I've looked at that information and the thing that I immediately notice is this list of "conditions" that they talk about:
1) All the columns specified in the datagrid must be present in both datasets.
2) The data type of all columns in the datasets must be the same.
3) The column names should match.
In my post, I did make mention of the fact that my data is dissimilar and that they don't match. I know that you can merge like data, but what I want to know is if you can merge unlike data.
