Question

我在c＃WPF 3.5 .NET应用程序中使用了按钮

<Button Height="23" x:Name="btnImportKvf" Width="75" Click="btnImportKvf_Click" IsEnabled="True" ToolTip="Click to Import" Content="Import KVF" />

enter image description here

我的按钮样式模板在ResourceDirectory App.xaml中应用，如下所示

<ResourceDictionary

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

  <!-- Focus Visual -->

  <Style x:Key="ButtonFocusVisual">
    <Setter Property="Control.Template">
      <Setter.Value>
        <ControlTemplate>
          <Border>
            <Rectangle 
              Margin="2"
              StrokeThickness="1"
              Stroke="#60000000"
              StrokeDashArray="1 2"/>
          </Border>
        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>

                            <Setter Property="Background" TargetName="border" Value="{DynamicResource GlowBrush}"/>
                        </Trigger>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Foreground" Value="{StaticResource GlyphDarkBrush}" />
                            <Setter Property="Background" TargetName="border" Value="{DynamicResource GlowBrush}"/>
                        </Trigger>
                        <Trigger Property="IsCancel" Value="False"/>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="Background">
            <Setter.Value>
                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                    <GradientStop Color="#FFFFFFFF" Offset="0"/>
                    <GradientStop Color="#FFEAEBF0" Offset="0.9"/>
                </LinearGradientBrush>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

现在我在我的项目中进行本地化，所以在更改像法语这样的语言时，Button文本会变得很大而不是按钮宽度，所以我想要按钮样式中的自动文本调整。并在工具提示中显示全文。

此外，我还有第二种带有图像和文字的按钮。

<Button Name="btnRefresh" Click="btnRefresh_Click" Width="69" ToolTipService.ToolTip="Click To Refresh" FontSize="11" Content="Refresh">
        <Image Source="../Images/Refresh.png" Width="18" Height="13" />
    </Button>

enter image description here

我也想用这个按钮应用相同的风格。

那么可以在相同的样式模板中执行此操作吗？

请帮我解决这个问题。在此先感谢。

为此，您需要将样式中的ContentPresenter更改为Textblock，并将其Text绑定到您的内容。

如果你用这些东西替换某些东西，你应该可以根据需要设置文本修剪。

<ControlTemplate TargetType="{x:Type Button}">
    <Border x:Name="border" 
            Background="{DynamicResource BackgroundNormal}" 
            BorderThickness="1,1,1,2" 
            CornerRadius="4,4,4,4" 
            BorderBrush="{DynamicResource GlyphDarkBrush}">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="0.507*"/>
                <RowDefinition Height="0.493*"/>
            </Grid.RowDefinitions>
            <Border Opacity="0" 
                    HorizontalAlignment="Stretch" 
                    x:Name="glow" 
                    Width="Auto" 
                    Grid.RowSpan="2" 
                    CornerRadius="4,4,4,4" 
                    Background="{StaticResource GlowBrush}"  />
            <TextBlock Text="{TemplateBinding Content}" 
                       TextTrimming="WordEllipsis" 
                       SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" 
                       HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                       Margin="{TemplateBinding Padding}" 
                       VerticalAlignment="{TemplateBinding VerticalContentAlignment}" 
                       Grid.RowSpan="2"/>
            <Border HorizontalAlignment="Stretch" 
                    Margin="0,0,0,0" 
                    x:Name="shine" 
                    Width="Auto" 
                    CornerRadius="4,4,0,0" 
                    Background="{DynamicResource ShineBrush}"/>
        </Grid>
    </Border>
   ...
</ControlTemplate>

编辑：关于你问题的第二部分。您显示的最后一段代码无法正常工作，因为您将按钮的内容设置了两次（我认为它实际上并未编译）。

执行您尝试实现的目标的最简洁方法是定义自定义Control类，如here所述。

A＆＃34;不太干净＆＃34; hack可能是使用Button的Tag字段来存储图像源URI，如下所示：

<Button Name="btnRefresh" 
        Click="btnRefresh_Click" 
        Width="69" 
        ToolTipService.ToolTip="Click To Refresh" 
        FontSize="11" Content="Refresh"
        Tag="../Images/Refresh.png" Width="18" Height="13" />

然后以你的风格检索它。此Grid替换了先前解决方案中的Textblock：

<Grid Grid.RowSpan="2">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Image Grid.Column="0"
           Source="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Tag}" />
    <TextBlock  Text="{TemplateBinding Content}" 
                Grid.Column="1"
                TextTrimming="WordEllipsis"
                SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" 
                HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                Margin="{TemplateBinding Padding}" 
                VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</Grid>

here解释了绑定略有不同的原因。

但是，再次创建一个包含图像和文本的自定义按钮可能是最干净的方法！

使用自动Texttrimming with Image或仅用于本地化的文本来设置WPF按钮内容的样式
