Draws an option button control (also known as a radio button) in the specified state and location.

public:
 static void DrawRadioButton(System::Drawing::Graphics ^ g, System::Drawing::Point glyphLocation, System::Windows::Forms::VisualStyles::RadioButtonState state);

public static void DrawRadioButton (System.Drawing.Graphics g, System.Drawing.Point glyphLocation, System.Windows.Forms.VisualStyles.RadioButtonState state);

static member DrawRadioButton : System.Drawing.Graphics * System.Drawing.Point * System.Windows.Forms.VisualStyles.RadioButtonState -> unit

Public Shared Sub DrawRadioButton (g As Graphics, glyphLocation As Point, state As RadioButtonState)

Parameters

g: Graphics

The Graphics used to draw the option button.

glyphLocation: Point

The Point to draw the option button glyph at.

state: RadioButtonState

One of the RadioButtonState values that specifies the visual state of the option button.

Remarks

If visual styles are enabled in the operating system and visual styles are applied to the current application, this method will draw the option button with the current visual style. Otherwise, this method will draw the option button with the classic Windows style.

Examples

The following code example uses the DrawRadioButton(Graphics, Point, Rectangle, String, Font, Boolean, RadioButtonState) method in a custom control's OnPaint method to draw an option button in the state determined by the location of the mouse pointer. This code example is part of a larger example provided for the RadioButtonRenderer class.

    // Draw the radio button in the current state.
protected:
    virtual void OnPaint(PaintEventArgs^ e) override
    {
        __super::OnPaint(e);

        RadioButtonRenderer::DrawRadioButton(e->Graphics,
            ClientRectangle.Location, TextRectangle, this->Text,
            this->Font, clicked, state);
    }

    // Draw the radio button in the checked or unchecked state.
protected:
    virtual void OnMouseDown(MouseEventArgs^ e) override
    {
        __super::OnMouseDown(e);

        if (!clicked)
        {
            clicked = true;
            this->Text = "Clicked!";
            state = RadioButtonState::CheckedPressed;
            Invalidate();
        }
        else
        {
            clicked = false;
            this->Text = "Click here";
            state = RadioButtonState::UncheckedNormal;
            Invalidate();
        }
    }

// Draw the radio button in the current state.
protected override void OnPaint(PaintEventArgs e)
{
    base.OnPaint(e);

    RadioButtonRenderer.DrawRadioButton(e.Graphics,
        ClientRectangle.Location, TextRectangle, this.Text,
        this.Font, clicked, state);
}

// Draw the radio button in the checked or unchecked state.
protected override void OnMouseDown(MouseEventArgs e)
{
    base.OnMouseDown(e);

    if (!clicked)
    {
        clicked = true;
        this.Text = "Clicked!";
        state = RadioButtonState.CheckedPressed;
        Invalidate();
    }
    else
    {
        clicked = false;
        this.Text = "Click here";
        state = RadioButtonState.UncheckedNormal;
        Invalidate();
    }
}

' Draw the radio button in the current state.

    MyBase.OnPaint(e)
    RadioButtonRenderer.DrawRadioButton(e.Graphics, _
        Me.ClientRectangle.Location, TextRectangle, Me.Text, _
        Me.Font, clicked, state)
End Sub

' Draw the radio button in the checked or unchecked state.
Protected Overrides Sub OnMouseDown(ByVal e As MouseEventArgs)
    MyBase.OnMouseDown(e)

    If Not clicked Then
        clicked = True
        Me.Text = "Clicked!"
        state = RadioButtonState.CheckedPressed
        Invalidate()
    Else
        clicked = False
        Me.Text = "Click here"
        state = RadioButtonState.UncheckedNormal
        Invalidate()
