Async CustomMessageBox on Windows Phone

UPDATE: There’s a new Version with .NET4.5 Support, Code Samples

Hey there,

As you may know, there’s just a limited set of MessageBoxButtons available in Silverlight for WP. However, you can make your own MessageBox in your Silverlight app using the Microsoft.Xna.Framework.GamerServices namespace as explained in this tutorial by Den Delimarsky.

This method uses the old style async, which really sucks, so I decided to go the cool and smart new async way. You need Visual Studio Async CTP and Visual Studio 2010 to do this.

The trick is to wrap the old async methods together with async Tasks, resulting in a Task<int> that shows the custom message box and returns the selected button in just one line:

int result = await CustomMessageBox.ShowAsync(“Dinner time!”, “What do you prefer?”, 0, CustomMessageBoxIcon.Alert, “German”, “Italian”);

Asynchronously and therefore non-UI-thread-blocking, of course Zwinkerndes Smiley

If you’re interested you can have a look at the source: CustomMessageBox.cs

Or get TCD.Controls from NuGet

have fun =)
