    We are working on a custom GridViewBoundColumnBase class to support a 1:M list that will also participate in the filtering and grouping behaviors that you have built.

    This is Silverlight and in the end we wish simply to have one column that demonstrates something simliar to

    [   Group A, Group B, Group  F, Group L   ]
    Just text, and in this to teach the Filters that I might want to filter out rows that have groups containing "Group B", etc.

    Hello Rich,

    If your column is of type string, then you will be able to filter, sort and group on it, but the filtering, sorting and grouping logic will be like for any other string column. The filtering, sorting and grouping logic cannot have some additional semantic knowledge that your string is special and that it contains a comma delimited list of values. From the data engine's point of view this is juts a string -- it does not know what is inside it. 

    This is about as close as you can get to your requirement.
