i did google search on "webgrid sort indicator" , came result http://prokofyev.blogspot.com/2011/01/sort-indicator-in-systemwebhelperswebgr.html

basically, person uses jquery add in sort direction image.

<script type="text/javascript">     $('thead > tr > th > a[href*="sort=@grid.sortcolumn"]').parent()     .append('@(grid.sortdirection == sortdirection.ascending ? "u" : "d")'); </script>

(as added bonus, tested myself, can copy , paste code (the link 1 picture instead of code sample :( ...) replace u , d whatever want display instead.

hope helps.
