Documentation references row hover but none found

[JoshuaHintze]

Describe the issue
On the docs page it mentions here: https://rv-grid.com/guide/patterns#Event-Handling-and-Customization the following:

Pattern: Hook into various events (e.g., cell click, row hover) for custom behaviors.

However looking through the events and hooks page I didn't see any mention of hover

I would like to be able to hover over a row and have an icon show up in the first cell for deletion of the entire row.

Thanks for pointing this out. There is no dedicated rowhover / hover event in RevoGrid at the moment. The docs wording there is meant as a general customization pattern, not as a named RevoGrid event.

For this specific case, the recommended approach is to render the delete action in the first/action column and show it with CSS on the rendered row hover:

const grid = document.querySelector('revo-grid');

let source = [
  { id: 1, name: 'Steve' },
  { id: 2, name: 'John' },
];

function deleteRow(id: number) {
  source = source.filter(row => row.id !== id);
  grid.source = source;
}

grid.source = source;
grid.columns = [
  {
    prop: 'actions',
    name: '',
    size: 48,
    readonly: true,
    cellTemplate: (h, { model }) =>
      h(
        'button',
        {
          class: 'row-delete-action',
          title: 'Delete row',
          onMouseDown: (e: MouseEvent) => e.stopPropagation(),
          onClick: (e: MouseEvent) => {
            e.stopPropagation();
            deleteRow(model.id);
          },
        },
        '×',
      ),
  },
  { prop: 'name', name: 'Name' },
];

revo-grid .row-delete-action {
  opacity: 0;
  pointer-events: none;
}

revo-grid .rgRow:hover .row-delete-action,
revo-grid .row-delete-action:focus-visible {
  opacity: 1;
  pointer-events: auto;
}

A couple of notes:

• Use a stable row id for deletion instead of relying on the visible row index, especially when sorting/filtering is enabled.
• beforerowrender and beforecellrender are render hooks and can be used for customization, but they are not hover events.

Closing this as answered. We can adjust the docs wording separately so it does not imply a dedicated row-hover event exists.
