Question

我是ASP.NET新手。我采取了Panel。在Panel里面，我已经拿了一张桌子。表格内有TextBox，RadioButton和Button控件。

我在button_click事件中编写了一些代码。但没有任何反应。 button_click事件未触发。现在该怎么办？

我还有一些其他的东西在面板中。但没有点击事件正在发挥作用。

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">

                </td>
            </tr>
            </table>
        </ItemTemplate>
    </asp:DataList>

例如，如果按钮位于datalist或gridview中，请设置CommandName属性。数据绑定对象（datalist，gridview）具有ItemCommand事件。将代码放在此事件中。伪代码：

if (e.CommandName.equals(your_command_name)){ label1.text = e.CommandArgument };
