在ASP.NET Webform上实现多个默认按钮的最佳方法

<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button1_Click" CausesValidation="True" />
</asp:Panel>
<asp:Panel ID="Panel2" runat="server" DefaultButton="Button2">
    <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
    <asp:Button ID="Button2" runat="server" Text="Button2" OnClick="Button2_Click" CausesValidation="True" />
</asp:Panel>

protected void Button1_Click(object sender, EventArgs e)
{
    // 处理 Button1 的点击事件
}

protected void Button2_Click(object sender, EventArgs e)
{
    // 处理 Button2 的点击事件
}
