我正在尝试在内容面板网格内创建一个类似于 Telerik 的数字上下控件的布局， 但我无法让按钮在网格单元格中拉伸。我怎样才能做到这一点？

<Grid x:Name="ContentPanel" 
      Grid.Row="1" 
      Margin="12,6,12,0" 
      Height="70">
   <Grid.ColumnDefinitions>
       <ColumnDefinition Width="*"/>
       <ColumnDefinition Width="70"/>
       <ColumnDefinition Width="70"/>
   </Grid.ColumnDefinitions>

   <Border Grid.Column="0"
           BorderThickness="2"
           BorderBrush="{StaticResource PhoneForegroundBrush}">
      <TextBlock Text="Count" 
                 VerticalAlignment="Center" 
                 Margin="12"/>
   </Border>
   <RepeatButton Grid.Column="1" 
                 Content="-"/>
   <RepeatButton Grid.Column="2" 
                 Content="+"/>
</Grid>

这是因为Button和RepeatButton控件具有默认边距。

您可以做的是编辑控件模板的副本并手动将Margin属性设置为 0。

为此，您需要在 Blend 中打开您的项目，然后右键单击按钮并选择编辑模板-> 编辑副本。

然后您必须将 Border 控件的 Margin 属性从{StaticResource PhoneTouchTargetOverhang}更改为 0。

这是生成的样式，如果您没有 Blend：

<Style TargetType="RepeatButton">
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}"/>
            <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
            <Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/>
            <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiBold}"/>
            <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMedium}"/>
            <Setter Property="Padding" Value="10,5,10,6"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="RepeatButton">
                        <Grid Background="Transparent">
                            <VisualStateManager.VisualStateGroups>
                                <VisualStateGroup x:Name="CommonStates">
                                    <VisualState x:Name="Normal"/>
                                    <VisualState x:Name="MouseOver"/>
