C# 在绑定属性上设置WPF DataGrid行的样式

我有一个绑定到EventRecords列表的数据网格。EventRecord对象上有一个属性

IsAutoEvent

。我正试图根据此属性是否为真来设置行的背景色样式，但DataContext并没有像我预期的那样设置

<DataGrid Name="EventGrid" IsReadOnly="True" AutoGenerateColumns="False" ItemsSource="{Binding Events}" SelectedItem="{Binding SelectedEvent}" CanUserAddRows="False" SelectionMode="Single" SelectionUnit="FullRow">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Start Time"  Width="Auto" Binding="{Binding StartTime, StringFormat={}{0:hh:mm:ss}}" CellStyle="{StaticResource CenterAlignedDataGridCell}"/>        
        <DataGridTextColumn Header="Description" Width="*" Binding="{Binding Description}" CellStyle="{StaticResource CenterAlignedDataGridCell}"/>
        <DataGridTextColumn Header="Comments" Width="*" Binding="{Binding Comment}"/>        
    </DataGrid.Columns>
    <DataGrid.RowStyle>
        <Style TargetType="{x:Type DataGridRow}">            
            <Style.Triggers>
                    <DataTrigger Binding="{Binding Path=IsAutoEvent}">
                        <Setter Property="Background" Value="Red"/>
                    </DataTrigger>
            </Style.Triggers>            
        </Style>
    </DataGrid.RowStyle>
</DataGrid>

目前，这没有任何作用。我不认为datacontext是正确的，因为在

DataTrigger

下，

{Binding}

显示视图的属性（例如MainViewModel），而不是DataGridRow（例如EventRecord），正如我所料

有什么想法吗？

您没有将

值

放在

数据触发器上

               <DataTrigger Binding="{Binding Path=IsAutoEvent}" Value="True">
                    <Setter Property="Background" Value="Red"/>
                </DataTrigger>

<DataGrid Name="EventGrid" IsReadOnly="True" AutoGenerateColumns="False" ItemsSource="{Binding Events}" SelectedItem="{Binding SelectedEvent}" CanUserAddRows="False" SelectionMode="Single" SelectionUnit="FullRow">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Start Time"  Width="Auto" Binding="{Binding StartTime, StringFormat={}{0:hh:mm:ss}}" CellStyle="{StaticResource CenterAlignedDataGridCell}"/>        
        <DataGridTextColumn Header="Description" Width="*" Binding="{Binding Description}" CellStyle="{StaticResource CenterAlignedDataGridCell}"/>
        <DataGridTextColumn Header="Comments" Width="*" Binding="{Binding Comment}"/>        
    </DataGrid.Columns>
    <DataGrid.RowStyle>
        <Style TargetType="{x:Type DataGridRow}">            
            <Style.Triggers>
                <DataTrigger Binding="{Binding Path=IsAutoEvent}" Value="True">
                    <Setter Property="Background" Value="Red"/>
                </DataTrigger>
            </Style.Triggers>            
        </Style>
    </DataGrid.RowStyle>
</DataGrid>

您没有将

值

置于

DataTrigger

               <DataTrigger Binding="{Binding Path=IsAutoEvent}" Value="True">
                    <Setter Property="Background" Value="Red"/>
                </DataTrigger>

<DataGrid Name="EventGrid" IsReadOnly="True" AutoGenerateColumns="False" ItemsSource="{Binding Events}" SelectedItem="{Binding SelectedEvent}" CanUserAddRows="False" SelectionMode="Single" SelectionUnit="FullRow">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Start Time"  Width="Auto" Binding="{Binding StartTime, StringFormat={}{0:hh:mm:ss}}" CellStyle="{StaticResource CenterAlignedDataGridCell}"/>        
        <DataGridTextColumn Header="Description" Width="*" Binding="{Binding Description}" CellStyle="{StaticResource CenterAlignedDataGridCell}"/>
        <DataGridTextColumn Header="Comments" Width="*" Binding="{Binding Comment}"/>        
    </DataGrid.Columns>
    <DataGrid.RowStyle>
        <Style TargetType="{x:Type DataGridRow}">            
            <Style.Triggers>
                <DataTrigger Binding="{Binding Path=IsAutoEvent}" Value="True">
                    <Setter Property="Background" Value="Red"/>
                </DataTrigger>
            </Style.Triggers>

是的，完全正确。根据提交的时间，我接受了@nit的答案。但不管怎样，对你来说+1！是的，完全正确。根据提交的时间，我接受了@nit的答案。但不管怎样，对你来说+1！
