Telerik Web Release R3 2020

It’s officially Telerik R3 2020 time and we are happy to share all the new components, features, and extensions that Telerik UI for Blazor has shipped over the last four months!

Telerik UI for Blazor just reached a new milestone of 50+ truly native Blazor components that are feature-rich and easy to customize, and supported by extensive developer resources including new online technical training on Blazor and Telerik UI for Blazor!

Following the earlier announced Editor, TreeList, Stock Chart and ContextMenu components, plus multiple Grid and Chart features, with the current 2.17 release we ship three new components—TileLayout, Loader and Switch, many new features like Grid Search and Column Menu, Visual Studio Dashboard Project Template, Linux installer, and more!

As always, we listened to your feedback and included in the release many of the most voted items. Read ahead and see the details of what’s new in Telerik UI for Blazor!

New Blazor TileLayout Component

TileLayout Overview

The new TileLayout is a container UI component consisting of tiles, where plain content and various other Blazor components can be added, such as Grid, Charts, ListView, or components from your app. The TileLayout allows the end users to reorganize and resize the contained tiles inside of it in order to create a layout that best suits their needs. The TileLayout is a great match for Blazor apps that need to provide a flexible and customizable layout and especially dashboard-like applications.

In this code sample you can see how easy it is to add the TileLayout tag and generate a tiled layout:

        <TileLayoutItem HeaderText="Tile 1"></TileLayoutItem>
        <TileLayoutItem HeaderText="Tile 2"></TileLayoutItem>

In essence, the TileLayout component is a two-dimensional grid-based sandbox surface that enables you to display content in tiles. The dimensions are easily configurable through the following properties: Width, Height, Columns, ColumnWidth, RowHeight, RowSpacing and ColumnSpacing as shown in the example below (you don’t have to set them all, the Columns is the main setting):

<TelerikTileLayout Class="CustomClass"
        <TileLayoutItem HeaderText="Tile 1"></TileLayoutItem>
        <TileLayoutItem HeaderText="Tile 2"></TileLayoutItem>

TileLayout Items

Each tile layout item has configurable dimensions (ColSpan and RowSpan), body content, specified through the <Content> tag, header text and header template that cover both simple cases with plain text, and more advanced with components in it.

        <TileLayoutItem Class="CustomItemClass"
                         HeaderText="Item Header">
                <p>Item content</p>
                <p>Item header template</p>

TileLayout Items Resizing

The Tile Layout component allows resizing of its items and can be turned on by its Resizable parameter. Resizing of each item can be done effortlessly by dragging its right-hand side, bottom, or bottom-right-hand corner, which will update its RowSpan or ColSpan respectively.

TileLayout Items Reordering

Along with the resizing of tile items, the component will also allow their reordering via its Reorderable parameter. When reordering is enabled, the user can drag each tile header to reorder the items.

TileLayout State Management

For scenarios when users need to re-shape a layout and be able to continue to use it later, we implemented state management mechanism for the TileLayout. As tile layout items can be moved around and resized to fit users’ preferences, their respective RowSpan, ColSpan and Order parameter values change. By using the exposed GetState() and SetState(state) methods you can save and load TileLayout items order and dimensions.

TileLayout Events

The component currently exposes two events, that let you further control the business logic when items are resized or reordered (for example, to save the current state):

  • OnResize - raised after an item is resized
  • OnReorder - raised after an item is reordered

New Blazor Loader Component

Loader Component Overview

The Loader UI component is essential in every use case where you need to indicate to users in your Blazor app that a process is in progress. Example of such operations can be loading data, submitting a form or performing a large volume of updates. The Loader provides multiple built-in options for configuring its animation, size and colors.

Telerik UI for Blazor Loader Component 

To add the Telerik UI for Blazor Loader component, simply add the TelerikLoader tag as shown in the code snipped below:

<TelerikLoader Class="loader-indicator"></TelerikLoader>

Loader Component Customization

The Loader component comes in different flavors, shapes and sizes. The Type property lets you set one of the available options: Pulsing (default), InfiniteSpinner and ConvergingSpinner.

<TelerikLoader Class="loader-indicator" Type="LoaderType. InfiniteSpinner"></TelerikLoader>

Using the ThemeColor property of the Telerik Loader component for Blazor, you can easily set its color to one of the predefined colors from the Theme Builder.

<TelerikLoader Class="loader-indicator" Type="LoaderType.Pulsing" ThemeColor="@ThemeColors.Success"></TelerikLoader>

In addition to the colors, you can also adjust the Loader size, so that it fits your app scenario. The possible out-of-the box Loader sizes include: small, medium and large.

