相关疑难解决方法(0)

我有一个web方法,将从jquery ajax调用:

[WebMethod]
public string TestMethod(string param1, string param2)
{
    StringBuilder b = new StringBuilder();
    HtmlTextWriter h = new HtmlTextWriter(new StringWriter(b));
    this.LoadControl("~/Pages/Controls/Listing.ascx").RenderControl(h);
    string controlAsString = b.ToString();
    return controlAsString;
}

(这是一种非静态的方法,我们能够击中它.这不是问题)

执行loadControl()方法时,我收到一条错误消息:只能在Render期间调用RegisterForEventValidation.

我已经为当前的aspx,禁用的viewstate包含了EnableEventValidation ="false".但我仍然得到同样的错误.有什么想法吗？

当添加在服务器上运行的表单时,将有两个表单与runat服务器,并发生另一个错误.有人可以给我一个想法.提前谢谢.

错误的细节如下.

必须将带有'TextBox'类型的控件'ctl00_TextBox1'放在带有runat = server的表单标记内.描述:执行当前Web请求期间发生未处理的异常.请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息.

异常详细信息:System.Web.HttpException:类型为"TextBox"的控件"ctl00_TextBox1"必须放在带有runat = server的表单标记内.

来源错误:

在执行当前Web请求期间生成了未处理的异常.可以使用下面的异常堆栈跟踪来识别有关异常的起源和位置的信息.
