PS：这是在2010 RC中生成的代码，发现 DataGrid 的引用不是来自程序集了，而是来自 xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"

要实现的功能很简单，就是通过 DemoComparableConverter 让 DataGrid 中的单元格显示出不同的样式，我试了半天，得出几点：
1. DataGridTextColumn 只有一个依赖项属性 FontFamilyProperty ，无法以

XML code

                <sdk:DataGridTextColumn Binding="{Binding Value}"  Header="Value"                                        Foreground="{Binding Converter={StaticResource ComparableConverter}}"/>

方式进行绑定；

2. 似乎只能使用 DataGridTemplateColumn ，并对 DataTemplate 中的控件进行 Style、Foreground、Background 等依赖项属性的绑定了；

3. 如果是通过后台代码为 DataGrid 增加DataGridTemplateColumn ，那么如何在代码中为 DataTemplate 中的控件进行 Style、Foreground、Background 等依赖项属性的绑定？ 目前我是通过加载动态 DataTemplate 来实现，感觉比较麻烦：

C# code

DataGridTemplateColumn col = new DataGridTemplateColumn();col.Header = header; // header 为表头标题col.CellTemplate = (DataTemplate)System.Windows.Markup.XamlReader.Load(                        GetNumericTemplate(propertyName)); // propertyName 为要被绑定的属性名public string GetDateTemplate(string propertyName){        string template = @"<DataTemplate    xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'    xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>            <TextBlock Text='{Binding @PropertyName}'                        Style='{Binding Converter={StaticResource ComparableConverter}}'                        VerticalAlignment='Center' /></DataTemplate>";       return template.Replace("@PropertyName", propertyName);}

加载动态 DataTemplate 还可以直接使用 Resources ，但是我不知道该如何动态的指定 propertyName

C# code

col.CellTemplate =(DataTemplate) this.Resources["ADataTemplate"];

不知各位有没有更方便的方法？或者网络上早已有正解~~~~

如果是Converter可 Binding="{Binding Sex, Converter={StaticResource sexConvert},Mode=TwoWay}" 参考:http://blog.csdn.net/xingjunli/archive/2010/02/24/5322377.aspx
