Data Grid 2 Widget – Last Column Resizer Not Available Across All Data Grids

Introduction

We have observed this behavior in Mendix 9, specifically version 9.24.34, where the last column in Data Grid 2 cannot be resized. We have also noticed similar behavior in Mendix 10, although the issue appears to be inconsistent across implementations. This affects applications using the Data Widgets module from the Marketplace and has been reproduced across multiple Data Grid 2 instances. After raising a support ticket, we were informed that this is currently the expected behavior rather than a defect.

In Data Grid 2, the last column is intentionally used as a buffer to absorb remaining space and maintain the overall grid width. As a result, the last column cannot be resized by users, and no resize handler is rendered for that column.

Problem

This behavior can be limiting in scenarios where users need full control over column widths. During testing, we observed that:

• The last column in every Data Grid 2 instance cannot be resized.
• The resize handler is not rendered for the final column.
• The behavior occurs regardless of whether the Column Selector is enabled or disabled.
• The behavior persists even when column resizing is enabled through Personalization settings.
• All other columns can be resized normally.

Initially, this appeared to be a widget issue because the resize element was missing from the DOM. However, support confirmed that this is the expected behavior.

Suggested Enhancement

Provide a configurable option that allows developers to choose how the last column behaves:

• Default (current behavior): Last column acts as a buffer and absorbs remaining space.
• Optional behavior: Last column can be resized like any other column and retains its user-defined width.

This would provide greater flexibility for applications that require precise column sizing while maintaining backward compatibility with the current implementation.
