Thanks for your reply,My Problem is not to create display method but the Problem is how to display the sum of subtotal by this display field.So my solution is to add GroupField in the AxGridView with designed field like GoalId in my case.then in the AxGridView i create template field with footer containing label not visible in default. So in rowdatabound i do the total by the new group that known with a test in rowcreated in GoalId 's value changes .Then when i get a new group i put the value of cumul of the previous value of a the previous group and in the footer template i display the total of all rows.this is the solution and thanks so much for your help. but now the problem that i noticed that axgridview have problems after updating data with a groupby fields and with template field.it display noting in this fields

You can create a display method to compute your sum on each row. If you do so, don't forget the 'cacheAddMethod' in order not to compute it each time. This is the "historical" way. More info on display methods.

Or you can create a view and use computed column in it. It will depends on your current datamodel and query you want to run. More info on computed column in views.
