<Style x:Key="grdStudyListDataGridRowStyle" TargetType="{x:Type DataGridRow}"> <Setter Property="SnapsToDevicePixels" Value="true"/> <Setter Property="Validation.ErrorTemplate" Value="{x:Null}"/> <Setter Property="ValidationErrorTemplate"> <Setter.Value> <ControlTemplate> <TextBlock Foreground="Red" Margin="2,0,0,0" Text="!"
