我有一个来自数据库的 gridview，问题是当用户单击打印按钮时，我想打印整个页面，gridview 的每一行以给定格式打印为 1 A4 尺寸页面上的 3 行。
gridview
Printing format
如果你想使用 javascript 那么你可以尝试这个
function printItn() {
//In my case i have append gridview in Panel that y..you can put your contentID which is you want to print.
var printContent = document.getElementById('<%= pnlForm.ClientID %>');
var windowUrl = 'about:blank';
var uniqueName = new Date();
var windowName = 'Print' + uniqueName.getTime();
// you should add all css refrence for your Gridview. something like.
var WinPrint= window.open(windowUrl,windowName,'left=300,top=300,right=500,bottom=500,width=1000,height=500');WinPrint.document.write('<'+'html'+'><head><link href="cssreference" rel="stylesheet" type="text/css" /><link href="gridviewcssrefrence" rel="stylesheet" type="text/css" /></head><'+'body style="background:none !important"'+'>');
WinPrint.document.write(printContent.innerHTML);
WinPrint.document.write('<'+'/body'+'><'+'/html'+'>');
WinPrint.document.close();
WinPrint.focus();
WinPrint.print();
WinPrint.close();
}
