Visualforce Page Rendered as PDF

Visualforce Page Rendered as PDF

A few years ago I started generating PDF invoices and receipts directly within Salesforce. Since invoices or receipts may have many rows of data and the data may span multiple pages, I decided to include a page counter in the margin of each rendered page.

Yesterday I was creating another Visualforce PDF page and I needed to include a page counter again. I had some difficulty recalling exactly how to build that logic and thought it would make sense to post it on InteractiveTies.com so I could find it more easily the next time I need it.

As I began thinking about how to demonstrate the logic I thought it made more sense to create a simple template for other developers to use as they consider building out Visualforce pages that render as PDF.

In this example we will be using a Cascading Style Sheet (CSS) as a static resource. You may download the file here. The content of the CSS file is as follows:

*/
body {
	font-family: Arial, Helvetica, sans-serif;
}
@page {
	size: landscape; /*landscape orientation*/
	/*page numbers in the bottom center of each page in the pdf document*/
	@bottom-center {
		content: "Page " counter(page) " of " counter(pages);
		font-family: Arial, Helvetica, sans-serif;
		font-size: 80%;
	}
	/*placeholders for other content areas*/
	@bottom-right {
		content: "Bottom Right";
		font-family: Arial, Helvetica, sans-serif;
		font-size: 80%;
	}
	@bottom-left {
		content: "Bottom Left";
		font-family: Arial, Helvetica, sans-serif;
		font-size: 80%;
	}
	@top-right {
		content: "Top Right";
		font-family: Arial, Helvetica, sans-serif;
		font-size: 80%;
	}
	@top-center {
		content: "Top Center";
		font-family: Arial, Helvetica, sans-serif;
		font-size: 80%;
	}
	@top-left {
		content: "Top Left";
		font-family: Arial, Helvetica, sans-serif;
		font-size: 80%;
	}

}

We need to create the static resource in Salesforce before we create our Visualforce page. Navigate to Setup > Develop > Static Resources then click the "New" button on the resulting page. Upload the file and provide these additional details:

• Name: pdfStyle
• Cache Control: Public

Now that the CSS file has been uploaded we may create the Visualforce page that will actually render as a PDF. Go to Setup > Develop > Pages and click the "New" button. The Visualforce page code:

<apex:page renderAs="pdf">

	<div align="right"><strong>Date</strong>: {!DAY(Today())} {!CASE(MONTH(Today()), 1, 'January', 2, 'February', 3, 'March', 4, 'April', 5, 'May', 6, 'June', 7, 'July', 8, 'August', 9, 'September', 10, 'October', 11, 'November', 12, 'December', 'Unknown')} {!YEAR(Today())}</div>

	<p>You can render any page as a PDF by adding the renderAs attribute to the &lt;apex:page&gt; component, and specifying &quot;pdf&quot; as the rendering service.</p>
	<p>Visualforce pages rendered as PDFs will either display in the browser or download as a PDF file, depending on your browser settings.</p>
	<table align="center" style="border: 1px solid #6699CC;">

			<td style="background-color: #6699CC; color: #FFFFFF; font-size: 200%; padding: 10px;">NOTES</td>
			<td>
				<ul>
					<li>Create a CSS file for your PDF styles and include it using the &lt;apex:stylesheet&gt; tag.</li>
					<li>Within that CSS file be sure to include items like the orientation of the generated page and a page counter (if desired):
<pre><code>@page {
	size: landscape; /*landscape orientation*/
	/*page numbers in the bottom center of each page in the pdf document*/
	@bottom-center {
		content: "Page " counter(page) " of " counter(pages);
		font-family: Arial, Helvetica, sans-serif;
		font-size: 80%;
	}
}</code></pre></li>
					<li>You may use inline CSS declarations but be sure to consider any limitations: www.salesforce.com/us/developer/docs/pages/Content/pages_output_pdf_considerations.htm</li>
				</ul>

Accessing the Visualforce page renders the following PDF:
