Group panel drag-and-drop broken

[Brian Lam]

If the RadGridView is in a RadWindow and its theme is set on the Loaded event, you can no longer drag-and-drop the group panel cells (i.e. to reorder them). I'm able to reproduce this bug in both versions 2011.1.405.1040 and Q2 2011. Here's some sample code to reproduce the problem:

public partial class MainPage : UserControl
{
    private RadWindow _window;
    private RadGridView _gridView;

    public MainPage()
    {
        InitializeComponent();

        _gridView = new RadGridView()
        {
            ItemsSource = Enumerable.Range(1, 100)
        };
        _gridView.Loaded += GridView_Loaded;

        _window = new RadWindow()
        {
            Content = _gridView
        };
        _window.Show();
    }

    void GridView_Loaded(object sender, RoutedEventArgs e)
    {
        StyleManager.SetTheme(_gridView, new Office_BlueTheme());
    }
}

Any update on this?

Hi Brian Lam,

You can set the RadGridView theme earlier as setting it in the Loaded event is a bit late.
See the code bellow.

public MainPage()
        {

            InitializeComponent();

            _gridView = new RadGridView()
            {
                ItemsSource = Player.GetPlayers()
            };

            StyleManager.SetTheme(_gridView, new Office_BlueTheme());

            _window = new RadWindow()
            {
                Content = _gridView
            };
            _window.Show();
        }

Hi Vera,

Setting the theme earlier won't work for my application because we have a user preference that isn't loaded until later in the control's lifecycle which tells us what theme to use.

Hello Brian Lam,

 We have investigated this scenario and it seems that this is bug from our side. I have logged this in our PITS system where you can track its progress. The fix will be included in our next internal build (next Monday).

Please excuse us for the inconvenience caused.

P.S. I have updated your telerik points accordingly.

Hello Rachana,

RadGridView does not offer such functionality out-of-the-box. ( dragging groups ).
