Question

将一个storybord移动到资源字典以便在我的enitre应用程序中使用时遇到问题。

基本上想在多个用户控件上使用相同的故事板。

Resource Dicitionary

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Storyboard RepeatBehavior="Forever" x:Key="AnimateWidth">
<DoubleAnimation Storyboard.TargetProperty="Width" From="1" To="250" Duration="0:0:2" BeginTime="0:0:0" FillBehavior="Stop" />
</Storyboard>
</ResourceDictionary>

用户控件

<UserControl x:Class="Toolset.WMIControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:View="clr-namespace:Toolset"
             Name="WmiControl_UserControl"
             Loaded="UserControl_Loaded"

             mc:Ignorable="d" 
             >
<UserControl.Resources>
        <ResourceDictionary x:Key="Animations">
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="AnimationStyles.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>


    </UserControl.Resources>

 <DockPanel Name="DockPanel1" Style="{StaticResource Animations}">
            <DockPanel.Triggers>
            <EventTrigger RoutedEvent="Loaded">

                <BeginStoryboard Storyboard="{Binding AnimateWidth, Source={StaticResource Animations}}"/>
            </EventTrigger>
        </DockPanel.Triggers>
    </DockPanel>

不确定我在哪里出错了。任何帮助，将不胜感激。获取错误“必须在此触发器操作执行之前引用一个Storyboard对象。

</DockPanel>

Answer 2

回答了我自己的问题..

这是您使用另一个文件中的ResourceDictionary动画的方法。不使用C＃，因为你没有设置视图样式，所以将它保留在视图中

 <ResourceDictionary x:Key="Animations">
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="AnimationStyles.xaml"/>
            </ResourceDictionary.MergedDictionaries>
  </ResourceDictionary>

       <DockPanel x:Name="Simple_Mode" DockPanel.Dock="Top" 
                  HorizontalAlignment="Left" 
                  ScrollViewer.HorizontalScrollBarVisibility="Hidden" 
                       Resources="{StaticResource Animations}" 
                       >
                <DockPanel.Triggers>
                    <EventTrigger RoutedEvent="Loaded">
                        <BeginStoryboard Storyboard="{StaticResource AnimateWidth}"/>
                    </EventTrigger>
                </DockPanel.Triggers>
        </DockPanel>
