推荐答案

你好朋友， TD 是唯一允许在<$内的标签c $ c> TR 标签。让我们将面板控件移到 TD 中，并在面板中添加一个新表，使其结构如下：

Hello friend, TD is the only tag which is allowed within a TR tag. Let's move the panel control inside the TD and add a new table within the panel to have the same structure as follows:

<tr>	
  <td colspan="4">
    <asp:panel id="pnl1" runat="server" xmlns:asp="#unknown">
      <table>
	<tr>
	  <td>Store Name</td>
	  <td>
            <asp:dropdownlist id="ddlstore" runat="server">
              <asp:listitem text="--Select--" value="0"></asp:listitem>
            </asp:dropdownlist>
	  </td>	
	</tr>
      </table>
    </asp:panel>
  </td>
</tr>
