A checkbox input component that supports two-state (checked/unchecked) or tri-state (checked/unchecked/indeterminate) modes. RadzenCheckBox provides data binding, validation, and keyboard accessibility for boolean or nullable boolean values. In two-state mode, the value toggles between true and false. In tri-state mode (TriState = true), the value cycles through false → null → true → false. Supports keyboard interaction (Space/Enter to toggle) and integrates with Blazor EditContext for form validation.

public class RadzenCheckBox<TValue> : FormComponent<TValue>, IComponent, IHandleEvent, IHandleAfterRender, IRadzenFormComponent| Name | Description |
|---|---|
| TValue | The type of the bound value. Typically bool for two-state or bool? for tri-state checkboxes. |
Basic two-state checkbox:
<RadzenCheckBox @bind-Value=@isChecked TValue="bool" />Tri-state checkbox with change handler:
<RadzenCheckBox @bind-Value=@nullableBool TValue="bool?" TriState="true" Change=@(args => Console.WriteLine($"Value: {args}")) />Read-only checkbox for display purposes:
<RadzenCheckBox Value=@isEnabled TValue="bool" ReadOnly="true" />A checkbox input component that supports two-state (checked/unchecked) or tri-state (checked/unchecked/indeterminate) modes. RadzenCheckBox provides data binding, validation, and keyboard accessibility for boolean or nullable boolean values. In two-state mode, the value toggles between true and false. In tri-state mode (TriState = true), the value cycles through false → null → true → false. Supports keyboard interaction (Space/Enter to toggle) and integrates with Blazor EditContext for form validation.
public RadzenCheckBox<TValue>()Gets or sets additional HTML attributes to be applied to the underlying input element. This allows passing custom attributes like data-* attributes, aria-* attributes, or other HTML attributes directly to the input.
public IReadOnlyDictionary<string, object> InputAttributes { get; set; }| Type | Description |
|---|---|
| IReadOnlyDictionary<string, object> | Gets or sets additional HTML attributes to be applied to the underlying input element. This allows passing custom attributes like data-* attributes, aria-* attributes, or other HTML attributes directly to the input. |
Gets or sets whether the checkbox is read-only and cannot be toggled by user interaction. When true, the checkbox displays its current state but prevents clicking or keyboard toggling. Useful for displaying checkbox state in view-only scenarios.
public bool ReadOnly { get; set; }| Type | Description |
|---|---|
| bool | Gets or sets whether the checkbox is read-only and cannot be toggled by user interaction. When true, the checkbox displays its current state but prevents clicking or keyboard toggling. Useful for displaying checkbox state in view-only scenarios. |
Gets or sets whether the checkbox supports three states: checked (true), unchecked (false), and indeterminate (null). When enabled, clicking cycles through all three states. Use with nullable boolean (bool?) values.
public bool TriState { get; set; }| Type | Description |
|---|---|
| bool | Gets or sets whether the checkbox supports three states: checked (true), unchecked (false), and indeterminate (null). When enabled, clicking cycles through all three states. Use with nullable boolean (bool?) values. |
