Meet TreeListView, now its own dedicated product

Our flagship tree grid is now a standalone Web Component with its own home, playground and demos at treelistview.com, with grouping, inline editing and a hundred-thousand-row ceiling.

• Framework-neutral: works in HTML5, Angular, React, Vue, Svelte & Blazor
• Unified tree + list views, with filtering, sorting & lazy-loading
• Grouping with live aggregates, a totals row and inline editing
• Per-column filters, multi-column sort and column reordering
• Banded two-row headers, and auto-fit column widths
• Cascading tri-state checkboxes, and parent roll-up summaries
• Multi-cell paste from a spreadsheet, with undo and redo
• Master/detail panels, and saved views your users name themselves
• Conditional formatting with data bars, and cell-level range selection
• A server-side data source, a built-in pager, and column virtualisation
• Real .xlsx export: sums and filters, not a table of text
• Typed React, Angular and Vue wrappers, generated from the component's own API
• Nineteen built-in themes, plus full CSS-variable theming
• Virtual scrolling: a hundred thousand rows stays responsive
• Live interactive playground: try it with your own data before you buy

Plan projects with Gantt, PERT and task boards

Three views of one plan, scheduled by the same critical-path engine on WinForms, WPF and the Web — so a plan gives the same dates on the desktop and in the browser.

• Gantt chart — a task list beside a timeline, with links, lag and lead, summaries, milestones, baselines and float
• PERT chart — the same plan as a network, with early and late dates and float in every box
• Task board — Kanban columns by status, with WIP limits and swimlanes
• Critical-path scheduling over a working calendar, with weekends and holidays
• Drag, resize and link by mouse, or do all of it from the keyboard
• Virtualised for plans of a thousand tasks and more; export to SVG or PNG, and print

Also for the desktop: WinForms · WPF

Reports in the browser, no report server

A report viewer and a report designer that run entirely in the browser: real pages drawn the same on screen, on paper and in the PDF — and your users can design their own reports.

• Report viewer — groups, totals, parameters, charts, crosstabs and barcodes, with find, zoom and contents
• Report designer — drag fields onto bands, add charts and crosstabs, and preview as you go
• Tagged, accessible PDF with your own fonts, for any alphabet; Excel and CSV export
• Drill down, drill through and sort, right in the page
• The same engine renders on a server, as a Node module
• Report definitions are plain JSON, safe to store and open

A million log lines, searched in the browser

The log stream opens server logs, access logs, audit trails and build output in the page and makes them searchable at once — with nothing uploaded, and no log server to run.

• Log stream — JSON lines, logfmt, syslog, access logs, CSV and plain text, read on sight
• Search by word, pattern and field: status:>=500, level:>=warn, exclusions and OR
• A timeline of the errors, and each field's commonest values, a click from a filter
• Emails, IP addresses, card numbers, tokens and keys masked on screen and in every export
• Live from a WebSocket or server-sent events, reconnected when it drops
• Bookmarks, and the whole view as one short string for a link or a ticket
