Release Notes VARCHART XGantt 5.1

Product VARCHART XGantt
Version 5.1
Edition .NET, ASP.NET, ActiveX
Date 4 December 2016

List of Enhancements

  • Automatic collapsing/expanding of groups now also possible when groups are being moved.
  • Several new sash attributes:
    • Three-dimensional display can be switched on/off.
    • The sash width can be specified.
  • The moving phantom of the sash can appear as double line.
  • The rubber rectangle for marking nodes can be switched off.
  • New interaction mode for moving the screen section by hand cursor (so-called panning mode).
  • New object VcViewComponent for setting attributes for each component individually.
  • Attributes for the layout of layers in work free areas can now be specified. For this, the Edit layer dialog was restructured and the API was enhanced by new properties.
  • The arrangement of nodes in a group and the collapsing state of a group can now be specified data-driven individually for each group.
  • New properties VcGantt.SnapTargetNodesSelectionMode and VcNode.SnapTargetMode. This enables to specify for each node individually whether it is to be a snap target for nodes being moved or not.
  • Three new layer shapes: vcRectangleTriangleLeft, vcRectangleTriangleRight, vcRectangleTriangleLeftRight.
  • New events: vcInteractionModeChanging and vcInteractionModeChanged
  • New method: VcLegendView.Update()
  • Snap lines and snap markings for visualizing snap targets at nodes.
  • New method VcDataRecord.IdentifyObject for identifying the object (node, link, group) representing the data record.
  • New property VcGroupLevelLayout.GroupsInvisible to specify whether the groups having been created from the VcGroupLevelLayout for the respective level are to be displayed or not. The visibility of groups can also be specified depending on a data field. For this, the following properties were added:
    • VcGroupLevelLayout.GroupsInvisibleMapName
    • VcGroupLevelLayout.GroupsInvisibleDataFieldIndex
  • New properties VcGantt.DraggingViaDiagramComponentAllowed, and VcGantt.DraggingViaTableComponentAllowed allowing to specify areas where drag & drop is activated.

List of Fixed Bugs

  • Calling VcGantt.Reset and reloading the data caused Error 13 Class 1720 when closing the application.
  • Using VcGantt.CombiningControlsEnabled=true (Multigantt) and calling the page preview with zoom factor = 100 % led to AccessViolationException.
  • The events OnInteractionStartComplete and OnInteractionObjectChangingComplete weren’t fired by XGantt ActiveX in a .NET application.
  • If an activity with duration = 0 days was dragged to a weekend, the end date was < start date.
  • VcGantt.ScrollToNode didn’t work when all groups were collapsed.
  • AutoSchedule and restriction dates caused problems.
  • Symbol layers didn’t snap according to the specified smallest time unit when being dragged horizontally.
  • Performance problems with ExtendedGroupingNodesOnSubLevelsAllowed set to NO.
  • Possible memory leak in WinForms XGantt control fixed.
