Reordenação e movimentação de colunas da grade

    O recurso React Grid Column Moving no Ignite UI for React permite a reordenação rápida e fácil da coluna. Isso pode ser feito por meio da API de movimentação de colunas ou arrastando e soltando os cabeçalhos em outra posição por meio de gestos de mouse ou toque. Na grade React, você pode habilitar a movimentação de coluna para colunas fixadas e não fixadas e também para cabeçalhos de várias colunas.

    [!Note] Reordering between columns and column groups is allowed only when they are at the same level in the hierarchy and both are in the same group. Moving is allowed between columns/column-groups, if they are top level columns.

    [!Note] If a column header is templated and the Column Moving is enabled or the corresponding column is groupable, then the templated elements need to have the draggable attribute set to false!

    [!Note] If the pinned area exceeds its maximum allowed width (80% of the total IgrGrid width), a visual clue notifies the end user that the drop operation is forbidden and pinning is not possible. This means you won't be allowed to drop a column in the pinned area.

    const headerTemplate = (ctx: IgrCellTemplateContext) => {
    return (
    <>
       <IgrIcon draggable={false} onClick={onClick}></IgrIcon>
    </>
    );
}

    React Grid Column Moving Overview Example

    Visão geral

    Column moving feature is enabled on a per-grid level, meaning that the IgrGrid could have either movable or immovable columns. This is done via the moving input of the IgrGrid.

    <IgrGrid moving={true}></IgrGrid>

    API

    Além da funcionalidade de arrastar e soltar, o recurso Column Moving também fornece métodos de API para permitir mover uma coluna/reordenar colunas programaticamente:

    moveColumn - Moves a column before or after another column (a target). The first parameter is the column to be moved, and the second parameter is the target column. Also accepts an optional third parameter Position (representing a DropPosition value), which determines whether to place the column before or after the target column.

    // Move the ID column after the Name column
const idColumn = grid.getColumnByName("ID");
const nameColumn = grid.getColumnByName("Name");

grid.moveColumn(idColumn, nameColumn, DropPosition.AfterDropTarget);

    move - Moves a column to a specified visible index. If the passed index parameter is invalid (is negative, or exceeds the number of columns), or if the column is not allowed to move to this index (if inside another group), no operation is performed.

    // Move the ID column at 3rd position.
const idColumn = grid.getColumnByName("ID");
idColumn.move(3);

    Note that when using the column moving feature, the ColumnMovingEnd event will be emitted if the operation was successful. Also note that in comparison to the drag and drop functionality, using the column moving feature does not require setting the moving property to true.

    Eventos

    There are several events related to the column moving to provide a means for tapping into the columns' drag and drop operations. These are ColumnMovingStart, ColumnMoving and ColumnMovingEnd.

    You can subscribe to the ColumnMovingEnd event of the IgrGrid to implement some custom logic when a column is dropped to a new position. For example, you can cancel dropping the Category column after the Change On Year(%) column in the following code snippet.

    const onColumnMovingEnd = (event: IgrColumnMovingEndEventArgs) => {
   if (event.detail.source.field === "Category" && event.detail.target.field === "Change On Year(%)") {
        event.detail.cancel = true;
    }
}

<IgrGrid autoGenerate={false} moving={true} data={data} onColumnMovingEnd={onColumnMovingEnd}>
    <IgrColumn field="Category"></IgrColumn>
    <IgrColumn field="Change On Year(%)" dataType="number"></IgrColumn>
</IgrGrid>

    Styling

    Além dos temas predefinidos, a grade pode ser ainda mais personalizada definindo algumas das propriedades CSS disponíveis.

    Caso você queira alterar algumas das cores, você precisa primeiro definir uma classe para a grade:

    <IgrGrid className="grid"></IgrGrid>

    Em seguida, defina as propriedades CSS relacionadas a esta classe:

    .grid {
    --ig-grid-ghost-header-text-color: #f4d45c;
    --ig-grid-ghost-header-background: #ad9d9d;
    --ig-grid-ghost-header-icon-color: #f4d45c;
}
