      <TextBlock Grid.Column="1" Margin="0,0,0,68">

       <Run Text="Psalm 24"/> 
      </TextBlock> 
     </Grid> 
    </Button>      
</phone:PivotItem> 

Answer 1

应该将一个容器元素内的两个按钮，诸如Grid或StackPanel：

<Grid> 
    //Buttons here 
</Grid> 

或

<StackPanel> 
    //Buttons here 
</StackPanel> 

Answer 2

试试这个。 PivotItem只允许一个子元素。这就是为什么你会得到错误。使用像Stackpanel或Grid这样的Container控件作为PivotItem的子项。

<phone:PivotItem CacheMode="{x:Null}" Header="Audio" Margin="41,30,8,-58"> 
<StackPanel> 
    <Button x:Name="button2" Content="hello" Height="22" Width="33"/> 
    <Button x:Name="playsound" HorizontalAlignment="Left" 
    VerticalAlignment="Top" Height="109" Width="256"> 
         <Grid Height="138" Width="293" RenderTransformOrigin="0.349,0.43"> 
          <Grid.ColumnDefinitions> 
           <ColumnDefinition Width ="110"/> 
           <ColumnDefinition Width ="110"/> 
          </Grid.ColumnDefinitions> 
          <TextBlock Grid.Column="0" Margin="0,0,0,68"> 
           <Run Text="יום ראשון&#10;"/> 
           <Run Text="Sunday"/> 
          </TextBlock> 
          <TextBlock Grid.Column="1" Margin="0,0,0,68"> 
          <Run Text="פרק כד&#10;"/> 
          <Run Text="Psalm 24"/> 
          </TextBlock> 
         </Grid> 
        </Button> 
    </StackPanel>     
</phone:PivotItem>
