好吧我很难过,我有一个好的10个其他页面都使用相同的布局等所有工作正常,但我创建了一个新的页面,无法让它工作。
我注意到导致错误的原因,但我不知道为什么或如何解决它。 看看下面的代码,
它是一个带有runat=server , Ext.Net Resource Manager,Viewport,Tab Panel和2 Panels的表单,后面没有代码。
当我加载这个时,我得到了可怕的this.el is null在Firefox中this.el is null并且Uncaught TypeError: Cannot set property 'setSize' of null在Chrome中Uncaught TypeError: Cannot set property 'setSize' of null 。 但是,我删除了表单标签,一切正常。 现在您可能会说删除表单标记,但我不能在以后添加需要此标记的asp.net控件。
标记:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="PriceSetting.aspx.cs" Inherits="V2_RenewalsProcess_PriceSetting" %> <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %> <DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Ovott V2</title> </head> <body> <form id="pricesetting" runat="server"> <ext:ResourceManager ID="ResourceManager1" runat="server" /> <ext:Viewport ID="Viewport1" runat="server" Layout="border"> <Items> <ext:TabPanel ID="TabPanel1" runat="server" Region="Center"> <Items> <ext:Panel ID="Panel5" runat="server" Title="To Be Submitted" Border="false"> </ext:Panel> <ext:Panel ID="Panel6" runat="server" Title="Awaiting Approval"> </ext:Panel> </Items> </ext:TabPanel> </Items> </ext:Viewport> </form> </body> </html>Ok I'm stumped, I have a good 10 other pages all using the same layout etc all working fine, but I created a new page and cannot get it to work.
I have noticed what is causing the error but I don't know why or how to fix it. Have a look at the code below,
Its a form with runat=server, Ext.Net Resource Manager, Viewport, Tab Panel and 2 Panels, no code behind.
When I load this i get the dreaded this.el is null in Firefox and Uncaught TypeError: Cannot set property 'setSize' of null in Chrome. But alas I remove the form tag and everything works as it should. Now you might say well just remove the form tag, but I cant will add asp.net controls later that needs this tag.

好吧,最后在我的同事的帮助下,我们解决了这一切,这一切都归结为一个角色......一个“!” 你可能会问在哪里?
原始代码
<DOCTYPE html PUBLIC "...固定代码
<!DOCTYPE html PUBLIC "...现在它正在运作
OK finally with the help of my colleague we solved this and it all came down to one character... a "!" and you might ask where?
