How to calculate DiagramSurface's bounds when width and height were not specified

Hello,

I have the following declaration for my DiagramSurface instance:

<ms:DiagramSurface Name="ds" BorderThickness="0,1,1,1" 
                   SnapLineDrawing="{StaticResource SnapLineDrawing}"
                   HorizontalSnapSpecifier="{ms:SnapToInterval 10}"
                   VerticalSnapSpecifier="{ms:SnapToInterval 10}"
                   Formatter="{StaticResource Formatter}"
                   ZoomMode="ControlMouseWheel"
                   ShowConnectionPoints="True" 
                   SelectionMode="Extended"
                   SelectedElementChanged="ds_SelectedElementChanged" />

i.e. Width and Height properties are not specified and dimensions of the surface are adjusted to bounds of the window, as I understand. But when I try to get the surface's size (ds.Width or ds.Height), I get NaN values.

Is it possible to get actual size of the surface if its bounds were not specified?

Hello Dmity

When you do not specify the width and height of a WPF visual (such as our DiagramSurface), the Width and Height properties are set to NaN to indicate to layout panels that the visual should be auto sized.

You'll want to look at the ActualWidth and ActualHeight properties to get the pixel dimensions of the DiagramSurface.

Hello Jason!

Thank you! That's what I need exactly!
