DevExpress Blazor ComboBox

DxComboBox<TData, TValue> is a text editor with a searchable drop-down list. It binds to strongly-typed collections or custom objects, supports multi-column layouts, grouping, virtual scrolling, cascading dropdowns, and fully customizable item and edit-box templates.

When to Use This Skill

• Add a single-selection dropdown or selector to a Blazor form
• Bind to any IEnumerable<T>, IQueryable<T>, or async collection
• Enable live search/filter as the user types
• Display grouped items with a group header
• Create cascading (dependent) dropdowns
• Show multiple columns in the drop-down list
• Customise item rendering via ItemDisplayTemplate or EditBoxDisplayTemplate
• Add a Clear button, custom command buttons, or placeholder text
• Validate ComboBox selection inside a standard <EditForm>
• Use virtual scrolling for large lists
