# useAutosize: Controlled values

> Typing fires `input`, but setting `value` from code doesn't. Pass the value as the third argument and the textarea refits when you insert a template or clear it.

Example: https://hextaui.com/docs/use-autosize/examples/controlled
Component docs: https://hextaui.com/docs/use-autosize.md

## Add this example

```bash
npx shadcn@latest add https://hextaui.com/r/use-autosize-controlled.json
```

This adds `components/examples/use-autosize/controlled.tsx` with the useAutosize component and the HextaUI theme tokens.

## Source

```tsx title="components/examples/use-autosize/controlled.tsx"
"use client"

import * as React from "react"

import { Button } from "@/components/ui/button"
import { useAutosize } from "@/hooks/use-autosize"

const template = `Hi team,

The release is out. Highlights:
- Faster search
- Offline drafts
- New keyboard shortcuts

Thanks!`

export function UseAutosizeControlled() {
  const ref = React.useRef<HTMLTextAreaElement>(null)
  const [value, setValue] = React.useState("")
  useAutosize(ref, true, value)

  return (
    <div className="flex w-full max-w-sm flex-col gap-3">
      <textarea
