Customizing items in DataGridViewComboBoxEditingControl

[primem0ver]

I have a DataGridView that is bound to the following class:


public class InfoControlClientData
{
public string Name { get; private set; }
public string Description { get; private set; }
public RequestFormat InfoFormat { get; set; }
public PositioningFlags StartingLocation { get; set; }

[Browsable(false)]
internal AllowedFormats AllowedFormats { get; private set; }


public InfoControlClientData(string name, string description, AllowedFormats formats)
{
Name = name;
Description = description;
AllowedFormats = formats;
}

}


Both the "InfoFormat" and the "StartingLocation" items are associated with DataGridViewComboBoxColumn's. Their corresponding data types are enumerations. I need to remove items in these boxes because not all items in the enumeration are meant to be select-able. For the last column, the same items need to removed from all boxes. For the items in the InfoFormat ComboBox, removal is based on the AllowedFormats Property of the class (which is a flags enum). So basically I need to remove any item from this combobox whose corresponding flag (bit) is not set to 1.

I was hoping to do this for all items in the list after the list is bound but before it is shown. Unfortunately I can't do this using the EditingControl property because this only returns a ComboBox when it is being edited. Is it possible to do this easily with a DataGridView? Will I need to add each row manually? Or do I need to use something else?
