button | data | refresh | page in some. NET Forum Some people often ask: How to click the button in the page to open a new page, enter data, and then return to the original page and update? To solve this problem, we should make clear the use of window.showModalDialog (), I have been introduced in http://www.csdn.net/Develop/read_article.asp?id=15113. Here is an example of how to implement this functionality in ASP.net.
This example is a total of 3 pages, where webform2.aspx is a transition page to prevent the new page from being opened when it is submitted.
WebForm1.aspx
<%@ Page language= "vb" autoeventwireup= "false" codebehind= "WebForm1.aspx.vb"
inherits= "Showmodaldialog.webform1"%>
<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 transitional//en" >
<HTML>
<HEAD>
<title>WebForm1</title>
<meta content= "Microsoft Visual Studio. NET 7.0" name= "Generator" >
<meta content= "Visual Basic 7.0" name= "Code_language" >
<meta content= "JavaScript" name= "vs_defaultClientScript" >
<meta content= "http://schemas.microsoft.com/intellisense/ie5" name= "Vs_targetschema" >
</HEAD>
<body ms_positioning= "GridLayout" >
<div align= "center" >
<form id= "Form1" method= "POST" runat= "Server" >
<asp:label id= "Label1" runat= "Server" font-bold= "true" >
The example of opening a new window from the current page and passing the variable to the new window allows you to open the submission multiple times.
</asp:label><br>
<br>
<asp:textbox id= "TextBox1" runat= "Server" width= "600px" > This is the initial value and will be passed to the new window. </asp:textbox><br>
<br>
<asp:button id= "Button1" runat= "Server" text= "open Window" width= "96px" ></asp:button></form>
</div>
</body>
</HTML>
