GoXam releases: v2.1.*

This forum is for questions about our new diagramming controls for WPF and for Silverlight.

GoXam for WPF, a.k.a. GoWPF, requires .NET 3.5.

GoXam for Silverlight, a.k.a. GoSilverlight, requires Silverlight 4 [edit: earlier versions of Silverlight are no longer supported]

We are pleased to announce the availability of GoXam diagramming controls for WPF and for Silverlight.

For an overview, see GoXam Overview and related pages.

For installation kit downloads, go to Evaluation.

You can run the online demos and read the introductory document at www.GoXam.com.

In case you want to know about the latest bug fix releases for version 1.0, I thought I should post that information here.

25 April 2010: 1.0.8 (this is a very old version – please use the latest, in the last posts of this forum topic)

Version 1.0.8 is available as ZIP files containing only the DLL and release notes.
You’ll need to install the MSI kit first, to get all of the documentation and samples.

For Silverlight:
GoSilverlight 1.0.8 for Visual Studio 2008 and Silverlight 3
For WPF:
GoWPF 1.0.8 for Visual Studio 2008 and WPF 3.5

Changes since v1.0.1:

  • Better support in Overviews for observing changes to Part.Visible
  • Fixed DraggingTool.MoveParts to respect Part.CanMove()

Fixed bug in GraphLinksModel that did not update the membership of
links in groups when a node changed group membership or was delayed

  • Extended …Model.MakeNodeKeyUnique to handle null values when NodeKey type is String
  • Extended …Model.MakeNodeKeyUnique to create new Guids when NodeKey type is Guid
  • Added GraphLinksModelLinkData.LabelNode property, for built-in support of connecting links to links
  • Fixed null reference exception in CheckLinkValid
  • Fixed dynamically changing DataTemplates to avoid keeping hold of some old Nodes and Links
  • Fixed LayeredDigraphLayout exception with Orthogonal links before the DiagramPanel is realized
  • Fixed the disappearance of some nodes when the diagram is made visible again (GoSilverlight only)
  • Fixed initialization of GraphLinksModel.LinkCategoryPath to be
    “Category” when the LinkType is GraphLinksModelLinkData
  • Fixed Diagram.Start/Commit/RollbackTransaction not to signal an error if there’s no Model yet, to avoid design-time error with Overview
  • Fixed undo/redo bug recording changes during animated layouts

Version 1.1 is now available, for both WPF and Silverlight, and for both Visual Studio 2008 (.NET 3.5, Silverlight 3) and Visual Studio 2010 (.NET 4, Silverlight 4).

The latest kits are listed on the evaluation page.

Because Visual Studio 2010 supports targeting older platforms, the kits for Visual Studio 2010 include the DLLs for the older versions of the platforms (Silverlight 3 or WPF 3.5).

Major new features include support for Silverlight 4 or .NET Framework 4.0, the GridPattern panel, “DropOnto” behavior, and many new samples.

We have updated www.goxam.com to include online demos for both versions of both platforms. The online help has been updated too.

We’ll be updating our website gradually over the next few weeks.

6 February 2012: 1.3.2

Version 1.3.2 now supports Silverlight 5 and includes a number of significant new features and improvements. Download kits from our evaluation page.

This version has been superseded by a newer one – see the last post in this topic.

There is only one kit for Silverlight; it is intended for use for Visual Studio 2010. Although it targets Silverlight 5, it also includes another DLL if you are still targeting Silverlight 4. We do recommend upgrading to Silverlight 5 if you can.

There are two kits for WPF: one for Visual Studio 2008 and WPF 3.5, and one for Visual Studio 2010 and WPF 4.0.

Changes since v1.2.6:

