In the Swimlane diagram example (Data Visualization -> Diagrams -> Swimlane) the application crashes, showing at least one but often more than one error message.
How to reproduce:
- Open the Swimlane example.
- Click the area that is labelled as "Process name" (also marked in the attached screenshot)
- One or multiple Message boxes containing the exception message
{DependencyProperty.UnsetValue} is not a valid value for the Property "Background"pop up (see other screenshot)
Add a RotationAngle property or a Rotate() method or something similar that will automatically update the rotation of the ManipulationAdorner along with the shapes inside.
Add an option to modify the StartPoint and EndPoint properties of RadDiagramConnection instances via the SettingsPane.
This functionality can be achieved by modifying the default ControlTemplate of the SettingsPaneView element to include an additional RadTabItem instance in the RadTabControl element. In the additional RadTabItem, input controls can be used, such as the RadNumericUpDown element. These elements should modify properties that will be present in a custom LinkViewModelBase<NodeViewModelBase>> class. More specifically, the X and Y properties of the StartPoint and EndPoint properties of the RadDiagramConnection element.
The attached sample project shows the implementation of the above approach for achieving this requirement.
Add an option to customize the available colors in the SettingsPane control:
Hi,
In project we have noticed that sometimes for RadDiagram.ConnectionManipulationCompleted we receive unexpected values in event.
This problem is not systematic but it occurs often at the drag of new connection.
To make it reproducible for you I used CustomConnectors sample project from Diagram.
For easier analysis I recorded a video with bug and changes to CustomConnectors project.
Best regards,
Bartosz
NullReferenceException is thrown when trying to save RadDiagram instance that contains a RadDiagramShape with its Geometry assigned to a GeometryGroup value.
To work this around, you can flatten the GeometryGroup before setting the shape's Geometry property. This is done by calling the GetFlattenedPathGeometry() method of the GeometryGroup.
shape.Geometry = group.GetFlattenedPathGeometry();
Most problematic issue when container can contains a container inside of it.
In mvvm demo project i modified load/save button to Clear diagram and display different content.
It works but after few click there is a recurrence call to update Z indices.
The reason to create such combination is to have hierarchy in diagram to display diagram from general view to detailed view.
Throw a more descriptive error that tells the concrete reason. In this case, the issue relates to the wrong TargetType of the Style.
To reproduce the error, it is enough to add a container node (ContainerNodeViewModelBase<NodeViewModelBase>) in the graph source and then to add a ContainerShapeStyle with a wrong TargetType. For example, use a type of Button.
This is reproducible only with the ConnecitonBridge property of RadDiagram set to Bow or Gap.
A possible workaround is to create a class that derives from RadDiagramConnection and override its CreateGeometry, where you can manually calculate and create the geometry of the connection line along with a connection bridge geometry.
