I have four invoke data instructions in Load() that are filtered and assigned to an IEnumerable but how would I display them on the same data grid?
You can only bind the DataGrid to a single, heterogeneous IEnumerable.
If I made a class that contained the four IEnumerables there is no way to display them by populating an IEnumerbale with my single object?
You need the data from the four IEnumerables in one single IEnumerable in order to show it in the DataGrid. After all it has only one Data property.
