WPF Datagrid與AlternatingRowBackground向上滾動和向下滾動時的滾動方式不同

Question

我向上滾動行顏色時，我有一個WPF（Win7上的4.0）數據網格，當我向下滾動顏色時數據正在移動，數據正在移動。 這是平常嗎？是否有可能擺脫這種奇怪的行爲？

電網XAML：

<DataGrid AutoGenerateColumns="True" 
         CanUserAddRows="False" 
         Grid.Row="0" Grid.Column="0" Name="grdData" 
         ItemsSource="{Binding Path=.}" SelectionMode="Single" 
         HeadersVisibility="All" 
         AlternatingRowBackground="LightGray" 
         /> 

注：我有其他問題關於滾動（WPF Datagrid scrolls up a bit when scrolled to end），但我不知道問題是否連接。

Answer 1

將EnableRowVirtualization="False"添加到您的數據網格中。

Answer 2

這觸發可與EnableRowVirtualization = 「真」

<DataGrid Name="dg" Style="{DynamicResource estiloDG}" MinRowHeight="40" GridLinesVisibility="None" 
      HorizontalGridLinesBrush="LightGray" VerticalGridLinesBrush="LightGray" 
      BorderBrush="Gray" BorderThickness="1" Foreground="#424242" 
      VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" 
      ItemsSource="{Binding ElementName=Me, Path=ItemsSource, Mode=OneWay}" x:FieldModifier="Private" 
      EnableRowVirtualization="True" 
      VirtualizingStackPanel.IsVirtualizing="True" 
      VirtualizingStackPanel.VirtualizationMode="Recycling" 
      CanUserAddRows="False" CanUserDeleteRows="False" CanUserReorderColumns="True" CanUserSortColumns="True"> 

    <DataGrid.RowStyle> 
     <Style TargetType="{x:Type DataGridRow}"> 
      <Style.Triggers> 
       <Trigger Property="AlternationIndex" Value="0"> 
        <Setter Property="Background" Value="White" /> 
       </Trigger> 
       <Trigger Property="AlternationIndex" Value="1"> 
        <Setter Property="Background" Value="#FFD0E8D0" /> 
       </Trigger>     
      </Style.Triggers> 
     </Style> 
    </DataGrid.RowStyle>
