Title Body

I want to bind a list of KeyValuePair to a list of MenuItems. I thought I should use MenuIten.HeaderTemplate, but it didn't work. I only got blank headers. <MenuItem Header="Template" ItemsSource="{Binding Path=Samples}"> <MenuItem.ItemTemplate> <DataTemplate> <MenuItem> <MenuItem.HeaderTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Key}" FontWeight="Bold"/> <TextBlock Text="{Binding Path=Value}" FontStyle="Italic" Margin="5,0,0,0"/> </StackPanel> </DataTemplate> </MenuItem.HeaderTemplate> </MenuItem> </DataTemplate> </MenuItem.ItemTemplate> </MenuItem> Then I replaced MenuItem.HeaderTemplate with MenuItem.Header, it worked. <MenuItem Header="Template" ItemsSource="{Binding Path=Samples}"> <MenuItem.ItemTemplate> <DataTemplate> <MenuItem> <MenuItem.Header> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Key}" FontWeight="Bold"/> <TextBlock Text="{Binding Path=Value}" FontStyle="Italic" Margin="2,0,0,0"/> </StackPanel> </MenuItem.Header>
