Value does not fall within the expected range

[Nikituki]

Hello,

I want to use RadDocking control. I'm trying to implement example from documentation:
http://www.telerik.com/help/silverlight/raddocking-getting-started2.html

But I have errors at lines with TextBlocks
"Value does not fall within the expected range"

What I do wrong?

I'm using Silverlight 4 + Windows 7 x64 + Visual Studio 2010 + RadControls_for_Silverlight4_2011_3_1020_Dev

P.S. Sorry for my bad English.
