Technorati Tags: .NET,INotifyPropertyChanged... In my last post, I talked about using a Visual Studio code snippet for properties in classes implementing INotifyPropertyChanged: The code snippet lets me create the properties faster, but it's still a lot of repetitive "setter" code for each. What if I moved the "has the value changed?" and backing field update logic out of the property setters and replace my NotifyPropertyChanged method with this CheckForPropertyChange method?: protected bool CheckForPropertyChange<T... ...
Technorati Tags: .NET,INotifyPropertyChanged... Kevin Grossnicklaus gave a nice presentation on M-V-VM User Interface Patterns in Silverlight and WPF at last night's St. Louis .NET User Group meeting.

I would like to thank Dave Leininger for coming out and giving us a wonderful presentation on Business Intelligence. We had a good turn out and lively discussion. I definitely had a few preconceived notions of of BI smashed. The main one was when he said that most BI projects don’t use a data warehouse. On top of the information about BI we had some great discussion about general architecture topics. One of these was what is available from different vendors on how to make architecture decisions. ...

So today I finally got around to playing a bit more with Silverlight. F# has been taking most of my spare time and I felt I needed to branch out into something different for a day or two… Now, before I go into this post… my disclaimer… I am a Silverlight noob – in fact I have focussed most of my development time at normal applications so the whole internet is a bit of a mystery to me… that being said I had some very definite goals for this posting… Setup my server so that it would work with the services ...

For Issue 900, I wanted to do another "best of" and it's a little tricky. I can't do best of from 800 to 900 because it will be heavily weighted to the early posts. So what I did was best of for 2010 so far. I also did best of 2009 to put that one to bed. In the lists, Number 01 is the top hit, and they go on from there. Just a note to bloggers... if you reorganize your blog, don't break your links! ... there are a couple on these two lists that I had to go find, and that means that other links on ...
Intro One of the new additions in Expression Blend 4 is the Silverlight Databound Application Project template. I use that often when starting a new MVVM project. The template creates View and ViewModel folders and provides a good starting point for Model-View-ViewModel applications. The only downside is that this template is only available in Expression Blend and not in Visual Studio 2010. I’ve exported the project to a Visual Studio template to be able to use it in VS2010 too. Download The template ...

OK, Lots of confusion around this pattern. I am also trying to wrap my head around this pattern and wanted to present what I have learned so far as well as my favorite links on the subject.

A couple of days ago I was playing around with Silverlight 4. Amazing platform, especially since they now support multi-touch events. But before you can run, you’ve got to learn how to walk, right? So, in order to learn some of the new capabilities of the platform I decided to make an application to keep track of all my contacts. I know, there are numerous applications out there that can peform that task much better, but I didn’t want to create a usefull program, I just wanted to have a ‘real’ project ...

I did a recent post on implementing WPF with F#. Today I would like to expand on this posting to give a simple implementation of the MVVM pattern in F#. A good read about this topic can also be found on Dean Chalk’s blog although my example of the pattern is possibly simpler. With the MVVM pattern one typically has 3 segments, the view, viewmodel and model. With the beauty of WPF binding one is able to link the state based viewmodel to the view. In my implementation I have kept the same principles. ...
A few days ago I was programming on a personal project and hit a roadblock. I was applying the MVVM pattern and for some reason my view model was not updating the view when the state changed??? I had applied this pattern many times before and had never had this problem. It just didn’t make sense. So what did I do… I did what anyone would have done in my situation and looked to pass the blame to someone or something else. I tried to blame one of the inherited base classes, but it looked fine, then ...

More Adventures in MVVM In this post, I am going to explore how I prefer to attach ViewModels to my Views. I have published the code to my ViewModelSupport project on CodePlex in case you'd like to see how it works along with some examples.

I have used Prism to resolve ViewModels via Dependency Injection. ...

An interesting question from one of the MVVM Light users today: Is there an MVVM-friendly way to get a DataGrid’s SelectedItems into the ViewModel? The issue there is as old as the DataGrid (that’s not very old but still): SelectedItem (singular) is a DependencyProperty and can be databound to a property in the ViewModel. SelectedItems (plural) is not a DependencyProperty. Thankfully the answer is very simple: Use EventToCommand to call a Command in the ViewModel, and pass the SelectedItems collection ...
