在gridcontrol1 里面的gridview1里面有个事件

添加非绑定列

// 创建一个非绑定列 

GridColumn unbColumn = gridView1.Columns.AddField("非绑定属性列"); 

unbColumn.VisibleIndex = gridView1.Columns.Count; 

unbColumn.UnboundType = DevExpress.Data.UnboundColumnType.Decimal; 

// 禁止编辑 

unbColumn.OptionsColumn.AllowEdit = false;

// 为非绑定列设置数据

private void gridView1_CustomUnboundColumnData(object sender, CustomColumnDataEventArgs e) 

{

 if (e.Column.FieldName == "非绑定属性列" && e.IsGetData) e.Value = "";

 }
