Question

我正在尝试创建类似于telerik numeric updown control的布局在内容面板网格内，但我无法在网格单元格中拉伸按钮。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中打开项目，然后右键单击Button并选择Edit Template-＆gt;编辑副本。

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

如果你没有Blend：

，这是最终的样式
