Notification in Razor Pages

Updated on Dec 10, 2025

This article describes how to seamlessly integrate and configure the Telerik UI Notification for ASP.NET Core in Razor Pages applications.

Referencing Handler Methods in Razor Pages

Razor Pages is an alternative to the MVC pattern that makes page-focused coding easier and more productive. This approach consists of a cshtml file and a cshtml.cs file (by convention, the two files have the same name).

The cshtml.cs file, known as the PageModel, contains handler methods that respond to HTTP requests. These methods are prefixed with On followed by the HTTP verb (for example, OnGet, OnPost, OnPostRead, OnPostCreate).

Handler methods declared in a PageModel can be referenced from any Razor Page using one of the following URL patterns:

Using Url.Page()
C#
```
Url.Page("PageName", "HandlerName")
// OR
Url.Page("/FolderName/PageName", "HandlerName")
```
For example, Url.Page("Index", "Read") references the OnPostRead or OnGetRead handler method in the Index.cshtml.cs file.
Using a query string
C#
```
Url("/PathToPage?handler=HandlerName")
```
For example, Url("/Index?handler=Read") references the OnPostRead or OnGetRead handler method in the Index page.

For more information on Razor Pages architecture and concepts, refer to the official Microsoft documentation.

Showing Notification on Post Request

The following example demonstrates how to display a Notification with data retrieved from a PageModel handler method through an AJAX POST request.

Razor
@page
@model NotificationIndexModel

@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf
@Html.AntiForgeryToken()	

<button id="showNotification" class="k-button">Show notification</button>

@(Html.Kendo().Notification()
	.Name("notification")
	.Width("20em")
	.Templates(t =>
	{
		t.Add().Type("info")
			.ClientTemplate("<div>TEXT: <span class='custom-style'>#: text #</span> </div> <div>TIME: <span class='custom-style'>#: time #</span> </div>");
	})
)
Razor
@page
@model NotificationIndexModel

@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf
@Html.AntiForgeryToken()	

<button id="showNotification" class="k-button">Show notification</button>

<kendo-notification name="notification" width="200">
    <templates>
        <notification-template type="info"
		template="<div>TEXT: <span class='custom-style'>#: text #</span> </div> <div>TIME: <span class='custom-style'>#: time #</span> </div>">
        </notification-template>
    </templates>
</kendo-notification>
JS
<script>
	$(document).ready(function () {
		$("#showNotification").click(function () {
			$.ajax({
				url: '/NotificationIndex?handler=Read',
				type: "POST",
				contentType: "application/json; charset=utf-8",
				headers: {
					RequestVerificationToken: $('input:hidden[name="__RequestVerificationToken"]').val()
				},
				dataType: "json",
				success: function (response) {
					// Show notification based on the returned data from the server                    
					var notification = $("#notification").getKendoNotification();
					notification.show({
						text: response.Text,
						time: kendo.toString(new Date(response.Time), "dd MMMM yy hh:mm tt")
					}, "info");
				}
			});
		});
	});
</script>
C#
public class NotificationIndexModel : PageModel
{
	public JsonResult OnPostRead()
    {
        NotificationModel model = new NotificationModel()
        {
            Text = "Notification Text",
            Time = DateTime.Now
        };
        return new JsonResult(model);
    }
}
