Common Release Items

Font Icons to SVG Icons

Illustration of Telerik and Kendo UI mascots with SVG

With R2 2023, we performed a change in the default type of icons in Telerik and Kendo UI libraries and components from font to SVG. As part of our ongoing commitment to enhancing product quality, theming mechanisms and Content Security Policy (CSP) compliance, we are gradually transitioning from Font icons to SVG icons.

By eliminating the font icon inline scripts present in themes, we reduced the security risk and improved overall CSP compliance.

Depending on the products you are currently using, you can review details in the listed articles below related to switching to SVG icons or continuing to use font icons if you prefer:

To learn more, visit the dedicated icon blog post, where we have shared the upcoming changes to Kendo UI products’ themes and icon system, along with the expected benefits and timeline of these changes along with preparation resources.

Design System Documentation

One of the standout release items in R2 2023 is the introduction of a design system documentation site, which offers a wealth of resources, design assets and frontend documentation specifically tailored for the Telerik and Kendo UI libraries.

With this initial release, we have included related design and frontend documentation for nearly 20 of the most crucial components. Our ongoing commitment is to continually expand this site, with the ultimate objective of equipping you with all the necessary tools to craft seamless and visually stunning digital experiences and design systems utilizing the power of Telerik and Kendo UI component libraries.

Within the design system documentation site, you will also find documented the initial version of the CSS Utils package, which is a library of HTML classes scoped to a relevant CSS property. It provides the possibility to style a page layout without writing CSS. For example, if you would like to add a border radius, you just add the class .k-rounded-md to the element. This will apply styles for medium border radius.

The CSS utils package is built into our Telerik and Kendo UI themes, so when you install one of our themes, you will get CSS Utils package as well. In the case you want to get only the Utils package for styling a page layout, you can also install it separately. You can learn more about installing the package in the dedicated article.

The package capabilities will continue to grow and we plan to add other CSS Utilities such as adding color system, typography or extending our sizing map.

See a demo of the Kendo UI for jQuery Editor Table Wizard.

Date Editing UX Enhancements

In R2 2023, we introduced multiple enhancements and features related to the date and time UI components for jQuery, namely the DateInput, DatePicker, DateRangePicker, DateTimePicker and TimePicker. In the section below we will review in detail what’s new on a per feature basis.

Auto-Tabbing Improvements
As user preferences and behavior differ when working with dates, we implemented multiple configuration options that allow customizing the behavior of the components when editing and validating datetime values.

Using the new autoSwitchParts option, you can easily enable the auto-tab behavior when editing year, month and date values. You can further specify designated separator, for example slash, dash or column, allowing users to easily tab between the date segments when typing.

Another enhancement is the option enable auto-tabbing by using the mouse wheel. Last but not least, when editing values you can now specify incremental step for increasing/decreasing the date and time values for each of the segments and allow users to adjust them using a mouse wheel.

Auto-Correction of Invalid Dates
Until recently, the default behavior was when a user types in a date like “31/January/2023” and then changes the month to February, the day would automatically switch to February 1. However, we received feedback from you that there are cases when you need to disable this automatic correction so that the user can continue editing the date and manually change the day part of February. Optionally, you can enable auto-switch to show the last day of the next month, i.e., February 28.

The new property autoCorrectParts gives you control over the date auto-correction UX. Its value specifies whether the date parts should be automatically corrected to show a valid date or not. The default value is “true,” meaning that the automatic correction will occur. By setting it to “false,” you will allow users to be able to see “31/Feb/2023” in the input field, but the component value can not be set to this and will be either null or default to the value for the DateTime.

To see all new configuration options of the date editing and validation, check out the dedicated jQuery DateInput Date Editing demo.

DateTimePicker Start and End Values
With the latest release, you can also take advantage of the startTime and endTime configuration options in DateTimePicker components, allowing you specify ranges of allowed values.

See a demo of the new settings for start and end date in the jQuery DateTimePicker.

Scheduler Enhancements

Highlight Real-Time Events
We are excited to introduce a new feature in Kendo UI for jQuery Scheduler that will enhance the clarity and visual emphasis of your appointments. With this latest update, you have the ability to highlight ongoing events by enabling the ongoingEvents.enabled option.

This new feature allows you to easily distinguish events that are currently happening, providing a clear visual representation of ongoing activities within the Scheduler. By enabling the “ongoingEvents.enabled” option, you can ensure that ongoing events stand out prominently, making it easier for users to identify and prioritize their schedule.

Whether you are managing complex project timelines, scheduling team meetings or organizing personal appointments, highlighting ongoing events brings an intuitive and efficient experience to your scheduling tasks.

See an example of highlighting real-time events in Kendo UI for jQuery Scheduler.

Scheduler Custom Toolbar
R2 2023 brings one more new capability in Kendo UI for jQuery Scheduler that enables you to have full control over the Scheduler’s Toolbar. With the latest release, you can now effortlessly customize the Toolbar to perfectly align with your application’s requirements using the toolbar configuration option.

Whether you want to add new buttons, rearrange existing ones or customize their appearance, the toolbar configuration option empowers you to effortlessly achieve your desired layout. Simply define the buttons, their order and associated functionalities, and the Scheduler will reflect your custom Toolbar configuration.

End of Support Announcements

As we continue to evolve and adapt to the ever-changing technology landscape, we want to ensure that we provide you with the most modern and efficient solutions possible.

With that in mind, we have made the decision to deprecate three building parts from the Kendo UI family: Kendo Hybrid, Kendo LESS themes and Kendo components for SharePoint.

LESS Themes Retirement

As announced last year in January 2022, we are confirming that with the current release Kendo UI for jQuery is moving completely to the Sass-based Default, Bootstrap, Material and Fluent themes, and we are sunsetting the LESS-based themes.

