Blazor Tree Grid Summaries

Blazor Tree Grid의 Ignite UI for Blazor는 그룹 푸터로 열 단위로 작동합니다. Blazor TreeGrid 요약은 사용자가 열 내 데이터 유형에 따라 또는 IgbTreeGrid에서 사용자 정의 템플릿을 구현하여 사전 정의된 기본 요약 항목 세트가 있는 별도의 컨테이너에서 열 정보를 볼 수 있도록 하는 강력한 기능입니다.

The summary of the column is a function of all column values, unless filtering is applied, then the summary of the column will be function of the filtered result values

IgbTreeGrid 요약은 Ignite UI for Blazor에서 열 단위로 활성화할 수도 있습니다. 즉, 필요한 열에 대해서만 활성화할 수 있습니다. IgbTreeGrid 요약은 열의 데이터 유형에 따라 미리 정의된 기본 요약 세트를 제공하므로 시간을 절약할 수 있습니다.

string 및 boolean DataType의 경우 다음 함수를 사용할 수 있습니다.

number, currency 및 percent 데이터 유형의 경우 다음 함수를 사용할 수 있습니다.

사용 가능한 모든 열 데이터 유형은 공식 열 유형 항목에서 찾을 수 있습니다.

IgbTreeGrid 요약은 설정을 통해 열별로 사용할 수 있습니다. HasSummary 속성을 참. 또한 각 열에 대한 요약은 열 데이터 형식에 따라 확인된다는 점을 명심해야 합니다. 안에 IgbTreeGrid 기본 열 데이터 형식은 string, 그래서 당신이 원한다면 number 또는 date 특정 요약을 지정해야 합니다. DataType 속성을 number 또는 date. 요약 값은 그리드에 따라 지역화되어 표시됩니다 Locale 및 열 PipeArgs.

Custom Tree Grid Summaries

이러한 기능이 요구 사항을 충족하지 못하는 경우 특정 열에 대한 사용자 정의 요약을 제공할 수 있습니다.


//In JavaScript
class PtoSummary {
    operate(data, allData, fieldName) {
        const result = [];
        result.push({
            key: 'totalOnPTO',
            label: 'Employees On PTO',
            summaryResult: this.count(allData.filter((rec) => rec['OnPTO']).map(r => r[fieldName]))
        });
        result.push({
            key: 'devs',
            label: 'Developers',
            summaryResult: this.count(allData.filter((rec) => rec[fieldName].includes('Developer') && rec['OnPTO']).map(r => r[fieldName]))
        });
        result.push({
            key: 'tl',
            label: 'Team Leads',
            summaryResult: this.count(allData.filter((rec) => rec[fieldName].includes('Team Lead') && rec['OnPTO']).map(r => r[fieldName]))
        });
        result.push({
            key: 'managers',
            label: 'Managers/Directors',
            summaryResult: this.count(allData.filter((rec) => (rec[fieldName].includes('Manager') || rec[fieldName].includes('Director')) && rec['OnPTO']).map(r => r[fieldName]))
        });
        result.push({
            key: 'ceo',
            label: 'CEO/President',
            summaryResult: this.count(allData.filter((rec) => (rec[fieldName].includes('CEO') || rec[fieldName].includes('President')) && rec['OnPTO']).map(r => r[fieldName]))
        });
        return result;
    }
}
razor

예제에서 볼 수 있듯이 기본 클래스는 Operate 메서드를 노출하므로 모든 기본 요약을 가져오고 결과를 수정하거나 완전히 새로운 요약 결과를 계산하도록 선택할 수 있습니다.

이 메소드는 IgbSummaryResult 목록을 반환합니다.

요약을 계산하기 위해 선택적 매개변수를 사용합니다. 아래의 모든 데이터 섹션에 액세스하는 사용자 정의 요약을 참조하세요.

In order to calculate the summary row height properly, the Tree Grid needs the Operate method to always return an array of IgbSummaryResult with the proper length even when the data is empty.

<IgbTreeGrid 
        AutoGenerate="true"
        Name="treeGrid"
        @ref="treeGrid"
        Data="EmployeesFlatData"
        PrimaryKey="ID"
        ColumnInitScript="WebTreeGridCustomSummary">
</IgbTreeGrid>

// In Javascript
igRegisterScript("WebTreeGridCustomSummary", (event) => {
    if (event.detail.field === "Title") {
        event.detail.summaries = PtoSummary;
    }
}, false);
razor

Custom summaries, which access all data

이제 사용자 지정 열 요약 내의 모든 트리 그리드 데이터에 액세스할 수 있습니다. SummaryOperand 메서드에는 두 개의 추가 선택적 매개 변수가 도입되었습니다 Operate. 아래 코드 스니펫에서 볼 수 있듯이 operation 메서드에는 다음 세 가지 매개 변수가 있습니다.

columnData - 현재 열의 값만 포함하는 배열을 제공합니다.
allGridData - 전체 그리드 데이터 소스를 제공합니다.
fieldName - 현재 열 필드

Summary Template

Summary 열 요약 결과를 컨텍스트로 제공하는 열 요약을 대상으로 합니다.

