推荐答案

根据您的要求，不清楚您要尝试的是什么你被困在哪里
对于Web applicaton，打印代码必须在客户端.

您可以在代码后面编写与打印相关的代码，然后将其注入到页面中:

Based on what you ask, it''s not too clear on what specifically you are trying and where are you stuck.
For Web applicaton, print code has to be on client side.

Either you can write your print related code in code behind and then inject it into the page:

OR using JavaScript directly on the page itself, like:

function CallPrint()
{
  var printContent = document.getElementById('<%= pnlToPrint.ClientID %>');
  var printWindow = window.open("", "Print Panel", ‘left=50000,top=50000,width=0,height=0′);
  printWindow.document.write(prtContent.innerHTML);
  printWindow.document.close();
  printWindow.focus();
  printWindow.print();
  printWindow.close();
}

<asp: Panel runat="server" id="pnlToPrint" >
  <table>
    <tr>
      <td>
         Your data
      </td>
    </tr>
  </table>
</asp: Panel>

<input type="button" value="Print"  onclick="CallPrint();" />
