I am currently creating a sidebar-like WPF application in C#. When a user starts the application, I would like the window to automatically position it's self to the side of the user's screen. I have tried a few methods and google searches, but have not found any help.
Here's an example of what I'm trying to do:

How can I efficiently go about achieving something like this?
@dknaack
I tried this code:
private void Window_Loaded(object sender, RoutedEventArgs e)
{
this.Left = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Right - this.Width;
this.Top = 0;
this.Height = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height;
}
and got the following errors:
Error 1 The type 'System.Drawing.Size' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. C:\Users\Test\Documents\Expression\Blend 4\Projects\WindBar_Prototype_1\WindBar_Prototype_1\MainWindow.xaml.cs 32 13 WindBar_Prototype_1
and
Error 2 'System.Drawing.Size' does not contain a definition for 'Width' and no extension method 'Width' accepting a first argument of type 'System.Drawing.Size' could be found (are you missing a using directive or an assembly reference?) C:\Users\Test\Documents\Expression\Blend 4\Projects\WindBar_Prototype_1\WindBar_Prototype_1\MainWindow.xaml.cs 32 78 WindBar_Prototype_1
Any help?
Description
You can use Screen from System.Windows.Forms.
So add reference to the System.Windows.Forms.dll and System.Drawing.dll. Then change the Left and Height property in the MainWindow_Loaded method.
Sample
public MainWindow()
{
InitializeComponent();
this.Loaded += new RoutedEventHandler(MainWindow_Loaded);
}
void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
this.Left = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Right - this.Width;
this.Top = 0;
this.Height = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height;
}
More Information
You can do this without referencing win forms assemblies by using SystemParameters. In the code behind for your window XAML:
MainWindow() {
InitializeComponents();
this.Loaded += new RoutedEventHandler(
delegate(object sender, RoutedEventArgs args) {
Width = 300;
Left = SystemParameters.VirtualScreenLeft;
Height = SystemParameters.VirtualScreenHeight;
}
}
SystemParameters documentation
in your xaml :
WindowStartupLocation="Manual"
in the constructor :
Left = System.Windows.SystemParameters.PrimaryScreenWidth - Width
Top=0
public MainWindow()
{
InitializeComponent();
WindowStartupLocation = WindowStartupLocation.Manual;
Left = System.Windows.Forms.SystemInformation.PrimaryMonitorSize.Width - Width;
}
use startPosition property or location property
