How to print Content Page Information from Master Page using JavaScript



In previous posts we have seen how to print a page using Javascript in a normal web page. In this post I will be providing some examples on how to print the page or a part of page when the page includes Master Page also.

In previous posts, we have design a web page which is similar to a news postal page. It will show latest news into the page with header, footer and menu. Let us design the same page with the same concept. The following code shows the master page (MasterPage.Master) snippet:
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="MasterPage.master.cs" Inherits="Printing.MasterPage" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
    <title>Print with Master Page Sample</title>

<body>
<form id="form1" runat="server">
    <div id="header">
        <div style="height:60px;">

There is no c# code as we are doing nothing with code behind. The next one is the content page script (MasterPagePrint.aspx) which is using this master page.
<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.Master" AutoEventWireup="true" CodeBehind="MasterPagePrint.aspx.cs" Inherits="Printing.MasterPagePrint" Theme="Default" %>

        <p>A benchmark index of Indian equities markets Tuesday rose in noon trade, helped by strong earnings reported by corporates. Gainers in front-line stocks were led by IT and telecom firms. The 30-scrip sensitive index (Sensex) of the Bombay Stock Exchange (BSE), which opened at 18,983.2 points, was ruling at 19,008.28 points -- up 126.03 points or 0.67 % from its previous close at 18,882.25 points.</p>
        <p>The 50-scrip S&P CNX Nifty of the National Stock Exchange too was in the green, trading 36.55 points or 0.65 % higher at 5,691.3 points.</p>
        <p>Broader markets were, however, trading dull, with the BSE midcap index ruling 0.24 % up and the BSE smallcap index trading 0.34 % higher.</p>
        <p>Realty, power and energy stocks saw some selling, while gains were seen in IT and telecom scrips.</p>
        <p>The market breadth was positive, with 1,431 stocks advancing compared to 1,133 scrips on the decline, while 107 stocks remained unchanged.</p>
        <p>Among gainers on the Sensex were TCS, Wipro, Cipla and Tata Motors, while the losers included Tata Power, Reliance Infra, Jindal Steel and DLF.</p>
        <p>Most other Asian stock markets were ruling higher Tuesday, except the Chinese stocks markets which continued to loose after the Chinese central bank's latest move to tighten monetary policy cast a gloom on trading.</p>
        <p>The Chinese Shanghai Composite index shed 0.44 % to trade at 2,694.68 points, while Hong Kong's Hang Seng was ruling 0.75 % higher at 24,339.27 points.</p>
        <p>The Japanese Nikkei closed flat at 10,518.98 points.</p>

As you see in these scripts, we have header, footer and in the right side we have some advertisement and related links. The output of the screen looks like –

Page layout which uses Master Page

Our requirement is to print the news details which shows in the content page using Javascript.

Normally in real scenario, the master page will have a print button (as it is common place) to print whatever shows on the content page. In our example also, we have a print button in the master page and that needs be used to print the web page content coded in the content page.

If you look at the master page print button script (line #43), I am calling a Javascript function PrintContent() which required to be implemented to print the content web page information.

Include this Javascript function in the Master Page
<script language="javascript" type="text/javascript">
function PrintContent() {
    printWindow = window.open("", "mywindow", "location=0,status=0,scrollbars=1,resizable=1");

    var strContent = "<html><head>";
    strContent = strContent + "<title" + ">Print Preview</title>";
    strContent = strContent + "<link href=\"App_Themes/Default/Default.css\" type=\"text/css\" rel=\"stylesheet\" />";
    strContent = strContent + "</head><body>";
    strContent = strContent + "<div style='width:100%;text-align:right;'>";
    strContent = strContent + "<input type='button' id='btnPrint' value='Print' style='width:100px' onclick='window.print()' />";
    strContent = strContent + "<input type='button' id='btnCancel' value='Cancel' style='width:100px' onclick='window.close()' />";
    strContent = strContent + "</div>";
    strContent = strContent + "<div style='width:100%;'>";

    var newsDiv = document.createElement('div');
    newsDiv.innerHTML = document.getElementById('news').innerHTML;
    for (var i = 0; i < newsDiv.childNodes.length; i++) {
     if (newsDiv.childNodes[i].id == 'newsRelatedAd')
        newsDiv.childNodes[i].className = "Invisible"; //newsDiv.removeChild(newsDiv.childNodes[i]);
    }

    strContent = strContent + newsDiv.innerHTML;
    strContent = strContent + "</div>";
    strContent = strContent + "</body>";
    printWindow.document.write(strContent);
    printWindow.document.close();
    printWindow.focus();
}
</script>
The output of the print will be as follows

Print output from the Content Page (Printing from Master Page)

The Next post will provide more in depth understanding of how to print different parts of page using Javascript when Master Page, User Control, used
