Universal Windows Platform – Toast Styles

Toast Styles demonstrates how to display the different types of Toast notifications that are possible to be displayed in the Action Centre in Windows 10

Step 1

If not already, follow Setup and Start on how to Install and get Started with Visual Studio 2017 or in Windows 10 choose Start, and then from the Start Menu find and select Visual Studio 2017.


Step 2

Once Visual Studio Community 2017 has started, from the Menu choose File, then New then Project…


Step 3

From New Project choose Visual C# from Installed, Templates then choose Blank App (Universal Windows) and then type in a Name and select a Location and then select Ok to create the Project

Step 4

Then in New Universal Windows Project you need to select the Target Version this should be at least the Windows 10, version 1803 (10.0; Build 17134) which is the April 2018 Update and the Minimum Version to be the same.


The Target Version will control what features your application can use in Windows 10 so by picking the most recent version you’ll be able to take advantage of those features. To make sure you always have the most recent version, in Visual Studio 2017 select Tools Extensions and Updates… then and then see if there are any Updates

Step 5

Once done select from the Menu, Project, then Add New Item…


Step 6

From the Add New Item window select Visual C#, then Code from Installed then select Code File from the list, then type in the Name as Library.cs before selecting Add to add the file to the Project


Step 7

Once in the Code View for Library.cs the following should be entered:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Windows.Data.Xml.Dom;
using Windows.UI.Notifications;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

public class Item
    public string Style { get; set; }
    public string Value { get; set; }

public class Library
    public IEnumerable<string> GetTemplates()
        return Enum.GetValues(typeof(ToastTemplateType))
            .Cast<ToastTemplateType>().Select(s => s.ToString());

    private void UpdateToast(Item item)
        ToastTemplateType template = (ToastTemplateType)Enum.Parse(typeof(ToastTemplateType), item.Style);
        XmlDocument toast = ToastNotificationManager.GetTemplateContent(template);
        XmlNodeList text = toast.GetElementsByTagName("text");
        if (text.Length > 0)
        XmlNodeList image = toast.GetElementsByTagName("image");
        if (image.Length > 0)
            image[0].Attributes.GetNamedItem("src").NodeValue =
        ToastNotification notification = new ToastNotification(toast);

    private async Task<Item> DialogAsync()
        ComboBox template = new ComboBox()
            HorizontalAlignment = HorizontalAlignment.Stretch,
            Margin = new Thickness(5),
            ItemsSource = GetTemplates()
        template.SelectedIndex = 0;
        TextBox text = new TextBox()
            PlaceholderText = "Text",
            Margin = new Thickness(5)
        StackPanel panel = new StackPanel()
            Orientation = Orientation.Vertical
        ContentDialog dialog = new ContentDialog()
            Title = "Toast Styles",
            PrimaryButtonText = "Update",
            CloseButtonText = "Cancel",
            Content = panel
        ContentDialogResult result = await dialog.ShowAsync();
        if (result == ContentDialogResult.Primary)
            return new Item() { Style = (string)template.SelectedItem, Value = text.Text };
        return null;

    public async void Toast()
        Item result = await DialogAsync();
        if (result != null)

There’s a GetTemplates method to get the ToastTemplateType then returns those as an IEnumerable of string. UpdateToast takes a string “style” and “value” – the former is used to get the correct ToastTemplateType based on the style passed in, the latter is used to create a node for the template to represent the value used on the Toast, a ToastNotification is created from this and passed to the Update method of the ToastNotificationManager with CreateToastNotifier. The Dialog has a ComboBox set to the templates using GetTemplates and has a TextBox to enter the value to show – the selected template and value is returned as an Item Class which here is a pair of string values for each of those selections.

The Toast method uses the Dialog method to get the Tuple that contains the selected template and value to use and this is passed to the UpdateToast method from the “result” of the Dialog.

Step 8

In the Solution Explorer select MainPage.xaml


Step 9

From the Menu choose View and then Designer


Step 10

The Design View will be displayed along with the XAML View and in this between the Grid and /Grid elements, enter the following XAML:

<CommandBar VerticalAlignment="Bottom">
	<AppBarButton Icon="Comment" Label="Toast" Click="Toast_Click"/>

The MainPage has a CommandBar with an AppBarButton of Toast which will display the Dialog to then display a Toast Notification in the Action Centre in Windows 10

Step 11

From the Menu choose View and then Code


Step 12

Once in the Code View, below the end of public MainPage() { … } the following Code should be entered:

Library library = new Library();

private void Toast_Click(object sender, RoutedEventArgs e)

Below the MainPage() Method an instance of the Library Class is created, then Toast_Click is used to call the Toast Method from the Library Class.

Step 13

That completes the Universal Windows Platform Application so Save the Project then in Visual Studio select the Local Machine to run the Application


Step 14

After the Application has started running you can then select Toast display a Dialog where you select Style from the ComboBox and Text.


Step 15

The Toast will be displayed in Windows 10 in the Action Centre with the Text entered.


Step 16

To Exit the Application select the Close button in the top right of the Application


Toast Styles shows how you can use the built-in templates for creating toast notifications in different ways, there are more options in some of the templates to product more complex layouts and this example is just the start of showing how flexable toast notifications can be and how easy it is to update them, makes a great feature of an application that needs to show something with a toast in a variety of different ways.
