Grid Row Height

By default the Grid displays all rows with a height of 30px. It is defined by the --smart-grid-row-height CSS variable i.e you can change the row height by setting a new value to this variable. It is possible to change the row height by setting the layout.rowHeight property, too.

Example:

const gridOptions = {
    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: 'Anthony',
            lastName: 'Baker',
            product: {
                name: 'Frappucino', price: 6, quantity: 4, total: 24
            }
        }
    ],
    layout: {
        rowHeight: 50
    },
    columns: [
        {
            label: 'First Name', dataField: 'firstName', cellsVerticalAlign: 'center'
        },
        { label: 'Last Name', dataField: 'lastName' },
        { label: 'Product', dataField: 'productName' },
        {
            label: 'Quantity', dataField: 'quantity', cellsAlign: 'right'
        },
        { label: 'Unit Price', dataField: 'price', cellsAlign: 'right', cellsFormat: 'c2' }
    ]
}
	

Custom Row Height

Each row may have a different row height. You can use the row.height property to set a new height to the row. In the following example, we will show how to set a row height, during the row initialization process.

const gridOptions = {
    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: 'Anthony',
            lastName: 'Baker',
            product: {
                name: 'Frappucino', price: 6, quantity: 4, total: 24
            }
        }
    ],
    onRowInit: (index, row) => {
        if (index === 0) {
            row.height = 35;
        }
        else if (index === 1) {
            row.height = 50;
        }
        else if (index === 2) {
            row.height = 80;
        }
        else row.height = 50;
    },
    columns: [
        {
            label: 'First Name', dataField: 'firstName', cellsVerticalAlign: 'center'
        },
        { label: 'Last Name', dataField: 'lastName' },
        { label: 'Product', dataField: 'productName' },
        {
            label: 'Quantity', dataField: 'quantity', cellsAlign: 'right'
        },
        { label: 'Unit Price', dataField: 'price', cellsAlign: 'right', cellsFormat: 'c2' }
    ]
}
	

Cells Text Wrapping and auto row height

By setting the layout.rowHeight property to 'auto' and layout.allowCellsWrap property to true, the text inside rows will wrap and the rows will auto-resize.

	layout: {
        allowCellsWrap: true,
        rowHeight: 'auto'
    }
	

Row Resize

To enable row resize, you will need to set the behavior.rowResizeMode to 'growAndShrink' or 'split' and the appearance.showRowHeader property to true.
