在 ASP.NET 中使用多个 runat=server form

ASP.NET 在同一个页面不支持多个 runat=server forms,要解决这个问题,可以把每个 form 放在一个单独的 panel 控件中,这样用户就可以简单地通过单选按钮在不同 panel 间切换。
代码如下:
2FormExample.aspx

<%@ Page language="c#" Codebehind="2FormExample.cs" AutoEventWireup="false" Inherits="_3leaf_app.C2FormExample" %>
<html><head>
<meta name=vs_targetSchema content="HTML 4.0">
<meta name="GENERATOR" Content="Microsoft Visual Studio 7.0">
<meta name="CODE_LANGUAGE" Content="C#"></head>
<body>

<form method="post" runat="server" ID=Form1>
<p>Lookup by
<asp:RadioButton id=RadioButton1 runat="server" Text="First Name" AutoPostBack="True" groupname=g1 checked=True></asp:RadioButton>
<asp:RadioButton id=RadioButton2 runat="server" Text="Last Name" AutoPostBack="True" groupname=g1></asp:RadioButton></p>
<p></p>
<p>
<asp:Panel id=Panel1 runat="server" visible=True>
First Name :
<asp:TextBox id=TextBox1 runat="server"></asp:TextBox>
<asp:RequiredFieldValidator id=RequiredFieldValidator1 runat="server" ErrorMessage="*" ControlToValidate="TextBox1"></asp:RequiredFieldValidator>
<asp:Button id=Button1 runat="server" Text="Submit"></asp:Button>
</asp:Panel>
<asp:Panel id=Panel2 runat="server" visible=False>
Last Name :
<asp:TextBox id=TextBox2 runat="server"></asp:TextBox>
<asp:RequiredFieldValidator id=RequiredFieldValidator2 runat="server" ErrorMessage="*" ControlToValidate="TextBox2"></asp:RequiredFieldValidator>
<asp:Button id=Button2 runat="server" Text="Submit"></asp:Button>
</asp:Panel>
<p></p>
<p>
<asp:label id=Label1 runat="server"></asp:label>
</p>
</form>

</body></html>

//
