Active Grid

Sorting - Active Grid

Overview

Sorting allows users to order data by one or multiple columns. The ActiveGrid supports both single-column and multi-column sorting with customizable sort functions.

Basic Usage

Sorting is enabled by default for all columns. Click a column header to sort, click again to reverse, and click a third time to clear sorting.

<ActiveGrid
  columns={columns}
  data={data}
  {...}
/>

Enabling/Disabling Sorting

Globally

Disable sorting for all columns using column defaults:

<ActiveGrid
  columnDefaults={{
    enableSorting: false,
  }}
  {...}
/>

Per Column

Control sorting at the column level:

const columns: GridColumnDef<User>[] = [
  {
    accessorKey: 'name',
    header: 'Name',
    enableSorting: true, // Sortable
  },
  {
    accessorKey: 'id',
    header: 'ID',
    enableSorting: false, // Not sortable
  },
];

Single-Column Sorting

By default, only one column can be sorted at a time. Sorting a new column clears the previous sort.

// Click "Name" header -> sorts by name ascending
// Click "Name" again -> sorts by name descending
// Click "Name" again -> clears sort
// Click "Email" header -> sorts by email, clears name sort

Multi-Column Sorting

Enable multi-column sorting by holding Shift while clicking column headers.

// Click "Name" -> sorts by name
// Shift+Click "Email" -> sorts by name, then email
// Shift+Click "Status" -> sorts by name, then email, then status

The sort order is indicated by numbered badges on sorted columns.

Custom Sort Functions

Basic Custom Sort

{
  accessorKey: 'status',
  header: 'Status',
  sortingFn: (rowA, rowB, columnId) => {
    const statusOrder = ['pending', 'active', 'completed'];
    const valueA = rowA.getValue(columnId) as string;
    const valueB = rowB.getValue(columnId) as string;
    return statusOrder.indexOf(valueA) - statusOrder.indexOf(valueB);
  },
}

Case-Insensitive Text Sort

{
  accessorKey: 'name',
  header: 'Name',
  sortingFn: (rowA, rowB, columnId) => {
    const valueA = (rowA.getValue(columnId) as string).toLowerCase();
    const valueB = (rowB.getValue(columnId) as string).toLowerCase();
    return valueA.localeCompare(valueB);
  },
}

Numeric String Sort

{
  accessorKey: 'orderNumber',
  header: 'Order #',
  sortingFn: (rowA, rowB, columnId) => {
    const numA = parseInt(rowA.getValue(columnId) as string);
    const numB = parseInt(rowB.getValue(columnId) as string);
    return numA - numB;
  },
}

Date Sort

{
  accessorKey: 'createdAt',
  header: 'Created',
  sortingFn: (rowA, rowB, columnId) => {
    const dateA = new Date(rowA.getValue(columnId) as string).getTime();
    const dateB = new Date(rowB.getValue(columnId) as string).getTime();
    return dateA - dateB;
  },
}

Nested Property Sort

{
  accessorKey: 'user',
  header: 'User',
  sortingFn: (rowA, rowB, columnId) => {
    const userA = rowA.getValue(columnId) as User;
    const userB = rowB.getValue(columnId) as User;
    return userA.lastName.localeCompare(userB.lastName);
  },
}

Programmatic Sorting

Using Table Instance

import { useActiveGrid } from '@workspace/active-grid';

function MyComponent() {
  const table = useActiveGrid();
  
  // Set single sort
  const sortByName = () => {
    table.setSorting([{ id: 'name', desc: false }]);
  };
  
  // Set multi sort
  const sortByMultiple = () => {
    table.setSorting([
      { id: 'status', desc: false },
      { id: 'createdAt', desc: true },
    ]);
  };
  
  // Clear sorting
  const clearSort = () => {
    table.setSorting([]);
  };
  
  // Toggle column sort
  const toggleNameSort = () => {
    const column = table.getColumn('name');
    column?.toggleSorting();
  };
}

Sort State

Reading Sort State

import { useActiveGrid } from '@workspace/active-grid';

function MyComponent() {
  const table = useActiveGrid();
  const sortingState = table.getState().sorting;
  
  // sortingState: [{ id: 'name', desc: false }]
  
  return (
    <div>
      {sortingState.length > 0 ? (
        <p>Sorted by: {sortingState.map(s => s.id).join(', ')}</p>
      ) : (
        <p>No sorting applied</p>
      )}
    </div>
  );
}

Initial Sort State

Set initial sorting when the table loads:

Server-Side Sorting

For server-side mode, sorting state is passed to your fetch function:

Sort Indicators

The grid automatically displays sort indicators in column headers:

↑ - Ascending sort
↓ - Descending sort
Badge with number - Multi-sort order

Custom Sort Header

Advanced Examples

Priority Sort

Null/Undefined Handling

Version Number Sort

Best Practices

✅ DO

Enable sorting on data columns
Disable sorting on action columns
Provide custom sort for complex types
Handle null/undefined values
Use case-insensitive sort for text

❌ DON'T

Don't sort large datasets client-side
Don't ignore null/undefined values
Don't forget to type sort functions
Don't mix sort types incorrectly
Don't enable sort on computed columns without custom function

Performance Tips

For large datasets (>1000 rows), consider:

Using server-side sorting
Memoizing custom sort functions
Using built-in sort types when possible
Enabling virtualization

Keyboard Shortcuts

Click header to sort
Shift + Click for multi-column sort
Click three times to clear sort
