SharePoint Form Validation is a client site validation tool which provides various validation options to users!

I want to share very useful in my opinion code snippets for WPF developers. Most of they were created my friend - Dmitrij Zakharov. Moreover I want to add a short description to each snippets. Note: The Code Snippet Inserter inserts a code snippet at the cursor location, or inserts a surround-with code snippet around the currently selected code.

If you want the full gory details, check out the .NET Services team blog post here. What follows below are some of the things that I think are most crucial to understand both for new developers and for developers unfortunate enough to be in a position of having to migrate a lot of code.

ASP.NET Web Deployment is, shall we say, problematic at times – at least for a hosted scenario where you can’t do dumps from a build server and you don’t have access to IIS (which means you can’t use WebDeploy). What you’re about to read isn’t specific to the Microsoft platform at all and works with any development tool. And NO, you don’t need a single thing installed on the server (save FTP) for it to work.

I've got a few ASP.NET MVC projects burning that will be leveraging Facebook Connect for user identity and profile data. I was impressed with how quickly I could get things running using the Facebook Developer Toolkit. Well-documented, good examples, and the API makes sense.

One of the frustrating aspects of working with CSS (one of many, actually) is the amount of duplication in a .css file. CSS does allow us to separate content from presentation, but, if I had a nickel for every time I did a search and replace for some hexadecimal RGB code replicated 5 times in a CSS file

So you want to write an application in .NET that’s location-aware? Let’s start with a code sample (console application) that will show you how to use a GeoLocationProvider to respond to location updates, and print those updates out to the console.

In this post, I’ll focus on a few lines of code from the latest version of that sample. Those few lines of code enable my custom script to benefit from the script loader’s features such as lazy and parallel loading and dependency management.

We all know when a page is requested, ASP.NET processes the page, its server controls, and finally sends the HTML to the client-side for the browser to render it. The time taken to download the HTML at the client side depends mainly on the final size of the page. If your page is data rich, it would take a lot of time to fetch it. So here I am presenting a technique to reduce the size of ASP.NET web pages.

This is a brief tutorial on Mindscape LightSpeed, an O/R Mapper which is super easy to setup and use. I am using on a project now and wanted to share how simple it is to use, compared to something like Entity Framework from Microsoft.

In my last blog post I have covered the new Silverlight 4 Webcam API and provided a demo that used my edge detection pixel shader to create a nice real time webcam effect. In this post I make an extended version available which can save webcam snapshots as JPEG files and I also discuss some limitations of the webcam API's built-in CaptureSource.AsyncCaptureImage snapshot method. Furthermore I will give some ideas on how to build a Silverlight 4 video chat / conference application on top of the provided JPEG capturing and encoding code.

Here are links to a few short video interviews by prebynski with C# MVPs and luminaries speaking while they attended PDC 2009 last week in Los Angeles. This is a chance to hear the interests and opinions of folks who are immersed in the culture and technology surrounding C#. All three of these interviewees are with authors who are currently working on new books about C#.

I casually mentioned two tricks for sharing the same XAML across Silverlight and WPF in the notes of a post a couple weeks ago. I used both techniques in my DataVisualizationDemos project (which compiles for Silverlight and WPF from the same source code) and wanted to call them out for others in similar situations. The feedback I got was quite positive - until someone tried the subclassing trick with HierarchicalDataTemplate. While there's no reason that shouldn't work, it doesn't.

When someone asked my former manager David Treadwell what he did on a daily basis his answer was “Go to meetings and delete email”. Unfortunately that often describes my life as well. It is always challenging to manage your time. I want to ensure I’m spending enough on technology, people, customers, etc.

Accessibility is important to consider when designing applications. Not only do those with visual, physical, speech, cognitive, and neurological disabilities benefit from software that is accessible, but those without these disabilities benefit as well. Silverlight makes it possible to create applications that address accessibility needs, and some colleagues of mine and I decided to explore some of the possibilities by creating a control and navigation template theme that maps to Windows system colors (this will allow the application to seamlessly respond to Windows high contrast mode color changes).

.NET Framework 4 Beta 2 has been out for a little while now. There are some subtle improvements to the ScriptManager control in ASP.NET 4.0 that few have picked up on yet. Allow me to introduce you to them! First, let me say that this is strictly about features in the server-side ASP.NET ScriptManager control, not the Ajax library in general. Also – if you do not use the ASP.NET Ajax library but you are a WebForms developer, I assume you, this article is still for you!

Last week I posted about the great new materials on Channel 9’s site and on Silverlight.net for Silverlight 4. I had several people ask me about a downloadable version of my “What’s new in Silverlight 4” whitepaper that is posted on Channel 9’s site in HTML format.

Yesterday I showed how we can map some of the Rx operators to an API which looks more like the F# base classes. Today I wanted to use these mapped operators in a WPF-application written in F#.

Have you ever wanted to give the user the ability to drag a file from you desktop or file explorer onto your Silverlight application? Well, up until now you couldn’t. What’s that sound? It’s a bird… it’s a plane… no, it’s Silverlight 4 Beta. Yes, Silverlight 4 Beta is coming to the rescue and giving you the ability to have your Silverlight application act as a drop target. And it is so easy to do. Observe.

Before Silverlight 4 if you wanted to dynamically add ellipses (the commonly used … to show that the sentence continues), you have to invent your own implementation which usually involves creating your own control that wraps a text based control and then manipulate the text inside based on the size. Similar to what Robby Ingebretsen had to do here.

I've gotten a few requests recently for the source code of the examples in Programming F#. I've attached them as a series of F# Script files. In the ZIP file you'll find a few gems

There are bugs, and then there are bugs. We recently hit one that fell directly in crazy-town category. What exactly would you do if you get this fun message: The query processor ran out of stack space during query optimization. Please simplify the query.

So, by now you should have heard that Silverlight 4 Beta was released at PDC 2009. One of the most interesting and fun features included in the release is the ability for you to access a users webcam and microphone. Even a fellow ElegantCoder wrote a short post on it. But I wanted to go into a little more detail. So I am going to show you have to access a list of webcams and microphones, capture video, and then take pictures and show them to the user. But, before I can show you how to use them, you have to have the Silverlight 4 Beta framework installed.
