What is the process for configuring the Material UI DataGrid's initial state filter model specifically for dates?

edit

To configure the Material UI DataGrid's initial state filter model specifically for dates, follow these steps:

1. Define the initial state of the filter model for dates.

const initialDateFilters = {
  dateFrom: null,
  dateTo: null,
}

1. Create a custom filter operator for the date filter type.

import { GridFilterOperatorValue } from '@material-ui/data-grid';

type DateOperator = 'isAfter' | 'isBefore' | 'isOnOrAfter' | 'isOnOrBefore' | 'isBetween';

const dateOperators: { [key in DateOperator]: GridFilterOperatorValue } = {
  isAfter: {
    label: 'Is after',
    value: '>',
    getApplyFilterFn: (filterItem) => (params) => {
      const cellDate = new Date(params.value);
      const filterDate = new Date(filterItem.value);
      return cellDate > filterDate;
    },
  },
  // add more operators as needed
};

1. Define the date filter model for the DataGrid.

import { GridFilterModel } from '@material-ui/data-grid';

interface DateFilterModel extends GridFilterModel {
  dateFrom: {
    value: Date | null;
    operatorValue: string;
  };
  dateTo: {
    value: Date | null;
    operatorValue: string;
  };
}

const initialFilterModel: DateFilterModel = {
  items: [],
  dateFrom: {
    value: null,
    operatorValue: 'isOnOrAfter',
  },
  dateTo: {
    value: null,
    operatorValue: 'isOnOrBefore',
  },
};

1. Define the column with the custom filter operator.

import { GridColDef } from '@material-ui/data-grid';

const columns: GridColDef[] = [
  {
    field: 'date',
    headerName: 'Date',
    filterOperators: dateOperators,
    filterable: true,
    filterType: 'date',
    valueGetter: (params) => new Date(params.value).toLocaleDateString(),
  },
  // add more columns as needed
];

1. Pass the initial state filter model, custom filter operator, and column definition to the DataGrid.

import { DataGrid, GridFilterModel } from '@material-ui/data-grid';

function MyGrid() {
  const [dateFilters, setDateFilters] = React.useState(initialDateFilters);
  const handleFilterChange = (model: GridFilterModel) => {
    setDateFilters(model as DateFilterModel);
  };
  return (
    <DataGrid
      columns={columns}
      rows={rows}
      filterMode="server"
      onFilterModelChange={handleFilterChange}
      filterModel={initialFilterModel}
    />
  );
}
