[Solved] Row's header (rowindicator)

[Janne]

Is there a way to set row's header color (or image) on RowEditEnded event?
I am in a need to visually show to user which rows have been modified since last
db update and row's header would be a nice place for that.

Regards

Hi Janne,

The following code asumes that you are binding the grid to a collection of Person objects.
It will set background color of the RowIndicator  to Red for the edited rows.
Note that we keep the edited records in a 'dirtyData' collection. This allows persistence of  our formatting even on sorting , grouping and scrolling the grid.

public MainPage()
        {
            InitializeComponent();
            this.RadGridView1.ItemsSource = Person.GetSampleObservableCollectionOfPersons();
            this.RadGridView1.RowEditEnded += new EventHandler<Telerik.Windows.Controls.GridViewRowEditEndedEventArgs>(RadGridView1_RowEditEnded);
            this.RadGridView1.RowLoaded += new EventHandler<RowLoadedEventArgs>(RadGridView1_RowLoaded);

        }

        void RadGridView1_RowLoaded(object sender, RowLoadedEventArgs e)
        {
            if (dirtyData.Contains(e.Row.DataContext as Person))
            {
                e.Row.ChildrenOfType<IndicatorPresenter>().First().Background = new SolidColorBrush(Colors.Red);
            }
        }

        List<Person> dirtyData = new List<Person>();

        void RadGridView1_RowEditEnded(object sender, Telerik.Windows.Controls.GridViewRowEditEndedEventArgs e)
        {
            if (e.Row.DataContext as Person != null)
                dirtyData.Add((Person) e.Row.DataContext);
        }

In case you have troubles adapting this to your projects , just let me know.
