グリッド行の「数量」が「0」の場合、グリッド行のチェックボックスを選択しないようにするにはどうすればよいですか。 私は以下のコードを持っていますが、1行が選択されている限り、Qty値を変更せずに2行目などを選択できるので、それでも可能です。 上記の各ボタンから選択した行は、form2に送信されます。qtyが1より大きくない場合、チェックボックスをオフにします

「Form2」のスクリーンショットが追加されたようですね。あなたが 'Form2'を修正するのを手助けする人はいないでしょう。もしあなたがそれについての一つの詳細を含んでいなければ（それに含まれているグリッド定義など）、 [質問を編集]（https://stackoverflow.com/posts/46600500/edit）し、 'Form2'のグリッドとその行チェックボックスがどのように/どこに定義されているかについて十分な詳細を追加してください。 –
HI。スクリーンショットは、form1のdatagridview1です。このフォームから選択されたチェックボックスは、フォーム2に送信されます。しかし、ほとんどのユーザーはチェックボックスを選択しますが、何らかの形で「数量」の値を変更することを忘れてしまいます。 – shabs
あなたのタイトルと本文の違いに注意してください。 "qtyは1より大きくない"（ 'qty <= 1'）と" Qty "が" 0 ""（ 'qty <1'）です。 – Flater
