WPF Toast Notifications

This is a project which provides simple, beautiful toast notifications for WPF desktop applications.

Getting Started

Here's how to add this project to your solution:

1. Download and extract the project.
2. Add the .csproj to your solution.
3. Rebuild the project.

Alternatively, you could build the project on it's own and add a reference to the output DLL in the bin folder from your solution.

Code Examples

To create a simple toast, use the following code:

using PeanutButter.Toast;

...

string title = "Hello World!";
string message = "This is a test";
ToastTypes type = ToastTypes.Info;

Toaster toaster = new Toaster();
toaster.Show(title, message, type);

Toasting an Exception

You can display a toast notification to display the Message inside an Exception:

catch (Exception ex)
{
    toaster.Show(ex);
}

Or

catch (Exception ex)
{
    toaster.Show("Something Failed!", ex);
}

Toast Within Bounds

If you want to display a toast inside the bounds of the window, you can pass in the window location to the parentContainer parameter:

Rect windowBounds = new Rect(
    this.Left,
    this.Top,
    this.Width,
    this.Height);

toaster.Show(title, message, type, windowBounds);

Persistent Toasts

Sometimes you might want your toast to stick around until the user manually closes it. You can pass in true into the isPersistent parameter:

toaster.Show(title, message, type, isPersistent: true);

Display Toasts For Longer

Toasts will be displayed for 5 seconds by default, if you want to extend this period you can pass in a TimeSpan into the displayTime parameter:

//10 seconds
TimeSpan displayTime = new TimeSpan(10000);

toaster.Show(title, message, type, displayTime);

Changing The Toast Template

The toast can be restyled using the standard WPF style overriding:

xmlns:toast="clr-namespace:PeanutButter.Toast;assembly=PeanutButter.Toast"

...

<Style TargetType="{x:Type toast:ToastNotification}" BasedOn="{StaticResource {x:Type toast:ToastNotification}}">
   <Setter Property="FontFamily" Value="Consolas"/>
   ...
</Style>

Here is the result:

When overriding the Template, there is a named Button called PART_DismissButton. This is optional however if present, the Click event will automatically be registered.

Mocking and Unit Testing

For unit testing, I recommend that you first ensure that any Toaster objects are added to your classes using dependency injection, this will prevent any real toasts from being displayed inside unit tests.

private IToaster _toaster;

public MyClass(IToaster toaster)
{
    _toaster = toaster;   
}

The method of dependency injection is up to you, however this will allow you to make use of the interface IToaster which can be mocked. For example using the NSubstitute framework.

IToaster toaster = Substitute.For<IToaster>();
