Changing the Background of an MDI Parent Form

[jmcilhinney]

Here's some more succinct code that uses extension methods and, therefore, requires .NET 3.5 or later:

private void Form1_Load(object sender, EventArgs e)
{
    // Get a reference to the one and only MdiClient in the Controls collection.
    MdiClient client = this.Controls.OfType<MdiClient>().Single();
 
    // Set properties of the MdiClient here, e.g.
    client.BackgroundImage = Properties.Resources.MdiBackgroundImage;
}
