它可以使用JavaScript來完成。 說你的HTML/ASPX代碼都這樣說:
<span>Main heading</span>
<asp:Label ID="lbl1" runat="server" Text="Contents"></asp:Label>
<asp:Label Text="Contractor Name" ID="lblCont" runat="server"></asp:Label>
<div id="forPrintPreview">
<asp:Label Text="Company Name" runat="server"></asp:Label>
<asp:GridView runat="server">
//GridView Content goes here
</asp:GridView
</div>
<input type="button" onclick="PrintPreview();" value="Print Preview" />
這裏對「打印預覽」按鈕的點擊,我們將打開一個窗口,用於打印數據。 注意'forPrintPreview'是div的id。 的打印預覽功能變爲這樣:
function PrintPreview() {
var Contractor= $('span[id*="lblCont"]').html();
printWindow = window.open("", "", "location=1,status=1,scrollbars=1,width=650,height=600");
printWindow.document.write('<html><head>');
printWindow.document.write('<style type="text/css">@media print{.no-print, .no-print *{display: none !important;}</style>');
printWindow.document.write('</head><body>');
printWindow.document.write('<div style="width:100%;text-align:right">');
//Print and cancel button
printWindow.document.write('<input type="button" id="btnPrint" value="Print" class="no-print" style="width:100px" onclick="window.print()" />');
printWindow.document.write('<input type="button" id="btnCancel" value="Cancel" class="no-print" style="width:100px" onclick="window.close()" />');
printWindow.document.write('</div>');
//You can include any data this way.
printWindow.document.write('<table><tr><td>Contractor name:'+ Contractor +'</td></tr>you can include any info here</table');
printWindow.document.write(document.getElementById('forPrintPreview').innerHTML);
//here 'forPrintPreview' is the id of the 'div' in current page(aspx).
printWindow.document.write('</body></html>');
printWindow.document.close();
printWindow.focus();
}
觀察到按鈕「打印」和「取消」有CSS類「無印」,那麼這些按鈕將不會出現在打印。
