Make my wpf application Full Screen (Cover taskbar and title bar of window)

Question

I would like to make my application such that it can maximize to full screen means it hide the windows task bar and the title bar as well. And it should triggered by a button.

I am trying to develop the my application window like this.

Add my code snippet below

 <controls:MetroWindow x:Class="EDUI.MainWindow"
            xmlns:controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:local="clr-namespace:EDiscoveryCore;assembly=EDiscoveryCore"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            Title="eDi"  BorderBrush="SkyBlue" BorderThickness="2" Height="999" Width="1071" WindowState="Maximized" x:Name="MainWindows">

Solution 1

Try this:

<Window ShowTitleBar="False" IgnoreTaskbarOnMaximize="True">

Solution 2

You need to set the WindowStyle to none as well as WindowState to Maximized

<Window ...    
 WindowStyle="None"   
 WindowState="Maximized">

Solution 3

You need to set the ResizeMode to NoResize and WindowState to Maximized

  <Window ...    
    ResizeMode="NoResize" WindowState="Maximized">

Solution 4

If the taskbar doesn't disappear, it may help to change the Window visibility before and after changing window style, like this:

    private void MainWindow_StateChanged(object sender, EventArgs e) {
        if (this.WindowState == WindowState.Maximized) {
            // hide the window before changing window style
            this.Visibility = Visibility.Collapsed;
            this.Topmost = true;
            this.WindowStyle = WindowStyle.None;
            this.ResizeMode = ResizeMode.NoResize;
            // re-show the window after changing style
            this.Visibility = Visibility.Visible;
        }
        else {
            this.Topmost = false;
            this.WindowStyle = WindowStyle.SingleBorderWindow;
            this.ResizeMode = ResizeMode.CanResize;
        }
    }

Solution 5

You just need to set the WindowStyle to none:

<Window ...
    WindowStyle="None">

To use IgnoreTaskbarOnMaximize you need to be using MahApps, see mahapps.com

ResizeMode="NoResize" was the missing piece for me with Windows 10 WPF. Thank you @Narek

[T James]

Worked for me also. Thank you!

This also was solution for WPF on windows 10. Without that it works fine on win 7 but not on win 8 and win 10. I am using WindowState="Maximized" WindowStyle="None" ResizeMode="NoResize"

ShowInTaskbar="False"

I already had WindowStyle=None and WindowState=Maximized (in this order!) which worked in Windows 7 and Windows 8.1 without a problem. But as soon as my application opened a dialog window, the taskbar appeared topmost on Windows 10 - and it didn't went away, except when switching to a different window and back to my application. ResizeMode=NoResize solved this!

Is ShowTitleBar a real property? It's giving me an error, and apparently the correct way of hiding the title bar is WindowStyle="None"

[krobelusmeetsyndra]

That did it for me. Thanks a lot!!
