为什么提示这样一个错误：类型“dropdownlist”控件“search_dep_id”必须放在具有“runat=server”的窗体标记内
<asp:dropdownlist   id=”search_dep_id”   runat=”server”   datatextfield=”dep_name”   datavaluefield=”dep_id”> </dropdownlist>

我已经放进去了啊



------解决方案--------------------
<form id= "form1 " runat= "server ">

//放在这里面

</form>

------解决方案--------------------
不仅要放到form里面,而且form必须 runat= "server "

<form id= "Form1 " method= "post " runat= "server ">
<asp:dropdownlist id=”search_dep_id” runat=”server” datatextfield=”dep_name” datavaluefield=”dep_id”> </dropdownlist>
</form>
