我有一个复杂的类型如下

 public class EmployeessList
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LatName { get; set; }

}

我将上述复杂类型的列表绑定到数据网格，所以

    <sdk:DataGridTemplateColumn Header="Value" Width="150*" >
                                                                    <sdk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<StackPanel VerticalAlignment="Center">
<TextBox x:Name="{Binding Id}"  Text="{Binding FirstName,Mode=TwoWay}"   />
</StackPanel>
</DataTemplate>
                                                                    </sdk:DataGridTemplateColumn.CellTemplate>

如上所述，我想将多个属性绑定到文本框的多个属性，例如

当我运行此代码时，它给出了错误 xaml 解析异常，如下所示。

你的问题出在这部分：

x:Name="{Binding Id}"

您不能绑定 x:Name 属性（来源here和here）。你能解释一下你想通过绑定那个属性来实现什么吗？也许它可以通过其他方式完成。
