Hi Stoyan,

I am using following code for overview window of diagram.

Code in XAML
<diagram:Overview x:Name="overview" FitAll="True" />

Code in XAML.cs
overviewWindow = new OverviewWindow();
                   overviewWindow.Owner = this;
                   overviewWindow.RenderSize = new Size(300, 300);
                   overviewWindow.Visibility = Visibility.Visible;
                   overviewWindow.Background = System.Windows.Media.Brushes.White;
                 
                                           overviewWindow.overview.Document = diagram;
                       overviewWindow.overview.Height = overviewWindow.Height;
                       overviewWindow.overview.Width = overviewWindow.Width;
                       overviewWindow.overview.HorizontalAlignment = HorizontalAlignment.Stretch;
                       overviewWindow.overview.VerticalAlignment = VerticalAlignment.Stretch;
                                           }


The above code channging Height and width of the overview  in accordance with window size.
But even if we are not changing window size , but we are changing the zoom factor of diagram , height and width of overview is also getting changed.
We want fixed size of overview irrespective of zoomfactor.

Please suggest for this.

It seems the overview does not allow the scale to be larger than 100%, even in FitAll mode, which would happen in your case. Our developer can't think of any particular reason why that limitation was added; we'll see if we can remove it for the next release.

I don't think this has anything to do with the overview. You can see the same effect if you start resizing a notepad window over the buttons below the diagram.

Using the "Overview window" project you emailed us for this and references to the v2.3 assemblies, I can see only the size of the tracker rectangle change when zooming out; it shows what part of the diagram is currently visible in the scrollviewer, so its size is expected to change.
