Dear Experts,

How can I validate the page using this javascript on Asp Button Control.

function PrintPanel() {
 
            var panel = document.getElementById("<%=pnlContents.ClientID %>");
 
            var printWindow = window.open('', '', 'height=700,width=1000');
 
            printWindow.document.write('<html><head><title>Trainee Appraisal Form</title>');
            printWindow.document.write('</head><body >');
           
            printWindow.document.write(panel.innerHTML);
             
            printWindow.document.write('</body></html>');
            printWindow.document.close();
           
            setTimeout(function () {
                printWindow.print();
            }, 500);
             
            return false;
        }

<asp:Button ID="Button1" runat="server" 
onclick="Button1_Click" Text="Print Only" 
OnClientClick = "return PrintPanel();" />

Thanks

This way

function PrintPanel() {
    if(Page_ClientValidate()){
      var panel = document.getElementById("<%=pnlContents.ClientID %>");
      var printWindow = window.open('', '', 'height=700,width=1000');
      printWindow.document.write('<html><head><title>Trainee Appraisal Form</title>');
      printWindow.document.write('</head><body >');       
      printWindow.document.write(panel.innerHTML);   
      printWindow.document.write('</body></html>');
      printWindow.document.close();    
      setTimeout(function () {
      	printWindow.print();
      }, 500);
    }
   return false;
}

<asp:Button ID="Button1" runat="server" <br>onclick="Button1_Click" Text="Print Only"
OnClientClick = "return PrintPanel();" />
