Get the height/width of Window WPF

Mark Devid 10817 30-Jan-2014

I have the following code

<Window x:Class="Netspot.DigitalSignage.Client.MainWindow"
       
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
       
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
       
Title="MainWindow" WindowStyle="SingleBorderWindow" 
       
WindowStartupLocation="CenterScreen"
       
WindowState="Normal" Closing="Window_Closing">

Any attempt to get the height / width return NaN or 0.0

Can anyone tell me a way of getting it ?

These 2 methods don't work

//Method1

var h = ((System.Windows.Controls.Panel)Application.Current.MainWindow.Content).ActualHeight;
var w =
((System.Windows.Controls.Panel)Application.Current.MainWindow.Content).ActualWidth;

//Method2

double dWidth = -1;
double dHeight = -1;
FrameworkElement pnlClient = this.Content as
FrameworkElement;
if (pnlClient != null)
{
     dWidth =
pnlClient.ActualWidth;
     dHeight =
pnlClient.ActualWidth;
}

The application will not be running full screen.

Hi Mark,

You can get the width and height that the window was meant to be in the constructor after InitializeComponent has been run, they won't return NaN then, the actual height and width will have to wait until the window has been displayed.

When WindowState == Normal You can do this one from Width /
Height after IntializeComponent().
When WindowState == Maximized You could get the screen
resolution for this one with
System.Windows.SystemParameters.PrimaryScreenHeight;
System.Windows.SystemParameters.PrimaryScreenWidth;
