React Grid Sorting

The Ignite UI for React Data Sorting feature in React Grid is enabled on a per-column level, meaning that the IgrGrid can have a mix of sortable and non-sortable columns. Performing React sort actions enables you to change the display order of the records based on specified criteria.

React Grid Sorting Overview Example

This is done via the sortable input. With the IgrGrid sorting, you can also set the sortingIgnoreCase property to perform case sensitive sorting:

<IgrColumn field="ProductName" header="Product Name" dataType="string" sortable={true}></IgrColumn>

Indicadores de clasificación

Tener una cierta cantidad de columnas ordenadas puede resultar realmente confuso si no hay ninguna indicación del orden de clasificación.

The IgrGrid provides a solution for this problem by indicating the index of each sorted column.

Ordenando a través de la API

You can sort any column or a combination of columns through the IgrGrid API using the IgrGrid sort method:

import { SortingDirection } from "igniteui-react-grids";

// Perform a case insensitive ascending sort on the ProductName column.
gridRef.current.sort([{ fieldName: 'ProductName', dir: SortingDirection.Asc, ignoreCase: true }]);

// Perform sorting on both the ProductName and Price columns.
gridRef.current.sort([
    { fieldName: 'ProductName', dir: SortingDirection.Asc, ignoreCase: true },
    { fieldName: 'Price', dir: SortingDirection.Desc }
]);

[!Note] Sorting is performed using our DefaultSortingStrategy algorithm. Any IgrColumn or ISortingExpression can use a custom implementation of the ISortingStrategy as a substitute algorithm. This is useful when custom sorting needs to be defined for complex template columns, or image columns, for example.

As with the filtering behavior, you can clear the sorting state by using the clearSort method:

// Removes the sorting state from the ProductName column
gridRef.current.clearSort('ProductName');

// Removes the sorting state from every column in the Grid
gridRef.current.clearSort();

[!Note] The sortStrategy of the IgrGrid is of different type compared to the sortStrategy of the IgrColumn, since they work in different scopes and expose different parameters.

[!Note] The sorting operation DOES NOT change the underlying data source of the IgrGrid.

Estado de ordenación inicial

It is possible to set the initial sorting state of the IgrGrid by passing an array of sorting expressions to the sortingExpressions property of the IgrGrid.

const sortingExpressions: IgrSortingExpression[] = [
    { fieldName: 'UnitsInStock', dir: SortingDirection.Asc, ignoreCase: true },
    { fieldName: 'ProductName', dir: SortingDirection.Desc }
];

<IgrGrid
    data={productSales}
    sortingExpressions={sortingExpressions}>
</IgrGrid>

[!Note] If values of type string are used by a column of dataType Date, the IgrGrid won't parse them to Date objects and using IgrGrid Sorting won't work as expected. If you want to use string objects, additional logic should be implemented on an application level, in order to parse the values to Date objects.

Plantillas de indicadores de clasificación

El icono del indicador de clasificación en el encabezado de la columna se puede personalizar mediante una plantilla. Las siguientes propiedades están disponibles para crear plantillas del indicador de clasificación para cualquier estado de clasificación (ascendente, descendente, ninguno):

sortHeaderIconTemplate – re-templates the sorting icon when no sorting is applied.

const sortHeaderIconTemplate = (ctx: IgrGridHeaderTemplateContext) => {
    return (
        <>
            <IgrIcon name='unfold_more'></IgrIcon>
        </>
    );
}

<IgrGrid sortHeaderIconTemplate={sortHeaderIconTemplate}></IgrGrid>

sortAscendingHeaderIconTemplate – re-templates the sorting icon when the column is sorted in ascending order.

const sortAscendingHeaderIconTemplate = (ctx: IgrGridHeaderTemplateContext) => {
    return (
        <>
            <IgrIcon name='expand_less'></IgrIcon>
        </>
    );
}

<IgrGrid sortAscendingHeaderIconTemplate={sortAscendingHeaderIconTemplate}></IgrGrid>

sortDescendingHeaderIconTemplate – re-templates the sorting icon when the column is sorted in descending order.

const sortDescendingHeaderIconTemplate = (ctx: IgrGridHeaderTemplateContext) => {
    return (
        <>
            <IgrIcon name='expand_more'></IgrIcon>
        </>
    );
}

<IgrGrid sortDescendingHeaderIconTemplate={sortDescendingHeaderIconTemplate}></IgrGrid>

Estilismo

Además de los temas predefinidos, la cuadrícula se puede personalizar aún más configurando algunas de las propiedades CSS disponibles. En caso de que desee cambiar algunos de los colores, primero debe establecer una clase para la cuadrícula:

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

Luego establezca las propiedades CSS relacionadas con esta clase:

.grid {
    --ig-grid-sorted-header-icon-color: #ffb06a;
    --ig-grid-sortable-header-icon-hover-color: black;
}
