Как создать меню в WPF, которое имеет стиль веб-приложения Microsoft
нам было поручено разработать корпоративное приложение в WPF, которое заменит приложение WinForms серого цвета линкора современным внешним видом.
нам нравится внешний вид и ощущение, что веб-приложения Microsoft в настоящее время обладают:
мы могли бы создать эти меню в WPF обычным способом:
<DockPanel>
<Menu DockPanel.Dock="Top">
<MenuItem Header="_File">
<MenuItem Header="_New" />
<MenuItem Header="_Open" />
<MenuItem Header="_Save" />
<Separator />
<MenuItem Header="_Exit" />
</MenuItem>
</Menu>
<TextBox AcceptsReturn="True" />
</DockPanel>
но мы получим что-то, что выглядит как меню Winforms.
Я видел некоторые довольно впечатляющие усилия по стилизации, как этот, но все они, похоже, имеют одинаковую знакомую форму Winforms. Я также видел меню в библиотеках, таких как Mahapps Metro, но они кажутся нам слишком спартанскими.
является ли элемент управления меню WPF достаточно гибким, чтобы быть стилизованным, как показано на рисунке выше, или мы должны пойти другим путем, как создание пользовательского элемента управления меню из панелей стека и списков? Каковы компромиссы?
бонусные баллы (т. е. баунти) будут начислены за xaml / код, который делает именно это.
пример этого стиля меню в действии:

WPF был действительно разработан с возможностью изменения внешнего вида и поведения всех готовых механизмов / элементов управления (кнопки, меню, treeview и т. д.). Так что, в общем, лучше это сделать, чем все переписывать. Например, если вы перепроектируете свое пользовательское меню, вам придется подумать о клавиатуре, автоматизации пользовательского интерфейса и т. д...
Итак, я дал шанс на ваш пример и попытался создать минимальный рабочий образец-чистый XAML - который имитирует VS online menu (я также добавлено изменение цвета фона наведения, которое не по умолчанию в меню WPF).
вот результат и, как вы видите, он выглядит очень похожим:
вот XAML. Я решил использовать шаблон пользовательского элемента управления для каждого MenuItem. Я думаю, что это довольно практично, когда вам нужно действительно настроить каждый элемент.

вы, вероятно, ищете какую-то тему Wpf для начала.
таких как http://brianlagunas.com/free-metro-light-and-dark-themes-for-wpf-and-silverlight-microsoft-controls/ или взгляните на это так ответить: любые бесплатные темы WPF?
тогда вы, вероятно, захотите настроить его еще больше с помощью внешний вид вы ищете.
это меню по умолчанию, но Белый, вы можете изменить цвет фона, шрифт текста, высоту и все остальное, что вы хотите, просто отредактировав этот стиль.

Я бы создал меню с XAML
XAML страницы что-то вроде этого:
<Window.Resources>
<Style TargetType="TextBlock">
<Setter Property="Margin" Value="10" />
<Setter Property="FontSize" Value="15" />
<Setter Property="Foreground" Value="White" />
</Style>
</Window.Resources>
<Grid x:Name="Content">
<Grid >
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<StackPanel Orientation="Horizontal" Background="CornflowerBlue">
<TextBlock Text="Menu1" MouseLeftButtonDown="OnMouseLeftButtonDown" />
<TextBlock Text="Menu2" MouseLeftButtonDown="OnMouseLeftButtonDown" />
<TextBlock Text="Menu3" MouseLeftButtonDown="OnMouseLeftButtonDown" />
</StackPanel>
<Border Grid.Row="1" Background="Bisque"></Border>
</Grid>
</Grid>
и в коде:
private void OnMouseLeftButtonDown(object sender, MouseEventArgs e) {
var textBlock = sender as TextBlock;
if (textBlock == null) return;
var relativePoint = VisualTreeHelper.GetOffset(textBlock);//textBlock.TransformToAncestor(Content).Transform(new Point(0, 0));
//Almost invisible Background - If the user clicks it the menu is hidden
var back = new Border{Background = new SolidColorBrush(Color.FromArgb(1,255,255,255))};
back.MouseLeftButtonDown += (o, args) => {
Content.Children.Remove(back.Tag as UIElement);
Content.Children.Remove(back);
};
Content.Children.Add(back);
//Build menu
var menu = new Border{Background = new SolidColorBrush(Colors.White), Width = 200, Height = 500, BorderBrush = new SolidColorBrush(Colors.Gray), BorderThickness = new Thickness(1), HorizontalAlignment = HorizontalAlignment.Left, VerticalAlignment = VerticalAlignment.Top};
back.Tag = menu;
menu.RenderTransform = new TranslateTransform(relativePoint.X, relativePoint.Y + textBlock.ActualHeight + 5);
//Do some more styling
//Fill Menu here according to the tag of the TextBlock (switch(textBlock.Tag){...} or use a predefined view
Content.Children.Add(menu);
//Hide the Menu on click - TODO Implement logic to hide menu if a MenuItem was clicked...
menu.MouseLeftButtonDown += (o, args) => {
Content.Children.Remove(back.Tag as UIElement);
Content.Children.Remove(back);
};
}
ОК, это очень простой пример и не работает, но я думаю, что вы можете работать на нем...
