Am new to jqGrid for about 2 hours now, 
I had added deleting from a row successfully. so i.e.
colModel: [
 .....
name: 'actions', index: 'actions', width: 105, editable:false, formatter: 'actions',
formatoptions: {
    keys: true,
    editbutton: false,
    delOptions: { url: getURL('Action') + 'method?f='+$('#id').val()}
   }
],
This shows a general trash can, but I wondering if its possible to show your own button?
This http://www.trirand.com/jqgridwiki/doku.php?id=wiki:custom_buttons looks quite promising,
But I do not think it would work with the code I have pasted above and I don't really want to change it as the functionality from JS to C# is working OK.
Thanks
