of binding an ItemControl to enum values. The trick is to use an ObjectDataProvider class which enables the creation of a XAML object available as a binding source. To show an example first of all I need an enum: public enum SampleEnum { Dog, Cat, Scrat, Hefalump } To make it available for binding I will define it as a resource with an x:Key. <Window x:Class

VS 2010 comes with ready made snippets which helps you save time while coding. You insert a snippet by typing the name of the code snippet and hitting the Tab key twice. You can also use the following method if you wish to see a listing of snippets available. Press Ctrl + K, Ctrl + X Select ASP.NET MVC2 with the arrow keys and hit enter to see a list of snippets available. The MVC related snippets

One of the top reported Microsoft Connect issues with VS 2010 has been an issue where context menus scroll even when there is sufficient screen real estate to show the menu in its entirely (with no scrolling required). The VS and WPF teams issued public hotfixes today that you can download to fix this issue. You can learn more and download them here. You can review my previous posts about other pu

jQuery Templates, Data Link, and Globalization Accepted as Official jQuery Plugins The jQuery library has a passionate community of developers, and it is now the most widely used JavaScript library on the web today.

A few hours ago we released a Microsoft Security Advisory about a security vulnerability in ASP.NET. This vulnerability exists in all versions of ASP.NET. This vulnerability was publically disclosed late Friday at a security conference. We recommend that all customers immediately apply a workaround (described below) to prevent attackers from using this vulnerability against your ASP.NET applicat

This is the twenty-eighth in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. This blog post continues a series of posts I’m doing that cover the new improvements we made around web deployment. In my first post in the deployment series I provided an overview of the new VS 2010 Web Deployment features. In today’s post I’m going to be discussing Microsoft Web Deploy – which is a

This morning we posted the "Preview 1" release of ASP.NET MVC 3. You can download it here. We’ve used an iterative development approach from the very beginning of the ASP.NET MVC project, and deliver regular preview drops throughout the development cycle. Our goal with early preview releases like the one today is to get feedback – both on what you like/dislike, and what you find missing/incomple

Entity Framework 4 "Code-First": Custom Database Schema Mapping Last week I blogged about the new Entity Framework 4 "code first" development option. The EF "code-first" option enables a pretty sweet code-centric development workflow for working with data. It enables you to: Develop without ever having to open a designer or define an XML mapping file Define model objects by simply writing "plain

Last week I published several blog posts that covered some new web development technologies we are releasing: IIS Developer Express: A lightweight web-server that is simple to setup, free, works with all versions of Windows, and is compatible with the full IIS 7.5. SQL Server Compact Edition: A lightweight file-based database that is simple to setup, free, can be embedded within your ASP.NET appli

One of the things my team has been working on has been a new view engine option for ASP.NET. ASP.NET MVC has always supported the concept of "view engines" – which are the pluggable modules that implement different template syntax options. The "default" view engine for ASP.NET MVC today uses the same .aspx/.ascx/.master file templates as ASP.NET Web Forms. Other popular ASP.NET MVC view engines

Developers today build and test ASP.NET sites and applications using one of two web-servers: The ASP.NET Development Server that comes built-into Visual Studio The IIS Web Server that comes built-into Windows Both of the above options have their pros and cons, and many ASP.NET developers have told us: "I wish I could have the ease of use of the ASP.NET Development Server, but still have all the po

Notice that a single language, such as English, can have several language tags. Speakers of English in Canada format numbers, currencies, and dates using different conventions than speakers of English in Australia or the United States. You can find the language tag for a particular culture by using the Language Subtag Lookup tool located here: http://rishida.net/utils/subtags/ The jQuery Globali

jQuery Templates and Data Linking (and Microsoft contributing to jQuery) The jQuery library has a passionate community of developers, and it is now the most widely used JavaScript library on the web today.

As developers we often spend a large part of our day staring at code within Visual Studio. If you are like me, after awhile the default VS text color scheme starts to get a little boring. The good news is that Visual Studio allows you to completely customize the editor background and text colors to whatever you want – allowing you to tweak them to create the experience that is "just right" for yo

This is the twentieth in a series of blog posts I’m doing on the upcoming VS 2010 and .NET 4 release. Today’s blog post covers some of the nice improvements coming with JavaScript intellisense with VS 2010 and the free Visual Web Developer 2010 Express. You’ll find with VS 2010 that JavaScript Intellisense loads much faster for large script files and with large libraries, and that it now provides

.net 4 introduces the CustomValidationAttribute, a member of System.ComponentModel.DataAnnotations that supports validation of your business logic. Until now, validation rules were limited based on the available attributes (required, stringlength, regex, and range) plus those you created by subclassing System.ComponentModel.DataAnnotations.ValidationAttribute. CustomValidationAttribute lets you de

This past week I’ve been traveling around Europe giving a bunch of presentations (approximately 5 hours in each country) – Norway on Tuesday, Sweden on Wednesday, Denmark on Thursday, and Belgium on Friday.

Earlier today the ASP.NET team launched a new Microsoft Ajax CDN (Content Delivery Network) service that provides caching support for AJAX libraries (including jQuery and ASP.NET AJAX). The service is available for free, does not require any registration, and can be used for both commercial and non-commercial purposes. What does a CDN provide? Content delivery networks (CDNs) are composed of "edg

For some reason, the generic Dictionary in .net 2.0 is not XML serializable. The following code snippet is a xml serializable generic dictionary. The dictionary is serialzable by implementing the IXmlSerializable interface. using System; using System.Collections.Generic; using System.Text; using System.Xml.Serialization; [XmlRoot("dictionary")] public class SerializableDictionary<TKey, TValue> :
