非営利団体のギフトエントリグリッドテンプレートの列コンポーネントの設定

セルの表示コンポーネント

デフォルトでは、[仕様] 列コンポーネントには空白の値が表示されます。1 つの指定が [ギフトエントリ] 行に関連付けられている場合、列コンポーネントはその指定に金額を連結して、グリッド (100 ドルなど) に表示します。 2 つ以上の指定がある場合、グリッドには集計値 (2 つの指定など) が表示されます。

セル表示コンポーネントには次の要件があります。

• JavaScriptjs ファイルの tagName 値。
• グリッドから渡される受信プロパティとして機能する @api params。

このサンプルでは、表示コンポーネントにバーコード列が表示されています。データが入力される前は、待機中として表示されます。一致する値が検出されると、列が更新されて支援者の名前が表示されます。

セルの編集コンポーネント

デフォルトテンプレートの「指定」列の編集コンポーネントには、参照項目と同様に機能する Lightning 入力項目があります。ユーザーが値を入力すると、カスタムバーコードオブジェクトで一致する値が検索されます。一致が見つかった場合、そのレコードの値がギフトエントリグリッドの他の列に入力されます。

セルの編集コンポーネントには次の要件があります。

• JavaScript ファイルの tagName パラメータ。
• true に設定された JavaScript ファイルの isPopup パラメータ。
• @salesforce/messageChannel/lightning__giftEntryGridComponentAction からの Gift Entry Grid Lightning Message Service チャネルの使用。
• 次のサンプルでコールアウトされているその他のメソッドと変数。
