How do I group Windows Form radio buttons

Question

How can I group the radio buttons in Windows Form application  a lot like ASP NET s radiobuttonlist      So I can switch between each case chosen from the options

User · Accepted Answer

Put all radio buttons for a group in a container object like a Panel or a GroupBox   That will automatically group them together in Windows Forms

User · Answer

Look at placing your radio buttons in a GroupBox

User · Answer

If you cannot put them into one container  then you have to write code to change checked state of each RadioButton   private void rbDataSourceFile CheckedChanged object sender  EventArgs e        rbDataSourceNet Checked    rbDataSourceFile Checked     private void rbDataSourceNet CheckedChanged object sender  EventArgs e      rbDataSourceFile Checked    rbDataSourceNet Checked

I like the concept of grouping RadioButtons in WPF  There is a property GroupName that specifies which RadioButton controls are mutually exclusive  http   msdn microsoft com de-de library system windows controls radiobutton aspx    So I wrote a derived class for WinForms that supports this feature   using System  using System Collections Generic  using System Linq  using System Text  using System Windows Forms  using System Diagnostics  using System Windows Forms VisualStyles  using System Drawing  using System ComponentModel   namespace Use your own       public class AdvancedRadioButton   CheckBox               public enum Level   Parent  Form              Category  AdvancedRadioButton            Description  Gets or sets the level that specifies which RadioButton controls are affected             DefaultValue Level Parent           public Level GroupNameLevel   get  set              Category  AdvancedRadioButton            Description  Gets or sets the name that specifies which RadioButton controls are mutually exclusive             public string GroupName   get  set             protected override void OnCheckedChanged EventArgs e                        base OnCheckedChanged e                if  Checked                                var arbControls    dynamic null                  switch  GroupNameLevel                                        case Level Parent                          if  this Parent    null                              arbControls   GetAll this Parent  typeof AdvancedRadioButton                            break                      case Level Form                          Form form   this FindForm                            if  form    null                              arbControls   GetAll this FindForm    typeof AdvancedRadioButton                            break                                    if  arbControls    null                      foreach  Control control in arbControls                          if  control    this  amp  amp                               control as AdvancedRadioButton  GroupName    this GroupName                               control as AdvancedRadioButton  Checked   false                                   protected override void OnClick EventArgs e                        if   Checked                  base OnClick e                      protected override void OnPaint PaintEventArgs pevent                        CheckBoxRenderer DrawParentBackground pevent Graphics  pevent ClipRectangle  this                RadioButtonState radioButtonState              if  Checked                                radioButtonState   RadioButtonState CheckedNormal                  if  Focused                      radioButtonState   RadioButtonState CheckedHot                  if   Enabled                      radioButtonState   RadioButtonState CheckedDisabled                            else                               radioButtonState   RadioButtonState UncheckedNormal                  if  Focused                      radioButtonState   RadioButtonState UncheckedHot                  if   Enabled                      radioButtonState   RadioButtonState UncheckedDisabled                             Size glyphSize   RadioButtonRenderer GetGlyphSize pevent Graphics  radioButtonState               Rectangle rect   pevent ClipRectangle              rect Width -  glyphSize Width              rect Location   new Point rect Left   glyphSize Width  rect Top                RadioButtonRenderer DrawRadioButton pevent Graphics  new System Drawing Point 0  rect Height   2 - glyphSize Height   2   rect  this Text  this Font  this Focused  radioButtonState                      private IEnumerable lt Control gt  GetAll Control control  Type type                        var controls   control Controls Cast lt Control gt                  return controls SelectMany ctrl   gt  GetAll ctrl  type                                          Concat controls                                         Where c   gt  c GetType      type

GroupBox is better But not only group box  even you can use Panels  System Windows Forms Panel     That is very usefully when you are designing Internet Protocol version 4 setting dialog  Check it with your pc windows  then you can understand the behavior

User · Answer

You should place all the radio buttons of the group inside the same container such as a GroupBox or Panel

User · Answer

Put radio buttons inside GroupBox  or other panel

User · Answer

All radio buttons inside of a share container are in the same group by default  Means  if you check one of them - others will be unchecked  If you want to create independent groups of radio buttons  you must situate them into different containers such as Group Box  or control their Checked state through code behind
