wpf DataGrid行背景色绑定

1、创建BgROW类

    public class BgROW : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {

            if (value.ToString()=="true")
            {
                return new SolidColorBrush(Color.FromRgb(46, 170, 231));
            }
            else
                return new SolidColorBrush(Color.FromRgb(229, 73, 54));
        }
        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

2、在xaml中引入BgRow，然后在<ResourceDictionary>中加入<Bg:BgROW x:Key="bgRow"/>，最后添加<Setter Property="Background" Value="{Binding IsErr, Converter={StaticResource bgRow}}"/>对行背景色进行绑定

        <DataGrid x:Name="dgProduct" Grid.Row="1" Margin="50,30,50,30" Background="#FFFFFF" HorizontalGridLinesBrush="Gray" VerticalGridLinesBrush="Transparent" HeadersVisibility="Column" CanUserAddRows="False" AutoGenerateColumns="False" IsReadOnly="True">
                <DataGrid.Resources>
                    <ResourceDictionary>
                        <Bg:BgROW x:Key="bgRow"/>
                        <Style x:Key="dgStyle" TargetType="TextBlock">
                            <Setter Property="FontSize" Value="35"/>
                            <Setter Property="TextWrapping" Value="Wrap"/>
                            <Setter Property="HorizontalAlignment" Value="Center"/>
                            <Setter Property="VerticalAlignment" Value="Center"/>
                        </Style>
                    </ResourceDictionary>
                </DataGrid.Resources>
                <DataGrid.Columns>
                    <DataGridTextColumn Header="商品编码" Width="1.5*" ElementStyle="{StaticResource dgStyle}" Binding="{Binding Code}"/>
                    <DataGridTextColumn Header="商品名称" Width="1.5*" ElementStyle="{StaticResource dgStyle}" Binding="{Binding Name}"/>
                    <DataGridTextColumn Header="款号" Width="1.5*" ElementStyle="{StaticResource dgStyle}" Binding="{Binding Style}"/>
                    <DataGridTextColumn Header="颜色" Width="*" ElementStyle="{StaticResource dgStyle}" Binding="{Binding Color}"/>
                    <DataGridTextColumn Header="尺码" Width="*" ElementStyle="{StaticResource dgStyle}" Binding="{Binding Size}"/>
                    <DataGridTextColumn Header="数量" Width="*" ElementStyle="{StaticResource dgStyle}" Binding="{Binding Count}"/>
                    <DataGridTextColumn Header="状态" Binding="{Binding Statu}" Visibility="Hidden"/>
                </DataGrid.Columns>
                <DataGrid.ColumnHeaderStyle>
                    <Style TargetType="{x:Type DataGridColumnHeader}">
                        <Setter Property="HorizontalContentAlignment" Value="Center"/>
                        <Setter Property="Background" Value="#D7D7D7"/>
                        <Setter Property="Height" Value="70"/>
                        <Setter Property="FontSize" Value="45"/>
                        <Setter Property="BorderBrush" Value="Gray"/>
                        <Setter Property="BorderThickness" Value="1"/>
                        <Setter Property="Foreground" Value="#FF363434"/>
                    </Style>
                </DataGrid.ColumnHeaderStyle>

                <DataGrid.RowStyle>
                    <Style TargetType="DataGridRow">
                        <!--单元格不可选中-->
                        <Setter Property="IsHitTestVisible" Value="False"/>
                        <Setter Property="Height" Value="90"/>
                        <Setter Property="Background" Value="{Binding IsErr, Converter={StaticResource bgRow}}"/>
                    </Style>
                </DataGrid.RowStyle>
            </DataGrid>
