将文本块更改为文本框会丢失数据绑定 -

这是一个wpf / c#app - 我有一个网格,我使用文本框,数据绑定很好。我后来使用文本块构建了另一个网格。两者都运作良好。但当我将第二个网格中的文本块更改为文本框时,除了一个之外的所有文本块都停止显示数据。

我复制了c#LINQ代码和XAML代码,它们为绑定提供数据,重新编译,保存到NotePad ++,并关闭VS(8)。重新打开项目后,我重新插入了代码,但我仍然没有数据。

任何有用的想法都会受到高度赞赏。

这是c#代码

var vendDetail = from v in dbC.Vendors
                  where v.VendorID == vendorid
                   select new
                   {
                      v.Address1,
                      v.Address2,
                      CSZ = v.City + ", " + v.State + " " + v.Zip,
                      v.Phone,
                      v.Fax,
                      v.Contact,
                      v.Terms,
                      v.eMail
                    };

                grVendorData.DataContext = vendDetail;

和XAML代码:

                                                                                 

                                    <TextBox x:Name="txtVendorAddr1"
