How to Change ag-Grid Date Filter Placeholder Format

If you’re using ag-Grid in your React application for table display, you may come across a scenario where you need to change the date format of the datepicker filter’s placeholder. By default, ag-Grid uses the format “mm/dd/yyyy” for the datepicker filter, but you want to change it to “dd/mm/yyyy”. In this blog post, we will explore how to achieve this customization in ag-Grid.

Import the required dependencies

To get started, make sure you have the necessary dependencies installed in your project. You will need ag-Grid, React, and Moment.js. Import the required components and libraries:

code




import React from 'react';
import { AgGridColumn, AgGridReact } from 'ag-grid-react';
import moment from 'moment';
import 'ag-grid-community/dist/styles/ag-grid.css';
import 'ag-grid-community/dist/styles/ag-theme-alpine.css';

Define the column definition

In your column definition, specify the filterParams property for the date column to customize the datepicker filter’s behavior:

code
<AgGridColumn field="dateField" headerName="Date Field" filter="agDateColumnFilter" filterParams={{ browserDatePicker: true, placeholder: 'dd/mm/yyyy' }} />

Here, we set browserDatePicker to true to enable the browser’s native datepicker. Additionally, we set the placeholder property to ‘dd/mm/yyyy’ to change the format of the datepicker filter’s placeholder.

Customize the date format

To ensure that the date values in the column are displayed and filtered in the desired format, you can use the valueFormatter and comparator properties in the column definition:

code






<AgGridColumn field="dateField" headerName="Date Field" filter="agDateColumnFilter"
    filterParams={{ browserDatePicker: true, placeholder: 'dd/mm/yyyy' }}
    valueFormatter={params => moment(params.value).format('DD/MM/YYYY')}
    comparator={function (filterLocalDateAtMidnight, cellValue) {
        // Custom comparison logic here
    }}
/>

The valueFormatter function formats the date value in the desired format, while the comparator function handles the custom comparison logic for date filtering.

Render the ag-Grid component

Finally, render the ag-Grid component in your application, passing the column definition and data:

code












const App = () => {
    const rowData = [...] 










; // Your data goes here

    return (
        <div className="ag-theme-alpine" style={{ height: '500px', width: '100%' }}>
            <AgGridReact rowData={rowData}>
                {/* Add your column definitions here */}
            </AgGridReact>
        </div>
    );
};

export default App;

Tips for Customizing ag-Grid Date Filtering

In addition to the steps outlined above, here are a few additional tips to further customize the date filtering functionality in ag-Grid:

1. Localization: If you want to customize the date format and localization for all datepickers in your application, you can use the localeText property in the ag-Grid configuration. For example, to change the date format to “DD/MM/YYYY” and customize other localization strings, you can do the following:

code






const gridOptions = {
  // Other grid options...
  localeText: {
    dateFormatOoo: 'DD/MM/YYYY', // Customize the date format
    // Other localization strings...
  },
};

2. Custom Filter Component: If you require more advanced customization for the date filtering functionality, you can create a custom filter component in React and use it in your column definition. This gives you full control over the appearance and behavior of the date filter. You can refer to the ag-Grid documentation for more details on creating custom filter components.

3. Date Picker Options: ag-Grid provides various options to customize the date picker, such as disabling certain dates, restricting the selectable range, or using a different date picker library. Explore the ag-Grid documentation to learn more about the available options and how to use them.

4. Handling Time Zones: When working with date values, it’s important to consider time zones. Ensure that the date values in your data and the datepicker filter are consistently handled in the desired time zone. You may need to adjust the date values or utilize libraries like Moment.js to handle time zone conversions.

5. Testing and Validation: After implementing custom date filtering, thoroughly test the functionality to ensure that it behaves as expected in different scenarios. Check for edge cases and validate the filtered results against your data set to confirm accuracy.

Conclusion

Customizing the date format and functionality of the ag-Grid datepicker filter can greatly enhance the user experience and make it more intuitive for your application’s users. By following the steps outlined in this blog post and considering the additional tips provided, you can achieve the desired customization and ensure a seamless date filtering experience in your ag-Grid-based application.
