ScrollViewer XAML : MouseWheel不工作

Question

我正在为一个小企业开发一个应用程序，并且我对水平滚动查看器有一个问题。

水平ScrollViewer出现在屏幕上，但鼠标轮不工作。

我有一个XAML代码：

<ScrollViewer ScrollViewer.ZoomMode="Disabled" HorizontalScrollMode="Auto" HorizontalScrollBarVisibility="Auto" ScrollViewer.IsHorizontalScrollChainingEnabled="True" VerticalScrollBarVisibility="Disabled" Margin="0,130,0,0" VerticalContentAlignment="Stretch" ManipulationMode="All">
       <Grid Width="1000" HorizontalAlignment="Left" >
           <Grid.ColumnDefinitions>
               <ColumnDefinition Width="250*" ></ColumnDefinition>
               <ColumnDefinition Width="250*"/>
               <ColumnDefinition Width="250*"/>
               <ColumnDefinition Width="250*"/>
           </Grid.ColumnDefinitions>
           <Grid.RowDefinitions>
               <RowDefinition Height="65*" />
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
               <RowDefinition Height="45*"/>
           </Grid.RowDefinitions>
           <TextBlock Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="2" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="20,0,0,0" Text="Στοιχεία Πελάτη" FontSize="50"></TextBlock>

           <TextBox Grid.Column="1" Grid.Row="6" Height="30"></TextBox>
           <TextBox Grid.Column="3" Grid.Row="1" Height="30"></TextBox>
           <TextBox Grid.Column="3" Grid.Row="2" Height="30"></TextBox>
           <TextBox Grid.Column="3" Grid.Row="3" Height="30"></TextBox>
           <TextBox Grid.Column="3" Grid.Row="4" Height="30" VerticalAlignment="Center"></TextBox>
           <TextBox Grid.Column="3" Grid.Row="5" Grid.RowSpan="4" AcceptsReturn="True" TextWrapping="Wrap" ScrollViewer.VerticalScrollBarVisibility="Visible"/>
           <Button Grid.Column="3" Grid.Row="9" Content="Αποθήκευση" FontSize="22" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"></Button>
      </Grid>
   </ScrollViewer>

有什么不对的？

Answer 1

除了确保您的滚动查看器以固定的宽度显示，因此在查看器本身内启用滚动(目前看来，查看器不需要滚动来显示内容)，将查看器声明更改为以下内容。

 <ScrollViewer 
    Style="{StaticResource HorizontalScrollViewerStyle}"
    ScrollViewer.IsHorizontalScrollChainingEnabled="True" 
    Margin="0,130,0,0" 
    VerticalContentAlignment="Stretch" 
    ManipulationMode="All">

样式应该在StandardStyles.xaml中定义，但是如果您不使用该文件，定义如下。

<Style x:Key="HorizontalScrollViewerStyle" TargetType="ScrollViewer">
    <Setter Property="HorizontalScrollBarVisibility" Value="Auto"/>
    <Setter Property="VerticalScrollBarVisibility" Value="Disabled"/>
    <Setter Property="ScrollViewer.HorizontalScrollMode" Value="Enabled" />
    <Setter Property="ScrollViewer.VerticalScrollMode" Value="Disabled" />
    <Setter Property="ScrollViewer.ZoomMode" Value="Disabled" />
</Style>

尝试缩小网格宽度，然后检查。通常，如果网格宽度很大或“自动”，内容会自动缩放以适应，因此滚动查看器无法工作。
