用IE显示页面左下角显示“网页有错误",用toolbar调试显示 theForm.submit();这一行有无效的语法                                                                                    Text="Detail">

function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}

触发这个事件的控件为：

 <asp:LinkButton ID="btnDetail" runat="server" CommandName="Detail" CommandArgument='<%# DataBinder.Eval((System.Data.DataRowView)Container.DataItem,"column_id") %>'
请问这个错误怎么该啊，在线等，谢谢
