Error - mbox_ascx' does not contain a definition for 'lnkRecordDelete_

Question

Hi

 I am getting error - 'mbox_ascx' does not contain a definition for 'lnkRecordDelete_Click' and no accessible extension method 'lnkRecordDelete_Click' accepting a first argument of type 'mbox_ascx' could be found (are you missing a using directive or an assembly reference?)

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MBox.ascx.cs" Inherits="Payroll.MBox" %>

<script type="text/javascript">

    var swalInit = swal.mixin({
        buttonsStyling: false,
        confirmButtonClass: 'btn btn-primary',
        cancelButtonClass: 'btn btn-light'
    });


    function ShowPopup_Redirect(heading, body, type, url) {
        swalInit.fire({
            title: heading,
            text: body,
            type: type,
            position: 'top',
            allowOutsideClick: false;
            }
        });
    }
</script>
