基本的な使用方法

列選択機能は、GridSelectionMode 値を受け取る ColumnSelection 入力によって有効にすることができます。

インタラクション

デフォルトの選択モードは None です。Single または Multiple に設定されると、すべての列は Selectable になります。列を選択するには、列をクリックして Selected としてマークします。列が選択不可な場合、ホバー時に選択スタイルはヘッダーに適用されません。

複数列ヘッダー機能は Selectable 入力に反映されません。その子の 1 つ以上で選択動作が有効な場合、ColumnGroupComponent は Selectable です。さらに、すべての Selectable 子孫が Selected である場合、コンポーネントは Selected としてマークされます。

*Country Information 列グループでは、City 列 および Postal code 列のみを選択できます。

キーボードの組み合わせ

キーボードの組み合わせは、グリッドの ColumnSelection 入力が multiple に設定されている場合にのみ使用できます。

列の選択機能のキーボード ナビゲーションには 2 つのオプションがあります。

• 複数列選択 - Ctrl キーを押しながら、すべての選択可能なヘッダー セルを クリック。
• 範囲列の選択 - Shift キーを押しながら + クリック、間にあるすべての選択可能な列を選択します。

API 操作

API は、非表示列に関していくつかの追加機能を提供し、対応する setter を設定することにより、すべての非表示列を Selected としてマークできます。

上記は ColumnGroupComponent にも適用されますが、Selected プロパティを変更する場合、その子孫の状態を変更します。

API 操作の詳細については、API リファレンス セクションを参照してください。

スタイル設定

定義済みのテーマに加えて、利用可能な CSS プロパティのいくつかを設定することで、グリッドをさらにカスタマイズできます。一部の色を変更したい場合は、最初にグリッドの class を設定する必要があります。

<IgbGrid class="grid"></IgbGrid>
razor

次に、そのクラスに関連する CSS プロパティを設定します。

.grid {
    --ig-grid-row-selected-background: #0062A3;
    --ig-grid-row-selected-text-color: #ecaa53;
    --ig-grid-row-selected-hover-background: #0062A3;
    --ig-grid-header-selected-text-color: #ecaa53;
    --ig-grid-header-selected-background: #0062A3;
    --ig-grid-row-selected-hover-text-color: #ecaa53;
    --ig-grid-row-selected-hover-background: #0062A3;
}
