Examples

The following example shows how to use markup to configure a window to be opened without being activated.

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="WindowShowActivatedSnippets.AWindow"
    ShowActivated="False">

using System.Windows;

namespace WindowShowActivatedSnippets
{
    public partial class AWindow : Window
    {
        public AWindow()
        {
            InitializeComponent();
        }
    }
}


Imports System.Windows

Namespace WindowShowActivatedSnippets
    Partial Public Class AWindow
        Inherits Window
        Public Sub New()
            InitializeComponent()
        End Sub
    End Class
End Namespace

The following example shows how to use code to configure a window to be opened without it being activated.

AWindow window = new AWindow();
window.ShowActivated = false;
window.Show();

Dim window As New AWindow()
window.ShowActivated = False
window.Show()

Remarks

When a window with its ShowActivated property set to false is opened, the window is not activated and its Activated event is not raised until a user manually activates the window by selecting it. After the window is selected, it activates and deactivates normally.

To prevent a window from being activated when it opens, the ShowActivated property must be set to false before the window is shown (by calling Show); setting ShowActivated to false after a window is shown has no effect.

Setting ShowActivated to false on a window that is opened modally, by calling ShowDialog, has no real impact. Although the modal window will not be activated, the modal window will prevent the user from activating any other open application windows.
