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;
}

public static void SetIsEnabled(DependencyObject dependencyObject, bool enabled)
{
dependencyObject.SetValue(IsEnabledProperty, enabled);
}

public void Attach()
{
if (grid != null)
{
grid.RowLoaded += new EventHandler<RowLoadedEventArgs>(RowLoaded);
}
}

private static void OnIsEnabledPropertyChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs e)
{
GridView grid = dependencyObject as GridView;
if (grid != null)
{
if ((bool) e.NewValue)
{
GridViewHeaderMenu menu = new GridViewHeaderMenu(grid);
menu.Attach();
}
}
}

private void RowLoaded(object sender, RowLoadedEventArgs e)
{
if (e.Row is GridViewHeaderRow)
{
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 Docking Forum.
Thanks,
