I want each band in the grid to have a default column sort set as soon as it opens. I tried using the Band_initialize event server side with:

e.Band.Behaviors.Sorting.SortedColumns.Add("ActionNo", Infragistics.Web.UI.SortDirection.Ascending);

but I get an error internal to the grid (object not set). Am I doing this incorrectly, and is there a javascript method to do this client side then?

I have a three level grid, and need a specific column sorted in each band.
