I have a WHDG that I load from one dataset that has two tables.  I have autogeneratebands=true.  I cannot seem to hide the id column, which I need that value when using a hyperlink, which I also need to add in code behind.  The WHDG loads fine and so do the bands, I haven't even tried to add a template field yet.  I have tried to hide the first two columns in the band to no avail.  I have tried the RefreshBehaviors in the DataBound event after the rowisland.maingrid.columns[0].hidden=true; and I get an error like 'script controls may not be registered after pre-render.

I can't figure out how to hide a couple of the columns in my band.  I have tried to create the columns in html and setting autogeneratebands=false but  the bands will not load.
