It maps mouse DoubleClick on an image into a command in the ViewModel to display the properties. The project structure is pretty much like all the other samples I’ve blogged about – I’m trying to keep to a consistent model: Service Registration. First, note that it registers the standard services – that’s something I always do, even if I don’t anticipate needing them all, it doesn’t hurt to have them there. par ?? par ?? Mark's Blog of Random Thoughts - Friday, February 5, 2010 MVVM: Binding RadioButton groups A question I got recently was how to manage Radio Buttons with bindings – in this instance, the sample code was trying to map a single value to a set of Radio Buttons based on an enumeration set. The original implementation was using a Value Converter to compare the “bound” value with the enumeration value expected for that radio button choice – if it was equal then the converter returned true, otherwise false. This happens because the selected Radio Button itself tells the group to uncheck all the others. cf0 cf1 ///cf3 Game they like to playpar ??cf0 Mark's Blog of Random Thoughts - Friday, January 29, 2010 MVVM: Rename TreeView nodes I know I said I was going to cover some services next, but I got a request last night to show how to rename TreeView nodes (ala Explorer) using the MVVM pattern in WPF. First, the idea is we want to be able to double-click on the text portion of the TreeViewItem and have it allow us to type in a new name, replacing the current text. This involves changing the visual template out (from a TextBlock to a TextBox ) and then detecting that the edit is complete. First, let’s add a property to indicate whether we are in “editing” mode or not. Mark's Blog of Random Thoughts - Thursday, January 28, 2010 | | The Best from Mark's Blog of Random Thoughts | MORE | | WPF MVVM Helper Library (WPF + MVVM = testability) When teaching WPF, I always introduce students to MVVM as part of the Essential WPF class, it's an incredibly useful pattern that really separates the UI from the code behind behavior. One of the things I give the students is a library to do MVVM - I also use it in my consulting work. With all the focus on it lately, I figured maybe it's time to release it to the public. that I tend to use a lot. These classes tended to evolve with new functionality (either due to necessity, or because a good idea occurred to me or someone else). file -. Mark's Blog of Random Thoughts - Friday, April 17, 2009 WPF Data Providers It ships with two out of the box: ObjectDataProvider: allows you to execute binding expressions against an object and it's methods. side note here is that you could write your own custom data provider if you needed to, although if the data is exposed through a.NET object, then the ObjectDataProvider is probably sufficient. However, this is the 21st century and so we want to avoid coding as much as we can and utilize the underlying framework support instead! In this case, we want to see everything under the node "taxrecords" which is the root of the document. Mark's Blog of Random Thoughts - Wednesday, January 17, 2007 Part 3: Shifting focus to the first available element in WPF We've seen how to programatically control focus and that's all great stuff, but one thing I like to do with WPF is see how much of the repetitive or UI-specific code I can move into the XAML and keep out of the code behind. We can use the FocusManager.FocusedElement property to shift focus in XAML but it only works when the element exists in the main XAML file. In my specific case, I have a wizard-style application which utilizes a TabControl to move between the pages. We won't be able to find the child in the visual tree if the parent isn't yet loaded.

This happens to be one of the most obviously changed things in Orcas - the dialog presented is a more professional version than what was supplied with the original WCF CTP for VS.2005: The "Discover" button above can locate IIS-hosted web services (not Self Hosted however) and it now shows operations directly which is pretty cool. The bottom section - "Compatibility" allows you to generate a web service proxy using that original WS technology. You might be asking - "Why would I want to generate one of those? The best part is the "Advanced" button though. - Focusing on WPF: How to deal with Focus() in the WPF world
Recently I was involved in a project where we needed to build a multi-step input application where each step showed progress and you could proceed forward and backward through the pages. looked at the Navigation support in WPF (which is nice) but ultimately decided to model it around a styled TabControl – each page being a tab and the progress noted through the custom TabItem visuals across the top. Those that are new to WPF might be surprised that it does not assign initial focus to any particular child control – you must deliberately click or tab into a control to give it focus. - Part 3: Shifting focus to the first available element in WPF

| The Latest from DevelopMentor | MORE | | Unit testing code depending on the ASP.NET #WebApi HttpClient 'In a previous post I showed how to unit test an ASP.NET WebAPI Controller. In this case the client application contains the following class to load books from the REST WebAPI controller: 1: public class BooksClient. This class uses the HttpClient to request the data from the service and extracts the books from the body before returning them. If we want to test this class we need to pass in an HttpClient object. This HttpMessageHandler is used as the pipeline to send requests and we can completely replace this with our own implementation. 14: {.

In these examples I uses a really simple single element to bind to. However in lots of business cases you really need to display a list of repeating elements. Fortunately this is really easy to do. Take a look at the simple list of people below. 2: 3: $scope.people = [.

There are many different options to choose depending on your platform and use-cases. Key features : Complete (albeit command-line only) access to MongoDB.

| The Best from DevelopMentor | MORE | - How to improve a team's velocity?
By way of wrapping up my velocity mini-series ( Two ways to fill and iteration , Filling an iteration too well , and Velocity Targeting and Velocity Inflation ) I’m going to end with some advice on how to improve a team’s velocity. Over time these add up to big improvements. To use economic logic: this is about improving the supply-side. The supply-side argument (largely monetarist) suggests the way to solve unemployment is not to increase demand (Keynes style) but to loosen and liberalise the labour market. But back to software.

So I ended up running Windows Cerificate Services which proved to be an easy to use, robust solution. just had to rebuild my Test CA (on Hyper-V) so I thought I'll document the important steps (for self-reference and whoever might be interested). They usually expire on the very day where you have to do an important demo. Now by default there is an entry pointing to the CA's Netbios name. better solution is to create a revocation list once, and store that at a publicly available location. Next you have to publish a CRL. Set it to e.g. five years. www.leastprivilege.com - Thursday, August 14, 2008 - How to get started with Knockout.js
Once you get into doing more client side JavaScript code with business applications and REST services you are going to run into the question of how to construct the client side HTML required to show the data to the users. Using jQuery Assuming most people are going to be using jQuery on the client you might start with some jQuery code to generate HTML. And in all likelihood the actual HTML that needs to be generated will be quite a bit more complex. The next step people tend to take is using templates. click( function () {. $.getJSON( The Problem Solver - Monday, February 6, 2012 - How to data bind to collections using Knockout.js
I showed to to get started with the awesome Knockout.js In this post I am going to show how easy it is to load a collection of items from a REST service and data bind to the complete collection. To data bind to collections of data Knockout supports the foreach data binding. In the example below I am using an html to display a list of books. The has the data binding attribute so its contents are going to be repeated for each item in the collection being used, books in this case. and controlling updates using Knockout.js Title.
