这段代码看不懂。。

请教下，这段代码是设置城市的，是个下拉的选择，我想找出设置这些城市的文件，并把城市换掉，要怎么做？？
怎样找？这个是在数据库中设置的，还是代码中设置的？？请高手指点。<tr>
                        <td width="80" align="right" bgcolor="#FAFAFA">
                            城    市：</td>
                        <td bgcolor="#FFFFFF" align="left">
                            <asp:DropDownList ID="ddCity1" runat="server">                            </asp:DropDownList>
                            <asp:DropDownList ID="ddCity2" runat="server" Width="100px">                            </asp:DropDownList>
                            <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="ddCity1"
                                ErrorMessage="区域不能为空," SetFocusOnError="True" Display="Dynamic"></asp:RequiredFieldValidator>
                            <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ControlToValidate="ddCity2"
                                ErrorMessage="地段不能为空!" SetFocusOnError="True" Display="Dynamic"></asp:RequiredFieldValidator></td>
                    </tr>

这两个DropDownList 的数据肯定是动态加载上去的，也就是说可能是从数据库或者写代码加上去的，找找这个页面的代码文件，看看有没有加载数据的代码，替换掉就OK。
这个是上面那段代码所在文件的全部代码：

估计是你连数据库读数据的时候没有读到数据,最好跟一下这个方法看看
从数据库读取数据绑定到下拉框的，All_ModelInfoList_byType("city")去这个方法看看
