To dim the save button if the form does not change when using

useForm

useForm

in refine, you can utilize the

saveButtonProps

saveButtonProps

returned by the

useForm

useForm

hook. This prop automatically handles the disabled state of the save button based on whether the form has changed or not. Here's how you can implement it:

For Ant Design UI:

import { Edit, useForm } from "@refinedev/antd";
import { Form, Input } from "antd";

const PostEdit: React.FC = () => {
  const { formProps, saveButtonProps } = useForm<IPost>();

  return (
    <Edit saveButtonProps={saveButtonProps}>
      <Form {...formProps} layout="vertical">
        <Form.Item
          label="Title"
          name="title"
          rules={[
            {
              required: true,
            },
          ]}
        >
          <Input />
        </Form.Item>
      </Form>
    </Edit>
  );
};

import { Edit, useForm } from "@refinedev/antd";
import { Form, Input } from "antd";

const PostEdit: React.FC = () => {
  const { formProps, saveButtonProps } = useForm<IPost>();

  return (
    <Edit saveButtonProps={saveButtonProps}>
      <Form {...formProps} layout="vertical">
        <Form.Item
          label="Title"
          name="title"
          rules={[
            {
              required: true,
            },
          ]}
        >
          <Input />
        </Form.Item>
      </Form>
    </Edit>
  );
};

import { Edit, useForm } from "@refinedev/antd";
import { Form, Input } from "antd";

const PostEdit: React.FC = () => {
  const { formProps, saveButtonProps } = useForm<IPost>();

  return (
    <Edit saveButtonProps={saveButtonProps}>
      <Form {...formProps} layout="vertical">
        <Form.Item
          label="Title"
          name="title"
          rules={[
            {
              required: true,
            },
          ]}
        >
          <Input />
        </Form.Item>
      </Form>
    </Edit>
  );
};

import { Edit, useForm } from "@refinedev/antd";
import { Form, Input } from "antd";

const PostEdit: React.FC = () => {
  const { formProps, saveButtonProps } = useForm<IPost>();

  return (
    <Edit saveButtonProps={saveButtonProps}>
      <Form {...formProps} layout="vertical">
        <Form.Item
          label="Title"
          name="title"
          rules={[
            {
              required: true,
            },
          ]}
        >
          <Input />
        </Form.Item>
      </Form>
    </Edit>
  );
};

In this example, the

saveButtonProps

saveButtonProps

is passed to the

<Edit>

<Edit>

<Edit>

<Edit> component, which will automatically handle the disabled state of the save button Ant Design UI - Save Button (https://refine.dev/docs/ui-integrations/ant-design/components/buttons/save-button/).

For React Hook Form:

If you're using React Hook Form with refine, you can use the

formState.isDirty

formState.isDirty

formState.isDirty

formState.isDirty property to determine if the form has changed:

const { register, formState: { isDirty } } = useForm();

// In your JSX:
<button
  disabled={!isDirty}
  type="submit"
>
  Save
</button>

const { register, formState: { isDirty } } = useForm();

// In your JSX:
<button
  disabled={!isDirty}
  type="submit"
>
  Save
</button>

const { register, formState: { isDirty } } = useForm();

// In your JSX:
<button
  disabled={!isDirty}
  type="submit"
>
  Save
</button>

const { register, formState: { isDirty } } = useForm();

// In your JSX:
<button
  disabled={!isDirty}
  type="submit"
>
  Save
</button>

This approach disables the submit button when the form is not dirty (i.e., hasn't changed) React Hook Form - Form Validation (https://refine.dev/blog/react-hook-form/#form-validation-in-react-hook-form-the-isvalid-prop).

By using these methods, the save button will be dimmed (disabled) when the form has not been changed, providing visual feedback to the user about the form's state.

How about for case form data changed and undo? @kapa.ai

Let me check the knowledge base for you again. One moment!

----------------------
If you want to handle the case where form data is changed and then undone, you can use the

formState.isDirty

formState.isDirty

formState.isDirty

formState.isDirty property from the

useForm

useForm

hook in React Hook Form. This property will be

true

true

if the form data has been changed from its initial values, and

false

false

if the form data matches the initial values (even if changes were made and then undone).

Here's an example:

const { register, formState: { isDirty } } = useForm();

// In your JSX:
<button
  disabled={!isDirty}
  type="submit"
>
  Save
</button>

const { register, formState: { isDirty } } = useForm();

// In your JSX:
<button
  disabled={!isDirty}
  type="submit"
>
  Save
</button>

const { register, formState: { isDirty } } = useForm();

// In your JSX:
<button
  disabled={!isDirty}
  type="submit"
>
  Save
</button>

const { register, formState: { isDirty } } = useForm();

// In your JSX:
<button
  disabled={!isDirty}
  type="submit"
>
  Save
</button>

In this example, the

isDirty

isDirty

isDirty

isDirty property is used to disable the save button when the form data matches the initial values. This means that if a user makes changes to the form and then undoes those changes, the save button will be disabled.

Please note that this behavior depends on the form library you're using with Refine. The example above is for React Hook Form. If you're using a different form library, you'll need to refer to its documentation to see how to handle this case.