Samples

  • Simplified samples to utilize Silverlight 4 features, such as declaring XML namespace as: xmlns:go=“http://schemas.nwoods.com/GoXam, just as in WPF, and thus not needing declarations for xmlns:golayout or xmlns:gotool
  • Added Gantt sample, demonstrating how to create a Gantt chart
  • Added PERT sample, demonstrating how to create a PERT diagram
  • Added Fishbone sample, demonstrating a custom layout for fishbone cause-and-effect diagrams
  • Added Virtualizing sample, demonstrating a VirtualizingPartManager and a VirtualizingDiagramPanel; also a VirtualizingTreeLayout
  • Improved the EntityRelationship sample to optionally show an in-place Print Preview
  • Improved the OrgChart sample scale Slider to use a logarithmic scale, for improved user control
  • Improved the SequentialFunction sample, demonstrating a tool that lets the user shift the endpoint of a link at a node
  • Added GoSilverlightMinimal and GoSilverlightBasic examples, demonstrating simple uses of GoXam Parts
  • Added Node.RotationSpot attached property
  • Added Node.ZOrder attached property, defaults to NaN (unspecified)
  • Improved Route.ComputeMidAngle when the standard ComputeMidPoint returns a point on a segment other than the middle one
  • Fixed some cases of initializing Group.IsExpandedSubgraph when initially not Visible
  • Fixed initial visibility of Links whose go:Part.Visible property is false
  • Fixed neglecting to update link routes when making some Links Visible Controls
  • Added DiagramPanel.CenterRect, to try to scroll a particular area to the center of the viewport
  • Added DiagramPanel.ZoomToFit overloaded methods, to change the Scale so that the DiagramBounds fits within the viewport
  • Added WPF PartManager.AddsToLogicalTree property to control whether Parts are added and removed from the logical tree; this is potentially useful for data-binding
  • Added WPF PrintManager.Paginate method, so that a DocumentPaginator can be used safely, for example for creating a print-preview functionality using an XPS DocumentViewer
  • Added PrintManager.PageInfo.PageBounds property
  • Added PrintManager.Completed event and OnCompleted protected virtual method, called after the print operation is finished
  • Added PrintManager.DoPrint protected virtual method, called from Print, to allow customization of print options, such as printer choice and printer fallback options in Silverlight 5
  • Printing now copies the value of Diagram.FlowDirection to the Canvas that is printed
  • Fixed initialization of Diagram.NodesSource to support OneWay data-binding of that DependencyProperty (and same for Diagram.LinksSource)
  • Improved scrolling of small diagram within the viewport
  • Fixed panning and diagram resizing to be limited to the DiagramPanel.DiagramBounds
  • Fixed left-over temporary nodes caused by drag-and-drop between Diagrams being interrupted by loss of focus due to switching applications
  • Fixed initial scale for Overview after setting Overview.Observed
  • Improved Overview memory retention and Box visibility when setting Observed = null

Layouts

  • Enhanced DiagramLayout.DoLayout to observe ArrangementOrigin
  • Added TreeAlignment.BusBranching
  • Added TreeLayout.ComputeBusNodeSpacing and ComputeBusLastRowSpacing methods
  • Fixed “Bus”-type TreeLayout to respect SetsPortSpot and SetsChildPortSpot
  • Fixed some cases where TreeLayout would depend unnecessarily on TreeVertex.Node being non-null
  • Fixed some cases of positioning when TreeLayout.Compaction=“None”
  • Fixed TreeLayout.AddComments to ignore non-Visible comment Nodes and TreeLayout.LayoutComments to route around the comments when they extend below the commented (parent) node
  • Fixed situation where changing a node’s containing group to or from null caused the Diagram.Layout to be invalidated even if its Conditions=“None”
  • Fixed external drop not causing automatic layout when there is no UndoManager
  • Improved automatic layout due to viewport size changes when there is layout animation
  • With improved Silverlight 4 XAML parser, can now set DiagramLayout Conditions="…" instead of ConditionFlags="…"

Models

  • Fixed GraphLinksModelNodeData, GraphModelNodeData, and TreeModelNodeData constructors to automatically create a new Guid for the Key if the KeyType is Guid

Tools, Commands

  • Added DraggingTool.MayAcceptData and AcceptData, to more easily accept external drag-and-drop data from outside of Silverlight
  • Changes to DiagramPanel.Scale, MinimumScale, and MaximumScale now update Commands that depend on those properties
  • Fixed CommandHandler.Ungroup to expand each group before ungrouping it
  • Fixed undo/redo creating/deleting a completely unconnected Link, in the DraggableLink sample
  • Added WPF CommandHandler.ClipboardBitmap property, when set to true causes CopyToClipboardto add a bitmap of the area of the diagram occupied by the copied parts to the system clipboard.

A complete list of new features is at this post: 1.3 New Features.

The release notes in each kit lists all of the changes, including both new features and bug fixes.

For version 1.3.3 we have created new installation kits. You can download the desired kit from our evaluation page. You’ll need to uninstall any existing installation of version 1.3.*.

Version 1.3.3 includes a number of bug fixes.

Changes since 1.3.2:

Samples
o Fixed missing templates for groups in the Piping sample

Parts
o Fixed bug to allow collapsing/expanding Node subtrees and Group subgraphs by changing the node data Category, thereby replacing the DataTemplate that presumably has the desired values of go:Node.IsTreeExpanded or go:Group.IsSubGraphExpanded
o Fixed visibility of offscreen Links re-created by changing templates
o Fixed orthogonal link jump-overs and jump-gaps when crossing precisely at a link point
o Fixed updating link jump-overs and jump-gaps after moving links without rerouting (because the moved selection effectively included those links)

Controls
o Improved auto-scrolling
o Fixed initial scale for Overview after setting Overview.Observed

Layouts
o Improved stack usage in recursive TreeLayout, to reduce likelihood of stack overflow

For version 1.3.4 we have created new installation kits. You can download the desired kit from our evaluation page. You will need to uninstall any existing installation of version 1.3.*.

