jQuery Grid Plugin - jqGrid

I am defining my jqgrid explicitly HTML so I can hook iup server-side ASP code to it.  I need help with the syntax for adding formatoptions to my edit actions column.  I've tried everything but just can't figure it out.  Here's my code so far (which doesn't work):

<trirand:JQGridColumn HeaderText="Edit $" ShowToolTip="false" EditActionIconsDeleteEnabled="false" EditActionIconsColumn="true" Width="50" >
 <Formatter formatoptions="afterSave: function (rowid) { $('#grdPlanLines').trigger('reloadGrid');" />
</trirand:JQGridColumn>

I can find lots of syntax examples if I define the colmodel via jquery, but then I can't write server-side asp code against the grid.  If I have to switch to a jquery-based colmodel definition in order to use formatoptions, please answer the riddle to using server-side asp in this case.

Thanks!
