Activities Grid
Available in: All plans
Last updated: 26-Feb-2026
Overview
The Activities Grid is the primary workspace in Kazinex. It displays every activity in the loaded schedule as a fully interactive, spreadsheet-style data grid. You can sort, filter, group, resize, reorder columns, and — in Editor Mode — edit cell values inline.
The grid is powered by TanStack Table v8 with virtual scrolling, so it handles projects with 10,000+ activities without slowdown. Only rows visible in the viewport are rendered to the DOM.
View Modes
The top-right corner of the toolbar contains a three-button toggle:
| Mode | Description |
|---|---|
| Grid | Full-width data grid with no Gantt chart. Best for data-heavy analysis. |
| Split | Grid and Gantt chart side by side with a draggable divider (default 50/50). |
| Gantt | Full-width Gantt chart with no grid columns. Best for visual scheduling. |
In Split mode:
- Drag the centre divider to resize panes (minimum 260 px each side).
- Both panes share a synchronized vertical scroll.
- Each pane has its own horizontal scrollbar.

Column Features
Sorting
Click any column header to sort:
- First click → Ascending (↑)
- Second click → Descending (↓)
- Third click → Unsorted
Sorting is single-column — clicking a different header replaces the previous sort.
Resizing
Drag the right edge of any column header to resize it. A tooltip shows the current width in pixels. Minimum width is 50 px; maximum is 2,000 px.
Sticky Columns
Activity ID and Activity Name are pinned (sticky) to the left edge by default. They stay visible as you scroll horizontally through other columns.
Column Chooser
Click the Columns toolbar button to launch the Column Chooser. See Column Chooser for full details.
Row Features
Selection
| Interaction | Effect |
|---|---|
| Click a row | Select that single activity |
| Ctrl+Click (or Cmd+Click) | Add or remove the row from your selection |
| Shift+Click | Select a range of rows |
Selected rows are highlighted with a blue left-border accent.
Critical Path Highlighting
Activities on the critical path are displayed with a red-tinted background and red text. This makes it easy to spot schedule-driving activities at a glance.
Toggle critical path highlighting on or off in the Format dialog.
Jump-to-Activity Glow
When you navigate to a specific activity (for example, from the Quality Check Detail Drawer or "Find in Grid"), the target row plays a brief glow animation so you can locate it immediately.
Expandable Groups
When grouping is active, group header rows appear with a chevron (▸/▾) toggle. Click the chevron to expand or collapse a group. Each group header shows the group label, activity count, and aggregated values (sums, averages) in the appropriate columns.
Tip: Hold Shift and click a group chevron to expand or collapse that group and all its descendants recursively.
Cell Editing
Cell editing is available only in Editor Mode (Pro and Enterprise plans).

Performance
The grid uses virtual scrolling — only the rows visible in your viewport (plus a small buffer) are rendered. This means:
- 10,000+ activities render instantly.
- Scrolling is smooth regardless of project size.
- Memory usage stays low even with very large schedules.
Aggregation calculations (sums, averages for group headers) are cached and recalculated only when data changes, not on every scroll or render.
