What I want to know is that whether we can nest two or more DataTable to use as DataSource for a GridView.
I have a GridView where I want to display the list of training areas of a company and for each field I want to see a list of all courses that belong to that particular area using a GridView.
The solution, according to me, is to create a DataTable that serves the fields and in each field I create a DataTable powered by the associated training.
Unfortunately this solution did not work?
Do you have ideas or any suggestions to achieve this?
