Thank you for writing.
I would like to clarify what we support from Coded UI tests - we support Basic Record and Playback, but we do not support Rich Property Validation and Intent Aware Actions, because we do not provide yet a Coded UI MSAA plug-in for MS Visual Studio that should be developed for this kind of scenario. I am afraid that currently I cannot propose a workaround for this.
For more information, please read these blog posts about Coded UI Test Extension for 3rd party Windows Forms controls:
