 In IE context menu is working fine, but in FF it is working on every other click.

Has anyone found solution for it?

 Can you share the code that you wrote for it? so we can try replicating this in our machine and see any solution

 In the constructor of the page I have added this segment of the code:

 public partial class GroupsAndAreasMainPage : Telvent.SilverlightExt.MVVM.View
{

        public GroupsAndAreasMainPage()
        {
        InitializeComponent();
        DataContext = GroupsAndAreasMainViewModel.GetInstance();
            InitView();

        HtmlPage.Document.AttachEvent("oncontextmenu", ((GroupsAndAreasMainViewModel)DataContext).OnContextMenu);
    }
}

  In ViewModel class I have a ContextMenu method like this:

 

public class GroupsAndAreasMainViewModel : ViewModel

    {
        public GroupsAndAreasMainViewModel()
        {
        }      
        
        public void OnContextMenu(object sender, HtmlEventArgs e)
        {
            
                Point clickPoint = new Point(e.OffsetX, e.OffsetY);
                List hittedElements = VisualTreeHelper.FindElementsInHostCoordinates(clickPoint, MainViewModel.GetInstance().LayoutRoot) as List;
                if (hittedElements.Count > 0)
                {
                    UIElement currentElement = null;

                    foreach (UIElement element in hittedElements)
                    {
                        currentElement = element;
                        if ((element.GetType().Name == "TreeViewItem" &&
                            ((((TreeViewItem)element).GetItem() is GATreeViewItem) || (((TreeViewItem)element).GetItem() is TreeViewItem)))
                            || (element.GetType().Name == "DataGridRow"))
                        {
                            break;
                        }
                    }

                    PopupItems.Clear();
                    GeneralTransform transform = Application.Current.RootVisual.TransformToVisual(LayoutRoot);
                    Point absolutePoint = new Point(e.OffsetX, e.OffsetY);
                    Point relativePoint = transform.Transform(absolutePoint);

                    if (currentElement != null)
                    {
                        if (currentElement.GetType().Name == "TreeViewItem")
                        {
                            PopupItems.Add(new PopupItem() { Name = "Add Area" });
                            PopupItems.Add(new PopupItem() { Name = "Edit Area" });
                            PopupItems.Add(new PopupItem() { Name = "Delete Area" });
                            
                            GAPagePopup.HorizontalOffset = relativePoint.X;
                            GAPagePopup.VerticalOffset = relativePoint.Y;
                            GAPagePopup.IsOpen = true;
                        }   
                    }
                }
            e.PreventDefault();
            e.StopPropagation();
        }
    }
}
