The ExportToImage method of the RadDiagram control does not take into account transforms applied to the diagram items.

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

If two connections are crossing one another at a connection point, the connection bridge (bow or gap) is not drawn.
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.

   Now when i want to move the drawing in visual range,just by zoom in and zoom out ,if using the doument area like the microsoft visio,adding the A4 size design area(or B5,A3, and so on...),
we can zoom in and zoom out area by Ctrl+Mousewheel,can pan the drawing by scrollbar too.

The RadDiagramContainerShape class is quite limited as a container because it has a header, resizes to fit the content and has fixed padding around the borders for the children.

A simple base RadDiagramContainerShape that doesn't have a default style and doesn't impose any layout constraints on the children will be very useful to create custom containers to build nested shapes for UI design tools.

Thanks

Reason for Closing:
Changing the class the RadDiagramContainerShape inherits from will be a breaking change we cannot afford.
The mentioned customizations are possible via inheritance and custom styles.

Currently there is no straightforward way to notify that a point is added/removed from the ConnectionPoints collection of the RadDiagramConnection.

When user hovers a connector and pastes a connection, the pasted connection should be attached to the hovered connector.

You can check the Diagram SDK sample in GitHub - "PasteOnMousePosition" whic demonstrates this functionality.

We are marking this feature request as declined - the code in the SDK sample is the preferred way to go instead of built-in feature.
