Other containers controls such as Canvas do not have virtualization support in .Net 3.0 &amp; 3.5. <P>Chris Lovett from Microsoft&nbsp;now wrote a great sample that shows how you can also virtualize&nbsp;a Canvas container control so it can efficiently host and scroll thousands of WPF elements without consuming huge amount of memory.&nbsp;&nbsp; <P>The provided down-loadable ZIP has a white paper and the code. <P>Hope you find this useful. <P>Jossef.</P><img src="http://blogs.msdn.com/aggbug.aspx?PostID=8116217" width="1" height="1">WPF Perfromance Virtualization
