Encountering difficulties with displaying error messages on the Material UI datepicker

I am currently utilizing React Material UI

There is a need to display an error based on certain conditions that will be calculated on the backend.

Although I have implemented Material UI date picker, I am facing issues with displaying errors.

import * as React from 'react';
import TextField from '@mui/material/TextField';
import AdapterDateFns from '@mui/lab/AdapterDateFns';
import LocalizationProvider from '@mui/lab/LocalizationProvider';
import DatePicker from '@mui/lab/DatePicker';

const PickupDatePickerComponent = (props) => {

  const [value, setValue] = React.useState(null);

  const handleChange = (newValue)=>{
    setValue(newValue);
  }

  const todayDate = new Date();

  return (
    <LocalizationProvider style={{ width:"100%"}} dateAdapter={AdapterDateFns}>
      <DatePicker
        label="example"
        value={value}
        onChange={handleChange}
        minDate={todayDate}
        renderInput={(params) => <TextField 
          error
          helperText="Your error message" 
          {...params} sx={{ width: "100%" }} 
        />}
        onError={true}
        error
        helperText="Your error message"
      />
    </LocalizationProvider>
  );
}

export default PickupDatePickerComponent

The error property seems to be ineffective in both, <Input/> and <DatePicker/>, leading to no red border for the errors as expected.

Answer №1

After inserting the error attribute inside {...params} sx={{ width:"100%" }}
make sure it appears like this

renderInput={(params) => <TextField 
      
      {...params} sx={{ width:"100%" }} 
error
helperText="Error message goes here" 
    />}

Answer №2

For those utilizing DatePicker V6, the following solutions are currently ineffective. In the latest version, renderInput has been replaced by slotProps. Take a look at the revised code snippet below.

Code:

<Controller
  name={name}
  control={control}
  render={({ field, fieldState: { error } }) => (
    <LocalizationProvider dateAdapter={AdapterDayjs}>
      <DatePicker
        {...field}
        label={label}
        slotProps={{
          textField: {
            fullWidth: fullWidth,
            variant: 'outlined',
            error: !!error,
            helperText: error?.message,
          },
        }}
        {...other}
      />
    </LocalizationProvider>
  )}
/>;

I followed the recommendation in the documentation and passed a callback function to the onError prop. You can check out this working demo that is based on your code.

Answer №4

Since I couldn't figure out the meaning of Controller as mentioned by @Necip Sunmaz, I decided to create a new state instead.

const [dateError, setDateError] = useState(undefined);

<DateTimePicker
  slotProps={{
    textField: {
      error: !!dateError,
      helperText: dateError,
    },
  }}
  onError={(err) => setDateError(err)}
  minDateTime={filter.date.startDate} // using another date state to trigger the error
/>

Answer №5

The most recent update to the MUI (V6) DatePicker has introduced a change where the renderInput function is now replaced by slotProps. If you were using the previous solution with renderInput, it would now appear like this:

<DatePicker ...
           slotProps={{
             textField: {
               helperText: isError?"Some error message":""
               error: isError,
             },
           }}
...  />
