form default value
with a code like the following, how can I set a value programmatically ?
<FormControl fullWidth>
<FormLabel
requires
>
{t(
"order-items.fields.customer",
)}
</FormLabel>
<Controller
control={control}
name="customer"
rules={{
required: t("errors.required") + ': ' + t("order-items.fields.customer"),
}}
defaultValue={null as any}
render={({ field }) => (
<Autocomplete
size="small"
{...customersdata}
{...field}
onChange={(, value) => {
field.onChange(value);
}}
getOptionLabel={(item) => {
return item.customer_legal_name
? item.customer_legal_name
: "";
}}
isOptionEqualToValue={(
option,
value,
) =>
value === undefined ||
option?.id?.toString() ===
(
value?.id ??
value
)?.toString()
}
renderInput={(params) => (
<TextField
{...params}
variant="outlined"
error={
!!errors.customer
?.message
}
required
/>
)}
/>
)}
/>
</FormControl>

Hi @dannywhiteagile. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
To programmatically set a value in a form field managed by
react-hook-form
, you can use the setValue
function provided by the useForm
hook. However, the provided code does not include the setValue
function, so I can't provide a specific example based on the given code.
Here's a general example of how you can use the setValue
function:
In this example, setValue
is used to set the value of the customer
field to yourValue
. You would replace yourValue
with the actual value you want to set.
Please note that you need to call setValue
after the form has been rendered and the fields have been registered. If you call setValue
too early (for example, before the form fields have been registered), it won't have any effect.
For more information, you can refer to the React Hook Form documentation (https://react-hook-form.com/api/useform/setvalue).
Please note that the provided extracts do not contain specific information about setting values programmatically in the context of Refine and Ant Design. The information provided here is based on the general usage of react-hook-form
.

@kapa.ai how to trigger a change event on the associated element?
Let me check the knowledge base for you. One moment! :books:
----------------------
To trigger a change event on an associated element in a form managed by
react-hook-form
, you can call the onChange
function provided by the field
object. This function is used to notify the form that the field's value has changed.
Here's an example based on the code you provided:
In this example, the onChange
function is called whenever the value of the Autocomplete
component changes. The new value is passed to field.onChange
, which updates the form state and triggers any side effects (like validation) that depend on the field's value.
Please note that the onChange
function expects the new value as its argument. If your onChange
handler receives an event object (like in a native HTML input), you should pass event.target.value
to field.onChange
.
For more information, you can refer to the React Hook Form documentation (https://react-hook-form.com/api/usecontroller/controller).

@kapa.ai i need to trigger a change event programmatically
Let me check the knowledge base for you. One moment! :books:
----------------------
To programmatically trigger a change event, you can call the
onChange
function provided by the field
object from the Controller
component in react-hook-form
. However, you need to ensure that the onChange
function is called with the correct argument, which is the new value of the field.
Here's a general example:
In this example, field.onChange
is called with newValue
as its argument. This will update the form state and trigger any side effects (like validation) that depend on the field's value.
Please note that the onChange
function expects the new value as its argument. If your onChange
handler receives an event object (like in a native HTML input), you should pass event.target.value
to field.onChange
.
For more information, you can refer to the React Hook Form documentation (https://react-hook-form.com/api/usecontroller/controller).

@kapa.ai i need something like form.customer.change()
Let me check the knowledge base for you. One moment! :books:
----------------------
To programmatically trigger a change event in a form field, you can use the
setValue
function provided by the useForm
hook in react-hook-form
. This function not only allows you to set the value of a field, but it also triggers a re-render and runs the validation rules for the field.
Here's a general example:
In this example, setValue
is used to set the value of the customer
field to newValue
and trigger a re-render and validation. You would replace newValue
with the actual value you want to set.
Please note that you need to call setValue
after the form has been rendered and the fields have been registered. If you call setValue
too early (for example, before the form fields have been registered), it won't have any effect.
For more information, you can refer to the React Hook Form documentation (https://react-hook-form.com/api/useform/setvalue).
