web版wpf开发中关于datagrid操作！

Question

刚才发了一贴关于datagrid的操作，没写清楚是web还是winform的，多谢刚才几位高手的帮助，这里重新发一次。
是web版的wpf开发，前台是xaml文件，后台是c#文件，现在要实现动态的控制datagrid中的单元格的背景色控制，
后台数据绑定是利用datacontext=model来实现刚才根据讲解写出来的代码如下：
xaml文件上：头部文件<wps:PageBase x:Class="FastRetailing.G1.WPS.Client.Biz.Monthly.View.Monthlylaborcostview"
      xmlns:wtk="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" 
              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:mc="http://schemas.openxmlformats.org/up-compatibility/2006" 
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
      mc:Ignorable="d" 
      
     xmlns:wps="clr-namespace:FastRetailing.G1.WPS.Framework.Client.Base;assembly=WPS.Framework.Client"
      xmlns:wpsv="clr-namespace:FastRetailing.G1.WPS.Framework.Client.Validation;assembly=WPS.Framework.Client"
      xmlns:l="clr-namespace:FastRetailing.G1.WPS.Client.Biz.Monthly.View"      datagrid的文件部分：<my:DataGrid ItemsSource="{Binding}" Grid.Column="3" Grid.Row="3" Height="120" HorizontalAlignment="Left" Margin="1,0,0,0" Name="dataGrid1" VerticalAlignment="Bottom" Width="1000" Grid.ColumnSpan="5" SelectionMode="Single" SelectionUnit="Cell">
            <my:DataGrid.Columns>
                <my:DataGridTextColumn Header="週間" Width="80" Binding="{Binding Path=Name}">
                    <my:DataGridTextColumn.CellStyle>
                        <Style TargetType = "my:DataGridCell">
                            <Setter Property="Background" Value="{Binding Path=Name, Converter={StaticResource ValueConVerter }}">
                            </Setter>
                        </Style >
                    </my:DataGridTextColumn.CellStyle>
                </my:DataGridTextColumn>            </my:DataGrid.Columns>
</my:DataGrid>后台c#代码如下：
public class ValueConVerter : IValueConverter
    {        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if ((int)value > 10)
            {
                return Brushes.Blue;
            }
            else
            {
                return Brushes.Green;
            }
        }        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }我现在出现的问题是标注红色的Converter部分总是提示找不到文件名，这个问题是因为我前台未到如什么文件，还是后台的这个类的创建位置有问题
谢谢各位！

我再提个建议，虽然可以做WPF浏览器应用程序，但最好不要用这种方式，因为一旦客户端程序涉及到系统操作，必须要有证书，这个讨厌的证书只能由客户设置浏览器安全项，或者在安装程序中直接安装证书，很麻烦。
所以如果是WEB程序同时具有WPF的优势，就采用SilverLight。
WPF浏览器应用程序本质上其实和WPF桌面程序一样都需要安装，反倒多了证书的麻烦，不如直接作桌面的。
