Bug Fix: Resolving Column Order Issues with Pinned Columns and Selection Column Definitions

In the realm of data visualization and grid-based applications, maintaining the correct order of columns is crucial for user experience and functionality. However, when dealing with pinned columns and selection column definitions, issues can arise, leading to incorrect column ordering. This article delves into a specific bug where resetting columns with both a pinned column and a pinned selection column definition results in the wrong order.

The Bug: Wrong Order When Resetting Columns

Steps to Reproduce the Bug

To reproduce the bug, follow these steps:

  1. Set a column with pinned: "left" and lockPosition: "left": This sets a column to be pinned on the left side of the grid, ensuring it remains in the same position even when scrolling.
  2. Add a selectionColumnDef pinned to the left: This adds a selection column definition that is also pinned to the left side of the grid.
  3. Reset columns: This is where the bug occurs, as the column order changes unexpectedly.

Actual Behaviour

When resetting columns with both a pinned column and a pinned selection column definition, the actual behaviour is that the selection column definition is no longer the first column, and the column order changes.

Expected Behaviour

The expected behaviour is that the checkbox should remain the first column, maintaining its pinned position.

Version

The issue occurs in version 3.1.0.

Does the Issue Occur for a Specific Framework Only?

The issue is specific to the React framework.

Is the Issue Only Observable on a Specific Browser?

The issue is observable on all browsers.

The issue arises from the way the grid handles pinned columns and selection column definitions. When resetting columns, the grid attempts to reorder the columns based on their pinned positions. However, in this specific scenario, the selection column definition is not being treated as a pinned column, resulting in the incorrect order.

To better understand the issue, let's take a look at the code. The reproducible scenario can be found in the following link:

In this code, we can see that the selection column definition is being added as a pinned column to the left side of the grid. However, when resetting columns, the grid is not maintaining the correct order.

To resolve this issue, we can try the following solutions:

  1. Modify the selection column definition to be treated as a pinned column: This can be achieved by modifying the code to treat the selection column definition as a pinned column.
  2. Update the grid to correctly handle pinned columns and selection column definitions: This can be achieved by updating the grid's logic to correctly handle pinned columns and selection column definitions.

In conclusion, the bug where resetting columns with both a pinned column and a pinned selection column definition results in the wrong order is a specific issue that occurs in version 3.1.0 of the grid. By understanding the issue and analyzing the code, we can identify possible solutions to resolve this issue. By modifying the selection column definition to be treated as a pinned column or updating the grid to correctly handle pinned columns and selection column definitions, we can ensure that the column order is maintained correctly.

To prevent similar issues in the future, it's essential to:

  1. Thoroughly test the grid's functionality: This includes testing the grid's behaviour with different column configurations and scenarios.
  2. Update the grid's logic to handle edge cases: This includes updating the grid's logic to handle scenarios where pinned columns and selection column definitions are used together.

By following these best practices, we can ensure that the grid remains stable and functional, providing a seamless user experience.