<IgbColumn HasSummary="true" SummaryTemplateScript="SummaryTemplate">
</IgbColumn>

igRegisterScript("SummaryTemplate", (ctx) => {
    var html = window.igTemplating.html;
    return html`<div>
    <span> ${ctx.implicit[0].label} - ${ctx.implicit[0].summaryResult} </span>
</div>`
}, false);
razor

기본 요약이 정의되면 요약 영역의 높이는 요약 수가 가장 많은 열과--ig-size 그리드에 따라 설계에 따라 계산됩니다. SummaryRowHeight input 속성을 사용하여 기본값을 재정의합니다. 인수로 숫자 값이 필요하며 거짓 값을 설정하면 그리드 바닥글의 기본 크기 조정 동작이 트리거됩니다.

Disabled Summaries

이 DisabledSummaries 속성은 Blazor Tree Grid 요약 기능에 대한 열별 정확한 제어를 제공합니다. 이 속성을 사용하면 사용자가 TreeGrid의 각 열에 대해 표시되는 요약을 사용자 지정하여 가장 관련성이 높고 의미 있는 데이터만 표시되도록 할 수 있습니다. 예를 들어, 배열에서 요약 키를 지정하는 것과 같이 ['count', 'min', 'max'] 특정 요약 유형을 제외할 수 있습니다.

또한 이 속성은 코드를 통해 런타임에 동적으로 수정할 수 있으므로 변화하는 애플리케이션 상태 또는 사용자 작업에 맞게 TreeGrid의 요약을 조정할 수 있는 유연성을 제공합니다.

다음 예제에서는 속성을 사용하여 DisabledSummaries 다른 열에 대한 요약을 관리하고 Blazor 트리 그리드에서 특정 기본 및 사용자 지정 요약 유형을 제외하는 방법을 보여 줍니다.

<!-- Disable default summaries -->
<IgbColumn 
    Field="UnitPrice" 
    Header="Unit Price" 
    DataType="GridColumnDataType.Number"
    HasSummary="true" 
    DisabledSummaries="['count', 'sum', 'average']" />

<!-- Disable custom summaries -->
<IgbColumn 
    Field="UnitsInStock" 
    Header="Units In Stock" 
    DataType="GridColumnDataType.Number"
    HasSummary="true" 
    Summaries="discontinuedSummary" 
    DisabledSummaries="['discontinued', 'totalDiscontinued']" />
razor

의 UnitPrice 경우, 기본 요약은 , sum와 average 같고 count 비활성화되어 있으며 다른 요약은 같고 min max 활성 상태로 유지됩니다.

의 경우 UnitsInStock, 및 totalDiscontinued와 같은 discontinued 사용자 지정 요약은 DisabledSummaries 속성을 사용하여 제외됩니다.

런타임에는 속성을 사용하여 요약을 동적으로 비활성화할 수도 있습니다 DisabledSummaries. 예를 들어 프로그래밍 방식으로 특정 열의 속성을 설정하거나 업데이트하여 사용자 작업 또는 응용 프로그램 상태 변경에 따라 표시되는 요약을 조정할 수 있습니다.

Child Summaries

루트 노드와 각 중첩된 자식 노드 수준에 대해 별도의 요약을 IgbTreeGrid 지원합니다. 표시되는 요약은 속성을 사용하여 구성할 수 있습니다 SummaryCalculationMode. 자식 수준 요약은 SummaryPosition 속성을 사용하여 자식 노드 앞이나 뒤에 표시할 수 있습니다. 이러한 두 속성 IgbTreeGrid과 함께 노출 및 ShowSummaryOnCollapse 속성을 사용하면 참조하는 부모 노드가 축소될 때 요약 행이 계속 표시되는지 여부를 결정할 수 있습니다.

SummaryCalculationMode 속성의 사용 가능한 값은 다음과 같습니다.

RootLevelOnly- 요약은 루트 수준 노드에 대해서만 계산됩니다.
ChildLevelsOnly- 요약은 하위 수준에 대해서만 계산됩니다.
RootAndChildLevels- 루트 및 하위 수준 모두에 대한 요약이 계산됩니다. 이것이 기본값입니다.

SummaryPosition 속성의 사용 가능한 값은 다음과 같습니다.

Top- 요약 행은 하위 행 목록 앞에 나타납니다.
Bottom- 요약 행은 하위 행 목록 뒤에 나타납니다. 이 값은 기본값입니다.

ShowSummaryOnCollapse 속성은 부울입니다. 기본값은 false로 설정되며, 이는 부모 행이 축소될 때 요약 행이 숨겨진다는 것을 의미합니다. 속성이 true로 설정된 경우 부모 행이 축소될 때 요약 행이 계속 표시됩니다.

The SummaryPosition property applies only for the child level summaries. The root level summaries appear always fixed at the bottom of the IgbTreeGrid.

요약 행은 다음 키보드 상호 작용을 통해 탐색할 수 있습니다.

UP- 한 셀 위로 이동합니다.
DOWN- 한 셀 아래로 이동합니다.
왼쪽- 한 셀 왼쪽으로 이동합니다.
RIGHT- 한 셀 오른쪽으로 이동합니다.
CTRL + LEFT 또는 HOME- 가장 왼쪽 셀로 이동합니다.
CTRL + RIGHT 또는 END- 가장 오른쪽 셀로 이동합니다.

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="grid"></IgbTreeGrid>
razor

그런 다음 해당 클래스에 대한 관련 CSS 속성을 설정합니다.

.grid {
    --ig-grid-summary-background-color:#e0f3ff;
    --ig-grid-summary-focus-background-color: rgba( #94d1f7, .3 );
    --ig-grid-summary-label-color: rgb(228, 27, 117);
    --ig-grid-summary-result-color: black;
