Grid Row Sorting

Enable Sorting

Grid sorting by single column is enabled by setting the sorting.enabled property to true. You can then sort a column by clicking on the column header.

componentProps = {
    dataSourceSettings: {
        dataFields: [
            { name: 'firstName', dataType: 'string' },
            { name: 'lastName', dataType: 'string' },
            { name: 'productName', map: 'product.name', dataType: 'string' },
            { name: 'quantity', map: 'product.quantity', dataType: 'number' },
            { name: 'price', map: 'product.price', dataType: 'number' },
            { name: 'total', map: 'product.total', dataType: 'number' }
        ]
    },
    behavior: {
        columnResizeMode: 'growAndShrink'
    },
    sorting: {
        enabled: true
    },
    dataSource: [
        {
            firstName: 'Andrew',
            lastName: 'Burke',
            product: {
                name: 'Ice Coffee', price: 10, quantity: 3, total: 30
            }
        },
        {
            firstName: 'Petra',
            lastName: 'Williams',
            product: {
                name: 'Espresso', price: 7, quantity: 5, total: 35
            }
        },
        {
            firstName: 'Kevin',
            lastName: 'Baker',
            product: {
                name: 'Frappucino', price: 6, quantity: 4, total: 24
            }
        }
    ],
    columns: [
        { label: 'First Name', dataField: 'firstName', allowSort: false },
        { label: 'Last Name', dataField: 'lastName' },
        { label: 'Product', dataField: 'productName' },
        { label: 'Quantity', dataField: 'quantity', cellsAlign: 'right' },
        { label: 'Unit Price', dataField: 'price', cellsAlign: 'right', cellsFormat: 'c2' }
    ]
}

Disable Column Sorting

Disable sorting for columns by setting the allowSort column definition to false.

Sort Column when you create the Grid

You can use the sorting.sort property. The property expects an Array with key-value pairs. The key is the column's dataField, the value is the sort order - 'asc' or 'desc'.

sorting: {
	enabled: true,
	sort: [
		{ 'lastName': 'asc' }
	]
}

Sort Multiple Columns

It is possible to sort by multiple columns

sorting: {
	enabled: true,
	mode: 'many',
	sort: [
		{ 'lastName': 'asc' },
		{ 'productName': 'desc' }
	]
}

If you want to sort by multiple columns only while you hold the 'Control' key, you can set the sorting.commandKey property to Control.

sorting: {
	enabled: true,
	mode: 'many',
	commandKey: 'Control',
	sort: [
		{ 'lastName': 'asc' },
		{ 'productName': 'desc' }
	]
}

Clear Sorting API

To clear the sorting, you can use the clearSort() method.

this.grid.clearSort();

Sort by Column API

To sort by a column, you can use the sortBy(dataField, sortOrder) method.

this.grid.sortBy('productName', 'desc');

Custom Sort

Custom sorting can be configured by using the column's sortComparator(value1, value2) function.
Example:

componentProps = {
    dataSourceSettings: {
        dataFields: [
            { name: 'firstName', dataType: 'string' },
            { name: 'lastName', dataType: 'string' },
            { name: 'productName', map: 'product.name', dataType: 'string' },
            { name: 'quantity', map: 'product.quantity', dataType: 'number' },
            { name: 'price', map: 'product.price', dataType: 'number' },
            { name: 'total', map: 'product.total', dataType: 'number' }
        ]
    },
    behavior: {
        columnResizeMode: 'growAndShrink'
    },
    sorting: {
        enabled: true
    },
    dataSource: [
        {
            firstName: 'Andrew',
            lastName: 'Burke',
            product: {
                name: 'Ice Coffee', price: 10, quantity: 3, total: 30
            }
        },
        {
            firstName: 'Petra',
            lastName: 'Williams',
            product: {
                name: 'Espresso', price: 7, quantity: 5, total: 35
            }
        },
        {
            firstName: 'Kevin',
            lastName: 'Baker',
            product: {
                name: 'Frappucino', price: 6, quantity: 4, total: 24
            }
        }
    ],
    columns: [
		{ label: 'First Name', dataField: 'firstName' },
		{ label: 'Last Name', dataField: 'lastName' },
		{ label: 'Product', dataField: 'productName' },
		{
			label: 'Quantity', dataField: 'quantity', cellsAlign: 'right', sortOrder: 'asc', 
			sortComparator: (value1, value2) => {
				const result = value1 === value2;

				// When the value is 4, it will bubble up.
				if (value1 === 4) {
					return -1;
				}

				if (value2 === 4) {
					return 1;
				}

				// return 0 for equal values.
				if (result) {
					return 0;
				}

				// return -1, if value1 is smaller than value2.
				if (value1 < value2) {
					return -1;
				}

				// return 1, if value1 is greater than value2.
				return 1;
			}
		},
		{ label: 'Unit Price', dataField: 'price', cellsAlign: 'right', cellsFormat: 'c2' }
    ]
