Blazor 트리 그리드 셀 선택
Blazor Tree Grid의 Ignite UI for Blazor 풍부한 데이터 선택 기능을 제공하고 IgbTreeGrid 구성 요소에서 강력한 API를 제공합니다. Blazor Tree Grid는 세 가지 선택 모드를 지원합니다.
- 트리 그리드 다중 셀 선택
- Tree Grid Single Selection
- 트리 그리드 없음 선택
각 옵션에 대해 자세히 알아보겠습니다.
Blazor Tree Grid Cell Selection Example
아래 샘플은 IgbTreeGrid의 셀 선택 동작의 세 가지 유형을 보여줍니다. 아래 버튼을 사용하여 사용 가능한 각 선택 모드를 활성화합니다. 스낵바 메시지 상자를 통해 각 버튼 상호작용에 대한 간략한 설명이 제공됩니다.

Selection Types
Tree Grid Multiple-Cell Selection
셀을 선택하는 방법:
- 마우스 드래그- 셀의 직사각형 데이터 선택이 수행됩니다.
- Ctrl 키 누르기 + 마우스 끌기- 여러 범위 선택이 수행됩니다. 다른 기존 셀 선택은 유지됩니다.
- Shift 키를 사용하여 즉시 다중 셀 선택. 단일 셀을 선택하고 Shift 키를 누른 채 다른 단일 셀을 선택합니다. 두 셀 사이의 셀 범위가 선택됩니다. Shift 키를 누른 상태에서 다른 두 번째 셀을 선택하면 셀 선택 범위는 처음 선택한 셀 위치(시작점)를 기준으로 업데이트됩니다.
- Shift 키를 누른 상태에서 화살표 키를 사용하여 키보드 다중 셀 선택. 선택된 셀을 기준으로 다중 셀 선택 범위가 생성됩니다.
- Shift 키를 누른 상태에서 Ctrl + ↑ ↓ ← → 키와 Ctrl + Home / End를 사용하여 키보드 다중 셀 선택. 선택된 셀을 기준으로 다중 셀 선택 범위가 생성됩니다.
- 로 클릭하면 마우스 왼쪽 키를 누른 상태에서 Ctrl 키 키는 선택한 셀 컬렉션에 단일 셀 범위를 추가합니다.
- 마우스로 클릭하고 드래그하면 연속적인 다중 셀 선택이 가능합니다.

Tree Grid Single Selection
CellSelection Single로 설정하면 그리드에서 한 번에 하나의 셀만 선택할 수 있습니다. 또한 모드 마우스 끌기는 작동하지 않으며 셀을 선택하는 대신 기본 텍스트 선택이 됩니다.
단일 셀을 선택한 경우
Selected이벤트가 발생합니다. 선택 모드 ~이다 하나의 또는 다수의. 다중 셀 선택 모드에서 셀 범위를 선택할 때RangeSelected이벤트가 방출됩니다.
트리 그리드 없음 선택
셀 선택을 비활성화하려면 CellSelection none으로 설정하면 됩니다. 이 모드에서 셀을 클릭하거나 키보드로 탐색하려고 하면 셀이 선택되지 않고 활성화 스타일만 적용되며 페이지의 다른 요소를 스크롤하거나 클릭하면 셀이 손실됩니다. 선택을 정의하는 유일한 방법은 아래에 설명된 API 메서드를 사용하는 것입니다.
Keyboard Navigation Interactions
While Shift Key is Pressed
- 현재 선택 항목에 위 셀을 추가하려면 Shift + ↑를 누르세요.
- 현재 선택 항목에 아래 셀을 추가하려면 Shift + ↓를 누르세요.
- 현재 선택 항목에 왼쪽 셀을 추가하려면 Shift + ←를 누르세요.
- Shift + → 현재 선택 항목에 오른쪽 셀을 추가합니다.
While Ctrl + Shift Keys are Pressed
- Ctrl + Shift + ↑를 사용하면 열에서 초점이 맞춰진 셀 위의 모든 셀을 선택할 수 있습니다.
