问题 In blend 4 i often open a resource dictionary (i.e. "Generic.xaml") by clicking the "resources" tab (next to the property tab on the right pane), navigate to a resource and click on its icon to edit it in the designer. In blend for visual studio 2012 i can't seem to find the resources tab? How am i then able to edit resources in resource dictionaries? 回答1: I'm assuming this is a XAML project. Is the Window open? Main toolbar -> Window -> Resources... is that checked? If not, check that. 回答2:

问题 I'm aware this is the same issue as raised in "PageFunction is not supported in a Windows Presentation Foundation (WPF) project" 2012 - however, I'm unsure as to how to apply the workaround mentioned there, and thought it may be more appropriate to raise this as a separate question. Apologies in advance if this is against the site ethos. To summarise the problem: I have a C# Visual Studio 2010 WPF project that's a couple of years old, which I'm now trying to open in Visual Studio 2012.

问题 We can apply only one effect to an element. Is there any way to apply multiple effects simultaneously to an element? like both DropShadowEffect as well as the BlurEffect ? Google did not help me much. Any suggestions? 回答1: I once experienced the same problem; I had to apply a BlurEffect as well as a DropShadowEffect to an image. What I did was this: I applied the BlurEffect to the Image and put that Image into a Grid (which itself is lookless) onto which I could apply the DropShadowEffect:

问题 I am building an application in VS2010 with wpfToolkit 3.5 as referenced assembly. I tried to add some VisualStates from ExpressionBlend 4 and I am getting the following error when I am trying to build the project.

问题 We are trying out Visual Studio 2008 and Expression Blend on a new project. The goal is to clearly define the role of the developer and designer as separate, but reap the benefit of the developer being able to directly consume the XAML produced by the designer. For the most part this has worked great, and I really like the possibilities. One difficulty we have come across though is designing against DataBindings. In many cases, the GUI does not populate rows, or other data structures unless

问题 Here is what I have so far: <Image Source="{Binding ImageSource"} /> <Button Content"Text" ImageSource="path/image.png" /> I know something isn't right here. I guess I can't see where ImageSource is defined. I have several of these buttons and just want to have a unique image for each one. I have a button template that I am using and it works great for the text. <Label Content="TemplateBinding Content" /> Thanks for all your help! 回答1: In your case, it can be very easy! Add the images as

问题 I have created a simple Expression Blend 4 project with a DatePicker. I edited the template for the DatePicker, including its DatePickerTextBox, changing the watermark text from "Select a date" to "dd/mm/yyyy". The resulting XAML in Blend applies a style to the original DatePicker, and this style is stored as a resource in Window.Resources.
