使用例
[Visual Basic, C#, C++] ErrorProvider クラスを使用して、データ入力エラーをユーザーに通知する方法を次の例に示します。 TextBox コントロール、 NumericUpDown コントロール、および ComboBox コントロールが配置された Form を作成する例を次に示します。内容の検証は各コントロールで実行し、各コントロールの ErrorProvider も作成します。 BlinkRate プロパティと BlinkStyle プロパティ、および SetIconAlignment メソッドと SetIconPadding メソッドを使用してエラー アイコンのオプションを設定する例を次に示します。 SetError メソッドは、コントロールの内容に応じて、コントロールの Validated イベント時に、適切なエラー テキスト付きまたはエラー テキストなしで呼び出されます。