With this month’s release, we have officially ended support for LESS themes and they will no longer be included in the distribution of Kendo UI for jQuery, Telerik UI for ASP.NET Core and UI for ASP.NET MVC libraries.

While most of you have migrated to Sass themes, we understand that some are still using LESS themes in their projects. If this is the case, you can continue to use them with your existing packages up until R1 2023 (version 2023.1.117), which is the latest stable version that supports and ships LESS themes. However, if you decide to update to any newer version, please note that starting with the current version onward, our jQuery, ASP.NET Core and ASP.NET MVC libraries will no longer include LESS theme files.

We remain committed to providing a top-notch theming experience for our customers and believe that Sass themes offer superior flexibility and performance. We strongly recommend that customers who are using LESS themes migrate to Sass themes as soon as possible. To assist with this transition, we have provided a detailed guide on why and how to migrate to Sass themes in our documentation.

Kendo Hybrid Retirement

We want to inform you that starting with the R2 2023 release, Kendo UI will no longer ship Hybrid UI components. This means that the current release will be the last one to include Kendo Hybrid in the Kendo UI package.

Our goal has always been to provide you with a comprehensive set of tools and features that cater to your needs. However, as we evaluated the landscape and listened to your feedback, we realized that there is now full parity between components and features offered in Kendo Hybrid and Kendo UI for jQuery. Additionally, we have made significant adaptive and responsive enhancements to the UI for jQuery components.

We understand that technology evolves, and as a result, our customers have expressed a stronger interest in utilizing more modern and current tech stacks such as jQuery, Angular, React and Vue.

We highly recommend planning your migration from Kendo Hybrid to one of the preferred frameworks mentioned above, utilizing the respective libraries: Kendo UI for jQuery, Kendo UI for Angular, KendoReact and Kendo UI for Vue. These libraries offer a wide range of features and components that will meet your application development needs.

If you decide to continue using Kendo Hybrid, you can still do so, but please note that we will no longer provide updates or new features for this component. The latest stable distribution versions of Kendo Hybrid components and themes are available in the R3 2022 release. You can find the necessary package link on our website.

While we will not be actively fixing bugs or addressing issues related to Kendo Hybrid, we will provide one year of support, which includes answering support tickets and assisting with any questions or concerns you may have during this transitional period.

If you encounter any questions or face challenges, please feel free to reach out to our technical support team.

The virtualization feature of the KendoReact Data Grid has undergone significant stability improvements. These improvements are related to the specification of metrics about row size, which enables us to make accurate calculations of rendered rows in the Grid and the scroll position of the content.

Now, the virtualization can work with both all data and sliced data by setting the required field rowHeight. In cases where there are details, another required field is detailRowHeight, and all data must be passed to the Grid. For grouping scenarios, it’s important to pass all data.

To showcase these enhancements, we’ve provided some examples:

Scroll to Index Helper Method
We shipped a further enhancement in the scrolling experience of the KendoReact DataGrid component. In addition to the option to scroll to a specific item, users can now easily check if a selected row is currently visible within the Grid, and, if not, scroll it to the top.

This new functionality is particularly useful in scenarios where users need to quickly locate and interact with a specific row, even when working with a large dataset. With this feature, users can simply select the desired row, and the Grid will automatically check if it is currently visible. If the row is not visible, it will be smoothly scrolled to the top, ensuring that the user can quickly and easily interact with the selected row.

It is worth noting that the feature has been designed to ensure that rows are only scrolled to the top when necessary. Specifically, if 90% of the row’s height is currently visible, it will be considered “visible” and will not be scrolled to the top. Additionally, the rowHeight parameter should be set to match the height of the row according to the design, to ensure that the scrolling behavior is accurate.

See a demo of the KendoReact ScrollIntoView Data Grid feature.

New Configuration Options in Pager Component

The KendoReact Pager UI component can now be configured to show all items in a single page. The feature can be enabled initially, or through the PageSize DropDownList. The PageSize and PageSizeValue option of the pager now accept string “All.”

Enhancements in DropDowns

The data grouping features provide the option to display data in groups inside a component. The grouping can be used and queried by filtering the component. To enable Data Grouping, you need to define the groupField property. The Data Grouping feature is now available for AutoComplete, DropDownList, MultiSelect, ComboBox and MultiColumnComboBox.

ActionSheet Component Improvements

ActionSheet Keyboard Navigation
The KendoReact ActionSheet component now provides out-of-the box keyboard navigation.

See a demo of the available keyboard shortcuts that the KendoReact ActionSheet supports.

ActionSheet Animation
The other enhancement we shipped in the ActionSheet is a smoother animation when the component appears on the screen (enabled via the new animation prop which accepts a Boolean value).

TabStrip Enhancements

The KendoReact TabStrip component now allows you to change the direction of the content when scrolling tabs to right-to-left using its dir property.

See a demo of the RTL support in KendoReact TabStrip component.

Enhancements in FlatColorPicker and ColorGradient

The FlatColorPicker component now includes the following props:

  • defaultValue: This prop allows you to set a default color value, ensuring a consistent starting point for color selection.
  • format: You can now specify the default input format for the gradient input editor. Choose between “rgb,” “hex” or “rgba” to match your preferred color format.
  • opacity: This prop offers more flexibility by providing the option to display the opacity slider. Enable this feature to allow users to select transparency alongside their color choices.

In addition to the prop enhancements, we have also introduced a new method called onChange. This method triggers an event handler whenever the user edits the color value. Use this feature to capture and respond to any changes made by the user.

Moreover, we have made improvements to the ColorGradient component, which is integral to the FlatColorPicker. The ColorGradient component now includes the “format” prop, allowing you to set the default input format in the gradient input editor.
