ASP.NET DataSet - Hierarchical Excel Export

We have a SharePoint Application that binds a [login to view URL] DataSet to SharePoint JS Grid. It includes hierarchical data: A task list with different outline levels. We now want to enable the user to export this task list to Microsoft Excel. The export should show the task list grouped by each outline level. The JS Grid can only export task in a flat list. So we are looking for a third party control like the Telerik RadGrid which can bind against the DataSet and export list so that it looks nicely formatted in Excel. Please bid, if you have a solution for this. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
