推荐答案
我不知道您的确切要求，但是如果您想为Page进行打印预览，那么最简单的解决方案是编写如下的Java脚本
我不记得从哪里找到下面的Javascript了很长时间，但是它一直对我有帮助
I dont know your exact requirement ,but if you want a print preview for your Page then the most simplest solution is to write a Javascript as below
i dont remember from where i found the below Javascript it was quite a long time , but it has always worked wondoers for me
<script language="javascript" type="text/javascript">
function PrintContent() {
printWindow = window.open("", "mywindow", "height=650,width=999,scrollTo,resizable=1,scrollbars=1,location=1");
var strContent = "<html><head>"; // If you use this script inside <head> on the page, there might be error. So I am keeping inside body (becaue of <head>)
strContent = strContent + "<title>Print Preview</title>";
strContent = strContent + "<link href='../../App_Themes/Default/Page.css' type='text/css' rel='Stylesheet' />";
strContent = strContent + "</head>";
strContent = strContent + "<body>";
strContent = strContent + "<div style='width:100%;text-align:left;'>";
strContent = strContent + "<img alt='Imageid' src='../../Images/Logo.jpg' />";
strContent = strContent + "</div>";
strContent = strContent + "<div style='width:95%;text-align:right;'>";
strContent = strContent + "<img alt='PrintID' title='Print' class='PrintIcon' src='../../Images/printicon.jpg' onclick='window.print()' />";
strContent = strContent + "</div>";
strContent = strContent + "<div style='width:100%;'>";
strContent = strContent + document.getElementById('PrintArea').innerHTML;
strContent = strContent + "</div>";
strContent = strContent + "</body>";
printWindow.document.write(strContent);
printWindow.document.close();
printWindow.focus();
return false;
}
</script>
使用完javascript之后，您将在Javscript中看到以下内容，如下所示:
Once you done with javascript ,you will see the line inside a Javscript as below
strContent = strContent + document.getElementById('PrintArea').innerHTML;
PrintArea是您需要打印的区域，因此所有需要打印的页面内容都应位于打印区域"下
如果您有多个区域，则可以按照以下内容编写
the PrintArea is the one which you need to print , so all the content of page which need to be printed should come under Print Area
if you have multiple area you can write as per below
strContent = strContent + document.getElementById('printHeader').innerHTML;
strContent = strContent + document.getElementById('printTitle').innerHTML;
strContent = strContent + document.getElementById('divApplcicationStatus').innerHTML;
strContent = strContent + document.getElementById('Print5').innerHTML;
strContent = strContent + document.getElementById('Print1').innerHTML;
strContent = strContent + document.getElementById('Print2').innerHTML;
然后在您要单击的按钮上单击以加载打印预览，请按照
amd then in your button on which click you want to load a print preview you do following
<asp:Button ID="btnPrint" runat="server" CssClass="button" Text="Print" OnClientClick="return PrintContent();" /></td>
<td style="width: 10%">
