Hide the columns for members from parent class in grid

[Curious]

I have a derived class (DistributionItem) that contains a few members.
Now I have a binding list of instances of this class to be displayed
in a grid.

However, extra columns are displayed from the parent class
(IWorkerItemBase). How can I hide those members from the parent class
in the grid?

FYI, my code is below:

SortableBindingList<IWorkerItemBase> baseList =
worker.SelectedItems;

SortableBindingList<DistributionItem> distList = new
SortableBindingList<DistributionItem>();

foreach (IWorkerItemBase bse in baseList)
{

// Safe cast
DistributionItem dist = bse as DistributionItem;

if (dist == null)
{
return;
}

// If it's DistributionItem
distList.Add(dist);

}

c1FlexGrid1.DataSource = distList;

My first thought is to edit the tags and restrict what is shown there.

I did that by setting the columns in the grid properties. However, it
still loads extra columns including those in the parent class. It
seems that it ignores the properties of the grid set in the grid
properties dialog, once the datasource is set in the code.
