Use the Columns property to access the collection of columns in the View. You can add, move, and delete columns. You can also access individual columns using indexer notation or by the bound field name.
using DevExpress.XtraGrid.Columns;
// Gets the first column in the Columns collection.
GridColumn colFirst = gridView1.Columns[0];
// Gets the column by its bound field name.
