Search or Filter Paginated Data Using StartDate and EndDate in Angular

If you're working with paginated data in Angular and using an ASP.NET Core backend, you might often find the need to filter this data based on specific date ranges. In this guide, we’ll explore how to achieve this by allowing users to select a start date and an end date using a datepicker, and then displaying the filtered results in a paginated table format.

Background Context

In our scenario, we're consuming an API endpoint that returns data for merchants. The goal is to provide users the capability to filter this data based on their chosen start and end dates. As an example, the API call looks like this:

API Response Structure

The API returns a JSON response that includes the following important fields:

currentPage: Current page number

pageSize: Number of items per page

totalRecord: Total number of records available

Implementation Steps

1. Modifying the Service

To begin with, you need to modify your Angular service to accept startDate and endDate parameters when calling the API. Here's how you can extend your existing method:

2. Updating the Component

Next, modify the component to use the newly added parameters. Update the loadAllMerchants method to include startDate and endDate:

3. Modifying the HTML Template

Now that the component methods are ready to handle date filters, you'll need to reflect this in the HTML by adding date pickers for selecting the dates:

4. Triggering the Load Function

Lastly, you need to trigger the loadAllMerchants function when the user selects the dates and clicks a submit button (not shown in the code snippets above). Generally, this could be a simple button wired to call your load method.
