为什么Expression Blend 3不会记录我的色彩动画？ [英] Why Expression Blend 3 does not record my color animation?

问题描述

大家好，

我有一个非常简单的项目，里面有一个按钮和2个画笔

 
 <   Window  
  xmlns   =  " ;   http://schemas.microsoft.com/winfx/2006/xaml/presentation  "  
  xmlns：x   =  "   http://schemas.microsoft.com/winfx/2006/xaml   "  
  xmlns：d   =  "   http://schemas.microsoft.com/expression/blend/2008  "   xmln s：mc   =  "   http://schemas.openxmlformats.org/markup-compatibility/2006  "   mc：可忽略  =  "   d  "   xmlns：Microsoft_Windows_Themes   =  "   clr-namespace：Microsoft.Windows.Themes; assembly = PresentationFramework.Aero  "   xmlns：ic   =  "   clr-namespace：Microsoft.Expression.Interactivity.Core; assembly = Microsoft.Expression.Interactions  "   x：Class   =  "   ComboBoxTest.Window1  "  
 标题 < span style ="color：Blue;"> =  "   Window1  "  高度  =  "   300  "  宽度  =  "   300  "  >  
 <   Window.Resources  >  
 <   SolidColorBrush   x：键  =  "   OriginalColor  "  颜色  =  "  ＃FFEC7171  "   />  
 <   SolidColorBrush   x：Key   =  "   OverColor  < span style ="color：Black;">"   Color   =  "  ＃FFEC3737  "  < span style ="color：Blue;"> />  
 < /   Window.Resources  >  
 <  网格 >  
 <   Grid.RowDefinitions  >  
 <   RowDefinition  < span style ="color：Red;">高度  =  "   0.629 *  "   />  
 <   RowDefinition  高度  =  "   0.371 *  "   />  
 < /   Grid.RowDefinitions  >  
 <  按钮  x：名称  =  "  按钮 "  边距  =  "   64,48,90,56.056  "  内容  =  "  按钮 "  背景  =  "   {DynamicResource Ori ginalColor}  "   />  
 < /  网格 >  
 < /  窗口 >  
 
 

解决方案

您使用的是属性触发器吗？试试这个

< Style x：Key =" myStyle"   TargetType = " {x：Type按钮}" >  

......

  &NBSP;&NBSP; < Style.Triggers>  

  &NBSP; &NBSP; &NBSP; <触发器
属性 = "IsMouseOver"
值 = " True" >  

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; < Setter
属性 = "背景"
值 = " {StaticResource
OverColor }" />  

  &NBSP; &NBSP; &NBSP; < / Trigger>  

  &NBSP; < /Style.Triggers>  

< / Style>  

Hi all,

I have a very simple project with a button and 2 brushes inside

<Window
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero" xmlns:ic="clr-namespace:Microsoft.Expression.Interactivity.Core;assembly=Microsoft.Expression.Interactions" x:Class="ComboBoxTest.Window1"
  Title="Window1" Height="300" Width="300">
	<Window.Resources>
		<SolidColorBrush x:Key="OriginalColor" Color="#FFEC7171"/>
		<SolidColorBrush x:Key="OverColor" Color="#FFEC3737"/>
	</Window.Resources>
  <Grid>
  	<Grid.RowDefinitions>
  		<RowDefinition Height="0.629*"/>
  		<RowDefinition Height="0.371*"/>
  	</Grid.RowDefinitions>
		<Button x:Name="button" Margin="64,48,90,56.056" Content="Button" Background="{DynamicResource OriginalColor}"/>
	</Grid>
</Window>

解决方案

Hi,

Are you using property trigger, Try this

<Style x:Key="myStyle" TargetType="{x:Type Button}"> 

......

    <Style.Triggers> 
        <Trigger Property="IsMouseOver" Value="True"> 
            <Setter Property="Background" Value="{StaticResource OverColor}" /> 
        </Trigger> 
    </Style.Triggers> 
</Style>
