copied!<p>This is my approach for binding a list of radio buttons to an enum.</p> <p>Using the Enum as a string in the button's Tag property, I use the <strong>Binding.Format</strong> and <strong>Binding.Parse</strong> event to decide which button should be checked.</p> <pre><code>public enum OptionEnum { Option1 = 0, Option2 } OptionEnum _rbEnum = OptionEnum.Option1; OptionEnum PropertyRBEnum { get { return _rbEnum; } set { _rbEnum = value; RaisePropertyChanged("PropertyRBEnum"); } } public static void FormatSelectedEnum<T>(object sender, ConvertEventArgs args) where T : struct { Binding binding = (sender as Binding); if (binding == null) return; Control button = binding.Control; if (button == null || args.DesiredType != typeof(Boolean)) return; T value = (T)args.Value; T controlValue; if (Enum.TryParse(button.Tag.ToString(), out controlValue)) { args.Value = value.Equals(controlValue); } else { Exception ex = new Exception("String not found in Enum"); ex.Data.Add("Tag", button.Tag); throw ex; } } public static void ParseSelectedEnum<T>(object sender, ConvertEventArgs args) where T : struct { Binding binding = (sender as Binding); if (binding == null) return; Control button = binding.Control; bool value = (bool)args.Value; if (button == null || value != true) return; T controlValue; if (Enum.TryParse(button.Tag.ToString(), out controlValue)) { args.Value = controlValue; } else { Exception ex = new Exception("String not found in Enum"); ex.Data.Add("Tag", button.Tag); throw ex; } } </code></pre> <p>Then setup your data binding like this:</p> <pre><code>radioButton1.Tag = "Option1"; radioButton2.Tag = "Option2"; foreach (RadioButtonUx rb in new RadioButtonUx[] { radioButton1, radioButton2 }) { Binding b = new Binding("Checked", this, "PropertyRBEnum"); b.Format += FormatSelectedRadioButton<OptionEnum>; b.Parse += ParseSelectedRadioButton<OptionEnum>; rb.DataBindings.Add(b); } </code></pre>
