在ASP.NET1.0中，我就为了设置表单中的默认按钮而一筹莫展。幸好ASP.NET2.0把这个功能补上了，现在可以非常方便的设置表单中的默认按钮了。
<%@ page language="C#" %>
<script runat="server">
void Button1_Click(object sender, System.EventArgs e)
{
this.LB_Message.Text = "You clicked button1";
}
</script>
<html>
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form runat="server" defaultbutton="Button1">
<asp:textbox id="Textbox1" runat="server"></asp:textbox>
<asp:button id="Button1" runat="server" text="Button" onclick="Button1_Click" />
<asp:label id="LB_Message" runat="server"></asp:label>
</form>
</body>
</html>
<%@ page language="C#" %>
<script runat="server">
void Button1_Click(object sender, System.EventArgs e)
{
this.LB_Message.Text = "You clicked button1";
}
</script>
<html>
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form runat="server" defaultbutton="Button1">
<asp:textbox id="Textbox1" runat="server"></asp:textbox>
<asp:button id="Button1" runat="server" text="Button" onclick="Button1_Click" />
<asp:label id="LB_Message" runat="server"></asp:label>
</form>
</body>
</html>
