Hello ,

I have an pop up which open on button click event through which adding some data.The code for opening pop up is as follows

<script type="text/javascript">
        function GetData() {
            
            var url = "abcd.aspx";
            var popupSetting = "center=yes,height=400,width=550,toolbar=no,directories=no,status=no,scrollbars=no,resizable=0,menubar=no,location=no,minimizable=no,maximizable=no,dialog=yes,modal=yes";
            var pmx = window.open(url, 'abcd', popupSetting);
        }
    </script>

And making the parent page to referesh while inserting or updating the record from pop up window.the code is as follows.

<script type="text/javascript">
        function Close() {
            window.opener.location.reload();

            

        }
