Grid View in Multiuser Environment
i am working with a Purchase Order module in ASP.2., in this module i have to create a webform for data entry, which has two parts, one is header, details like p.o no., customer name, date etc, other one is details part, a grid view in which user can add required product code, qty and rate.
But how to populate this gridview? i can't bind this grid view with a physical table bcz this is multiuser form. And i have to save datas entered in this grid somewhere before saving, because if the internet connection gets disconnected, in next login, the data entered have to be restored.
i did read somethings about collections, using this we can bind a collections to the grid view. by adding this collection to asp.NET profile we can save this collection to the server and can retrive user wise. but i don't know, this is correct or not.
can i create a datasource in client mechine and bind to gridview?
i think if it is in client side, performance wise its better.
can u plz suggest a good method to solve theese problems..
thanks in advance
