 设置DataGrid CanUserAddRows="True",自动添加一行。

控制当前row为新增行时不能删除

IEditableCollectionView editableCollectionView = dgDrug.Items;
if (editableCollectionView.IsAddingNew)
　　return;

　　

 　　　　private void BtnDeleteDrug_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                var entity = ((Button)sender).Tag as CoPaymentSchemeItemPriceEntity;
                if (entity == null || entity.EntityDataRow == null)
                    return;
                IEditableCollectionView editableCollectionView = dgDrug.Items;
                if (editableCollectionView.IsAddingNew)
                    return;
                ViewModel.Model.CoPaymentSchemeItemDrugPriceList.Remove(entity);
            }
            catch (PresentationException pex)
            {
                pex.Report();
            }
            catch (Exception ex)
            {
                new PresentationException(ex).Report();
            }
