The Blazor TreeGrid now allows users to rearrange rows along with the detail template row using the drag-and-drop functionality.

DateOnly and TimeOnly values

These features allow users to bind and manage date and time-only values quickly. Users can perform various data operations such as sorting, filtering, searching, and CRUD (create, read, update, delete). To simplify things, built-in DatePicker and TimePicker editor components are rendered for editing and filtering purposes.

Dropdown components with virtual scrolling using the keyboard

The Blazor Dropdown List, ComboBox, and AutoComplete components support virtual scrolling through the keyboard keys. This provides an improved user experience when these components are rendered with large data sets. This feature allows users to navigate the list using their keyboard, making finding and selecting items faster and more efficient.

Note: Check out the Blazor Diagram component scroll settings demo for more details.

Tooltip for symbols

There’s new tooltip support for symbols in the symbol palette. Now, users can conveniently provide additional information or descriptions for each symbol, improving the overall usability and clarity of the symbol palette.

Word Processor (document editor)

From the 2023 Volume 2 release onward, you can enjoy the following features in the Blazor Word Processor.

Alternate text for images

You can now add alternative text (alt text) for images in a text document. Alt text is important for accessibility because it enables all users to understand the content of a document. When someone who uses a screen reader or other assistive technology comes across an image in a document, they will hear the alt text describing the image. Without alt text, they will only know they’ve reached an image without knowing what the image shows.

Link to previous header or footer

This feature allows users to link or unlink the header and footer of the previous section to the current section in a Word document. This can be useful if you want to create a consistent look across your document or if you want to create different headers and footers for each section in the document.

Character spacing and scaling

Character spacing and scaling are two different ways to customize the appearance of text in a Word document. Character spacing refers to the space between individual characters, while scaling refers to the characters’ size. You can increase the character spacing between the letters of a word to make it stand out. You can scale it up to make it easier to read or scale it down to save space.

File Manager

The new features added to the Blazor File Manager are as follows.

Virtual scrolling

The virtual scrolling feature supports UI virtualization for detailed, large-icon views in the Blazor File Manager control. This feature improves performance on the view port’s initial loading of files and folders. The remaining files and folders will be loaded dynamically when the user scrolls through them. Users can load a huge volume of files and folders without any performance issues. Scrolling can also be done with the keyboard.

You can enable this feature by setting the EnableVirtualization property to true.

Toolbar customization

The File Manager allows users to customize the toolbar items directly with icons, text, and a tooltip. The ToolbarItems property and provided template support facilitate the customization of the items in the File Manager. You can now directly add custom toolbar items using the FileManagerCustomToolbarItems tag.

WASM performance enhancement

The PreventRender method in WASM avoids unnecessary re-rendering of the File Manager component. This method internally overrides the ShouldRender method of the File Manager to prevent unnecessary re-rendering.

Gantt Chart

Resource view

The new resource view in the Blazor Gantt Chart is used to display the tasks that are hierarchically assigned to each resource. Resources are displayed as parents, and all the tasks assigned to each resource are displayed as its child records. This feature can be enabled by setting the ViewType to ResourceView.

DateOnly and TimeOnly columns

These column types allow users to bind and manage date- and time-only values easily. Users can perform various data operations such as sorting, filtering, searching, and CRUD (create, read, update, delete). To simplify things, built-in DatePicker and TimePicker editor components are also rendered for editing and filtering purposes.
