You can only have one <head runat="server"> control on a page
运行时候提示
You can only have one <head runat="server"> control on a page
前台：

Collapsed="false"
TextLabelID="show"
ExpandedText="隐藏申请单"
CollapsedText="显示申请单"
>

后台：

 GetITBillDetail fuc = new GetITBillDetail();
        string controlPath = fuc.getControlName(HidBillType.Value);
        Control c = Page.LoadControl(controlPath);
        p2.Controls.Add(c);  //这里报错

[解决办法]
页面有多个 <head runat="server"> 定义，你在页面里搜下是不是多个head，去掉多余的保留一个 <head runat="server"> 就行了
[解决办法]
那就还有多个<head>

You can only have one lt;head runat=quot;
