As I did after the Silverlight 2 & 3 releases, I thought it would be a good idea to review the bugs that I have submitted, to see what progress is. If you haven't already downloaded the Silverlight 4 beta, you can get all the information you need about this release from Tim Heuer's blog: http://timheuer.com/blog/archive/2009/11/18/whats-new-in-silverlight-4-complete-guide-new-features.aspx Thankfully bug fixing progress is much better than I expected this time. Five bugs are fixed, althoug ...

As mentioned in my previous post. I have developed FlowDocument viewers for Silverlight which are intended to be API compatible with the WPF FlowDocument viewers. FlowDocuments give you the ability to display rich text content and are a feature of WPF. Unfortunately this functionality is not currently available in Silverlight. When building the Virtual Tour Viewer I needed to flow documents, because the WPF version already displayed its text using flow documents. The solution was to build my ow ...

ComponentArt are currently holding a competition to find the best Silverlight application. The community can vote for their favourite application and they will then be judged by some of the most respected people in the Silverlight community. The winner gets $10,000 US! You can see and vote for all entrants here: http://www.componentart.com/community/competition2009/ Over the past couple of weeks I've spent a lot of time redesigning the Virtual Tour viewer I have described in p ...

Unfortunately the dataform that was shipped with Silverlight 3 RTW (in the Toolkit) was massively changed from the beta version, and as a result has a number of bugs that were not there during the beta. To find these bugs create a new project using the business application template, and run it. Click login, type some text into Username and then click OK and you will see the following screen: You will note that there are two problems with this screen: 1. the first one is that the data f ...

As I did after the Silverlight 2 release, I thought it would be a good idea to review the bugs that I have submitted, to see what progress is. It's taken me a while to get this done because I've been busy with other things. Four of the bugs are fixed. Unfortunately, the Silverlight team are very poor at communicating the status of bugs - often bugs will be closed then opened and then closed again and there's often never any explanation as to whether the bug is ever going to be fixed. The ...

Update: I'd forgotten to update the sample that goes along with the download. It has now been updated to support the .net RIA services July CTP. I’ve received a couple of requests in the past few days asking if there will be an update to the URI mappers (Updates to custom routing using the Uri Mapper in Silverlight 3 and Displaying a login dialog based on page attributes in Silverlight 3) that work with the Silverlight 3 RTW & .net RIA services July CTP. The CustomUriMapper works ju ...

In my previous post on Silverlight multi-binding support I mentioned that theoretically it should be possible to use the Silverlight multi-bindings in WPF. Unfortunately the practicalities of single sourcing between WPF and Silverlight are not always as simple as you might expect, and this case was no different! Given that WPF already has its own multi-binding functionality, why would you want to use the Silverlight attack? You only really want to do this when you want to have source code compa ...

Hopefully some of you have picked up the recent blog post by Colin Eberhardt, entitled Silverlight MultiBindings, How to attached multiple bindings to a single property. It provides an excellent basis for multi-binding support in Silverlight until they actually get on with it and become more compatible with WPF and have multi-binding directly built in! However, when I came to use the multi-binding support, there was a limit with Colin's original design that you can only have one multi-bin ...

Update: The latest version of the code is available for download here. This page has been re-written for the .net ria Services July CTP. One of the feature requests I described in my post Issues with the Silverlight Navigation architecture was the ability to use an attribute to declare the required roles to display a particular page. e.g: [RequiresAuthentication] public partial class CategoryPage : Page Unfortunately this is not part of Silverlight 3, so I set about implementing it mys ...

Update: this code is now available for download, including a project file here. In my previous post regarding custom URI routing using the URI mapper in Silverlight 3, I described a problem where if you wish to cancel the navigation, to display a dialog for example, returning null from the UriMapper can in some scenarios cause an exception. After some discussions with Austin Lamb, a developer on the Silverlight team, it was clear that the solution I had chosen to cancel navigation was not ...

