目的：加入用户自定义控件
错误提示：System.Web.HttpException: 类型'TextBox'的控件'ctl02_TextBox2'必须放在具有 runat=server 的窗体标记内。
没有ctl02_TextBox2这个控件啊？
WebUserControl.ascx 代码

<asp:Button ID= "Button1 " runat= "server " Text= "Button " />
<asp:TextBox ID= "TextBox1 " Text= "tb1 " runat= "server "> </asp:TextBox>
<asp:Button ID= "Button2 " runat= "server " Text= "Button " />
