This is known and has been reported to R&D.
Unfortunately, the priority of this case is low and due to this I cannot
say if or when this will be solved.
The problem is related to the System.Windows.Controls.DataGrid and
different versions of .NET and tools/extensions to .NET.
If you have .NET v4.5 or later the "ValidatesOnNotifyDataError" property
will be added to xaml code of the DataGrid and this does not exist in .NET
v4.0 which is used when building and compiling an iX PC application.
This only happens if you import and use this control in a iX PC application
and has a later version of .NET (than v4.5) or some addons/tools for .NET,
due to this the priority is considered low.
The suggested work around is to use the System.Windows.Form.DataGrid.
Another solution could be to remove the "ValidatesOnNotifyDataError"
property manually in the xaml code, but the drawback is that the code will
be regenerated if you make any changes on the screen and the build error
will come back.
