task management system in asp.net

I have done before some time this type of requirement.
you can do it with the help of Gridview. make the Task table like this type

TaskId        EmployeeID      Accept/Reject 
1                  12                        1 is Task Create
1                   13                      2  is Task Accept
                                                3 is task Complete
                                                4 is Task Reject


and some work on girdveiw_rowDataboud event.

{

if task is accept then show another image ...so on
}
