Как управлять кнопкой с панели

Question

Я новичок в ASP.NET. Я взял Panel. Внутри Panel я взял столик. Внутри стола находятся TextBox, RadioButton и элементы управления Button.

Я написал код в button_click события. Но ничего не происходит. button_click Событие не стреляет. Что теперь делать?

У меня есть и другие вещи в панели. Но событие click не работает.

код ниже:

<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>

Answer 1

Если кнопка находится в DataList или GridView, например, установить свойство CommandName. Объект databound (datalist, gridview) имеет ItemCommand-event. Поместите код в это событие. Pseudo code:

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