问题 I have a custom style for my 'default' Buttons, and also created a custom style for TextBlocks. If I remove the TextBlock style entirely, everything works fine, but once the TextBlock styling is added in for some reason the Button style is used on the Button's text 'default' state. It seems like some kind of inheritance is going on here but I can't see where in the msdn docs. What's going on? I'm using Expression Blend 4-- and also another odd thing is that the preview in Blend looks fine,

问题 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:/

问题 I am using several Blend behaviors and triggers on a silverlight control. I am wondering if there is any mechanism for automatically detaching or ensuring that OnDetaching() is called for a behavior or trigger when the control is no longer being used (i.e. removed from the visual tree). My problem is that there is a managed memory leak with the control because of one of the behaviors. The behavior subscribes to an event on some long-lived object in the OnAttached() override and should be

问题 I have created a kind of custom TextBox in Expression Blend. I have changed the fill of the background and border to a gradient, and added in a Shadow Effect. I've noticed that when I mouseover or focus my TextBox , some default behavior/(style?) of WPF takes over and my border is changed. I was wondering if there was anyway to prevent or stop WPF from changing my TextBox es style when I focus or mouseover it. Is this possible? 回答1: Does you custom style set the OverridesDefaultStyle property

问题 so I'm making my first windows phone app(in Expression Blend 4 as I am more of a designer than a coder), and I notice that by default, there are no transitions between pages. I google around, and all the solutions to creating these transitions seem to require setting RootFrame = new TransitionFrame(); in the App.xaml.cs file. Problem is, I can't find that file. Is it somewhere hidden or do I have to make it myself? Is there an easier way to do the transitions that I have missed? Thanks! 回答1:

问题 I've got a problem using System.Windows.Interactivity.Interaction attached behavior class (from Expression Blend SDK 4).
