Infragistics UltraWebGrid Rows Hidden After Databind

My Environment is as follows:
.NET 2.0 (Visual Studio 2005)
SQL Server 2005
Infragistics 2007.3 UltraWebGrid

Problem:
After binding data to the UltraWebGrid I cannot see any of the rows on the actual grid.  I can verify the following:

1.) There is data in the datatable being bound to the grid.  I can see it in the debugger.
2.) I see "Drag a column header here to group by that column" on the page rather than "No data to display" so I know that data is making it to the page. However the rows seem to be hidden.
3.) I implementing the grid in the exact same way on other pages and it seems to work fine.

My question is this:  Is there anything that would prevent the rows from being shown in the grid even though data is being bound to it?
