Hi Theofilos,Thank you for contacting Syncfusion Support.In SfDataGrid each of child contains DataGrid. Please refer the below screen shot, Your requirement can be achieved by checking the AddNewRowIndex based on SelectedDetailsViewGrid of SfDataGrid. Please refer the below code snippet, 




private void FirstLevelNestedGrid2_RowValidating(object sender, RowValidatingEventArgs e) 
{ 
            //check the AddNewRowIndex for SelectedDetailsViewGrid in SfDataGrid 
            if (dataGrid.SelectedDetailsViewGrid.IsAddNewIndex(e.RowIndex)) 
            { 
                e.IsValid = false; 
            }
