推荐答案

我假设您像这样加载数据列表

i asuuming that you load your data list like this

 <asp:datalist id="DataList1" runat="server" onselectedindexchanged="DataList1_SelectedIndexChanged">
  <itemtemplate>
	<table class="style1">
	   <tr>
	    <td>
	        <asp:label id="Label1" runat="server" text="<%#Eval("Id") %>"></asp:label>
   </td>
 <td>
<asp:button id="Button1" runat="server" text="Button" onclick="Button1_Click" />
	   </td>
	  </tr>
	</table>
 </itemtemplate>
</asp:datalist>

因此，您单击按钮的代码与此相同，您可以单击数据列表中每一行的按钮，并从文本框中的每一行获取ID

and so you button click will be same this code you can click button in each row in data list and get Id from each row in a textbox

protected void Button1_Click(object sender, EventArgs e)
		{
			Button BuyNowButton = (Button)sender;
                DataListItem item = (DataListItem)BuyNowButton.NamingContainer;
                Label NameLabel = (Label)item.FindControl("label1");
	        TextBox1.Text = NameLabel.Text;
		}