<TelerikLoader Class="loader-indicator" Type="LoaderType. InfiniteSpinner" Size="LoaderSize.Large"></TelerikLoader>

Loader Component Integration

The Loader can be easily integrated with other Blazor UI components to indicate that an operation is executing. Check out an example on how to integrate a Loader indicator with a Button component.

New Blazor Switch Component

Switch Overview

The Switch UI component allows the user toggle between checked and unchecked states. Originally coming from performing a toggle of states on mobile devices, it has turned to a standard in all types of application. The component comes with configurations for its labels (for both on and off states), events and built-in keyboard navigation and localization.

Telerik UI for Blazor Switch Component

Telerik UI for Blazor Switch Component

To add the Telerik Switch in your Blazor apps, add the TelerikSwitch tag and provide a value using one-way data binding (Value property) or two-way data binding (@bind-Value property) as shown in the code sample below:

<TelerikSwitch @bind-Value="@isSelected"/>
@code {
    private bool isSelected { get; set; }

Switch Labels and Features

You can easily set custom Switch labels for its On and Off states with its OnLabel and OffLabel properties, as shown in the code snippet below:

<TelerikSwitch @bind-Value="@isSelected" OnLabel="Yes" OffLabel="Nope" />
@code {
    private bool isSelected { get; set; }

The Switch component additionally offers features that let you easily customize it such as: Class (CSS class), Enabled, TabIndex and Width. Like the rest of Telerik UI for Blazor components, the Switch supports and integrates seamlessly into Blazor's Forms and Validation infrastructure.

Switch Component Events

To help you handle business logic in your Blazor apps, a couple of events are exposed for the Switch component:

  • ValueChanged -fires every time the Value parameter changes (two-way binding)
  • OnChange - fires after Value Parameter has changed and the ValueChanged event has fired (one-way binding)

Switch Component Built-In Localization

The Switch component labels can be almost auto-magically translated to any language! Thanks to the built-in localization support in Telerik Blazor, UI components react to the current culture automatically, so you can easily translate UI components messages.

Switch Component Built-In Keyboard Navigation

Telerik UI for Blazor Switch component comes with built-in support for keyboard navigation, so the end users can change focus on the control and invoke actions such as toggle state by just using keystrokes.

New Blazor Grid Features

Grid Column Menu

Simplify the access to common column actions on your Grid data with the new Column Menu feature. Your Blazor app users will have a convenient way to apply sorting, filtering, and toggle the visible and lock states of the columns from a central spot.

Column menu enablement is as simple as adding and setting to true a single Grid property ShowColumnMenu. In addition, you could easily customize the enabled features in the Column Menu through the GridColumnMenuSettings tag.

Grid Search Box

In addition to the current Grid filtering options, we implemented another built-in search option, so users can easily filter only relevant records in the Grid.

To add a search text box to your Grid, simply plug inside its toolbar a GridSearchBox tag. Additionally, you can configure which fields to be searchable and specify DebounceDelay value (delay between the last keystroke and filtering). 

        <GridSearchBox DebounceDelay="200"></GridSearchBox>

Grid Multi-Column Sorting

With the new Grid SortMode property you can enable data sorting based on multiple grid columns. The SortMode accepts two values:

  • Single (default value) - only one sort criteria can be applied to the data
  • Multiple - sorting on multiple columns. Sorting on a column and then sorting another one applies both sort criteria to the data (in the order specified)

Grid Footer Template for Aggregates

You can display aggregate results in the Grid footer template for each data bound column—commonly referred to as Grand Total. In the footer you can show aggregate values of each column, as well as custom content. The footer template will be always visible regardless of the vertical scrolling of the Grid.

Grid Column Visible Property

With the new Grid column Visible property, you can easily programmatically show/hide Grid columns permanently or based on a condition.

In a basic scenario, when a column needs to stay hidden at all times, you simply set the column property Visible to false. However, you can also use the Visible parameter for cases when you need to provide conditional visibility of a column, toggle column visibility or determine whether to show a column based a result from a bool method. Check out more code samples on how to control column visibility in Blazor Grid here.

New Blazor TreeList Features

TreeList Search Box

Enable your users to quickly search and find relevant data rows in the TreeList with the new built-in feature Search Box.

The search feature will add a search text box inside the TreeList toolbar and allow you to configure which columns will be searchable. 

TreeList Column Visible Property

Similarly to the Grid, you can toggle column visibility with the TreeList component using the new column Visible property.

TreeList Multi-Column Sorting

The TreeList can now be sorted based on multiple criteria. With the new SortMode property you can enable data sorting based on single (SortMode="@SortMode.Single") or multiple tree list columns (SortMode="@SortMode.Multiple").
