silverlight silverlight-2.0 expression-blend blend
I have Expression Blend 2, Service Pack 1, and cannot create a Silverlight 2 project. When I attempt to create a Silverlight 2 project, I get the following error:Blend cannot continue because a compatible Silverlight version could not be found.I installed Blend a few weeks ago, and service packed it yesterday. The order I did things is as follows:”old school” dev stack (VS 2005 Pro, SQL Server 2005 Express, SQL Server Mgmt Studio 2005, Infragistics, etc., all ages ago) Visual Studio 2008 Develop

I’ve got a problem using System.Windows.Interactivity.Interaction attached behavior class (from Expression Blend SDK 4). I’d like to define a pair of triggers for System.Windows.Window class in XAML Style element. But as the TriggersProperty field of System.Windows.Interactivity.Interaction class is private and there is no SetTriggers method in this class, I’ve got an error ‘Set property System.Windows.Setter.Property threw an exception. -> Value cannot be null. Parameter name: property’ when ru

wpf mvvm contextmenu prism blend
I have an entity view model. As there can be many entities in the UI, I have used a DataTemplate for representing an entity view model. This data template is used by the container control’s ItemTemplate property to render the entities. Please note this is not the conventional ListView/ListBox control. It is a Graph control with the edges and nodes being represented by the data templates. This said, each of the nodes are of different type and when the user right clicks, the context menu of the te

silverlight qt ria blend
I’m evaluating Silverlight for a RIA right now. A large amount of the Gui is to be designed by people without programming skills. Visually the application should be very appealing, animations, smooth transitions and so on are a big plus for us. Blend and Silverlight seem to be tailored very well to fit this requirement. However it does need the runtime which is somewhat acceptable for us but also a little disadvantage.So, do you know an mature Ria-like alternatives (similar ease of development,

wpf mvvm blend design-time
I have a view (usercontrol) that contains a listbox. At runtime the listbox will be populated with instances of another view (also a usercontrol). How can I populate the listbox in design-time (in Blend and Cider) with sample views that are themselves populated with sample data?

mvvm datatemplate datacontext blend
I’m currently using MVVM in a WPF project, all works very well. I have one Master view and many Detail views that I manage using a currentView property in my MasterViewModel. By using a datatemplate, I bind a view to a viewmodel. In fact, my master view has a contentcontrol whose content property is binded to my CurrentView property. When I set this currentview property to a viewmodel or another, it calls the corresponding template.My problem is that using this, my detail views doesn’t have expl

I have a data object (lets call it employee) who has many get/set methods to manipulate/store various parameters.This object is a singleton object used and referenced in many places in the WPF app.I am now building a view using Microsoft Expression Blend and would like to bind using Blend cool interface every of my control to the various method of my data object.When I try it, it will always create a static version of my employee data class.Is there a way to benefit from the nice user interface

I have created a user interface for my Silverlight application in Blend. This application is currently using some sample data that I created within Blend. I need to do something with this sample data at runtime.How do I access sample data that has been created in Blend at runtime?Thank you!

c# wpf blend visualstatemanager
I keep having this error sometimes in a particular case. It happens precisely when I am switching from a visual state to another. I assume it comes from a bad property animation but I wonder what are the conditions in which this exception occurs. Here is the error message:The runtime has encountered a fatal error. The address of the error was at 0x58e3ba0d, on thread 0xabc. The error code is 0x80131623. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code.

wpf xaml expression-blend blend
I have a large WPF application and am trying to use Blend 3 to speed up my UI design on some portions of it. The problem I run into is that I have different skins that the user can use, so I load the ResourceDictionaries and Converters at runtime at the Application level.Because of this, when I open a .xaml file in Blend, it can’t find the brushes/styles that are referenced, which means I don’t get the real look of the UI that I’m modifying.The only way that I have found to fix it is to add a r

Is it possible to use Blend to open any Windows Phone project on a Windows 7 dev machine? Of course, on Windows 7 you can’t install the Windows Phone 8 SDK. And when I try to open a Windows Phone 7.1 solution in Blend 2012, it crashes without explanation:Alternatively, is there any other way to extract control templates from WP controls?

wpf xaml microsoft expression blend
The main question is why do I have all these language folders being built to the output directory. If I set the reference to copylocal = false the folders are gone but then when I get to the view that has a behavior or a GoToState action the app crashes and says missing microsoft.expression.interactions. Any insight on this would be greatly appreciated. The goal is to have a manageable looking install directory that is not full of language folders that the app doesn’t even support and still use

expression-blend blend
I seem to be adept at making Expression Blend 4 crash at startup. The problem seems to be related to a deadlock initializing static managed and unmanaged variables as Blend first opens my solultion which has a mixture of unmanaged C++ and managed code projects. Blend crashes instantiating my ViewModel (I’m using MVVM Light in App.xaml, but I would think this isn’t really relevant). This page describes in detail how to detect and correct this potential deadlock: Initialization of Mixed Assembli

wpf xaml .net-4.0 expression blend
Below is the full XAML for the WPF application, no codebehind. On computers that have Expression Blend 4 installed, the following application works. However, on machines that do not have Blend, the application crashes. This is extremely simplistic, but it appears that the [i:Interaction.Behaviors] portion is what is causing the issue, which is a behavior from Blend that creates a smooth animation.<Window xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas

Edit: I don’t necessarily need a solution to this problem–rather I’d like to understand why it’s occurring. I don’t see why I should be getting the odd results below…Although this question is directed towards an issue I’m having with an HTML5 canvas application, I think the problem is less specific.I have an HTML5 canvas app that allows you to stamp images on the screen. These images are 32bit PNG’s, so I’m working with transparency. If I stamp a highly transparent image in the same location

algorithm graphics blend
In general, the “normal” blend mode equation looks like this:D = Sa * S + D * (1.0 – Sa)where D is destination color, Sa is source alpha and S is source color.Now, this works fine with fully opaque destination but I’d like to know how you would handle that with semi and fully transparent destination.When blending the source over a fully transparent destination, the source pixel (a pixel being color and alpha) will be unchanged and not blended like in the equation before, and if the destination b
