更新模型后，这些值不会反映在视图上

我使用 Visual Web Developer 2010 和 ASP .NET 与 MVC2 创建了一个简单的客户管理模块，其中视图将允许输入名字、姓氏、地址等，提交后，将分配一个新的“ID” CustomerModel 实例的 CustomerID 属性。

用于创建客户的控制器方法（CustomerController）如下：

<HttpPost()> _
Public Function CreateCustomer(ByVal model As CustomerModel) As ActionResult
    model = Me.customerServiceClientValue.CreateCustomer(model)
    Return (View(model))
End Function

我可以看到控件到达了CreateCustomer（）方法内部，并且它调用客户服务来创建客户。该服务还会向客户返回一个新 ID。正如在该方法中一样，从服务调用返回的客户实例被分配回传入的“模型”变量。该模型实例被传递到返回语句中的“视图”。然而，当刷新视图时，我没有看到客户 ID 字段的值。

我的客户 ID 字段有以下标记：

<div class="editor-label">
    <%: Html.LabelFor(Function(model) model.CustomerID)%>
</div>
<div class="editor-field">
    <%: Html.TextBoxFor(Function(model) model.CustomerID)%>
    <%: Html.ValidationMessageFor(Function(model) model.CustomerID)%>
</div>

我做错了什么？尽管模型包含新的客户 ID，为什么我在字段中没有获取客户 ID？感谢您的所有帮助。

谢谢和问候，

原文

I used Visual Web Developer 2010 and ASP .NET with MVC2 to create a simple Customer Management module, where the view will allow entering first name, last name, address, etc., and upon submitting, a new "ID" will be assigned to the CustomerID property of the CustomerModel instance.

The Controller method (CustomerController) for creating customer is as below:

<HttpPost()> _
Public Function CreateCustomer(ByVal model As CustomerModel) As ActionResult
    model = Me.customerServiceClientValue.CreateCustomer(model)
    Return (View(model))
End Function

I can see that the control reaches inside the CreateCustomer () method, and it calls the Customer Service to create the customer. The service returns a customer with a new ID as well. As in the method, the customer instance returned from the service call is assigned back to the "model" variable that came in. That model instance is passed to the "View" in the return statement. Yet, when the view is refreshed, I do not see a value for the customer ID field.

I have the following mark-up for the customer ID field:

<div class="editor-label">
    <%: Html.LabelFor(Function(model) model.CustomerID)%>
</div>
<div class="editor-field">
    <%: Html.TextBoxFor(Function(model) model.CustomerID)%>
    <%: Html.ValidationMessageFor(Function(model) model.CustomerID)%>
</div>

What am I doing wrong? Why am I not getting the Customer ID in the field, although the model contains the new Customer ID? Appreciate all your helps.

Thanks and regards,