- Ctrl + Shift + ↓를 눌러 열에서 초점이 맞춰진 셀 아래의 모든 셀을 선택합니다.
- Ctrl + Shift + ←를 누르면 행 시작 부분까지 모든 셀을 선택합니다.
- Ctrl + Shift + → 행 끝까지의 모든 셀을 선택합니다.
- Ctrl + Shift + Home: 초점이 맞춰진 셀부터 그리드의 첫 번째 셀까지 모든 셀을 선택합니다.
- Ctrl + Shift + End -초점이 맞춰진 셀부터 그리드의 마지막 셀까지 모든 셀을 선택합니다.
Continuous scroll is possible only within Grid's body.
Api Usage
다음은 범위를 선택하거나, 선택 항목을 지우거나, 선택한 셀 데이터를 가져오는 데 사용할 수 있는 방법입니다.
Select range
SelectRange- API를 사용하여 셀 범위를 선택합니다. rowStart 및 rowEnd는 행 인덱스를 사용해야 하며 columnStart 및 columnEnd는 열 인덱스 또는 열 데이터 필드 값을 사용할 수 있습니다.
<IgbTreeGrid @ref=grid CellSelection="GridSelectionMode.Multiple" AutoGenerate=true></<IgbTreeGrid>
@code {
private IgbTreeGrid grid;
private async void SetSelection()
{
IgbGridSelectionRange selectionRange = new IgbGridSelectionRange();
selectionRange.ColumnStart = 1;
selectionRange.ColumnEnd = 1;
selectionRange.RowStart = 2;
selectionRange.RowEnd = 2;
this.grid.SelectRange(new IgbGridSelectionRange[] {});
}
}
razorClear cell selection
ClearCellSelection 현재 셀 선택을 지웁니다.
@code {
private async void ClearSelection()
{
await this.grid.ClearCellSelectionAsync();
}
}
razorGet Selected Data
GetSelectedData 선택한 데이터의 배열을 사전 형식으로 반환합니다. 아래 예:
<IgbTreeGrid @ref=grid CellSelection="GridSelectionMode.Multiple" AutoGenerate=true></<IgbTreeGrid>
@code {
private IgbTreeGrid grid;
private async void GetSelectedData()
{
object[] data = await this.grid.GetSelectedDataAsync(true, true);
}
}
razorFeatures Integration
다중 셀 선택은 인덱스 기반입니다(DOM 요소 선택).
Sorting- 정렬이 수행되면 선택이 지워지지 않습니다. 오름차순 또는 내림차순으로 정렬하는 동안 현재 선택된 셀은 동일하게 유지됩니다.Paging- 페이징 시 선택한 셀이 지워집니다. 선택 항목은 여러 페이지에 걸쳐 유지되지 않습니다.Filtering- 필터링이 수행되면 선택이 지워지지 않습니다. 필터링이 지워지면 처음에 선택한 셀이 반환됩니다.Resizing- 열 크기 조정 시 선택한 셀이 지워지지 않습니다.Hiding- 선택한 셀을 지우지 않습니다. 열이 숨겨져 있으면 표시되는 다음 열의 셀이 선택됩니다.Pinning- 선택한 셀이 지워지지 않습니다. 숨기는 것도 마찬가지GroupBy- 열 그룹화 시 선택한 셀이 지워지지 않습니다.
Styling
사전 정의된 테마 외에도 사용 가능한 CSS 속성 중 일부를 설정하여 그리드를 추가로 사용자 정의할 수 있습니다. 일부 색상을 변경하려면 먼저 그리드에 대한 클래스를 설정해야 합니다.
<IgbTreeGrid Class="treeGrid"></IgbTreeGrid>
razor그런 다음 해당 클래스에 대한 관련 CSS 속성을 설정합니다.
.treeGrid {
--ig-grid-cell-selected-text-color: #fff;
--ig-grid-cell-active-border-color: #f2c43c;
--ig-grid-cell-selected-background: #0062a3;
