Hi,
I am having same javascript as below and I am using that in my Master Page.
But when I try to print;
It is showing me error on line:-
printWindow.document.write(printContent.innerHTML);

Thanks.

 <script type="text/javascript">
                function printPartOfPage() {
                    var printContent = document.getElementById("ContentPlaceHolder2");
                    var windowUrl = 'about:blank';
                    var uniqueName = new Date();
                    var windowName = 'Print' + uniqueName.getTime();
                    var printWindow = window.open(windowUrl, windowName, 'left=50000,top=50000,width=0,height=0');

                    printWindow.document.write(printContent.innerHTML);
                    printWindow.document.close();
                    printWindow.focus();
                    printWindow.print();
                    printWindow.close();

do this pls

C#

NavigateUrl="javascript:window.printPartOfPage(this)"

and pre configure your function that

JavaScript

function printPartOfPage(strid) {
             var printContent = strid;
             
                    var windowUrl = 'about:blank';
                    var uniqueName = new Date();
                    var windowName = 'Print' + uniqueName.getTime();
                    var printWindow = window.open(windowUrl, windowName, 'left=50000,top=50000,width=0,height=0');
 
                    printWindow.document.write(printContent.innerHTML);
                    printWindow.document.close();
                    printWindow.focus();
                    printWindow.print();
                    printWindow.close();