Version 1.3.4 includes a few bug fixes and one new feature in GoSilverlight.

Changes since 1.3.3:

Controls
o WPF: Improved autoscrolling to always call DoMouseMove on the current tool, so that the tool gets a chance to update during the autoscrolling
o WPF: Fixed some cases where the diagram was temporarily clipped after calling DiagramPanel.MakeBitmap of a small diagram
o Silverlight: Added PrintManager.Starting event and OnStarting protected virtual method, called before the printing actually starts but after the printer has been chosen
o Silverlight: Fixed ability to print after cancelling a print

Models
o Fixed MakeNodeKeyUnique to automatically handle duplicate Guids correctly

Tools, Commands
o Fixed RelinkingTool.DoActivate to initialize both temporary nodes/ports even before DoMouseMove is called

Changes since 1.3.2:

Samples
o Fixed missing templates for groups in the Piping sample

Parts
o Fixed bug to allow collapsing/expanding Node subtrees and Group subgraphs by changing the node data Category, thereby replacing the DataTemplate that presumably has the desired values of go:Node.IsTreeExpanded or go:Group.IsSubGraphExpanded
o Fixed visibility of offscreen Links re-created by changing templates
o Fixed orthogonal link jump-overs and jump-gaps when crossing precisely at a link point

o Fixed updating link jump-overs and jump-gaps after moving links
without rerouting (because the moved selection effectively included
those links)

Controls
o Improved auto-scrolling
o Fixed initial scale for Overview after setting Overview.Observed

Layouts
o Improved stack usage in recursive TreeLayout, to reduce likelihood of stack overflow

For version 1.3.5 we have created new installation kits. You can
download the desired kit from our evaluation page. You will need to
uninstall any existing installation of version 1.3.*.

Version 1.3.5 includes several bug fixes.

Changes since 1.3.4:

Parts

o Fixed orthogonal links sometimes being clipped improperly along the borders

Controls

o Improved <b>DiagramPanel.SetScaleAndPosition</b> when animated scroll/zoom
o <b>Overview.BoxTemplate</b> now respects <b>go:Part.InDiagramBounds</b> to control whether the whole <b>Overview.Box</b> should be visible in the overview, or just the observed diagram
o Reduced likelihood of memory leaks when data-binding through <b>PartBinding.Part</b> or <b>VirtualLinkData</b>

Layouts

o Fixed bug in network.<b>AddNodesAndLinks</b> where links connecting to nodes in deeply nested groups would be ignored
o Layouts handle better the <b>Location</b> of a <b>Group</b> with an invisible <b>GroupPanel</b>
o Fixed positioning of very broad nodes when <b>TreeLayout.Compaction="None"</b>

Models
o Fixed model.CreateInitializedCopy to copy some properties that had been ignored

Changes since 1.3.3:

Controls
o WPF: Improved autoscrolling to always call DoMouseMove on the current tool, so that the tool gets a chance to update during the autoscrolling
o WPF: Fixed some cases where the diagram was temporarily clipped after calling DiagramPanel.MakeBitmap of a small diagram
o Silverlight: Added PrintManager.Starting event and OnStarting protected virtual method, called before the printing actually starts but after the printer has been chosen

Version 2.0.1 now supports Visual Studio 2012 and .NET 4.5.

You can download the desired kit(s) from our evaluation page.

Version 2.0.1 includes several bug fixes.

Changed since 1.3.5:

Parts
o Changing Part.Visible now remeasures any containing Group automatically
o Fixed showing grandchild Link when expanding tree within a Group when the grandchild Node was not expanded
o Collapsing or expanding “trees” no longer causes stack overflows when the diagram has cycles
o Silverlight: Improved some cases of rerouting member links when expanding Group that had never been expanded

Controls
o WPF: The PrintManager’s DocumentPaginator now sets the DocumentPage.PageSize

Layouts
o Fixed another case of TreeLayout with Compaction=“None” and very broad parents
o Reduced cases where a layout caused by a model change would result in a separate transaction
o The CircularLayout copy constructor did not copy all of the properties it should have

Models
o Fixed computing a group’s member links when adding a group after adding the subgraph node and link data to a GraphLinksModel

Tools, Commands
o Fixed position of rotate handle when RotationSpot is not Center

Version 2.0.2 is now available.

Changes since 2.0.1

Samples
o Improved the Virtualizing sample to make the VirtualizingTreeLayout more generally useful

Parts
o Route.MidAngle has been improved to not consider segments shorter than one unit if that is where the midpoint is – instead it uses the average angle of the adjacent segments
o Fixed cases of Link JumpOvers or JumpGaps being incorrect when scrolled in from offscreen

Controls
o External drags now autoscroll, just as internal drags do

Layouts
o Fixed LayeredDigraphLayout routing of Bezier Links connecting to visible Nodes inside nested Groups
