MultiColumnComboBox Filter

Updated on Oct 1, 2026

The MultiColumnComboBox component allows users to filter items by their text, so they can find the one they need faster.

To enable filtering, set the Filterable parameter to true. The filtering is case insensitive.

You can also use the OnRead event to:

• Get the applied filtering criteria.
• Implement custom (server) filtering and set data dynamically.

Filtering looks in the TextField, and the filter is reset when the dropdown closes.

Filter Operator

The default filter operator is starts with. You can choose a different operator through the FilterOperator parameter that takes a member of the Telerik.Blazor.StringFilterOperator enum.

Performance

By default, the filtering is debounced with 150ms. Configure that with the DebounceDelay parameter of the component.
