RadioButton

RadioButton is a common component and describes what action will occur when you select it.
A RadioButton can only contain an icon, and can be created using style.

Create with Style

To create a radio button using style, follow these steps:

1. Create RadioButton using the default constructor:

   
                   
   C#
                   
   
                       
   Copy
                       
   
                   
               
   RadioButton utilityRadioButton = new RadioButton();
   

2. Apply style to RadioButton:

   
                   
   C#
                   
   
                       
   Copy
                       
   
                   
               
   ButtonStyle utilityStyle = new ButtonStyle
   {
       Icon = new ImageViewStyle
       {
           Size =  new Size(48, 48),
           ResourceUrl = new Selector<string>
           {
               Normal = "btn_radio_off.png",
               Selected = "btn_radio_on.png",
               Disabled = "btn_radio_off.png",
               DisabledSelected = "btn_radio_on.png",
           }
       }
   }
   utilityRadioButton.ApplyStyle(utilityStyle);
   utilityRadioButton.Size = new Size(48, 48);
   root.Add(utilityRadioButton);
   

Following output is generated when a radio button is created using style:

Responding to Clicked

When you click a radio button, the radio button instance receives a clicked event. You can declare the clicked event handler as follows:

                
C#
                

                    
Copy
                    

                
            
RadioButton button = new RadioButton();
button.Clicked += OnClicked;

                
C#
                

                    
Copy
                    

                
            
private void OnClicked(object sender, ClickedEventArgs e)
{
    // Do something in response to RadioButton click
}

Responding to StateChangedEvent

RadioButton has the following eight states Normal, Focused, Disabled, Selected, Pressed, DisabledFocused, SelectedFocused, and DisabledSelected.
When you change the radio button state to focus or disable, the radio button instance receives a state changed event:

                
C#
                

                    
Copy
                    

                
            
RadioButton button = new RadioButton();
button.ControlStateChangedEvent += OnStateChange;

                
C#
                

                    
Copy
                    

                
            
private void OnStateChange(object sender, Control.ControlStateChangedEventArgs e)
{
    // Do something in response to state change
}
