Setup

​IgbTreeGrid 및 축소 가능한 다중 열 헤더 기능을 시작하려면 먼저 다음 명령을 입력하여 Ignite UI for Blazor 설치해야 합니다.

> dotnet add package IgniteUI.Blazor --version 24.2.85
cmd

Ignite UI for Blazor에 대한 전체 소개를 보려면 시작하기 항목을 읽어보세요.

또한 그리드에서 열 그룹을 설정하는 방법에 대한 자세한 내용을 보려면 다중 열 헤더 항목을 간략하게 살펴보는 것이 좋습니다.

Usage

축소 가능한 열 그룹은 열 그룹을 더 작은 데이터 세트로 축소/확장하는 방법을 제공하는 다중 열 헤더 기능의 일부입니다. 열 그룹이 축소되면 열의 하위 집합이 최종 사용자에게 표시되고 그룹의 다른 하위 열은 숨겨집니다. 축소/확장된 각 열은 그리드 데이터 소스에 바인딩되거나 바인딩 해제되어 계산될 수 있습니다.

열 그룹을 접을 수 있도록 정의하려면 다음을 설정해야 합니다. Collapsible의 재산 IgbColumnGroup에게 진실.

​VisibleWhenCollapsed 속성을 두 개 이상의 하위 열에 정의해야 합니다. 그룹이 축소될 때(VisibleWhenCollapsed​ ​true로 설정됨) 하나 이상의 열이 표시되어야 하고, 그룹이 확장될 때(VisibleWhenCollapsed가 false로 설정됨) 하나 이상의 열이 숨겨져야 합니다. 그렇지 않으면 축소 가능 기능이 비활성화됩니다. 일부 하위 열에 대해 VisibleWhenCollapsed 지정되지 않은 경우 상위 상태가 확장되거나 축소되었는지 여부에 관계없이 이 열이 항상 표시됩니다.

아래 마크업을 살펴보겠습니다.

 <IgbColumnGroup Header="Customer Information" Collapsible="true">
    <!--The column below will be visible when its parent is collapsed-->
    <IgbColumn Field="CustomerName" Header="Full name" VisibleWhenCollapsed="true"></IgbColumn>
        <!--The three columns below will be visible when its parent is expanded-->
        <IgbColumn Field="CustomerID" Header="Customer ID" VisibleWhenCollapsed="false"></IgbColumn>
        <IgbColumn Field="FirstName" Header="First Name" VisibleWhenCollapsed="false"></IgbColumn>
        <IgbColumn Field="LastName" Header="Last Name" VisibleWhenCollapsed="false"></IgbColumn>
        <IgbColumnGroup Header="Customer Address">
            <IgbColumn Field="Country" Header="Country" Sortable="true"></IgbColumn>
            <IgbColumn Field="City" Header="City" Sortable="true"></IgbColumn>
        </IgbColumnGroup>
 </IgbColumnGroup>
razor

요약하면 모든 하위 열에는 세 가지 상태가 있습니다.

• 상위 항목의 확장 상태에 관계없이 항상 표시될 수 있습니다.
• 상위 항목이 축소되면 표시될 수 있습니다.
• 상위 항목이 축소되면 숨길 수 있습니다.

축소 가능으로 지정된 열 그룹의 초기 상태는 다음과 같습니다. Expanded로 설정 진실로 설정하여 이 동작을 쉽게 변경할 수 있습니다. 거짓.

참고 초기에 그룹 축소 옵션은 열 숨김보다 우선합니다. 숨김 속성을 사용하여 열을 숨기도록 선언하고 동일한 열이 표시되어야 하는 그룹을 정의한 경우 해당 열이 표시됩니다.
