Visual CSharp .NET - UltraGrid Infragistisc

Hi, I'm trying to display an object data in an Infragistics UltraGrid Control (C#) by DataSourse property. And By now I Display it, but there's some attributes in that object I wouldn't like to display, or I don't want the user to see... but I have no idea about how to do so, can anyone help me out pls...???

this.grid.DataSourse; = arrObjects //Objects ArrayList
this.grid.DataBind();

I notices to the first sight that you are a wretched jackass.

It is a simple enough idiot. Only it conceals the columns that you do not wish that should be seen. Ignorant dirt.

this.grid.Columns[0].Visible=false;
