TreeGrid 6.6 released

Gantt
Added Critical path management (CPM). The chart calculates Slack column values, how much the task can be moved forward (delayed), before it affects project end date.
The incomplete critical tasks are colored in orange. Error tasks (those cannot be finished before project end date) are colored in red. Other incomplete tasks are in blue, complete tasks in green. All these colors can be changed in css file.
The project baseline and end date can be now preset or automatically calculated and can be added, deleted or dragged by mouse.

Grid
Added JSON data format as alternative to XML. It is supported for both download and upload.
Added attribute Rotate to rotate cell text (especially column header) by 90 or 270 degrees.
Added API method SetFilter to add one or more independent custom filters.

New compiler
The compiler to compress main file GridE.js was rewritten. Now the GridE.js file is smaller and is faster decompressed.
Source code owners now can also control settings for speed/size ratio and try/catch removing for debugging purposes.

TreeGrid JavaScript compiler is much more effective than all other known JS compilers, for example its produced code is about twice smaller than code from Packer and three times than YUI compressor.
If you purchased TreeGrid sources, never try to compress them by another compressor, especially uploading them to any online compressor is strictly prohibited!

See the online compiler.

Horizontal scrolling
Now TreeGrid can independently scroll all three column sections (left, middle, right). Users can also resize the section widths.
It is usable especially for Gantt to have independently scrolled the chart and the other cells.

According to the assigns resources can be calculated task and summary prices.
The texts in chart and task tips now can contain various information about the task or any custom texts.

The Gantt chart now can be based also on number units instead of dates. Including floating point and negative numbers. To use Gantt chart for interactive math charts.

Grid
Changes can be uploaded to server in order they were done by setting SaveOrder attribute.
Grouping can generate more levels according to one column, set by GroupChar attribute. For example the levels can be created for every part in URL path when set GroupChar='/'.
See File and directory example.

TreeGrid 6.3 released

We created two separate web sites for TreeGrid Gantt Chart at www.tgantt.com and original Editable JavaScript TreeGrid at www.treegrid.com.
Both components we sell together as TreeGrid with Gantt, the prices have not been changed and the component can be purchased in e-shop at any of the two domains.

TreeGrid 6.3 contains updates especially in Gantt chart.
TreeGrid now supports all standard Gantt chart features for project management or service management.

The algorithm for checking and correcting dependencies was rewritten, now works in the same way as in MS Project or Primavera.
The dependencies can be corrected automatically after any change in the chart (like task add, move, resize or delete or dependency change) or the incorrect dependencies can be marked in red and corrected later manually.
The dependencies now can be attached to main bar, flow or run bars.
The dependencies are now set in standard format "idtype+/-lag!span", e.g. 10, 10fs, 10fs+3, 10fs-2!0. The dependencies can be set as previous (ancestors) or next (descendants) or both (mirrored).
Added dependency span constraint (with ! on the end of dependency) to specify possible span between dependency start+lag and end. Usual values are 0 (no span, strict), and empty (unlimited span).
Now there can be defined two dependencies ss and ff between two tasks.
TreeGrid now checks all user inputs and changes if they do not violate some constraints, e.g. circular dependencies or end < start.

Added holidays as any excluded single or repeated dates (GanttExclude and GanttInclude attributes). The excluded dates are ignored in task and dependency calculations. They can be highlighted in chart or can be completely hidden from the chart.
Added baseline project date (GanttBase attribute). This date is used in Gantt calculations to not let tasks to start before or force the first tasks to start on.
Added task date constraints, early start (GanttMinStart), late start (GanttMaxStart), early finish (GanttMinEnd) and late finish (GanttMaxEnd).
The task date constraints are used during task move or resize and also during Gantt correcting dependencies. The task date constraints are displayed in Gantt chart as icons and can be added, deleted, moved or changed directly in the chart.

TreeGrid now supports fully smooth zoom. It is supported zoom from years to milliseconds. It is possible to define different header dates and background dates for every zoom level.
The zooming can be done in many ways: zoom to date range selected by mouse dragging in header, zoom to date clicked by mouse in header, right click to header for unzoom, click to buttons zoom in, zoom out, zoom to fit, select zoom level from combo.

The Gantt chart now can have defined both end and duration columns, their values are mirrored.
There are also many other changes in Gantt chart, see list of all changes

TreeGrid 6.3 also contains many minor updates and bug fixes in standard TreeGrid features, see list of all changes

Gantt Run boxes can be now set also by Start date + length and Start date + End date. The Run boxes can be set as independent (not continuous).
OnGanttChanged was extended, now it returns both original and new values and type of change (e.g Resize, Move, Delete, ...).
Added cell attribute GMT to show local and GMT dates in the same grid in different cells or columns.
Now the calendar / datepicker dialog can be called also by API function ShowCalendar for custom usage outside grid.

Added examples for all basic server script (ASP.NET/PHP/JSP) for loading and saving Gantt chart from and to database and for saving Gantt chart to XML file.
Added PHP framework for MySQL.
