My program uses TreeGridView library
(http://blogs.msdn.com/markrideout/archive/2006/01/18/new-link-for-treegridview.aspx).
Here contains test samples. I build it on MonoDevelop 2.0 Beta1 (1.9.2). On MS
Windows XP it's work correctly. On Linux I get the following Exception:

Unhandled Exception: System.InvalidOperationException: Visual Styles are not
enabled.
  at System.Windows.Forms.VisualStyles.VisualStyleRenderer.SetParameters
(System.String className, Int32 part, Int32 state) [0x00000] 
  at System.Windows.Forms.VisualStyles.VisualStyleRenderer..ctor (System.String
className, Int32 part, Int32 state) [0x00000] 
  at System.Windows.Forms.VisualStyles.VisualStyleRenderer..ctor

  at (wrapper remoting-invoke-with-check) AdvancedDataGridView.Form1:.ctor ()
  at AdvancedDataGridView.EntryPoint.Main () [0x00000] 

Reproducible: Always

Steps to Reproduce:
1. Load project
2. Build project
3. Run Test samples ("Simple Test App" or "TreeGridView Test App")
Actual Results:  
Unhandled Exception: System.InvalidOperationException: Visual Styles are not
enabled.
