Thanks for your attention dear AlbinAbel !
but I think you write the way for ASP.NET, isn't it?
I want to do it in C# applications...

Thanks AlbinAbel!
but I mean can it done automatically like when we use dataTable assigned to dataGridView?
however I know that it can be done manually with get tracking of changes on a dataGridView object (by it's events) !

There is not any error!
actually, if you set it's DataSource property to a DataTable object, you can simply apply changes to database by calling dataAdapter1.Update(datatable1) !! but is it possible to use LINQ query for it's DataSource property, and (by any way) apply all DataGridView changes to database?

Thanks for your advice !
