Which line is getting the error? Look back to see what you are using on that line that hasn't been set up. For example, if window.open fails, then docprint will be null, and the next line will get the error you describe.

I think this line throwing Exception
document.getElementById("print_content").innerHTML;
Don't use innerHtml
Use .Value
It will work fine

Hi,
As I think, you are missing ";" semicolon while calling the javascript function that's why it is not able to call the function.
Try this:

ASP.NET

<asp:button id="btnPrint" runat="server" text="Print" onclientclick="javascript:Clickheretoprint();" height="29px" style="font-weight: 700" width="70px"/>

Or

ASP.NET

<asp:button id="btnPrint" runat="server" text="Print" onclientclick="Clickheretoprint();" height="29px" style="font-weight: 700" width="70px" />

declare a hidden field variable and store the value to hiddenfield variable and print from that variable as i modified the code

JavaScript

<script type="javascript" language="javascript">
        function Clickheretoprint() {
            var disp_setting = "toolbar=yes,location=no,directories=yes,menubar=yes,";
            disp_setting += "scrollbars=yes,width=650, height=600, left=100, top=25";
           // var content_vlue = document.getElementById("print_content").innerHTML;
  var content_vlue = document.getElementById("hiddenfieldID").value;
            var docprint = window.open("", "", disp_setting);
            docprint.document.open();
            docprint.document.write('<html><head><title>Inel Power System</title>');
            docprint.document.write('</head><body  önload="self.print()"><center>');
            docprint.document.write(content_vlue);
            docprint.document.write('</center></body></html>');
            docprint.document.close();
            docprint.focus();
        }
</script>

Hope this will work
