jqGrid show an 'edit' icon for in line editing

Question

I am using the jqGrid with inline editing option. I want to show an edit icon if the cell does not have any values.

So I write a formatter:

 function aFo         


        

Answer 1

This will show an "edit" icon instead of "you can edit this" in the grid

function aFormatter(cellvalue, options, row) {
   if(cellvalue == null) {          
      return ''
   } else {
      return cellvalue;
   }
}
