How to determine the screen width/height using C#

Question

I want to set the width & height of a Window dynamically based on the user screens maximum width/height. How can I determine this programmatically?

Answer 1

You can use the SizeChanged event

SizeChanged="MyWindow_SizeChanged"

Then in your event handler,

private void Window_SizeChanged(object sender, SizeChangedEventArgs e)
{
    if (this.MinWidth > 0 && this.MinHeight > 0)
    {
        double heightScaleFactor = e.NewSize.Height / this.MinHeight;
        double widthScaleFactor = e.NewSize.Width / this.MinWidth;            
        mainGrid.LayoutTransform = new ScaleTransform(heightScaleFactor, widthScaleFactor);
    }
}

where MainGrid is a container for all the contents in MyWindow.
