An article on creating a print preview page dynamically by using JavaScript code. You do not need to make any ASPX page to view print preview, and you can also print any portion of the print page.

Introduction

If you want to show a print preview page before printing any page, then you have to make a page like the one that currently is showing.

Or, if you want to print a particular section of that page, like only a DataGrid, HTML table, or any other section, and you also need to preview that in a separate page before printing, you have to create a separate print preview page to show, which is more difficult for you.

I have introduced a technique to avoid this problem. You do not need to create a separate page for print preview. You just use the JavaScript code in Script.js to create a print preview page dynamically. It will take less time to implement and so is faster. Hopefully, it will be helpful for you.

Background

I was developing a report module in my existing project. The report contents are generated dynamically by giving input (like generate by status, date range, etc). And, there is a print button to print. My client wanted to view a print preview page before printing, but we had already completed this module then. It was a really hard situation for my developers to build a print preview page for all the reports. I got this idea during that situation.

Using the code

You will just add the Script.js file in your project. The following code has been written in that file.

Source code

//Generating Pop-up Print Preview page
function getPrint(print_area)
{
    //Creating new page
    var pp = window.open();
    //Adding HTML opening tag with <HEAD> … </HEAD> portion 
    pp.document.writeln('<HTML><HEAD><title>Print Preview</title>')
    pp.document.writeln('<LINK href=Styles.css type="text/css" rel="stylesheet">')
    pp.document.writeln('<LINK href=PrintStyle.css ' + 
                        'type="text/css" rel="stylesheet" media="print">')
    pp.document.writeln('<base target="_self"></HEAD>')

    //Adding Body Tag
    pp.document.writeln('<body MS_POSITIONING="GridLayout" bottomMargin="0"');
    pp.document.writeln(' leftMargin="0" topMargin="0" rightMargin="0">');
    //Adding form Tag
    pp.document.writeln('<form method="post">');

    //Creating two buttons Print and Close within a HTML table
    pp.document.writeln('<TABLE width=100%><TR><TD></TD></TR><TR><TD align=right>');
    pp.document.writeln('<INPUT ID="PRINT" type="button" value="Print" ');
    pp.document.writeln('onclick="javascript:location.reload(true);window.print();">');
    pp.document.writeln('<INPUT ID="CLOSE" type="button" ' + 
                        'value="Close" onclick="window.close();">');
    pp.document.writeln('</TD></TR><TR><TD></TD></TR></TABLE>');

    //Writing print area of the calling page
    pp.document.writeln(document.getElementById(print_area).innerHTML);
    //Ending Tag of </form>, </body> and </HTML>
    pp.document.writeln('</form></body></HTML>'); 
}

The getPrint(print_area) function takes the DIV ID of the section you want to print. Then, it creates a new page object and writes the necessary HTML tags, and then adds Print and Close buttons, and finally, it writes the print_area content and the closing tag.

Call the following from your ASPX page. Here, getPrint('print_area') has been added for printing the print_area DIV section. print_area is the DIV ID of the DataGrid and the other two will work for others DIVs. Whatever areas you want to print must be defined inside of DIV tags. Also include the Script.js file in the ASPX page.

'calling getPrint() function in the button onclick event
btnPrint.Attributes.Add("Onclick", "getPrint('print_area');")
btnTablePP.Attributes.Add("Onclick", "getPrint('Print_Table');")
btnPagepp.Attributes.Add("Onclick", "getPrint('Print_All');")

Download the source code to get the getPrint() function.

I have used the following code in the demo project to generate a sample DataGrid:

Private Sub PopulateDataGrid()
    'creating a sample datatable
    Dim dt As New System.Data.DataTable("table1")
    dt.Columns.Add("UserID")
    dt.Columns.Add("UserName")
    dt.Columns.Add("Phone")
    Dim dr As Data.DataRow
    dr = dt.NewRow
    dr("UserID") = "1"
    dr("UserName") = "Ferdous"
    dr("Phone") = "+880 2 8125690"
    dt.Rows.Add(dr)
    dr = dt.NewRow
    dr("UserID") = "2"
    dr("UserName") = "Dorin"
    dr("Phone") = "+880 2 9115690"
    dt.Rows.Add(dr)
    dr = dt.NewRow
    dr("UserID") = "3"
    dr("UserName") = "Sazzad"
    dr("Phone") = "+880 2 8115690"
    dt.Rows.Add(dr)
    dr = dt.NewRow
    dr("UserID") = "4"
    dr("UserName") = "Faruk"
    dr("Phone") = "+880 2 8015690"
    dt.Rows.Add(dr)
    DataGrid1.DataSource = dt
    DataGrid1.DataBind()
End Sub

Use the following code in a separate style sheet page. See PrintStyle.css if you want to hide the Print and Close buttons during printing.

#PRINT ,#CLOSE
{
    visibility:hidden;
}

Points of interest

I was facing a problem during print. Print was not working the first time I clicked it. I solved that problem by reloading by using location.reload(true); on that page.
