Understanding the AG Grid Pagination Refresh Issue on Sort

If you're working with AG Grid in an Angular application and facing issues with pagination refreshing upon sorting, you're not alone. Many developers experience this challenge, especially when using server-side data fetching. Let's explore this problem and how to resolve it effectively.

The Problem Explained

In AG Grid, the typical expectation when clicking on a column header to sort is that the data should sort without any interruptions; however, some users encounter a scenario where the grid refreshes and does not adequately reflect the sort operation. This situation arises due to how the onGridReady event interacts with pagination and sorting.

For example, when the grid initializes (onGridReady), it may inadvertently trigger an API call to refresh the grid's row options, thus overriding the sort action. If your grid is set up for server-side pagination and sorting, the conflict between the two can lead to this frustrating experience.

Here's how a developer described the issue:

Solutions to Prevent Refreshing on Sort

1. Reviewing Server-Side Configurations

The first step in resolving the issue is to understand the parameters set for your AG Grid component. Pay close attention to the options that manage server-side rendering. In particular:

Server-Side Sorting: If only some of your pages require server-side sorting while others do not, ensure that you are not binding unnecessary server-side configurations to all pages.

2. Removing Unnecessary Callbacks

In many cases, developers overlook the server-side rendering aspects. For example, the callback function that fetches data on the onGridReady event might be designed solely for handling server-side sorting when it’s not needed:

Solution: If the server-side sorting is not essential for certain pages, remove this callback and any server-side options from the grid initialization. This allows your application to handle sorting on the client side for those pages, thus preventing unwanted refreshes.

3. Reassessing Data Fetching Logic

Make sure that any data-fetching logic is only triggered when necessary (e.g., on pagination changes). This approach might look something like this:

By doing this, the API call will execute solely during pagination changes, avoiding unnecessary calls during sorting events.

Final Thoughts

Resolving the pagination refresh issue in AG Grid when sorting is primarily about carefully managing server-side configurations and callbacks. By:

Removing unnecessary server-side functionalities

Avoiding callbacks during sorting events

Ensuring data fetching only on pagination changes

You can maintain a smooth user experience without interruptions.

If you face similar issues in the future, always review your AG Grid settings to ensure they align correctly with your intended functionality.
