The Binding class has a few properties that can be set to a text, including spaces. The properties StringFormat, TargetNullValue and FallbackValue are such properties. These properties exist in WPF and newly also in Silverlight 4.

This morning, very early (or very late depending how you see it), I learned that one of the sessions I submitted to the MIX 2010 open call for speakers had been picked by the public. Out of 169 sessions, only 12 were picked, so you imagine my feelings right now. Honestly, I am sure that this will be a good session, but it could have gone either way, and I had prepared myself mentally for the alternative possibility too. Read the rest of this entry » ...

In this post, we will get ourselves familiar with one of the popular Twitter API – Twitterizer & the famous Facebook SDK which was recently released by Microsoft. We will be using them in quite few of our up coming project will be doing in the near future. Go to these pages and make sure you download the packages and have the DLLs ready. “Twitter”izer This is very famous .Net library to enable easy communication with Twitter.

In my previous post, I went through creating the KeyedCollectionEx class which allows easier consumption of the KeyedCollection class (no need to derive anymore, just provide a delegate). One of the problem I encountered was that when using it as an ItemsSource in WPF, any changes to the collection will not be shown in the UI. This is because the class doesn’t implement INotifyCollectionChanged interface. So, let’s add that. The implementation is fairly straightforward; the class itself has all of ...
At one of the clients I am working with we had a strange issue this week. A new employee joined the development team as a QA lead and was given a laptop to use that is a couple of years old. The firm has been in the process of upgrading their equipment to Windows 7 and thus far hasn’t really had any issues. Well, on this particular computer, our WPF application would install (it’s click once) and open but then hang. Very odd indeed. In looking at our application log, I found many instances of this ...

A little over 2 years ago, I saw my peer’s code that uses the KeyedCollection<TKey, TItem> class. I never seen it before, and it is actually a pretty nice class. It is essentially a dictionary class, but with the stipulation that the key for each item added to the dictionary can be retrieved from the item itself. With a Dictionary, every time we wanted to add a new item into it, we have to call its Add method, which accepts 2 parameters, the key for the item and the item itself. In most cases, ...

Well, another year, and heck …. even another decade and 2010 is going to be such an important year, or kick-off year for technology that I thought I would take a stab at making some technology predictions on what I think might happen this year. Technology always has these “next thing” items coming forward that it is really hard to even really know what is for real. Technologies might be quite good – but it will also take additional things like community ground swell or true behind-the-scenes business ...
This year Microsoft decided to have an open call for sessions for the MIX 2010 in Las Vegas. This conference, in case you don’t know it yet, is a great 3 days about modern client technologies, such as ASP.NET, Windows Presentation Foundation and of course Silverlight. This year, MIX is taking place from the 15th to the 17th of March 2010 in the Mandalay Bay hotel in Vegas. Today, the voting began! I didn’t count them, but there seems to be more than 100 sessions lined up, and the competition is fierce: ...
I have had a couple of discussions with some former co-workers in the past couple of weeks regarding "what I am doing now", and each one of them seems to have the same "whoa, thats different" comment on it. To be honest, I felt the same way. It really seems like over the past 7-8 years, Microsoft has gone against the grain of what they had been doing back in the traditional ASP days, in continuing to produce new technologies (.Net Framework / ASP.Net / Atlats / AJAX / XAML / WPF / WCF / Silverlight ...
I am working on my first significant WPF application and found myself in need of a simple visual color picker. I quick trip to Bing linked me to a Sacha Barber CodeProject project that met most of my requirements. His associated blog post is here. My biggest unfilled need was the ability to set the initial color, so I set about adding that to the original code. I made a few changes along the way. The revised code can be downloaded here. I made the following changes to the ColorPicker control: Set ...
For me one of the coolest new features added in Silverlight 4 is support for capturing video and audio using webcams and microphone. As we’ve seen during Scott Guthrie’s keynote demonstration it is now possible to capture image frames from video stream and apply some interesting effects to it. On top of that we can even process the video and audio streams directly on the client (i.e. inside the browser). Because Silverlight 4 Beta was already available at PDC I could try the webcam support right ...
Wow, it only seems like just last week I was sitting at my PC trying to determine what I was going to concentrate on in software development for 2009. I had also just started the Frederick .NET User Group (FredNUG) in September 2008 and I was trying to figure out how to get speakers scheduled. Then, things started to quickly fall into place. My local INETA mentor, Frank La Vigne, provided me with a few names of well respected .NET MVPs who would most likely be interested in speaking at FredNUG. (Thanks ...

This year has been a pretty amazing year. A few weeks ago, I was writing about my first year at IdentityMine. A little more than one year ago I was closing the Siemens book (after around 13 years of working into Building Automation, but always from a software engineer perspective) and started the IdentityMine chapter of my life :). As I mention in the post in question, this first year was a very interesting and also challenging year. Interesting because I got to work with some of the best creative ...

One of the MVVM Light Toolkit’s user requested that I add the possibility to pass the EventArgs of an event to the ICommand that it is bound to through the EventToCommand trigger. At first I was a bit reluctant because it seems like a transgression of the rule that says you should avoid to have too much knowledge about the UI layer in the ViewModel. For example, if you have a RelayCommand in the ViewModel that expects a MouseEventArgs, it kinds of binds you to a certain kind of UI element, which ...

I have been a developer for over 10 years, and at one point or another completely relied on the knowledge of someone with more experience than I had to make something work. I figure that it's time for me to start giving back.

I have a solid background that covers ASP.Net (C#/VB.Net), Traditional ASP, Javascript, custom AJAX ...

Technorati Tags: WPF WPF patterns : MVC, MVP or MVVM or…? What to use? Model-view-controler, the model-view-presenter or the new paradigm called model-view-viewmodel? MVC is kind of template and also a framework that can be used in VS 2005 and VS 2008. MVVM is a part of WPF which can be used to create windows apps. It's common practice to let the UI layer do more than it should. Without a clear separation of responsibilities, the UI layer can often become a catch-all for logic that really belongs ...
Technorati Tags: Silverlight Why Silverlight is the future This article was written by Rockford Lhotka several month ago. But, all the concepts are still relevant to day. This is just a great article. Silverlight, and the reason it almost instantly gains traction in any conversation with clients, is that it is independent of Windows. They like the idea that it works across Windows versions without worrying that Microsoft will fix some Windows thing and break their app. Silverlight gives the option ...

If I can choose the one most important feature in Silverlight 4 beta that can kill WPF apps I will choose the net.tcp support. One of the major performance improvements in Silverlight was the possibility to add binary ...

Thanks to all the attendees who came to my session on Developing WPF Applications with Prism at Central Penn .NET Code Camp.

Well... Hello.

Well, here I go again. This is my third try at being a blogger. Some would say that tenacity is a good thing. My wife might disagree. I've been solving business problems using the Microsoft stack for almost eight years. I've written a lot of code that I'm not proud of and I've learned a few things along the way. My intention is to share a few morsels with the development community from which I've taken so much over the years. Most of this blog's posts will probably be "SharePointy". That's not to ...
