RadRadioButton

Initializes a new instance of the RadRadioButton class. Creates a radio button with default settings including automatic checking behavior and tab stop functionality.

Gets or sets a value indicating whether the IsChecked value and the appearance of the control automatically change when the control is clicked. When true and the radio button is part of a group, it automatically ensures that only one control is checked at a time. When false, a group of radio button controls will not act as a mutually exclusive group and the IsChecked property must be updated in code.

Gets or sets a value indicating whether the control is automatically resized to display its entire contents. When enabled, the radio button will automatically adjust its size to accommodate its text and visual elements.

[Browsable(true)]
public override bool AutoSize { get; set; }

Overrides: RadControl.AutoSize

Gets the RadRadioButtonElement that represents the visual element of this radio button control. This element contains the visual styling and behavior logic for the radio button including the check mark and text layout.

Gets the default size of the RadRadioButton control. This property returns the recommended dimensions for the radio button when no explicit size is set.

protected override Size DefaultSize { get; }

Overrides: RadToggleButton.DefaultSize

Gets or sets the alignment of the radio button's check mark relative to the text. This property determines where the radio button circle appears in relation to the button text.

Gets or sets a value indicating whether the user can give focus to this radio button using the TAB key. For radio buttons, this is automatically managed to ensure proper tab navigation within radio button groups. Only the checked radio button in a group typically receives tab focus.

Handles the toggle state changed event from the button element and manages tab stop behavior for radio button groups. This method ensures proper keyboard navigation within radio button groups when the checked state changes.

protected override void ButtonElement_ToggleStateChanged(object sender, StateChangedEventArgs args)

Overrides: RadToggleButton.ButtonElement_ToggleStateChanged(object, StateChangedEventArgs)

Creates the accessibility instance for the radio button control to support assistive technologies. Returns a specialized accessibility object when accessibility objects are enabled.

protected override AccessibleObject CreateAccessibilityInstance()

Overrides: RadToggleButton.CreateAccessibilityInstance()

Creates the main button element that is specific for RadRadioButton. This method is responsible for instantiating the underlying visual element that provides the radio button functionality.

protected override RadButtonElement CreateButtonElement()

Overrides: RadToggleButton.CreateButtonElement()

Creates the child items and establishes event handlers for the radio button control. This method sets up the property change notification system for the button element.

protected override void CreateChildItems(RadElement parent)

Overrides: RadToggleButton.CreateChildItems(RadElement)

Initializes the UI Automation provider for the radio button control. This method creates and returns the automation provider that enables assistive technologies to interact with the radio button.

protected override IRadRawElementProviderFragmentRoot InitializeUIAutomationProvider()

Overrides: RadToggleButton.InitializeUIAutomationProvider()

Raises the Enter event and handles keyboard navigation behavior for radio button groups. When entered via keyboard navigation, this method may automatically check the radio button or update tab stops.

protected override void OnEnter(EventArgs e)

Overrides: Control.OnEnter(EventArgs)

Raises the GotFocus event and invalidates the control to update its visual appearance. This method ensures the radio button displays the appropriate focus indicators when it receives focus.

protected override void OnGotFocus(EventArgs e)

Overrides: RadButtonBase.OnGotFocus(EventArgs)

Raises the CheckStateChanged event when the check state of the radio button changes. This method provides notification when the radio button's checked state is modified.

protected override void res_CheckStateChanged(object sender, EventArgs e)

Overrides: RadToggleButton.res_CheckStateChanged(object, EventArgs)

Raises the CheckStateChanging event when the check state of the radio button is about to change. This method provides notification before the radio button's checked state is modified, allowing for cancellation.

protected override void res_CheckStateChanging(object sender, CheckStateChangingEventArgs args)

Overrides: RadToggleButton.res_CheckStateChanging(object, CheckStateChangingEventArgs)

Manages tab stop behavior for radio button groups to ensure proper keyboard navigation. This method coordinates tab stops among radio buttons in the same container to maintain standard Windows behavior.
