I have installed version 1.0.2 beta in order to test a bug that was apparent with version 1.0.1.

There are a couple of unusual behaviours that I wanted to check. Firstly, I have a diagram within a ScrollViewer. All alignment settings are defaulted and with version 1.0.1, the diagram filled the area (it is filling out a single row/column within a Grid). The newer version doesn't and there is a 'Bounds' property that seems to constantly be reset to:
0,0,793.700787401575,1122.51968503937
which is causing the drawing control to become a fixed size.

I also had some code that resized the drawing based on the extent of the nodes and the zoomfactor of the drawing that worked beautifully with 1.0.1. Now, the BackBrush doesn't repaint the new area of the diagram when it is resized.

I am not sure if these are actual problems as it is obviously beta however I just wanted to find out as I am trying to build a prototype for demonstration purposes at the moment and the beta version appears to be causing some issues.

Thanks,

Eric

This might happen because we changed the Diagram base type from Canvas to ContentControl. By default Canvas does not clip its content, so the background brush fills all available space. Now the ContentControl clips its content at the Bounds rectangle so the background won't fill the whole scroll viewer if the diagram is smaller than it. Try either setting the scrollviewer's Background to the same brush, or make Bounds at least as large as the viewer.

I hope that helps,
