Angular Data Grid Row Reordering

Some lists have an order that only a person can decide: a task backlog, a playlist, the steps of a workflow. rowOrder gives each row a grip, and the grid tells you where the row was dropped — you own the data, so you own the new order.

Row reordering

[rowOrder]="true" adds a narrow handle column before the data columns. Only the grip starts a drag: a row is full of interactive content — checkboxes, editors, custom cells — that a whole-row handle would swallow.

import { Component, signal } from '@angular/core'
import { DataGridComponent } from '@coreui/angular-data-grid'
import type { DataGridColumn, DataGridItem, DataGridRowOrderChangeEvent } from '@coreui/angular-data-grid'

@Component({
  selector: 'docs-data-grid-row-order-example',
  imports: [DataGridComponent],
  template: `
    <c-data-grid
      [columns]="columns"
      [items]="items()"
      [itemKey]="itemKey"
      [rowOrder]="true"
      [sorting]="false"
      [virtualization]="false"
      (rowOrderChange)="onRowOrderChange($event)"
    />
  `
})
export class DataGridRowOrderExample {
  readonly columns: DataGridColumn[] = [
    { key: 'task', label: 'Task' },
    { key: 'owner', label: 'Owner' },
    { key: 'status', label: 'Status' }
  ]
readonly items = signal<DataGridItem[]>([
    {
 id: 1, task: 'Draft the release notes', owner: 'Alice', status: 'In progress'
},
    {
 id: 2, task: 'Review the API surface', owner: 'Bob', status: 'Blocked'
},
    {
 id: 3, task: 'Ship the beta', owner: 'Carol', status: 'Todo'
},
    {
 id: 4, task: 'Update the changelog', owner: 'Dave', status: 'Todo'
}
  ])
readonly itemKey = (item: DataGridItem) => String(item.id)

  onRowOrderChange(event: DataGridRowOrderChangeEvent) {
    this.items.set(event.items)
  }
}

The contract

The grid never mutates items. Dropping a row fires (rowOrderChange) with everything needed to apply the move — the same contract inline editing uses:

Until you apply it, nothing changes on screen. That is deliberate: the order is usually persisted, and a row that snaps back when the request fails is better than one that lies.

The indexes are positions in items, not in the rendered window — in pagination mode the page offset is already added, so dragging the first row of page 2 reports oldIndex: 10, not 0.

The drag interaction

Row dragging is the same pointer-based controller as column dragging, turned on its side: a ghost with the row’s first cell, a live preview where the rows it passes slide aside and it slides into the gap, edge auto-scroll for long lists, and Escape to cancel. It works the same with a mouse, a pen and a finger, and honours prefers-reduced-motion.

Options

The handle’s accessible name comes from labels.reorderRow — see localization.
