Blazor Tree Grid Column Pinning

Blazor Tree Grid의 Ignite UI for Blazor Column Pinning 기능을 사용하면 개발자가 특정 열을 원하는 순서로 잠그고 사용자가 IgbGrid 가로로 스크롤하더라도 항상 가시성을 확보할 수 있습니다. Blazor Tree Grid 툴바를 통해 액세스할 수 있는 Column Pinning을 위한 통합 UI가 있습니다. 또한 개발자는 열의 고정 상태를 변경하는 사용자 지정 사용자 인터페이스를 빌드할 수 있는 유연성을 갖추고 있습니다.

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。

열 고정 API

열 고정은 IgbColumn의 Pinned 속성을 통해 제어됩니다. 고정된 열은 기본적으로 IgbTreeGrid의 왼쪽에 렌더링되며 IgbTreeGrid 본문에서 고정 해제된 열의 가로 스크롤을 통해 고정된 상태로 유지됩니다.

​IgbTreeGrid의 PinColumn 또는 IgbTreeGrid의 UnpinColumn 메서드를 사용하여 필드 이름으로 열을 고정하거나 고정 해제할 수도 있습니다.

두 메서드 모두 해당 작업의 성공 여부를 나타내는 부울 값을 반환합니다. 일반적으로 실패하는 이유는 열이 이미 원하는 상태에 있기 때문입니다.

열은 가장 오른쪽에 고정된 열의 오른쪽에 고정되어 있습니다. 고정된 열의 순서를 변경하려면 ColumnPin 이벤트를 구독하고 이벤트 인수의 InsertAtIndex 속성을 원하는 위치 인덱스로 변경하면 됩니다.

열은 가장 오른쪽에 고정된 열의 오른쪽에 고정됩니다. 고정된 열의 순서 변경은 이벤트를 구독 ColumnPinScript 하고 이벤트 인수의 속성을 원하는 위치 인덱스로 변경 InsertAtIndex 하기 위한 JavaScript 함수를 제공하여 수행할 수 있습니다.

<IgbTreeGrid Data=data AutoGenerate=true ColumnPinScript="onColumnPin"/>


//In JavaScript
function onColumnPin(e) {
    if (e.detail.column.field == "Country") {
        e.detail.insertAtIndex = 0;
    }
}

igRegisterScript("onColumnPin", onColumnPin, false);
razor

고정 위치

​Pinning 구성 옵션을 통해 열 고정 위치를 변경할 수 있습니다. 열 위치를 시작 또는 끝으로 설정할 수 있습니다. 끝으로 설정하면 열이 고정 해제된 열 뒤의 그리드 끝에서 렌더링됩니다. 고정되지 않은 열은 가로로 스크롤할 수 있지만 고정된 열은 오른쪽에 고정된 상태로 유지됩니다.

<IgbTreeGrid Data=data AutoGenerate=true Pinning="pinningConfig"></IgbTreeGrid>

@code {
    private IgbPinningConfig pinningConfig = new() {
        Columns = ColumnPinningPosition.End
    };

사용자 정의 열 고정 UI

관련 API를 통해 사용자 정의 UI를 정의하고 열의 핀 상태를 변경할 수 있습니다.

도구 모음 대신 최종 사용자가 클릭하여 특정 열의 핀 상태를 변경할 수 있는 열 헤더에 핀 아이콘을 정의한다고 가정해 보겠습니다.

이는 사용자 정의 아이콘이 있는 열의 헤더 템플릿을 생성하여 수행할 수 있습니다.

고정 제한

• 열 너비를 백분율(%)로 설정하면 고정된 열이 있을 때 IgbTreeGrid 본문과 헤더 내용이 잘못 정렬됩니다. 열 고정이 올바르게 작동하려면 열 너비가 픽셀(px) 단위이거나 IgbTreeGrid에 의해 자동 할당되어야 합니다.

스타일링

사전 정의된 테마 외에도 사용 가능한 CSS 속성 중 일부를 설정하여 그리드를 추가로 사용자 정의할 수 있습니다. 일부 색상을 변경하려면 먼저 그리드의 ID 설정해야 합니다.

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

그런 다음 관련 CSS 속성을 이 클래스로 설정합니다.

#grid {
    --ig-grid-pinned-border-width: 5px;
    --ig-grid-pinned-border-color: #FFCD0F;
    --ig-grid-pinned-border-style: double;
    --ig-grid-cell-active-border-color: #FFCD0F;
