[Solved] AddinNewDataItem never fired

[medialog]

Hello,

I have a GridView with ItemSource binded.

When i add by the code an element in items "AddingNewDataItem" is not fired.

Is it a bug or the event AddinNewDataItem doesn't fired when item is added by the code??

Players is ObservableCollection<Player>.

I need to preselect the last row and the second column at each insert. I don't know how to make this if AddinNewDataItem doesn't fired.

My version is Q1 2011.




public MainPage()
        {
            playersGrid.AddingNewDataItem += new EventHandler<Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs>(playersGrid_AddingNewDataItem);
        }

        void playersGrid_AddingNewDataItem(object sender, Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs e)
        {
            //Never fired
        }

        private void Button1_Click(object sender, RoutedEventArgs e)
        {
            if(playersGrid.DataContext is MyViewModel)
            {
                var viewModel = playersGrid.DataContext as MyViewModel;
                viewModel.Players.Add(new Player("jerome", 10, Position.DF, "France"));
            }
        }

Hi Jérôme,

 AddingNewDataItem fires only when the user inserts a data item - either through the New Row, or by pressing the Insert key.
