如何从面板控制按钮

我是ASP.NET的新手。我选了一个Panel。在Panel里面，我选了一张桌子。表内有TextBox、RadioButton和Button控件。

我在button_click事件中写了一些代码。但是什么也没发生。button_click事件未触发。现在该怎么办?

我也有一些其他的东西在面板。但是没有点击事件。

代码如下:

<asp:Panel ID="Pnlproducts" runat="server" ScrollBars="Auto" Height="500px" BorderColor="Black" BorderStyle="Inset" BorderWidth="1px">
    <asp:DataList ID="DLProducts" runat="server" RepeatColumns="3" Width="600px" OnSelectedIndexChanged="DLProducts_SelectedIndexChanged">
        <ItemTemplate >
            <table align="left" class="auto-style6" style="border-color:#9900FF;border-left:1px;border-right:1px;border-top:1px;">
            <tr>
                <td style="border-color: #000000; border-width: 1px; border-bottom-style: ridge" class="auto-style8">
                    <asp:Label ID="lblProductName" runat="server" Text="<%# Bind('ProductName') %>" Font-Bold="True"></asp:Label>
                </td>
            </tr>
            <tr>
                <td class="auto-style9">
                    <asp:Image ID="Image2" runat="server" Height="160px" ImageUrl="<%# Bind('ProductImage') %>" Width="173px" Style="border:ridge 1px black" />
                </td>
            </tr>
            <tr>
                <td class="auto-style9"><strong>Price:</strong><asp:Label ID="lblPrice" runat="server" Text="<%# Bind('ProductPrice') %>" Font-Bold="True" ForeColor="Red"></asp:Label>
                </td>
            </tr>
            <tr>
                <td class="auto-style9">

            </tr>
            </table>
