Question

I have a menu item which has children menu items. When one of the menu items clicked, an event will be fired and do something according to the index of clicked menu item. I have seen such applications but in those cases name of menu item was criterion not index. I want something like this:

private void MI_Click (object sender, RoutedEventArgs e)
{
    MenuItem mnu = (MenuItem)e.OriginalSource;

    switch (mnu.Items.Index) // I know there is no such thing
    {
        case 0: {// do something}
        case 1: {// do something}
        // and so on
    }
}

Answer 1

You could try something like this:

 <MenuItem Header="_Menu">
     <MenuItem Header="Menu1" Click="MenuItem_Click" Tag="1" />
     <MenuItem Header="Menu2" Click="MenuItem_Click" Tag="2" />
     <MenuItem Header="Menu3" Click="MenuItem_Click" Tag="3" />
 </MenuItem>

And in code:

 private void MenuItem_Click(object sender, RoutedEventArgs e)
    {
        MenuItem mi = sender as MenuItem;
        if (mi != null)
        {
            int tag;
            int.TryParse(mi.Tag.ToString(), out tag);
            switch (tag)
            {
                case 1:
                    break;
                case 2:
                    break;
                case 3:
                    break;
            }
        }
    }

EDIT:

To change the Tag of already created MenuItems you could use this:

        int poz = 10;
        foreach (MenuItem menuItem in mi.Items)
        {
            menuItem.Tag = poz++;
        }

where mi is the name of the parent Menu
