    how can i remove selected row and how can i add new one to the top? Im writing simple email app, and i need to add new rows to the top when messages come, and remove selected row (because someone can delete it, or move to another folder). I know there is an event Deleted and Deleting, but that is not what i need.

    Hello Zbigniew,

    You should remove the items from your source collection and the grid will pick this changes and update its UI.

    For example if you want to remove the selected item you can use the following code:

    If you want to add an item as a first row you should insert it in the collection that the grid is bound to:
    ((IList)this.OrdersControl.ItemsSource).Add(new MailMessage())
    assuming that your object is MailMessage and the source collection is ObservableCollection.

    Also you may want to look at our Step-By-Step tutorial for Silverlight illustrating this scenario as well as many others.
