I have two UltraWebGrids on my page.  The first grid exports just fine but when I try and export the second grid and have it start at column "KT" it starts at 0.  What I have found is that even though I am using Excel 2007 along with Infragistics35 10.2 it will not start past 256 columns, if I start at a column below 256 it works fine but that will not work for me because my first grid goes beyound the 256 to column "KS".  The reason I am using 2 grids is because the grid itself will not allow as many columns as I need, 500+ columns.
