<script type="text/javascript">
$(function () {
$('[id*=grd_dist_master]').prepend($("<thead></thead>").append($(this).find("tr:first"))).DataTable({
"responsive": true,
"sPaginationType": "full_numbers"
});
});
</script>
Change the above with the below.
<script type="text/javascript">
$(function () {
$('[id$=grd_dist_master]').prepend($("<thead></thead>").append($(this).find("tr:first"))).DataTable({
"responsive": true,
"sPaginationType": "full_numbers"
});
});
</script>
As you are using master page find id that ends with grd_dist_master.
