Blazor Tree Grid の列非表示

Ignite UI for Blazor には組み込み列非表示 UI があり、これを Blazor Tree Grid のツールバーから使用して列の表示状態を変更できます。開発者は、必要に応じてページ内の任意の場所に列非表示 UI を柔軟に定義できます。Blazor Tree Grid 列の非表示機能は、グリッドのサイズを小さくし、冗長なフィールドをタブで移動する必要をなくしたい場合に特に便利です。

すぐに使用できる機能のフルセット は、ページング、ソート、フィルタリング、編集、グループ化から行と列の仮想化まで、あらゆる機能をカバーします。.NET 開発者には制限はありません。

Tree Grid のセットアップ

IgbTreeGrid を作成してからデータをバインドします。列でフィルタリングとソートも有効にします。

<IgbTreeGrid Data=northwindEmployees AutoGenerate=false Width="100%" Height="100%" AllowFiltering=true>
    <IgbColumn Field="Name" Sortable=true Hidden=true></IgbColumn>
    <IgbColumn Field="ID" Sortable=true Hidden=true></IgbColumn>
    <IgbColumn Field="Title" Sortable=true></IgbColumn>
    <IgbColumn Field="HireDate" Sortable=true></IgbColumn>
    <IgbColumn Field="Age" Sortable=true></IgbColumn>
    <IgbColumn Field="Address" Sortable=true></IgbColumn>
    <IgbColumn Field="City" Sortable=true></IgbColumn>
    <IgbColumn Field="Country" Sortable=true></IgbColumn>
    <IgbColumn Field="Fax" Sortable=true></IgbColumn>
    <IgbColumn Field="PostalCode" Sortable=true></IgbColumn>
    <IgbColumn Field="Phone" Sortable=true></IgbColumn>
</IgbTreeGrid>
razor

ツールバーの列非表示 UI

定義済みの列非表示 UI は、IgbTreeGrid のツールバーの DropDown 内に配置されます。列非表示の UI をこのドロップダウンを使用して表示/非表示にできます。

これには、IgbTreeGrid 内に IgbGridToolbarActions と IgbGridToolbarHiding の両方を設定することだけです。ツールバーにタイトルを追加するには、IgbGridToolbarTitle を設定し、Tree Grid のラッパーにカスタム スタイルを設定します。

<IgbTreeGrid Data=northwindEmployees>
    <IgbGridToolbar>
        <IgbGridToolbarActions>
            <IgbGridToolbarHiding></IgbGridToolbarHiding>
        </IgbGridToolbarActions>
    </IgbGridToolbar>
</IgbTreeGrid>
razor

IgbTreeGrid にはツールバーの列非表示 UI に便利なプロパティがあります。

Title プロパティを使用して、ツールバーのドロップダウン ボタンに表示されるタイトルを設定します。

<IgbTreeGrid Data=northwindEmployees>
    <IgbGridToolbar>
        <IgbGridToolbarActions>
            <IgbGridToolbarHiding @ref=HidingAction Title="Column Hiding"></IgbGridToolbarHiding>
        </IgbGridToolbarActions>
    </IgbGridToolbar>
</IgbTreeGrid>
razor

このトピックのはじめにあるコードの結果は Blazor 列非表示の例のセクションで確認できます。

列の非表示の無効化

列の DisableHiding プロパティを true に設定すると、ユーザーが列非表示 UI によって列を非表示にできません。

<IgbTreeGrid Data=northwindEmployees AutoGenerate=false>
    <IgbColumn Field="Name" Sortable=true DisableHiding=true></IgbColumn>
    <IgbColumn Field="Title" Sortable=true DisableHiding=true></IgbColumn>
</IgbTreeGrid>
razor

スタイル設定

グリッドは、利用可能な CSS 変数の一部を設定することでさらにカスタマイズできます。 これを実現するために、最初にグリッドに割り当てるクラスを使用します。

<IgbTreeGrid Id="treeGrid"></IgbTreeGrid>
razor

次に、関連するコンポーネントに関連する CSS 変数を設定します。スタイルも igx-column-actions にのみ適用するので、グリッドの残りの部分は影響を受けません。

#treeGrid {
    /* Main Column Actions styles */
    --ig-column-actions-background-color: #292826;
    --ig-column-actions-title-color: #ffcd0f;

    /* Checkbox styles */
    --ig-checkbox-tick-color: #292826;
    --ig-checkbox-label-color: #ffcd0f;
    --ig-checkbox-empty-color: #ffcd0f;
    --ig-checkbox-fill-color: #ffcd0f;

    /* Input styles */
    --ig-input-group-idle-text-color: white;
    --ig-input-group-filled-text-color: #ffcd0f;
    --ig-input-group-focused-text-color: #ffcd0f;
    --ig-input-group-focused-border-color: #ffcd0f;
    --ig-input-group-focused-secondary-color: #ffcd0f;

    /* Buttons styles */
    --ig-button-foreground: #292826;
    --ig-button-background: #ffcd0f;
    --ig-button-hover-background: #404040;
    --ig-button-hover-foreground: #ffcd0f;
    --ig-button-focus-background: #ffcd0f;
    --ig-button-focus-foreground: black;
    --ig-button-focus-visible-background: #ffcd0f;
    --ig-button-focus-visible-foreground: black;
    --ig-button-disabled-foreground: #ffcd0f;
