Devexpress datagrid动态添加显示指定列的gridView

代码如下：

  public class DXGridControlHelper
    {
        /// <summary>
        /// 获取显示指定列的GridView
        /// </summary>
        /// <param name="grid"></param>
        /// <param name="columns">列集合</param>
        /// <returns></returns>
        public static DevExpress.XtraGrid.Views.Grid.GridView GetColumnsView(DevExpress.XtraGrid.GridControl grid,
          List<GridColumnModel> columns)
        {
            DevExpress.XtraGrid.Views.Grid.GridView view = new DevExpress.XtraGrid.Views.Grid.GridView(grid);

            foreach (GridColumnModel item in columns)
            {
                DevExpress.XtraGrid.Columns.GridColumn column = new DevExpress.XtraGrid.Columns.GridColumn();
                column.FieldName = item.DataColumnName;
                column.Name = item.ColumnName;
                column.Caption = item.ColumnTitle;
                column.Visible = item.Visible;
                view.Columns.Add(column);
            }
           //下面指定分组，-1 为不分组 0，1，2....为分组顺序 （add的时候指定groupindex 无效，可能为列未在视图中初始化）
            for (int i = ; i < columns.Count; i++)
            {
                view.Columns[i].GroupIndex =columns[i].GroupIndex;
            }
            return view;
        }

       ///<summary>
        ///  设置按钮列
        /// </summary>
        /// <param name="dataColumnName">数据字段名</param>
        /// <param name="dataColumnName">数据字段名</param>

        public static void SetButtonColumn(
                            string dataColumnName, string btnText, string skinName, System.Drawing.Image image,
            DevExpress.XtraEditors.ImageLocation location,
                            DevExpress.XtraEditors.Controls.ButtonPressedEventHandler clickFunction, DevExpress.XtraGrid.Views.Base.BaseView view, ViewType viewType)
        {
            RepositoryItemButtonEdit rib = new RepositoryItemButtonEdit();

            rib.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.HideTextEditor;
            rib.Buttons[].Kind = DevExpress.XtraEditors.Controls.ButtonPredefines.Glyph;
            rib.ButtonClick += clickFunction;
            rib.Buttons[].Caption = btnText; 

            if(skinName!="")
            rib.LookAndFeel.SkinName = skinName;

            rib.LookAndFeel.UseDefaultLookAndFeel = false;

            if (image != null)
            {
                rib.Buttons[].Image = image;
                rib.Buttons[].ImageLocation = location;
            }

            rib.Buttons[].Visible = true;

            switch (viewType)
            {
                case ViewType.GridView:
                    (view as DevExpress.XtraGrid.Views.Grid.GridView).Columns[dataColumnName].ColumnEdit = rib;
                    break;
                case ViewType.BandView:
                    (view as DevExpress.XtraGrid.Views.BandedGrid.BandedGridView).Columns[dataColumnName].ColumnEdit = rib;
                    break;
                default:
                    break;
            }
        }
    }

    public enum ViewType
    {
        GridView,
        BandView
    }

    }

    /// <summary>
    /// 动态创建gridView视图，列的Model
    /// </summary>
    public class GridColumnModel
    {
        /// <summary>
        /// 列表头文本
        /// </summary>
        public string ColumnTitle { get; set; }

        /// <summary>
        /// 列唯一标识 name,默认为(column_sql语句中的字段名（小写）)
        /// column_sqlcolumnname
        /// </summary>
        private string _columnName;
        public string ColumnName
        {
            get
            {
                if (string.IsNullOrEmpty(_columnName))
                    return "column_" + DataColumnName.ToLower();
                return _columnName;
            }
            set { _columnName = value; }
        }

        /// <summary>
        /// sql 语句中的字段名称
        /// </summary>
        public string DataColumnName { get; set; }

        /// <summary>
        /// 可见性，默认true
        /// </summary>
        private bool? _visible;

        public bool Visible
        {
            get
            {
                if (_visible == null)
                    return true;
                return bool.Parse(_visible.ToString());
            }
            set
            {
                _visible = value;
            }
        }

        /// <summary>
        /// 分组，默认-1
        /// </summary>
        private int? _groupIndex;
        public int GroupIndex
        {
            get
            {
                if (_groupIndex == null)
                {
                    _groupIndex = -;
                }
                return int.Parse(_groupIndex.ToString());
            }
            set
            {
                _groupIndex = value;
            }
        }

    }

使用该代码 方法：

说明：动态制定的列 要与数据源中的列字段名(sql语句中的字段名) 一致

 var view2 = DXGridControlHelper.GetColumnsView(gridControl1, new List<ColumnModel>() {
                        new ColumnModel(){ColumnTitle="ID",DataColumnName="Id"},//默认该列为显示，列名为column_id
                        new ColumnModel(){ColumnTitle="课件名称",GroupIndex=,DataColumnName="Name"},//按照该列分组
                        new ColumnModel(){ColumnTitle="描述",DataColumnName="Description"},
                        new ColumnModel(){ColumnTitle="归属",DataColumnName="Objective"},
                        new ColumnModel(){ColumnTitle="图片",ColumnName="img",DataColumnName="ImgGif",Visible=false}
                    });
                  DataTable tab = cl.GetDataTable("select * from table_name");
                   gridControl1.MainView = view2;
                   gridControl1.DataSource = tab;

end;
