Just a month after the R2 2020 release of Telerik UI for ASP.NET Core we are happy to share another update that includes two new components—Wizard and Pager— as well as a new Visual Studio Dashboard project template, compatibility with .NET 5 preview 5 and many new enhancements. Read on and see the highlights in the latest release of Telerik UI for ASP.NET Core!

Compatibility with .NET 5.0 Preview Versions

We continue with our efforts to stay current with all updates by Microsoft in the preview versions of .NET 5.0 until its official release later this year in November. We are happy to share that Telerik UI for ASP.NET Core latest release is compatible with .NET 5.0 preview 5.

New UI for ASP.NET Core Components

New UI for ASP.NET Core Wizard Component

Wizard Component Overview

The new Telerik UI for ASP.NET Core Wizard lets you easily break up long processes into multiple steps and simplify user input tasks by exposing to them just one form at a time. Each Wizard step can have its own content (form or other HTML), comes with built-in form validation (via Form component integration) for the input data and a progress indicator showing the number of steps left towards achieving their final goal for the process.

Wizard Component Initialization HTML and TAG Helpers

To add the Wizard in your ASP.NET Core applications, simply initialize it by giving it a name and adding the needed number of steps and content, as shown in the code sample below:

        .Steps(s=> {
            s.Add().Content("Initial Step");
            s.Add().Content("Second Step");
            s.Add().Content("Final Step");

For those of you who prefer using TAG helpers over HTML helpers, you can directly plug the <kendo-wizard> and <wizard-steps> tags to configure your Wizard component.

Wizard Component Form Integration

The Telerik UI for ASP.NET Core Wizard provides simple, yet powerful integration with the Telerik UI for ASP.NET Core Form component.

Each step of the Wizard can accept a .Form() configuration method which defines many out-of-the box options (as they are available in the Form control itself). This gives you the benefit of having all the functionality available in the stand-alone Form component within the Wizard.

A partial example on how to integrate Form component can be found in the code section below (for more details, check out the Wizard Form demo).

        .Events(ev => ev.Done("onDone"))
        .Steps(s =>
            .Form(f => f
                .Validatable(v =>
                    v.ValidationSummary(vs => vs.Enable(false));
                .FormData(new { Username = "johny", Email = "", Password = "pass123", DateOfBirth = String.Format("{0:ddd, dd MMM yyyy}", DateTime.Now)})
                .Items(items =>
                    items.Add().Field("Username").Label(label => label.Text("Username:"));
                    items.Add().Field("Email").Label(label => label.Text("Email:"));
                    items.Add().Field("Password").Label(label => label.Text("Password:")).InputHtmlAttributes(new { @type = "password" }).Hint("Hint: enter alphanumeric characters only.");
                    items.Add().Field("DateOfBirth").Label(label => label.Text("DateOfBirth:").Optional(true));

In order to facilitate the scenarios where Forms are integrated within the Wizard, the Telerik UI for ASP.NET Core Wizard can be initialized either from a <form> element or a <div> element. The configuration is set via the .Tag() configuration option.

        .Steps(s=> {…}

Wizard Component Loading Content

The Wizard lets you load step content in multiple ways:

  1. Using the built-in support for asynchronously loading content from remote URLs via the ContentUrl configuration option (loading data with AJAX)
  2. Loading Local Content via the Built-in Form Configuration
  3. Loading Local HTML Content

Wizard Component Layout

You can configure the rendering of the Wizard layout using the ContentPosition option to one of the three: a Stepper in a horizontal orientation above the content of the Wizard, vertical left or vertical right side of the Wizard step content.

        .Steps(s=> {…}

Wizard Component Accessibility and Keyboard Navigation

The Wizard has built-in Keyboard Navigation that will allow easy navigation and interaction with the steps and inputs of the component using keyboard. It also comes with out-of-the box support for accessibility standards such as WCAG, Section 508 and WAI-ARIA attributes, that let users with disabilities use the Telerik Wizard with ease.

New UI for ASP.NET Core Pager Component

Pager Component Overview

The Telerik UI for ASP.NET Core Pager is a responsive standalone UI component which enables the splitting of content and its visualization into pages. The Pager component allows integration with other data-bound UI components that do not have built-in paging such as the ListView, and you can use it for paging your data in templates too!

Pager HTML Helper or TAG Helper

To add the Pager to your applications using an HTML helper you need to define a standalone data source and pass it by name to the Pager and to the data-bound control that will use it, as shown in the example below:

     .Ajax(t=>t.Read(read => read.Action("People_Read", "Pager")).PageSize(20))

Alternatively, you can use the handy TAG helper option:

<kendo-datasource name="dataSource1" type="DataSourceTagHelperType.Ajax" server-operation="false">
        <read url="@Url.Action("TagHelper_Products_Read", "DataSource")" />
<kendo-pager name="pager1" refresh="true" datasource-id="dataSource1" page-sizes="true">

Pager Configuration and Settings

The Pager component can be configured to show a specific number of buttons that will be shown in a numeric page, or accept user input via its type setting:

.Numeric(true) //default

Additionally, you have control over which built-in Pager elements will be rendered:

  • PageSizes() - renders the dropdown that allows the user to change the page size
  • Refresh() - renders a refresh button
  • PreviousNext() - toggles the visibility of buttons for navigating to the first, last, previous and next pages
  • Info() - toggles the visibility of the current pager information

Pager Built-In Localization

The UI for ASP.NET Core Pager component has built-in localization support, which makes it easy to translate messages such as: the text of the tooltips for its page and navigation links, information text and labels to any language that your app may require.
