Configuration

​IgbGrid에 대한 행 드래그를 활성화하려면 그리드의 RowDraggable​ ​true로 설정하기만 하면 됩니다. 이 기능이 활성화되면 행 끌기 핸들이 각 행에 표시됩니다. 이 핸들을 사용하여 행 끌기를 시작할 수 있습니다. 드래그 핸들을 클릭하고 버튼을 누른 채 커서를 움직이면 그리드의 RowDragStart 이벤트가 발생합니다. 언제든지 클릭을 놓으면 RowDragEnd 이벤트가 발생합니다.

<IgbGrid RowDraggable="true">
</IgbGrid>
razor

Templating the Drag Icon

드래그 핸들 아이콘은 그리드의 DragIndicatorIconTemplate 사용하여 템플릿화할 수 있습니다. 우리가 만들고 있는 예제에서 아이콘을 기본 아이콘(drag_indicator)에서 drag_handle로 변경해 보겠습니다.

이를 위해 DragIndicatorIcon 사용하여 IgbGrid 본문 내부에 템플릿을 전달할 수 있습니다.

<IgbGrid Data="CustomersData" PrimaryKey="ID" RowDraggable="true" DragIndicatorIconTemplate="dragIndicatorIconTemplate" @ref="grid">
</IgbGrid>

private RenderFragment<IgbGridEmptyTemplateContext> dragIndicatorIconTemplate = (context) =>
{
    return @<div>
        <IgbIcon IconName="drag_handle" Collection="material"></IgbIcon>
    </div>;
};
razor

Application Demo

Row Reordering Demo

그리드의 행 드래그 이벤트를 사용하면 행을 드래그하여 재정렬할 수 있는 그리드를 생성할 수 있습니다.

<IgbGrid Data="CustomersData" PrimaryKey="ID" RowDraggable="true" RowDragEndScript="WebGridReorderRowHandler"></IgbGrid>

// In JavaScript
igRegisterScript("WebGridReorderRowHandler", (args) => {
    const ghostElement = args.detail.dragDirective.ghostElement;
    const dragElementPos = ghostElement.getBoundingClientRect();
    const grid = document.getElementsByTagName("igc-grid")[0];
    const rows = Array.prototype.slice.call(document.getElementsByTagName("igx-grid-row"));
    const currRowIndex = this.getCurrentRowIndex(rows,
    { x: dragElementPos.x, y: dragElementPos.y });
    if (currRowIndex === -1) { return; }
    // remove the row that was dragged and place it onto its new location
    grid.deleteRow(args.detail.dragData.key);
    grid.data.splice(currRowIndex, 0, args.detail.dragData.data);
}, false);

function getCurrentRowIndex(rowList, cursorPosition) {
    for (const row of rowList) {
        const rowRect = row.getBoundingClientRect();
        if (cursorPosition.y > rowRect.top + window.scrollY && cursorPosition.y < rowRect.bottom + window.scrollY &&
            cursorPosition.x > rowRect.left + window.scrollX && cursorPosition.x < rowRect.right + window.scrollX) {
            // return the index of the targeted row
            return parseInt(row.attributes["data-rowindex"].value);
        }
    }    
    return -1;
}
razor

Make sure that there is a PrimaryKey specified for the grid! The logic needs an unique identifier for the rows so they can be properly reordered.

​RowDraggable 활성화되고 드롭 영역이 정의되면 드롭 이벤트에 대한 간단한 핸들러를 구현해야 합니다. 행을 드래그할 때 다음을 확인하세요.

• 행이 그리드 내부에 삭제되었습니까?
• 그렇다면 드래그된 행이 다른 어느 행에 삭제되었습니까?
• ​대상 행을 찾았으면 Data 배열에서 레코드 위치를 바꿉니다.

아래에서 이것이 구현된 것을 볼 수 있습니다.

이러한 몇 가지 간단한 단계를 통해 드래그/드롭을 통해 행을 재정렬할 수 있는 그리드를 구성했습니다! 다음 데모에서 위 코드가 실제로 작동하는 모습을 볼 수 있습니다.

드래그 아이콘을 누르고 있으면 그리드의 어느 곳으로든 행을 이동할 수 있습니다.
