将“是/否”DropDownList添加到简单的EditItemTemplate

Question

我有一个非常简单的表要更新。有5个char（1）列，每个列存储“Y”或“N”。这些列名为Priority1 .. Priority5。我创建了一个简单的更新表单，但当然默认的EditItemTemplate允许用户键入这些列的值。我想将此选项的编辑选项更改为只能为5列选择“Y”或“N”的下拉列表。这在经典ASP中很简单，但我很挣扎。有人可以解释我是怎么做到的吗？

这不是一个重复的问题。我不想将下拉选项绑定到数据库字段。我想在下拉列表中手动编码它可以是Y或N，并让代码抓住文本数据库字段中的任何内容。

我的表格如下。

<form id="form1" runat="server">
<div>
    <asp:FormView ID="FormView1" runat="server" DataKeyNames="NotificationsMatrixID" DataSourceID="SqlDataSource1">
        <EditItemTemplate>

            <asp:Label ID="NotificationsMatrixIDLabel1" runat="server" Text='<%# Eval("NotificationsMatrixID") %>' />
            <br />
            CustID:
            <asp:TextBox ID="CustIDTextBox" runat="server" Text='<%# Bind("CustID") %>' />
