Question

我有一个按钮内容，我想在Silverlight应用程序中的UserControl上的多个按钮中使用。这是一个按钮的代码：

<Grid x:Name="LayoutRoot" Background="White">

    <Button Grid.Column="1" IsEnabled="{Binding PrivilegeChanged}" Height="24" Width="24">
        <Button.Content>
            <Canvas xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
                x:Name="UndoIcon" Width="16" Height="16" Clip="F1 M 0,0L 16,0L 16,16L 0,16L 0,0" UseLayoutRounding="False">
                <Canvas x:Name="Arrow_2" Width="16" Height="16" Canvas.Left="0" Canvas.Top="0">
                    <Path Width="17.0154" Height="17" Canvas.Left="-0.5" Canvas.Top="-0.499999" Stretch="Fill" 
                        StrokeLineJoin="Round" Stroke="#FF006432" Fill="#FF00C800" 
                        Data="F1 M 12.5819,16C 14.1685,12.7951 14.1052,6.14911 11.0969,4.25C 9.23816,3.07665 6.71915,3.4789 5.40404,5.25L 8.12669,8.25L 0,8.91667L 0,9.53674e-007L 3.17642,3.25C 4.16648,1.91667 5.52584,0.61155 7.13664,0.25C 9.85332,-0.359774 13.4395,0.629333 15.0571,2.91667C 17.402,6.23256 15.0026,12.7401 12.5819,16"/>
                </Canvas>
            </Canvas>
        </Button.Content>
    </Button>

</Grid>

如何在不删除按钮轮廓的情况下重复使用Button.Content？

最简单的方法是将按钮内容设计粘贴在自己的UserControl： -

中

<UserControl x:Class="SilverlightApplication1.MyButton"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
    <Canvas Width="16" Height="16" Clip="F1 M 0,0L 16,0L 16,16L 0,16L 0,0" UseLayoutRounding="False">
        <Canvas Width="16" Height="16" Canvas.Left="0" Canvas.Top="0">
            <Path Width="17.0154" Height="17" Canvas.Left="-0.5" Canvas.Top="-0.499999" Stretch="Fill" 
                        StrokeLineJoin="Round" Stroke="#FF006432" Fill="#FF00C800" 
                        Data="F1 M 12.5819,16C 14.1685,12.7951 14.1052,6.14911 11.0969,4.25C 9.23816,3.07665 6.71915,3.4789 5.40404,5.25L 8.12669,8.25L 0,8.91667L 0,9.53674e-007L 3.17642,3.25C 4.16648,1.91667 5.52584,0.61155 7.13664,0.25C 9.85332,-0.359774 13.4395,0.629333 15.0571,2.91667C 17.402,6.23256 15.0026,12.7401 12.5819,16"/>
        </Canvas>
    </Canvas>
</UserControl>

现在，您可以在需要此内容的地方创建此用户控件的多个实例： -

<UserControl x:Class="SilverlightApplication1.Test"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:local="clr-namespace:SilverlightApplication1"
    Width="400" Height="300">
  <Grid x:Name="LayoutRoot" Background="White">
        <StackPanel Orientation="Horizontal">
            <Button Grid.Column="1" IsEnabled="{Binding PrivilegeChanged}" Height="24" Width="24" Margin="2">
                <local:MyButton />
            </Button>
            <Button Grid.Column="1" IsEnabled="{Binding SomethingElseChanged}" Height="24" Width="24" Margin="2">
                <local:MyButton />
            </Button>
        </StackPanel>

    </Grid>
</UserControl>

通常您会创建一个Template来为您的按钮创建自定义布局。更快，更直接的解决方案是将内容设置为Style，并将样式应用于您需要的按钮。

使用您的内容定义样式：

<Window.Resources>
    <Style x:Key="ButtonArrowStyle" TargetType="Button">
        <Setter Property="Content">
            <Setter.Value>
                <Canvas xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
            x:Name="UndoIcon" Width="16" Height="16" Clip="F1 M 0,0L 16,0L 16,16L 0,16L 0,0" UseLayoutRounding="False">
                    <Canvas x:Name="Arrow_2" Width="16" Height="16" Canvas.Left="0" Canvas.Top="0">
                        <Path Width="17.0154" Height="17" Canvas.Left="-0.5" Canvas.Top="-0.499999" Stretch="Fill" 
                    StrokeLineJoin="Round" Stroke="#FF006432" Fill="#FF00C800" 
                    Data="F1 M 12.5819,16C 14.1685,12.7951 14.1052,6.14911 11.0969,4.25C 9.23816,3.07665 6.71915,3.4789 5.40404,5.25L 8.12669,8.25L 0,8.91667L 0,9.53674e-007L 3.17642,3.25C 4.16648,1.91667 5.52584,0.61155 7.13664,0.25C 9.85332,-0.359774 13.4395,0.629333 15.0571,2.91667C 17.402,6.23256 15.0026,12.7401 12.5819,16"/>
                    </Canvas>
                </Canvas>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>

然后定义一个按钮以使用该样式：

<Button Style="{StaticResource ButtonArrowStyle}"/>
