Printing From a SharePoint Visual Web Part

by | Jun 4, 2012 | Design, SharePoint, Visual Studio 2010 - C# | 3 comments

I recently built a SharePoint (SP) Visual Web Part (VWP) with two calendar controls and a literal control. The calendar controls are used to filter the content of a specific list and the results are displayed in the literal control.

The literal control only has the “text” property for its content and no formatting attributes.  You can build your content in the literal control with html tags and, in that way, get the display results you want.

So – how do I get my nicely formatted content printed? More specifically, how do I get the literal control content printed easily without 1) cutting and pasting into a document; 2) selecting the desired text and chooding “Selection” from the print dialog; or 3) printing the page without the calendar controls on the printed page?

If you have looked around the web you probably know that using javascript in some fashion is the answer. Some of the soloutions “out there” implement a “.js” file, modify the master page, or implement some combination with jQuery.

I tried a few less complicated approaches before hitting on the one that works well for me.

Approach 1. Assign print attribute to an existing button.

In this approach you create a button in your visual web part. On PageLoad you add an attribute to the button that adds the “onclick” method with the “window.print” action.

protected void Page_Load(object sender, EventArgs e)
if (Page.IsPostBack == false)
btnPrint.Attributes.Add(“onclick”, “javascript: window.print();”);

When you click ‘btnPrint’ then the print dialog is generated and you can print the page.

I think this is a very common approach because it is all over the web and is very easy to implement.

The problem with this approach is that it prints the entire page. So if you have other controls or text on the page you don’t want printed (like my calendar controls) this approach will not work.

Approach 2. Create javascript that prints the content you want and assign to an existing button.

So another approach I took was to replace “window.print()” with a combination of javascript and normal “code behind” that would get print just the contents of the literal control.

btnPrint.Attributes.Add("onclick", "javascript: var; self.focus();;win.document.write('');win.document.write('" + literalcontrol.text + "');win.document.write('');win.document.close();win.print();win.close();");

The above code will not compile unless it is properly concatenated or on one line. It is displayed like this for readability.

So what is the problem with this code? Well, unfortunately what gets inserted as  literalcontrol.text is not dynamic. This button attribute is set on page load and whatever is in the literal control at that point is what will be writtent into the html document and printed.

Approach 3. Write the print action into the literal control text.

This was a winning approach for me. It is basically Approach 2 but instead of the javascript being assigned to a button on pageload, I create it (and recreate it) with a link in the literal control itself!

string newText = "Some stuff that was created in code using my calendar control filters.";</span>

string rpt = "font size="4" face="verdana"&gt;Counts by Reason";

rpt = rpt + "<span style="font-family: verdana; font-size: small;">
" + newText + "</span>";

newText = "<span style="font-size: medium;">Results</span><span style="font-size: x-small;">
</span><span style="font-size: small;">" + newText + "</span>";

string href = "javascript: var;self.focus();;win.document.write(\"" + rpt + "\");win.document.close();win.print();win.close();";

string link = "<a href="&quot;; + href + &quot;"><span style="text-decoration: underline;">Print...</span></a>";

newText = newText + link;
LiteralReport.Text = newText;

In the above code I define string “rpt” so that I can put in a report header text with a different format from that which is put in the literal control. Also, the rpt variable is really “bookended” with ‘html’ and ‘body’ tags, but unfortunately those tags do not displayed in this post.

To minimize confusion with all of the single and double quotes, I build up my link one component at a time (rpt, then href, then link).

The end result is that the “Print…” link creates a temporary html page with the content I want with the format I want and generating the print dialog box as well. Once printed, the temporary html document disappears and you are back to the page where you started.

    Hello. I am trying to place a button on my SP page that only prints those docs that are selected AND prints in a specific InfoPath View AND where my users don’t have to select a printer. Is that possible? Been searching for 2 weeks now.

      Unfortunately I don’t have a solution for you. It sounds like the approach to take is to create/modify an ECB or a list control. There may be a javascript out there that will print a specific printer, but I can’t help you there.

      Good Luck!

    Hey there and first of all thanks for the advice given here! Actually,
    your solution seems to be nearly exactly what I need 🙂

    I got a in some ways similar question opened over at stack exchange

    and perhaps you could help me out to get your solution working for my
    scenario?! Would be great to hear from you! Feel free to drop me a line
    via email or something.
