The WebHierarchicalDataSource makes it easy to tie your multiple flat data sources into hierarchical relationships with its Visual Studio® 2008/2010 designer wizard.
Integrate Disperse Data
WebHierarchicalDataSource works with existing ASP.NET data source controls like the SqlDataSource. Integrate your data into a single consolidated, hierarchical view, whether it comes from .NET objects or relational databases.
Leverages the proven ASP.NET Data Source pattern and serves as an adapter of flat data sources into hierarchical form.
Connect with an Infragistics hierarchical view or one that comes with the Visual Studio toolbox; the WebHierarchicalDataSource is set up to serve data to either.
