我想在WPF应用程序（即触摸设备和台式机）上使用DataGrid。

在台式机上，DataGrid样式很好，但是在触摸设备上，当滚动/拖动DataGrid时，DataGridRow上会留下“鼠标悬停”的颜色。

如果可能，如何在滚动/拖动DataGrid时清除“鼠标悬停”颜色。

这是我的DataGrid的样式和模板代码。

    </Style>

    <Style x:Key="DataGridRowHeaderCellStyle" TargetType="datagridcell">
        ...
    </Style>

    <Style x:Key="DataGridColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}">
        ...
    </Style>
</ResourceDictionary>

还有我的使用代码。

<DataGrid Style="{StaticResource DataGridStyle}" Margin="8" ItemsSource="{Binding DataGridItems}" Height="400" Selectionmode="Single" SelectionUnit="FullRow">
    <DataGrid.Columns>
        <DataGridTemplateColumn Header="ID" SortMemberPath="Id">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Id}" Foreground="{StaticResource TextBrush}" FontSize="20" VerticalAlignment="Center" HorizontalAlignment="Left" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
        <DataGridTemplateColumn Header="data1" SortMemberPath="Data1">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Data1}" Foreground="{StaticResource TextBrush}" FontSize="20" VerticalAlignment="Center" HorizontalAlignment="Left" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
        <DataGridTemplateColumn Header="data2" SortMemberPath="Data2" Width="*">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Data2}" Foreground="{StaticResource TextBrush}" FontSize="20" VerticalAlignment="Center" HorizontalAlignment="Left" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

谢谢
