Hi sjnaughten: 

I implemented the extended class SetInitialSortOrder for sorting a single column and it works will when the column that needs to be sorted is not a foreign key, otherwise it throws an exception. 

Also, when modifing this implementaion to sort multiple columns, I ran into an issue with defining more than one column in the DisplayColumn annotation.  It throws and exception and does not like this.

Is there a known solution for this? 

Thank you for your assistance.
