I have a report in visual studio from a program that I have coded. My problem is I want to sort my report by Department and then by SupplierName. However, my problem is that Department and SupplierName are in different datasets. So how do I sort with two different datasets? Right now my report just uses one dataset and in place of SupplierName it is SupplierID.
Report Example (AS IS):

Data Sets:

A possible solution is creating a dataset that combines both datasets.
Then just create your table with the same column headers and add your two sorts.
To add the dataset just Rightclick on the project -> add new item -> data -> dataset
I believe this would be the only way since the DataSets are associated to the Tables and any one table can only have one dataset.
Hope this helps.
