Once an item is disabled, it cannot be selected as a value for the component. This is particularly useful for disabling options such as out-of-stock products or inactive account types. To configure the disabled item columns, use the DropDownListFieldSettings.Disabled property.

MultiSelect Dropdown

Virtual scrolling

The Blazor MultiSelect Dropdown component’s virtualization support allows users to navigate large lists of options efficiently by loading the items on demand. Virtualization can be used with filtering, grouping, custom values, and checkbox mode features. This feature can be enabled by setting the EnableVirtualization property to true.

Note: For more details, refer to the example of virtualization in the Blazor MultiSelect Dropdown component.

Tree Grid

Performance improvements in expand and collapse features

We are excited to announce significant performance improvements for Blazor TreeGrid with single root node data configurations. This enhancement targets scenarios with only one root parent row and thousands of child rows.

Following are the performance metrics comparing the old release with the current 2024 volume 2 release for 10,000 records:
