如何点击按钮弹出新窗口，输入数据后返回并刷新页面？_[Asp.Net教程] 在一些.NET论坛中有人经常会问：如何在页面中点击按钮打开新页面，输入数据，然后返回到初始页面并进行更新？要解决这个问题，应该弄清楚window.showModalDialog()的用法，本人在http://www.csdn.net/Develop/read_article.asp?id=15113已经做过介绍。下面就用例子介绍如何在ASP.NET中实现这个功能。 本例子共3个页面，其中WebForm2.aspx是过渡页面，是为了防止提交时打开新页面。 WebForm1.aspx <![CDATA[<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb"<br/>Inherits="ShowModalDialog.WebForm1" %><br/><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><br/><HTML><br/><HEAD><br/><title>WebForm1</title><br/></HEAD><br/><body MS_POSITIONING="GridLayout"><br/><form id="Form1" method="post" runat="server"><br/><asp:label id="Label1" runat="server" Font-Bold="true"><br/>从当前页面打开新窗口，并把变量传递到新窗口的例子，可以多次打开提交。<br/></asp:label><br/><asp:textbox id="TextBox1" runat="server" Width="600px">这是初始值，将被传递到新窗口。</asp:textbox><br/><asp:button id="Button1" runat="server" Text="打开窗口" Width="96px"></asp:button></form><br/></body><br/></HTML><br/>]]>WebForm1.aspx.vb <![CDATA[Public
