Edit an item outside RadGridView
When you edit an item from the collection bound to the RadGridView and the business object implements the INotifyPropertyChanged interface - the changes immediately reflect in the grid. However, this does not update the filtering, grouping and sorting of the control. In order to reapply those operations, you can replace the desired item in the collection bound the ItemsSource of the RadGridView (provided that the collection implements INotifyCollectionChanged) with a new object. Alternatively, you can also invoke the EditItem and CommitEdit methods of the Items collection. Both approaches are demonstrated in Examples 1 and 2.
Example 1: Replace an item in the collection bound to the RadGridView
var newClub = new Club("New Club");
// In the context of this example this.Clubs is a collection of Club objects, which is bound to the ItemsSource of the RadGridView
this.Clubs[0] = newClub;Example 2: Utilize the EditItem and CommitEdit methods of the Items collection
Club selectedItem = this.gridView.SelectedItem as Club;
this.gridView.Items.EditItem(selectedItem);
selectedItem.Name = "New Name";
this.gridView.Items.CommitEdit();
