Hello,

Sure this is possible, one possible approach is

UltraWebGrid1.Columns.FromKey("CustomerID").Hidden = true;

However, there is one thing that may causes problem - the page lifecycle. When the grid rebinds, all colunms and row infomration is lost and data is loaded again, so you need to be sure that when you call the code above, your grid should already be bound with data and not rebound (reset) at a later point prior to showing the grid on the page.
