如何将不同样式应用于数据杂志列

Question

我是WPF的新手，我不知道如何为数据杂志的列使用两个不同的控制模板（该模板将始终具有2列）。这是datagrid的XAML：

<DataGrid x:Name="HomeSoftwareGrid"
          CanUserAddRows="false"
          ItemsSource="{Binding CollectedSoftwares}"
          AutoGenerateColumns="True"
          FontSize="15"
          ColumnWidth="*"
          IsReadOnly="True"
          AutoGeneratingColumn="OnAutoGeneratingColumn"
          CellEditEnding="OnCellEditEnding"
          HorizontalAlignment="Center"
          MaxWidth="600">
</DataGrid>

我正在使用属性AutogeneratingColumn删除特定列并编辑列的标题

private void OnAutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    PropertyDescriptor propertyDescriptor = (PropertyDescriptor)e.PropertyDescriptor;
    e.Column.Header = propertyDescriptor.DisplayName;
    if (propertyDescriptor.DisplayName == "Resources")
    {
        e.Cancel = true;
    }
    else if (propertyDescriptor.DisplayName == "SoftwareStatus")
    {
        e.Column.Header = "Software Status";
    }
    else if (propertyDescriptor.DisplayName == "SoftwareName")
    {
        e.Column.Header = "Software Name";
    }
}

这些是我要使用的内容模板，第一列的第一列，第二列明显是：d：

<!-- first column style -->
<Style TargetType="{x:Type DataGridCell}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataGridCell}">
                <ContentPresenter Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Center" />
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
<!-- second column style -->
<Style x:Key="SoftwareStatusDataGridColumn" TargetType="{x:Type DataGridCell}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataGridCell}">
                <Grid HorizontalAlignment="Center">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="Auto" />
                        <ColumnDefinition Width="Auto" />
                    </Grid.ColumnDefinitions>
                    <Rectangle x:Name="ImgPartially" Grid.Column="0"  Width="20" Height="20" Fill="Yellow">
                        <Rectangle.OpacityMask>
                            <VisualBrush Stretch="Uniform" Visual="{StaticResource appbar_warning}" />
                        </Rectangle.OpacityMask>
                    </Rectangle>
                    <ContentPresenter Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Center" />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

我该如何实现？

事件的 sender是datagrid，并且datagrid可以在其视觉树中找到单元格样式。然后，您可以单独分配该样式：

else if (propertyDescriptor.DisplayName == "SoftwareName")
{
    e.Column.Header = "Software Name";
    e.Column.CellStyle = (sender as FrameworkElement).FindResource("SoftwareStatusDataGridColumn") as Style;
}

<Style TargetType="{x:Type DataGridCell}">

此样式使用类型作为键，默认情况下将其分配给DataGridCells，无需从
