Hi @koop_g. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The control parameter returned by useForm in refine is an important object used for managing form state and integrating with controlled form components. Here's what you need to know about it: 1. Type: The control object is of type Control from React Hook Form. It's part of the return value from the useForm hook. 2. Purpose: The main purpose of the control object is to register and manage controlled components in your form, especially when working with external UI libraries like Material UI or Ant Design. 3. Usage: The control object is typically passed to the Controller component from React Hook Form. This allows you to integrate controlled input components with React Hook Form's state management and validation system. Here's an example of how it's used:

<Controller
  control={control}
  name="firstName"
  render={({ field }) => (
    <TextField
      {...field}
      label="First Name"
      error={!!errors.firstName}
      helperText={errors.firstName && `${errors.firstName.message}`}
    />
  )}
/>

<Controller
  control={control}
  name="firstName"
  render={({ field }) => (
    <TextField
      {...field}
      label="First Name"
      error={!!errors.firstName}
      helperText={errors.firstName && `${errors.firstName.message}`}
    />
  )}
/>

In this example, the control object is passed to the Controller component, which then manages the state and validation for the TextField component. 4. Benefits: Using the control object with Controller allows you to: - Integrate controlled components seamlessly with React Hook Form - Manage form state for complex input components - Apply validation rules to controlled inputs - Access form values and errors for controlled inputs For more detailed information on using control and Controller with refine's useForm, you can refer to the React Hook Form Validation Examples in the refine documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai in my page I don't really use useForm, can I set a control object manually with out useform ?

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the knowledge sources provided, there isn't specific information about manually setting a control object without using useForm in refine. The control object is typically obtained from the useForm hook and is designed to work in conjunction with React Hook Form's state management and validation system. If you're not using useForm in your page, it suggests that you might not be leveraging refine's form management capabilities. The control object is specifically tied to React Hook Form's functionality, which refine integrates through its @refinedev/react-hook-form adapter. Without using useForm, you wouldn't have access to the control object as it's provided. If you're looking to manage form state without useForm, you might need to consider alternative approaches to form management that don't rely on React Hook Form or refine's form utilities. However, it's worth noting that refine's form management through useForm is designed to simplify many aspects of form handling, including data fetching, submission, and integration with refine's data provider. If you're working within a refine project, it's generally recommended to use the provided form hooks for consistency and to take advantage of refine's built-in features. If you have a specific use case or reason for not using useForm, you might want to reconsider your approach or provide more context about your requirements. This could help in suggesting a more appropriate solution within the refine ecosystem. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
