The following help topic lists the data editors and supported event handlers: HTML Attributes and Events. You can also use the new InputCssClass and TextAreaCssClass properties to assign your CSS class to the input/text area of the DevExpress ComboBox, Date Edit, Spin Edit, Text Box, Time Edit, and Memo UI components.
  • Move Focus to an Editor in Code - The Blazor Data Editors include a new 'FocusAsync' method. FocusAsync allows you to focus the input field in code.

  • Popup Position - Use the new HorizontalAlignment and VerticalAlignment properties to position a Popup on screen.

Simply create named areas, assign them to layout items, and place these areas within grid rows in the appropriate/required order.
  • Tabs - Tab Content Render Modes - Use the new DxTabs.RenderMode property to specify how the DevExpress Blazor Tab component loads tab content. Render modes are as follows:
    • Default. Adds tab content to the DOM each time a tab is activated (replaces the content of the previously active tab).
    • All Tabs. Renders all tab content on initial load and persists it within the DOM. This mode should only be used for apps with a few tabs in its layout (as it can increase page load time).
