Question : Limiting a DataGrid in WPF with ComboBoxes...

What is the best way to limit a datagrid in WPF? Right now I am trying to use comboBoxs I am open to other ideas.

I have a DataGrid that populates from a dataset.
the dataset has 7 columns 5 of them need to be limited by selecting items in the comboboxes

I've tried this, but it doesn't seem to work.
Throws the error "'System.Windows.Data.BindingListCollectionView' view does not support filtering."

Where am I going wrong?

        { 
            IconUtilityDataSet.IconInfoRow row = e.Item as IconUtilityDataSet.IconInfoRow; 
            if (row == null) 
                e.Accepted = false; 
            else 
            { 
                // Blah... 
            } 
        }