In my last post, I described some of the ways I was able to use the Silverlight URI mapping architecture to provide more customized routing. However, there are a few problems with the navigation/URI mapping architecture that I haven't been able to find ways to work around. Setting a title One of the major problems I've encountered is getting the title (in the browser's title bar) to be set. There is a field in the Page class called title. So you would think would be relatively simple. It appe ...

Update: see the latest version of this code here. The new navigation architecture in Silverlight 3 is very exciting as it substantially improves the viability of Silverlight for use replacing html websites (except for the lack of a hyperlink class, which I can't understand not being included in Silverlight 2). I'm currently developing a website which will be running Silverlight 3 and have discovered some interesting issues with the URI mapping architecture as it currently stands in the beta. T ...

Bea Stollnitz has been running a series on her blog, describing how to expand items in the tree view, in both WPF and Silverlight, but much of it was extraordinarily complicated. For the project I'm working on with Silverlight and the .net RIA services I needed one of my tree views to appear completely expanded initially. There's a lot of code on Bea’s blog, but I cut down what I needed to this new tree view control. You can use it in your application and your tree will i ...

I'm currently working a very interesting project using Silverlight 3 and the new .net RIA services. Basically we're building the whole e-commerce type website using Silverlight 3. If you don't have Silverlight 3 installed you'll be presented with HTML versions of the pages that you can browse and if you need to login or use any of the interactive features then we will require you to install Silverlight 3. I still have concerns about the install base of Silverlight. The site is entirely focused ...

I'm sorry it has taken so long, but the beta version of the virtual tour viewer for WPF is now available. It demonstrates the splash screen that we have developed along with targeted commands, the Silverlight WPF library and the WPF panorama library we have written. To download the tours, click here. The available tours are all evaluation versions, the full versions can be purchased from our website www.palacevirtualtours.com It has taken longer than expected because we hav ...

If you are like me, when you first heard about Silverlight, you thought this is fantastic, the WPF application you just developed can be taken, and with a few changes to support asynchronous loading, you've got an Internet accessible application! Well, think again! That's not how it works. Although it is supposed to be a subset of WPF, there is a lot of core WPF functionality that is either not there or operates fundamentally differently under Silverlight. Most Microsoft people reco ...

Scott Guthrie today announced a number of new features that will be available in Silverlight 3, available next year. In addition to the previously announced H.264 video support, there is a substantial surprise in that they have announced 3D and GPU hardware acceleration support. I hadn't expected this until after version 3. He also announced richer data binding support which frankly could mean anything. Hopefully it means DependencyProperties and element binding work the same as in ...

Whilst building the WPF version of our virtual tour software we came across a situation where routed commands, the built in command infrastructure in WPF would not actually achieve what we wanted. The way routed commands work is that they work their way up the visual tree trying to find a CommandBinding from someone who was interested in processing that command. Unfortunately in a number of situations in the viewer that is not the behaviour that we want. Sometimes you could be ...

As I mentioned in my post Silverlight 2 RTW Bugs data binding is basically broken in Silverlight 2. I wasn't at the time entirely sure exactly what the reason was, but I have now discovered it (or part of it). It turns out that custom Dependency Properties, on which I rely for my data binding do not actually notify bindings of a change in state. This is of course completely inconsistent with WPF and makes maintaining code between Silverlight in WPF even more difficult ...

The Silverlight 2 release came out today. The first thing I had to do was to revisit all the bugs that I reported during the release candidate period. They were all reported via the Microsoft connect site, but very oddly they were closed by Microsoft with the reason being External. Normally when I report a bug that is fixed they will be marked as fixed, so I assumed that they had not been fixed. Unfortunately I was correct. Update: it has been pointed out to me that b ...

Silverlight version 2 has been released today! If you've been stuck on a desert island somewhere over the past two years you won't know that Silverlight is a version of the .net framework designed to run in your web browser. It utilises a cut down version of the WPF XAML specification to provide the user interface. I have been building both a WPF and Silverlight version of the virtual tour software we produce (www.palacevirtualtours.com). Despite Microsoft claiming ...
