repeaterコントロールを使用したプログラムを 1 つ作成しました。これで、repeaterページングも使用できるようになりました。ページ番号をクリックすると、その番号が他の色で強調表示されます。そして、それはうまくいきます。今私の問題は、View allボタンも持っていることです。そのボタンをクリックすると。のみの色を変更したいview all 。番号ではありません。そして、私が何をしていても、[すべて表示] ボタンをクリックすると、ページ番号 1 と Vie ウォールの両方が強調表示されます。提案を教えてください。私は 1 つのリンク ボタンview allと、ページング用のリンク ボタンを持っているリピーターを取りました。そのために今、私は何をすべきですか?? そのために使うべきJavascriptですか？それともバックエンドコーディングで行うのでしょうか? aspx ファイル コード
