Hi,
I have a gridview populated from a List<> and i want to be able to modify, delete or to add a new row (by clicking on "Add new row " at the bottom of the grid) directly on grid . After the user fills out all columns, he will click on a save button outside the grid. Now, i want to know how to iterate between gridview rows to know wich rows were added an wich were modified, deleted....
And depeding on the row state, i'll do an insert, update or delete on the Database.

Thank u very much!

Hello Yan St-Yves,

RadGridView is not responsible for tracking the state of each record. This is responsibility of your data source. For instance, the Microsoft DataTable class has GetChanges method returns deleted, added or modified rows. There is two approached two resolve your case:

  • You can use DataTable class instead of LIst<T> as data source
  • You should extend your data source to support tracking of its items' states by storing changed records in additional collections.
