Commandsでこれを実現できます。 ICommandfor each の toyを作成し、プロパティをそれにTabItem ViewModelsバインドしますButtons CommandCommand
これRelayCommandは、このようなものを処理するための非常に一般的な方法であり、アプリケーション全体で使用できます
中継コマンド:
public class RelayCommand : ICommand
{
#region Fields
readonly Action<object> _execute;
readonly Predicate<object> _canExecute;
#endregion
#region Constructors
/// <summary>
/// Initializes a new instance of the <see cref="RelayCommand"/> class.
/// </summary>
/// <param name="execute">The execute.</param>
public RelayCommand(Action<object> execute) : this(execute, null) { }
/// <summary>
/// Initializes a new instance of the <see cref="RelayCommand"/> class.
/// </summary>
/// <param name="execute">The action to execute.</param>
/// <param name="canExecute">The can execute.</param>
/// <exception cref="System.ArgumentNullException">execute</exception>
public RelayCommand(Action<object> execute, Predicate<object> canExecute)
{
if (execute == null)
throw new ArgumentNullException("execute");
_execute = execute;
_canExecute = canExecute;
}
#endregion
#region ICommand Members
/// <summary>
/// Defines the method that determines whether the command can execute in its current state.
/// </summary>
/// <param name="parameter">Data used by the command. If the command does not require data to be passed, this object can be set to null.</param>
/// <returns>
/// true if this command can be executed; otherwise, false.
/// </returns>
[DebuggerStepThrough]
public bool CanExecute(object parameter)
{
return _canExecute == null ? true : _canExecute(parameter);
}
/// <summary>
/// Occurs when changes occur that affect whether or not the command should execute.
/// </summary>
public event EventHandler CanExecuteChanged
{
add { CommandManager.RequerySuggested += value; }
remove { CommandManager.RequerySuggested -= value; }
}
/// <summary>
/// Defines the method to be called when the command is invoked.
/// </summary>
/// <param name="parameter">Data used by the command. If the command does not require data to be passed, this object can be set to null.</param>
public void Execute(object parameter)
{
_execute(parameter);
}
#endregion
}
そして、アプリケーションで次のように使用します
ViewModel またはコントロール:
public class VersionPanel1_2_8 : VersionPanel
{
public ICommand MyCommand { get; internal set; }
public VersionPanel1_2_8()
{
MyCommand = new RelayCommand(x => MethodToExecute());
}
private void MethodToExecute()
{
}
}
