IWindowsFormsEditorService インターフェイス
UITypeEditors にインターフェイスを提供して、Windows フォームを表示したり、デザイン モードでプロパティ グリッド コントロールからドロップダウン領域のコントロールを表示します。
この型のすべてのメンバの一覧については、IWindowsFormsEditorService メンバ を参照してください。
Public Interface IWindowsFormsEditorService

public interface IWindowsFormsEditorService
解説
IWindowsFormsEditorService は、 PropertyGrid コントロールの GetService メソッドを通じてだけ使用できます。
このサービスは、通常、 UITypeEditor の EditValue メソッドからフォームを表示するために使用されます。 PropertyGrid が UITypeEditor の EditValue メソッドを呼び出して、プロパティの値を編集するためのユーザー インターフェイスを提供する場合、 EditValue メソッドには、通常 IWindowsFormsEditorService のインスタンスを提供する IServiceProvider への参照が渡されます。このサービスのメソッドを使用することによって、ダイアログ ボックスやフォームを表示したり、ドロップダウン コンテナ内の Control を表示できます。このコンテナは、編集中の値を持つ値フィールド領域に近いプロパティ グリッドの上に表示されます。
