  Hello ,
  In our application we use RadDataForm to display some properties of an object(the data source object). Everything works fine, but when running the application we have spotted that two binding errors occurs. The binding errors occurs even if we don't set any proprieties of RadGridView. Below is the code we have tested(an empty default control):
  

  <telerik:RadDataForm >

  </telerik:RadDataForm >

  
  The bindin errors:
  System.Windows.Data Error: BindingExpression path error: 'CommitButtonVisibility' property not found on 'Client.Silverlight.ViewModels.ReferenceWorkspaceViewModel' 'Client.Silverlight.ViewModels.ReferenceWorkspaceViewModel' (HashCode=44903457). BindingExpression: Path='CommitButtonVisibility' DataItem='Client.Silverlight.ViewModels.ReferenceWorkspaceViewModel' (HashCode=44903457); target element is 'Telerik.Windows.Controls.RadButton' (Name='PART_CommitButton'); target property is 'Visibility' (type 'System.Windows.Visibility')..
  System.Windows.Data Error: BindingExpression path error: 'CancelButtonVisibility' property not found on 'Client.Silverlight.ViewModels.ReferenceWorkspaceViewModel' 'Client.Silverlight.ViewModels.ReferenceWorkspaceViewModel' (HashCode=44903457). BindingExpression: Path='CancelButtonVisibility' DataItem='Client.Silverlight.ViewModels.ReferenceWorkspaceViewModel' (HashCode=44903457); target element is 'Telerik.Windows.Controls.RadButton' (Name='PART_CancelButton'); target property is 'Visibility' (type 'System.Windows.Visibility')
  
  Please help to fix the errors.
  Thank you.

  Hi Alexander,
  
  Thanks for mentioning this issue. This is a known problem. Due to dynamic (late) setting of the DataContext in some elements in the visual tree of RadDataForm, it generates these exceptions.
  We are going to take care of the problem as though harmless it is indeed annoying.
  Meanwhile I may guarantee that this will not impact the behavior or cause any bugs while using the control.
  I am going to take care for a fix to be included in one of the next LIBs.
  
  Kind regards,
  Pavel Pavlov
  the Telerik team

  What's the status of the fix for this? I'm still seeing this bug in version 2012.1.514.
