Why I load diagram the whole picture zoom in first the zoom out?

[Jonathan]

hello,when I load diagram use code like this:

                    StreamReader streamReader = new StreamReader(diagramXmlFile);
                    string data = streamReader.ReadToEnd();
                    streamReader.Close();
                    this.ProjectImageDiagram.Load(data);

                    RadDocumentPane diagramPane = new RadDocumentPane();
                    DataTemplate doctabTemplate = (DataTemplate)CRWindow.TryFindResource("doctab");
                    StackPanel docTab = (StackPanel)doctabTemplate.LoadContent();
                   diagramPane.Header = docTab;
                   UserControl diagramUserControl = new UserControl(diagram, true);
                   diagramPane.Content = diagramUserControl;

And I add diagramPane to RadDocking-DocumentHost-RadSplitContainer-RadPaneGroup, but when I run the program and open this pane, I find that the diagram is zoom in first, and then zoom out to fit the window,why?   Hope to answer, Thanks !

Hi,

I tried to reproduce this unexpected behavior using the information provided but to no avail. There is not enough info about the diagram's properties set. Attached is the sample project I worked on. Please feel free to make any changes to it and send it back to us so we can reproduce the issue locally. You could also provide a sample runnable project of your own. As this is a forum thread you will need to use a third party web site for files sharing.

Something you could try is to set the diagram's AutoLayout  property to True.
