当从.NET 3.5 w/wpf工具包升级到.NET 4.0时,为什么我的DataGrid样式会中断?

我刚刚将一个WPF项目从.NET 3.5转换为.NET 4.0。

我现在使用.NET 4.0 DataGrid 控件而不是WPF工具包 数据报ID 控制。从功能上讲,一切仍在工作,但我的风格没有按预期应用。

从下面的屏幕截图中可以看到,交替的行格式、填充、粗体标题等已停止工作。

之前(WPF工具包数据报)

在(.NET 4.0 DataGrid)之后

这是我的全部资源字典。

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Style x:Key="DataGrid_ColumnHeaderStyle" TargetType="DataGridColumnHeader">
        <Setter Property="FontWeight" Value="Bold" />
        <Setter Property="TextBlock.TextAlignment" Value="Center" />
        <Setter Property="TextBlock.TextWrapping" Value="WrapWithOverflow" />
    </Style>
    <Style x:Key="DataGrid_CellStyle" TargetType="DataGridCell">
        <Setter Property="Padding" Value="5,5,5,5" />
        <Setter Property="TextBlock.TextAlignment" Value="Center" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="DataGridCell">
                    <Border Padding="{TemplateBinding Padding}" Background="{TemplateBinding Background}">
                        <ContentPresenter />
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
    <Style TargetType="DataGrid">
        <Setter Property="ColumnHeaderStyle" Value="{StaticResource DataGrid_ColumnHeaderStyle}" />
        <Setter Property="CellStyle" Value="{StaticResource DataGrid_CellStyle}" />
        <Setter Property="Background" Value="White" />
        <Setter Property="AlternatingRowBackground" Value="#F0F0F0" />
        <Setter Property="VerticalGridLinesBrush" Value="LightGray" />
        <Setter Property="HeadersVisibility" Value="Column" />
        <Setter Property="SelectionMode" Value="Single" />
        <Setter Property="SelectionUnit" Value="FullRow" />
        <Setter Property="GridLinesVisibility" Value="Vertical" />
        <Setter Property="AutoGenerateColumns" Value="False" />
        <Setter Property="CanUserAddRows" Value="False" />
        <Setter Property="CanUserDeleteRows" Value="False" />
        <Setter Property="CanUserReorderColumns" Value="True" />
        <Setter Property="CanUserResizeColumns" Value="True" />
        <Setter Property="CanUserResizeRows" Value="False" />
        <Setter Property="CanUserSortColumns" Value="True" />
        <Setter Property="IsReadOnly" Value="True" />
        <Setter Property="BorderBrush" Value="#DDDDDD" />
        <Setter Property="HorizontalGridLinesBrush" Value="#DDDDDD" />
        <Setter Property="VerticalGridLinesBrush" Value="#DDDDDD" />
    </Style>
    <Style x:Key="DataGrid_FixedStyle" TargetType="DataGrid" BasedOn="{StaticResource {x:Type DataGrid}}">
        <Setter Property="CanUserReorderColumns" Value="False" />
        <Setter Property="CanUserResizeColumns" Value="False" />
        <Setter Property="CanUserResizeRows" Value="False" />
        <Setter Property="CanUserSortColumns" Value="False" />
    </Style>
</ResourceDictionary>

下面是一个用法示例(注意,样式设置为“datagrid_fixedstyle”):

<DataGrid
    Style="{StaticResource DataGrid_FixedStyle}"
    Grid.Column="0" Foreground="Black"
    SelectedIndex="{Binding SelectedParticipantIndex, Mode=TwoWay}"
    ItemsSource="{Binding Participants}">
    <DataGrid.Columns>
        <DataGridTextColumn Foreground="Black" Header="Participant" Binding="{Binding ParticipantId}" />
        ....
    </DataGrid.Columns>
</DataGrid>

注释

为了确保资源字典真正被使用,我将以下setter添加到 <Style TargetType="DataGrid">...</Style> :

<Setter Property="FontSize" Value="24" />

从下面的屏幕截图中可以看到,字体太大了,样式本身绝对不会被忽略。问题是许多设置由于某种原因未被使用或不起作用。

关于什么可能导致我的风格崩溃的理论?
