Load layout Catastophy error when bind Menu into GridView

[Gaurang]

Hi,

I am using Docking control in My Dashboard. There are 5 different grid and scheduler etc...
Now I am binding menu into all diffrenet GridView at runtime. It done perfectly without any error.

But my problem is When I LoadLayout and then binde Menu into GridView it does not show any menu into GridView and does not show me any error. Lay out restore perfectly.

Now If I bind Menu into GridView first and then load layout (LoadLayout) it give me error.
Error HRESULT E_FAIL has been returned from a call to a COM component.
and Lay out does not restore. Some time it does not give me the error but if I try to dock any girdview or item it gives me Catastrophy error.


Binding Menu

here gv = GridView
            gv.Columns.AddRange(new CrmActivityController().GridViewColumns);
            gv.Columns.Remove(gvCalls.Columns[CurrentLanguage.CrmActivity.LBLTYPE.ToString()]);
            GridViewHeaderMenu.SetIsEnabled(gv, true);
            gv.Columns.Remove(gvCalls.Columns["DefaultContact.Account"]);
            gv.Columns.Remove(gvCalls.Columns["DefaultContact.FullName"]);

public class GridViewHeaderMenu
    {
        public static readonly DependencyProperty IsEnabledProperty
           = DependencyProperty.RegisterAttached("IsEnabled", typeof(bool), typeof(CrmGridViewHeaderMenu),
                                                 new System.Windows.PropertyMetadata(new PropertyChangedCallback(OnIsEnabledPropertyChanged)));

        private GridView grid = null;

        public GridViewHeaderMenu(GridView grid)
        {
            this.grid = grid;
        }

                    menu.Attach();
                }
            }
        }

        private void RowLoaded(object sender, RowLoadedEventArgs e)

            {
                InitializeMenus((GridViewHeaderRow) e.Row);
            }
        }

        private void InitializeMenus(GridViewHeaderRow row)
        {
                RadMenuItem item = new RadMenuItem() { Header = "Choose Columns:" };
                contextMenu.Items.Add(item);
                foreach (GridViewColumn column in grid.Columns)
                {
                    RadMenuItem subMenu = new RadMenuItem()
                                              {
                                                  Header = column.Header,
                                                  IsCheckable = true,
                                                  IsChecked = true
                                              };
                    subMenu.SetBinding(RadMenuItem.IsCheckedProperty,
                                       new Binding("IsVisible") { Mode = BindingMode.TwoWay, Source = column });

                    item.Items.Add(subMenu);
                }
                contextMenu.AddHandler(RadMenuItem.ClickEvent, new RoutedEventHandler(OnMenuItemClick));
                RadContextMenu.SetContextMenu(grid, contextMenu);
            }
        }
private void OnMenuItemClick(object sender, RoutedEventArgs e)
        {
}
}
}

I havae post same problem on Menu Forum.

Hi,

I cretaed one sample application to resolved above problem (When I add RadContextMenu into GirdView my docking going to stop and It gives me error [System.Exception: Error HRESULTE_FAIL has been returned from a call to COM component.] if I try to dock any item. Second is, it can not load my layout means restoring layout using LoadLayout method.) and I found that I when I am using GridViewAutoGenerationColumnsEventArgs Events it gives me error. Because I want to add Hyperling in two diffenrent columns at runtime. For that I used below code.

<Grid.Resources>
