Hi amar,

Inorder to pass value from popup window to parent page Hiddenfield use JavaScript.

Refer below code.

Parent Page

<script type="text/javascript">
    function popitup(url, windowHeight, windowWidth) {
        var centerWidth = (window.screen.width - windowWidth) / 2;
        var centerHeight = (window.screen.height - windowHeight) / 2;
        newwindow = window.open(url, 'name', 'resizable=0,scrollbars=yes,width=' + windowWidth +
                ',height=' + windowHeight +
                ',left=' + centerWidth +
                ',top=' + centerHeight);
        //if (window.focus) {  newwindow.focus() }
        return false;
    }
</script>
<asp:HiddenField ID="hdnlnkEdit" runat="server" Value="Test" />
<a href="Comments.aspx" onclick="return popitup('Comments.aspx?provID=1&StatusDescID=1&StatusCategory=1&Name=Test','650','1270')">
    Test</a>

Child Page

<script type="text/javascript">
    window.onload = function () {
        if (window.opener != null && !window.opener.closed) {
            var txt = window.opener.document.getElementById("<%= hdnlnkEdit.ClientID%>");
            txt.value = "Krishna";
        }
    }
</script>
