您当前的位置: 各位，为什么在我启动页面时，被多次提交，也就是page_load被走了多次。
asp.net代码如下（page_load走了4次）：
- HTML code
<%@ Page Language="vb" AutoEventWireup="true" CodeFile="Login.aspx.vb" Inherits="Login" %>
<!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 id="Head1" runat="server">
<title>login</title>
</head>
<body style="background-color: #fefefe">
<form id="form1" runat="server">
<div style="top: 0px;">
<table cellpadding="0" cellspacing="0" id="main" runat="server" style="width: 100%;
height: 590px; text-align: center; background-color: #fefefe; top: 0px">
<tr>
<td style="height: 300px; vertical-align: bottom;">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<table cellpadding="0" cellspacing="0" id="main_up" runat="server" style="background-color: #fefefe;
width: 100%; text-align: center">
<!-- service logo -->
<tr>
<td style="background-image: url(image/backimage.gif); background-repeat:repeat-x; width: 20%; background-attachment: scroll; height: 100%;">
</td>
<td colspan="3" align="left" style="background-image: url(~/image/backimage.gif); background-repeat:repeat-x; width: 25%;">
<asp:Image ID="ImageLK" runat="server" ImageUrl="~/image/LK-logo.gif" />
</td>
<td style="background-image: url(image/backimage.gif); background-repeat:repeat-x; width: 20%; background-attachment: scroll;">
</td>
</tr>
</table>
</ContentTemplate>
</asp:UpdatePanel>
</td>
</tr>
</table>
</div>
<div style="text-align : center;">
<asp:Label ID="Label1" runat="server" Text="Copyright© aaa, Inc." Font-Names="Verdana" Font-Size="XX-Small"></asp:Label></div>
</form>
</body>
</html>
如果去掉
- HTML code
<td colspan="3" align="left" style="background-image: url(~/image/backimage.gif); background-repeat:repeat-x; width: 25%;">
<asp:Image ID="ImageLK" runat="server" ImageUrl="~/image/LK-logo.gif" />
</td>
那么page_load就被走了2次。
