First, you can set the DisplayFormat property to only the columns you want to display in the TextBoxArea. Second, you can set each Column Visible property in the Columns collections, so only columns you want will display in the Dropdown control.
e.g.:
winComboBox1.DisplayFormat = “%CompanyName%”;
winComboBox1.Columns[ “CompanyID” ].Visible = false;
