Is there a quick and dirty way to add a print button to a web form such that it will allow the user to print the contents of just one panel on the form?  VB  if you please if possible

Hi jglazer63,
>>..will allow the user to print the contents of just one panel on the form
Yes, you can just create a new dummy pop-up window and include the rendered HTML content that resides inside panel that you need. That is the easier way to print out the preferred content in the web page. You can modify it based on your real output that needed.
<html>
<script type="text/javascript">
function printMe()
{
var content=document.getElementById('yourPanelClientID');
 
//open blank page and put the rendered HTML text inside
w=window.open('about:blank');
w.document.open();
w.document.write("<html>" + content.innerHTML);
w.document.writeln("<script>window.print()</"+"script>");
w.document.writeln("</html>");
w.document.close();
}
</script>
Other Content bla bla bla <br>
<div id="yourPanelClientID">
YOUR Panel Content here in web form ...
</div>
<input type=button id=btn onclick="printMe()" value="Print">
</html>

Open in new window

Well this is close but something is screwy.  When I hit the print button it opens another window but it renders the entire page.  Well to be more precise, it renders most of the page most of the time, other times it only renders a piece.  I've even seen it get distorted.  I know I coded the ID of the panel alone.  Any ideas here?

Nevermind.  I worked it out.  It seems that even though you ID the panel as "Panel1" when it is created in HTML its ID becomes "ctl00_pvt_main_Panel1".  If I use that ID all is well.  

Thanks for the help!!

I am using similar code trying to print contents of a panel. Basically within the panel I have an image that is 2550 X 3300 which is the size of a 8 X 11 sheet of paper. The only issue that I am having is that when it prints there is a blank 2nd page. Do you have any idea of how to fix this issue?

</head>
       <script type = "text/javascript">
           function PrintPanel() {
               var panel = document.getElementById("<%=pnlContents.ClientID%>");
               var printWindow = window.open('', '', 'height=400,width=800');
               printWindow.document.write('<html><head><title>                      </title>');
               printWindow.document.write('</head><body >');
               printWindow.document.write(panel.innerHTML);
               printWindow.document.write('</body></html>');
               setTimeout(function () {
                printWindow.print();
            }, 500);
            return false;
        }
    </script>
