How to add menu items to menu control (not contextmenu) in WPF from a database table with Bindings and Observable collections?. I have this menu:

<Menu HorizontalAlignment="Left" Height="27" VerticalAlignment="Top" Width="649">
            <MenuItem Header="_File">
                <MenuItem Header="_Exit" Command="{Binding ExitCommand}"/>
            </MenuItem>
            <MenuItem Header="_MyMenu">
                <MenuItem Header="_SubMenu1" Command="{Binding  SubMenu1Command}" />
                <MenuItem Header="_SubMenu2" Command="{Binding  SubMenu2Command}" />
            </MenuItem>
        </Menu>

<Menu HorizontalAlignment="Left" Height="27" VerticalAlignment="Top" Width="649"
	ItemsSource="{Binding ObservableCollectionMenu}">
            <MenuItem Header="_File">
                <MenuItem Header="_Exit" Command="{Binding ExitCommand}"/>
            </MenuItem>
            <MenuItem Header="_MyMenu">
                <MenuItem Header="{Binding  ObservableCollectionMenu.SubMenuColumn}" 
			Command="{Binding  ObservableCollectionMenu.CommandColumn}" />
            </MenuItem>
        </Menu>

When I run the app the menu must show this when I press the options File and MyMenu:

File | MyMenu
Exit | SubMenu1
| SubMenu2

Both System.Windows.Controls.Menu and System.Windows.Controls.MenuItem have the property Items, System.Windows.Controls.ItemsControl.Items which has the method Add:
http://msdn.microsoft.com/en-us/library/system.windows.controls.menu.aspx[^]
http://msdn.microsoft.com/en-us/library/system.windows.controls.menuitem.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.controls.itemscontrol.items.aspx[^],
.http://msdn.microsoft.com/en-us/library/system.windows.controls.itemcollection.add.aspx[^].

I hope the rest is clear.

You sugest a listbox like menu items, I did this. I need a drop-down menu, I'm working with WPF and MVVM.

For WPF, this is exactly the same thing. All menus available in WPF part of FCL use the same menu item class, System.Windows.Controls.MenuItem.

I don't have a quick solution in XAML. I needed get submenus items from database, according specific profiles, some users had all items others only 2 or 3 items. The unique way is create the menu in XAML with disabled items, pass the menu reference to ViewModel(if is MVVM App) and compare with the ObservableCollection, only the items equals are enabled:

HTML

<menu horizontalalignment="Left" height="27" verticalalignment="Top" width="649" name="menu1">
      <menuitem header="_File">
          <menuitem header="_Exit" command="{Binding ExitCommand}" />
      </menuitem>
      <menuitem header="_MyMenu">
          <menuitem header="_SubMenu1" command="{Binding  Command1}" isenabled="False" />
          <menuitem header="_SubMenu2" command="{Binding  Command2}" isenabled="False" />
      </menuitem>
</menu>

ViewModel:

C#

for (int i = 0; i < ObservableCollectionMenu.Count; i++)
{

    for (int j = 0; j < ((MenuItem)menu1.Items[1]).Items.Count; j++)
    {
         if (((MenuItem)((MenuItem)menu1.Items[1]).Items[j]).Header.ToString().Equals(ObservableCollectionMenu[i].SubMenuColumn))
         {
            ((MenuItem)((MenuItem)menu1.Items[1]).Items[j]).IsEnabled = true;
             break;
         }
    }
}

I think that before the programmers had better support and help from codeproject.
Thanks.
