I have recently switched to Infragistics because I felt (and still do) that Infragistics offers the best suite of controls for WinForms development, based on working evaluations of other vendors' Winform controls.

For reports, I come from a Crystal reports background and generating reports with the Infragistics document engine is a different experience (e.g., no "banded" GUI for report design).  I have written a few exceptionally simple reports using Infragistics document engine with no problem, but some formerly easy reports with Crystal seem to be daunting with the document engine.  For example, below is a typical report specification representative of what would be given me for a new report, easy for me in Crystal, but (for me) a challenge with the document engine:

Inventory

Part <<PartNo>>  Unit of Measure <<UOM>> Description <<Descript>>

     Plant  <<PlantID>>

             Warehouse             On Hand                  On Order                                      Supply                     

             <<WID>>             <<OnHand>>     <<sum(Orders.Qty)>>     <<OnHand + sum(Orders.Qty)>>

There are subtotals for on-hand, on-order and supply at the warehouse level, as well as at the plant and grand total levels.  For reference, there are three different plants with multiple warehouses and over a thousand different inventory items.  Inventory control managers do not want to see information in a grid, they just want to click on a menu selection, enter parameters in a prompt, and print.

I have gone through the Infragistics documentation and sample code and have not found anything that addresses such an example. Of course, there is nothing that says I can't continue to use Crystal Reports anymore, but I do like a challenge and would like to use Crystal less (for other reasons, Crystal can be such a dog).  The subtotals and calculated column are not the issue for me, but rather the issue for me is the embedded "banding" or grouping of the different "levels" that wrap around rows of detail.

Any suggestions for coding such a report or are there references to examples of other multi-level reports for something like warehouse/inventory management using the Infragistics document engine?
