Make WPF Application Fullscreen (Cover startmenu)

I would like to make my WPF application fullscreen. Right now the start menu prevents it from covering everything and shifts my application up. This is what I have for my MainWindow.xaml code:

<Window x:Class="HTA.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    mc:Ignorable="d" 
    WindowStyle="None" ResizeMode="NoResize"
    WindowStartupLocation="CenterScreen" 
    Width="1024" Height="768">

If you want user to change between WindowStyle.SingleBorderWindow and WindowStyle.None at runtime you can bring this at code behind:

Make application fullscreen:

RootWindow.Visibility = Visibility.Collapsed;
RootWindow.WindowStyle = WindowStyle.None;
RootWindow.ResizeMode = ResizeMode.NoResize;
RootWindow.WindowState = WindowState.Maximized;
RootWindow.Topmost = true;
RootWindow.Visibility = Visibility.Visible;

Return to single border style:

RootWindow.WindowStyle = WindowStyle.SingleBorderWindow;
RootWindow.ResizeMode = ResizeMode.CanResize;
RootWindow.Topmost = false;

Note that without RootWindow.Visibility property your window will not cover start menu, however you can skip this step if you making application fullscreen once at startup.

When you're doing it by code the trick is to call

WindowStyle = WindowStyle.None;

first and then

WindowState = WindowState.Maximized;

to get it to display over the Taskbar.

window.WindowStyle = WindowStyle.None;
window.ResizeMode = ResizeMode.NoResize;
window.Left = 0;
window.Top = 0;
window.Width = SystemParameters.VirtualScreenWidth;
window.Height = SystemParameters.VirtualScreenHeight;
window.Topmost = true;

Works with multiple screens

<Window x:Class="HTA.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    ResizeMode="NoResize"
    WindowStartupLocation="CenterScreen" 
    Width="1024" Height="768"
    WindowState="Maximized" WindowStyle="None">

Window state to Maximized and window style to None

You can also do it at run time as follows :

  • Assign name to the window (x:Name = "HomePage")
  • In constructor just set WindowState property to Maximized as follows

HomePage.WindowState = WindowState.Maximized;

You're probably missing the WindowState="Maximized", try the following:

<Window x:Class="HTA.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525"
    WindowStyle="None" ResizeMode="NoResize"  
    WindowStartupLocation="CenterScreen" WindowState="Maximized">
