dataGridView custom sorting
                            
                         
                        
                     
                 
                
                    I have a column which can take values like these: 
152,678 
22,001 
3,571 
78,055 
Now thats how it would be sorted right now, seen as strings 
But I want to sort them as Integers. 
(The value "N/A" can also be present, i want that to count as zero.) 
Right now the column is Sortable: Automatic 
I've read the CustomSorting article at MSDN, but I dont really get it fully. 
How should I do this?
