FormView在什么情况下自动生成模板项?

刚才在鼓捣GridView与FormView，记得前一段时间在做时，点击gridview中的一项会在formview中显示详细的数据，而在 formview中只有编写了ItemTemplate等模板才会显示，我清楚的记得上次我并没有手工去编写itemTemplate模板，在查看、编辑、删除时的模板都是自动生成的，这次始终不成功，我又不愿意去手工写一些itemtemplate，如果有20个字段，我都手写就太累了。。。

偷懒之余，就用FormView的向导功能来做，不料，那些模板又自动生成了。怪。

 

也自动生成了如下模板:

<EditItemTemplate>
                CustomerID:
                <asp:Label ID="CustomerIDLabel1" runat="server" Text='<%# Eval("CustomerID") %>'>
                </asp:Label><br />
                CompanyName:
                <asp:TextBox ID="CompanyNameTextBox" runat="server" Text='<%# Bind("CompanyName") %>'>
                </asp:TextBox><br />
                ContactName:
                <asp:TextBox ID="ContactNameTextBox" runat="server" Text='<%# Bind("ContactName") %>'>
                </asp:TextBox><br />
                ContactTitle:
                <asp:TextBox ID="ContactTitleTextBox" runat="server" Text='<%# Bind("ContactTitle") %>'>
                </asp:TextBox><br />
                Address:
                <asp:TextBox ID="AddressTextBox" runat="server" Text='<%# Bind("Address") %>'>
                </asp:TextBox><br />
                City:
                <asp:TextBox ID="CityTextBox" runat="server" Text='<%# Bind("City") %>'>
                </asp:TextBox><br />
                Region:
                <asp:TextBox ID="RegionTextBox" runat="server" Text='<%# Bind("Region") %>'>
                </asp:TextBox><br />
                PostalCode:
                <asp:TextBox ID="PostalCodeTextBox" runat="server" Text='<%# Bind("PostalCode") %>'>
                </asp:TextBox><br />
                Country:
                <asp:TextBox ID="CountryTextBox" runat="server" Text='<%# Bind("Country") %>'>
                </asp:TextBox><br />
                Phone:
                <asp:TextBox ID="PhoneTextBox" runat="server" Text='<%# Bind("Phone") %>'>
                </asp:TextBox><br />
                Fax:
                <asp:TextBox ID="FaxTextBox" runat="server" Text='<%# Bind("Fax") %>'>
                </asp:TextBox><br />
                <asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True" CommandName="Update"
                    Text="更新">
                </asp:LinkButton>
                <asp:LinkButton ID="UpdateCancelButton" runat="server" CausesValidation="False" CommandName="Cancel"
                    Text="取消">
                </asp:LinkButton>
            </EditItemTemplate>

下面是该FormView的DataSource:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
            InsertCommand="insert into customers (CustomerID,CompanyName,ContactName,ContactTitle,Address,City) values (@customerid,@companyname,@contactName,@contactTitle,@address,@city)"
            SelectCommand="select * from customers where customerid=@customerid" UpdateCommand="update customers set companyname=@companyname,contactName=@contactName,contactTitle=@contactTitle where customerid=@customerid">
            <UpdateParameters>
                <asp:Parameter Name="companyname" />
                <asp:Parameter Name="contactName" />
                <asp:Parameter Name="contactTitle" />
                <asp:Parameter Name="customerid" />
            </UpdateParameters>
            <SelectParameters>
                <asp:Parameter Direction="input" Name="customerid" Type="string" />
            </SelectParameters>
            <InsertParameters>
                <asp:Parameter Name="customerid" />
                <asp:Parameter Name="companyname" />
                <asp:Parameter Name="contactName" />
                <asp:Parameter Name="contactTitle" />
                <asp:Parameter Name="address" />
                <asp:Parameter Name="city" />
            </InsertParameters>
        </asp:SqlDataSource>

直到现在还是晕晕的，不知道怎么样才能使之自动生成模板，难道只有在向导的情况下才会生成？
