hello everyone ,i have a question longtime,that is :
if i want to create a people manager application, and if i use the
form model, the user must click the save button to save the message when he inserts one record every time,so i want to use the datagird, when user uses the datagrid,he mustn't to click save button to save the message when he inserts one record every time,he can inserts all of the record he needs,and then at the end, click save button. that is i want,but that is a new question, i am afraid that ,if one user work on this computer,and another one work on other computer, this time , the soft will be error, because user all work in the datagrid model,and they will be insert the same record at the same time, how can i get the error? let the datagrid bound or unbound the datasurce,which is the better? please tell me,thanks
