Usage
The MessageBox mimics the behavior of the System.Windows.MessageBox closely. You use similar syntax to create and show a message box.
MessageBoxResult result = Microsoft.Windows.Controls.MessageBox.Show("Hello world!", "Extended WPF ToolKit MessageBox", MessageBoxButton.OK, MessageBoxImage.Question);
MessageBoxResult result = Microsoft.Windows.Controls.MessageBox.Show("Hello world!", "Extended WPF ToolKit MessageBox", MessageBoxButton.OK);
MessageBoxResult result = Microsoft.Windows.Controls.MessageBox.Show("Hello world!", "Extended WPF ToolKit MessageBox");
MessageBoxResult result = Microsoft.Windows.Controls.MessageBox.Show("Hello world!");
Style Guide
You can style the MessageBox to fit the theme of your application by using a few of the MessageBox's properties. The following image depicts what properties modify which parts of the MessageBox control.

|---|
| CancelButtonContent | Sets the content of the Cancel button |
| Caption | Gets or sets the caption of the message box. |

ExampleYou can style all instances of your MessageBox control by placing the style definition markup inside your App.xaml file under the resources section. To create the following ugly style requires the following markup.
