'助けてください'。編集ボタンが押されたときに、ビューモデルから別のビューを呼び出す必要があります。showdailog() もう使えません。このビューから別の子ビューを呼び出しています。

ビューモデル:

    private ICommand _editRowData;

    public ICommand EditRowData
    {
        get { return _editRowData ?? (_editRowData = new CommandHandler(() => RowDataAction(), _canExecute)); }
    }


   private SecondWindowViewModel childView;
    public void RowDataAction()
    {
        childView = new SecondWindowViewModel();
        //MessageBox.Show("Edit Button Pressed");
        SecondWindow view = new SecondWindow()
        {
            DataContext = childView

        };

        childView.Labelcontent = "kala";

        view.ShowDailog();

        //view.ShowDailog() is giving me error. Please explain and provide me solve.

ボタンのバインドを次のように変更します。

<Button Command="{Binding Path=DataContext.EditRowData, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ItemsControl}}" ... etc
