Vlad, 

the xmlDataGrid is bound by  ItemList amd I do not specify any fieldname and therefore I can't use FieldLayout.Settings

<igDP:XamDataGrid Grid.Row="1" Margin="5,5,8,0"  Name="xamDataGridDrillDown" 
                              DataSource="{Binding Path=ItemList}" />

Thanks!

Steve

Hello Steve,

You can do the same in the code behind them, but you have to make sure that the fieldlayout of the child records is initialized. You can do this, for example, in the FieldLayoutInitialized event and check if it is the [1] layout and set the property.

xamDataGrid.FieldLayouts[1].Settings.LabelLocation = LabelLocation.Hidden;
