页面仅显示一个服务器端表单标签错误，尽管我只有一个表单标签，但我也没有使用任何母版页。请帮助我这可能是什么问题。 我已经发布了页面的完整代码，请查看这个我没有在代码中的任何地方使用表单标签。
一件事是它在本地工作完全正常，但当推送到服务器时，我们收到此错误
我正在使用 XMLWorkerHelper 生成 PDF 是因为这个错误吗？
更新页面加载代码
protected void Page_Load(object sender, EventArgs e)
{
pageName = Path.GetFileName(Request.Path);
uid = Session["UserID"] != null ? Convert.ToString(Session["UserID"].ToString().Trim()) : "";
if (IsPostBack == false)

if ((Session["RoleCode"].ToString() == "11") || (Session["RoleCode"].ToString() == "2") || (Session["RoleCode"].ToString() == "5") || (Session["RoleCode"].ToString() == "8") || (Session["RoleCode"].ToString() == "4"))

uploading();
gridstoragebind();
export_click(this, null);
}
else

Session.Clear();
Response.Redirect("~/Login.aspx");

【问题讨论】：
-
@SelimYıldız 正如我所说我没有此页面的任何母版页
-
我们在这里遗漏了一些东西。在“查看源代码”中搜索“表单”，看看是否可以找到第二个？
-
@IrishChieftain 即使在“查看源代码”页面中也只显示一个表单标签
-
你能展示 Uploading() 方法的代码吗？
