I have this datagrid in my program that pulls its rows based on a data relation from another datagrid on the same page. The database that I am pulling the information from comes from another program so I cannot really add tables and such. Anyways one of the items that comes into my list comes in as a number that represents something. I don't want the number to be shown. I want what it represents to be shown. Now I thought to make an xml file with the representations, and then add a realtion to my xml file but I can't seem to figure out how to implement it. Is this a good way to do this? How else might I accomplish such a task??
