Can't get form to print from JavaScript function.

Hello,
    This is a simple one, but I don't know what I'm doing incorrectly. I'm trying to print a web form (.aspx) using a server side button control. I have the following code on the aspx page on the Page_Load event.

            If Not IsPostBack Then
                btnPrint.Attributes.Add("onclick", "PrintPage();")
            End If


Which should add onclick="PrintPage" to the client side html that is eventually generated.

In the source, I have the following in the html header.

<head runat="server">
    <title>Page Title</title>
    <script language ="javascript">
        Function PrintPage(){      
                                        window.print                            }
   
    </script>
</head>

I have viewed source on the html and it looks correct, but the page errors out whenever I click on the button. I have no idea why. Any ideas are appreciated. Thanks,

Why not add it in the client side code :
<asp:Button ID="btnPrint" runat="server" Text="Print" OnClientClick="PrintPage();" />
and then you have the javascript function:
<script type="text/javascript">
function PrintPage()
{
         window.print();
}
</script>

Thanks for the suggestion. I wasn't using onClientClick (as you suggest), so I thought that may have been the problem. However, there is no difference. The page errors out in exactly the same manner. The only thing I can think of is that I have hit a security restriction of some kind. I even tried changing the function to display a simple alert and it refuses to work. It's like it can't see the javascript function at all, but I don't see why that would be the case.

K, I got it. OnClientClick is right, but it didn't like the semi-colon after the PrintPage call. So, I tried it like so, and it worked just fine

function PrintPage(){
                if (window.print)
                window.print()
            }


<asp:Button ID="btnPrint" runat="server" Text="Print This Page" OnClientClick="PrintPage()" /><br />
