You'll need to go to the page for the Size class - http://msdn.microsoft.com/en-us/library/system.windows.size.aspx It's in WindowsBase.dll instead of PresentationCore.

Grid is UIElement and you need System.Windows.Size for UIElement.Measure - not System.Drawing.Size. See http://msdn.microsoft.com/en-us/library/system.windows.uielement.measure.aspx. Hi Lukas, Thanks for the info. I went to the page and it told me Namespace: System.Windows<http://msdn.microsoft.com/en-us/library/system.windows.aspx> Assembly: PresentationCore (in PresentationCore.dll) Therefore I ensured my code contained the two lines clr.AddReference("PresentationCore") from Systems.Windows import Size This gives me ImportError: Cannot import name Size giving the line numebr of the import line. Conclusion : I am missing something - and I don't know how to find it out. Well, UIElement.Measure is in assembly PresentationCore but System.Windows.Size structure is in assembly WindowsBase: http://msdn.microsoft.com/en-us/library/system.windows.size.aspx. This is the link in Parameters section of UIElement.Measure - availableSize parameter. -- -- Lukáš
