As of the 2022 R1 SP2 release the Shape configuration option of the Button component is no longer available. The Button height is determined by the specified Size and font-size, while the width depends on the Size, font-size, and text length.

Telerik UI for ASP.NET MVC R1 2022 SP1


As of the 2022 R1 SP1 release the Scheduler exposes a modified keyboard navigation behavior. The main reason behind the change is to make the widget a single Tab stop element on the page. This would allow easier navigation to and away from the Scheduler. Further details on the new keyboard navigation behavior could be found on the Keyboard Navigation demo.

As of the 2022 R1 release the type attribute of the Button is set to button by default. Previously, the Button rendered a <button> element without an explicitly set type. The main reason behind this change is to ensure the Button behaves as the Kendo UI for jQuery Button widget. As a result of this change, a Button with a default configuration nested in a form does not submit the form. If you want the Button to submit the form, set its type to submit in the HtmlAttributes configuration, as demonstrated in the example below.

    .HtmlAttributes(new { type = "submit" })
