标题听起来很拗口，所以让我试着解释一下。我非常擅长开发 Web 表单，这是我使用框架和 MVC 的第二次尝试（不要问第一个）。从这样的表开始：
Title: Milestones
Id int - Auto, PK
Project_Id int - FK, 许多里程碑到一个项目，暂时提供静态
Number int
Name varchar(50)
Status_Id int - FK 一个状态到一个里程碑
PlannedDate date
LatestEstimate date
MilestoneType_ID int - FK 一种类型到一个里程碑
这些都位于 SQL 服务器上，由实体拉入，然后由 ObjectDataSource 拉入，如下所示：
<asp:ObjectDataSource runat="server" ID="MilestonesObjectSource" SelectMethod="GetByProject"
DeleteMethod="DeleteMilestone" TypeName="TCProjectManagement.Models.MilestonesAddition">
<SelectParameters>
<asp:Parameter DefaultValue="6" Name="ProjectID" Type="Int32" />
</SelectParameters>
<DeleteParameters>
<asp:Parameter Type="Int32" Name="Id" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Type="Int32" Name="Id" />
<asp:Parameter Type="Int32" Name="Number" />
<asp:Parameter Type="String" Name="Name" />
<asp:Parameter Type="Int32" Name="Status_Id" />
<asp:Parameter Type="DateTime" Name="PlannedDate" />
<asp:Parameter Type="DateTime" Name="LatestEstimate" />
<asp:Parameter Type="Int32" Name="MilestoneType_ID" />
</UpdateParameters>
</asp:ObjectDataSource>
到目前为止，一切都很好。数据拉取似乎没问题。我还有几个专门处理外键的对象源，所以我会跳过那些，因为它们似乎在工作。
我遇到的问题是试图将许多似乎不太协调的例子拼接在一起。我的目标，没有特别的顺序：
1) Pin Editing：点击按钮进行编辑，再次点击确认。与其让某人推断双击以进行更改，不如这样做。到目前为止，这种方法是有效的。
2) 外键下拉菜单：当不在编辑模式时，应显示外键的“名称”字段。在编辑时，它应该是一个下拉选项（只有三个）。尽管我做了什么，这仍然是空白。
3) 删除：按一个按钮删除一行。我把按钮放在那里，但它是用于编辑的 JS 的副本。我需要用什么来删除它？
4）日期：这根本不起作用。奇怪的部分之一是，从 SQL 服务器的 Date 类型，它在实体中更改为 DateTime 并始终保持这种状态。但是，我无法获得所需的 ext:DateField 控制来与提供的数据合作，因为它显示时间并且在编辑时完全空白。我知道我在这里做错了。
5）保存更改：不太确定我是否设置正确（或根本不正确）。
Javascript的规定：
<script type="text/javascript">
var pinEditors = function (btn, pressed) {
var columnConfig = btn.column,
column = columnConfig.column;
if (pressed) {
column.pinOverComponent();
column.showComponent(columnConfig.record, true);
} else {
column.unpinOverComponent();
column.hideComponent(true);
}
};
var pinDeleters = function (btn, pressed) { };
</script>
