Hi Support, 

Look at this stack:
http://screencast.com/t/NmJiNDc1ZW

I've tried:
1) Setting the DataGrid to read only
2) Column to read only
3) binding to ignore DataErrors

   <telerik:GridViewDataColumn Header="Country" UniqueName="Country" 
                                                    IsReadOnly="True"
                                                    DataMemberBinding="{Binding Country.Name,ValidatesOnDataErrors=False}">
                        </telerik:GridViewDataColumn>

Nothing seems to prevent the call (completelly unnecesary IMHO) to IDataErrorInfo.

I consider this to be a mayor problem.


Notes: 
  • I can't find ValidatesOnDataErrors @ RadGridView level. (only available for silverlight?) 
  • Using latest WPF version : 2010.2.812.35

thanks in advance, 
Sebastian Talamoni

OK, just for the records , it's fixed in: RadControls_for_WPF_40_2010_2_0903 only when using ValidatesOnDataErrors="None" in the Grid.

I've tried to set it only in the column but the validation still got executed (so it's not working as expected at column level) 
   <telerik:GridViewDataColumn Header="Country" UniqueName="Country" 
                                              IsReadOnly="True" ValidatesOnDataErrors="None"
                                              DataMemberBinding="{Binding Country.Name}">
  </telerik:GridViewDataColumn>

P.S. I've updated your Telerik points accordingly.
