Blazor Tree Grid State Persistence
Blazor 트리 그리드의 Ignite UI for Blazor 상태 지속성을 통해 개발자는 그리드 상태를 쉽게 저장하고 복원할 수 있습니다. Blazor IgbGridState IgbTreeGrid에 적용되면 개발자가 모든 시나리오에서 상태 유지를 달성하는 데 사용할 수 있는 및 ApplyStateFromStringAsync 메서드가 노출 GetStateAsStringAsync 됩니다.
Supported Features
IgbGridState 지시문은 다음 기능의 상태 저장 및 복원을 지원합니다.
- Sorting
- Filtering
- 고급 필터링
- 페이징
- CellSelection
- 행 선택
- ColumnSelection
- RowPinning
- 확장
- 그룹화 기준
- Columns
- Multi column headers
- 열 순서
- Column properties defined by the
IColumnStateinterface.
Usage
직렬화된 JSON 문자열을 GetStateAsStringAsync 반환하므로 개발자는 이를 가져와서 모든 데이터 저장소(데이터베이스, 클라우드, 브라우저 localStorage 등)에 저장할 수 있습니다.
개발자는 기능 이름이 있는 배열을 인수로 전달하여 특정 기능에 대한 상태만 가져오도록 선택할 수 있습니다. 빈 배열은 기본 상태 옵션을 사용하게 됩니다.
<IgbTreeGrid>
<IgbGridState @ref="gridState"></IgbGridState>
</IgbTreeGrid>
@code {
// get all features` state in a serialized JSON string
string stateString = gridState.GetStateAsStringAsync(new string[0]);
// get the sorting and filtering expressions
string sortingFilteringStates = gridState.GetStateAsStringAsync(new string[] { "sorting", "filtering" });
}
razorApplyStateFromStringAsync- 이 메서드는 직렬화된 JSON 문자열을 인수로 허용하고 JSON 문자열 또는 지정된 기능에 있는 각 기능의 상태를 두 번째 인수로 복원합니다.
gridState.ApplyStateFromStringAsync(gridStateString, new string[0]);
gridState.ApplyStateFromStringAsync(sortingFilteringStates, new string[0])
razor객체는 Options 인터페이스를 구현 IgbGridStateOptions 합니다, 즉 특정 기능의 이름인 모든 키에 대해 이 기능 상태가 추적되는지 여부를 나타내는 부울 값이 있습니다. GetStateAsStringAsync 메서드는 이러한 기능의 상태를 반환된 값에 넣지 않으며 ApplyStateFromStringAsync 메서드는 해당 기능의 상태를 복원하지 않습니다.
gridState.Options = new IgbGridStateOptions
{
CellSelection = false,
Sorting = false
};
razor사용하기 쉬운 단일 지점 API를 사용하면 몇 줄의 코드로 전체 상태 유지 기능을 얻을 수 있습니다. 아래에서 코드를 복사하여 붙여 넣 으십시오 - 사용자가 현재 페이지를 떠날 때마다 브라우저 LocalStorage 개체에 그리드 상태를 저장합니다. 사용자가 기본 페이지로 돌아갈 때마다 그리드 상태가 복원됩니다. 더 이상 원하는 데이터를 얻기 위해 매번 복잡한 고급 필터링 및 정렬 표현식을 구성할 필요가 없습니다 - 한 번만 수행하고 아래 코드가 사용자를 위해 나머지 작업을 수행하도록 합니다.

Limitations
GetStateAsString메서드는 JSON.stringify() 메서드를 사용하여 원본 객체를 JSON 문자열로 변환합니다. JSON.stringify()는 함수를 지원하지 않으므로IgbGridState구성 요소가 열,,,,CellClasses SortStrategy,Filters Summaries및BodyTemplate HeaderTemplate CellStyles속성을 무시합니다.Formatter
