{{DefaultAPISidebar("DOM")}}

The **`ariaRowCount`** property of the {{domxref("ElementInternals")}} interface reflects the value of the `aria-rowcount` attribute, which defines the total number of rows in a table, grid, or treegrid.

> **Note:** Setting aria attributes on `ElementInternals` allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the [Accessibility Object Model explainer](https://wicg.github.io/aom/explainer.html#default-semantics-for-custom-elements-via-the-elementinternals-object).

## Syntax

```js
let ariaRowCount = ElementInternals.ariaRowCount;
ElementInternals.ariaRowCount = ariaRowCount;
```

### Value

A {{domxref("DOMString")}} which contains an integer.

## Examples

In this example the value of `ariaRowCount` is set to "100".

```js
this.internals_.ariaRowCount = "100";
```
