实现

首先在窗体中拖拽一个GridControl

然后在窗体的Load时事件中对其进行添加列和样式设置

private void FrmSearch_Load(object sender, EventArgs e)        {            //设置GridControl样式            Common.GridControl.GridControlHelper.SetStyles(this.gridControl1.MainView as DevExpress.XtraGrid.Views.Base.ColumnView);            //订阅行点击事件            this.gridView1.RowClick += gridView1_RowClick;        }

进入设置样式的方法

public static void SetStyles(DevExpress.XtraGrid.Views.Base.ColumnView view)        {            if (view is DevExpress.XtraGrid.Views.Grid.GridView)            {                DevExpress.XtraGrid.Views.Grid.GridView gridView = view as DevExpress.XtraGrid.Views.Grid.GridView;                gridView.OptionsView.ShowGroupPanel = false;                                              //隐藏最上面的GroupPanel                gridView.OptionsView.ShowIndicator = false;                                               //隐藏指示列                gridView.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.None;           //设置焦点框为整行                gridView.OptionsSelection.EnableAppearanceFocusedCell = false;                                  //禁用单元格焦点                gridView.OptionsSelection.EnableAppearanceFocusedRow = true;                                    //启用整行焦点                gridView.OptionsSelection.EnableAppearanceFocusedRow = true;                                    //启用整行焦点                gridView.OptionsSelection.EnableAppearanceHideSelection = false;                gridView.OptionsView.EnableAppearanceEvenRow = true;                                            //启用偶数行背景色                gridView.OptionsView.EnableAppearanceOddRow = true;                                             //启用奇数行背景色                //gridView.Appearance.EvenRow.BackColor = System.Drawing.Color.FromArgb(150, 237, 243, 254);      //设置偶数行背景色                //gridView.Appearance.OddRow.BackColor = System.Drawing.Color.FromArgb(150, 199, 237, 204);       //设置奇数行背景色                //gridView.Appearance.FocusedRow.BackColor = System.Drawing.Color.Red;                //gridView.Appearance.SelectedRow.BackColor = System.Drawing.Color.Red;            }            //禁用自动生成列            view.OptionsBehavior.AutoPopulateColumns = false;            //禁用自动列宽            if (view is DevExpress.XtraGrid.Views.Grid.GridView)            {                (view as DevExpress.XtraGrid.Views.Grid.GridView).OptionsView.ColumnAutoWidth = false;            }            //禁用数据过滤面板            view.OptionsView.ShowFilterPanelMode = DevExpress.XtraGrid.Views.Base.ShowFilterPanelMode.Never;            #region 添加列            view.Columns.Clear();            int index = 0;            DevExpress.XtraGrid.Columns.GridColumn col = null;            col = new DevExpress.XtraGrid.Columns.GridColumn();            col.FieldName = "DBName";            col.Caption = "数据库名";            col.Width = 200;            col.VisibleIndex = index++;            view.Columns.Add(col);            col = new DevExpress.XtraGrid.Columns.GridColumn();            col.FieldName = "ShortNodeText";            col.Caption = "文件名";            col.Width = 200;            col.VisibleIndex = index++;            view.Columns.Add(col);            col = new DevExpress.XtraGrid.Columns.GridColumn();            col.FieldName = "CreateDate";            col.Caption = "创建日期";            col.Width = 130;            col.VisibleIndex = index++;            view.Columns.Add(col);            col = new DevExpress.XtraGrid.Columns.GridColumn();            col.FieldName = "TaskFile";            col.Caption = "任务文件";            col.Width = 180;            col.VisibleIndex = index++;            view.Columns.Add(col);            col = new DevExpress.XtraGrid.Columns.GridColumn();            col.FieldName = "FullPath";            col.Caption = "完整路径";            col.Width = 180;            col.VisibleIndex = index++;            view.Columns.Add(col);            col = new DevExpress.XtraGrid.Columns.GridColumn();            col.FieldName = "Barcode";            col.Caption = "电池条码";            col.Width = 180;            col.VisibleIndex = index++;            view.Columns.Add(col);            #endregion            SetAllowEdit(view, false);                                          //禁用编辑            SetAllowSort(view, DevExpress.Utils.DefaultBoolean.False);          //禁用排序            SetAllowFilter(view, false);                                        //禁用数据过滤        }

在上面方法中进行样式的设置以及列的添加

注意在添加列时FieldName 属性要与将来设置数据源时的字段一致。

然后上面的禁用编辑的方法

public static void SetAllowEdit(DevExpress.XtraGrid.Views.Base.ColumnView view, bool isAllow)        {            foreach (DevExpress.XtraGrid.Columns.GridColumn col in view.Columns)            {                col.OptionsColumn.AllowEdit = isAllow;            }        }

禁用排序的方法

public static void SetAllowSort(DevExpress.XtraGrid.Views.Base.ColumnView view, DevExpress.Utils.DefaultBoolean value)        {            foreach (DevExpress.XtraGrid.Columns.GridColumn col in view.Columns)            {                col.OptionsColumn.AllowSort = value;            }        }

禁用数据过滤的方法

public static void SetAllowFilter(DevExpress.XtraGrid.Views.Base.ColumnView view, bool isAllow)        {            foreach (DevExpress.XtraGrid.Columns.GridColumn col in view.Columns)            {                col.OptionsFilter.AllowAutoFilter = isAllow;                col.OptionsFilter.AllowFilter = isAllow;            }        }

初始化完样式和添加列后就要设置数据源

首先新建一个实体对象，对象要有与上面添加列时FieldName 所对应的属性。

下面是部门字段和属性，其他省略

public class DataTreeNode    {        private string id;        private string parentId;        private string nodeText;        private string createDate;        private string fullPath;        private string taskFile;        private string barcode;        private DataTreeNodeTypes nodeType = DataTreeNodeTypes.Folder;        /// <summary>        /// 去掉扩展名的数据文件完整路径        /// </summary>        public string Id        {            get { return id; }            set { id = value; }        }        /// <summary>        /// 父级节点的Id        /// </summary>        public string ParentId        {            get { return parentId; }            set { parentId = value; }        }        /// <summary>        /// 数据文件名称        /// </summary>        public string NodeText        {            get { return nodeText; }            set { nodeText = value; }        }     }

构建数据源

List<DataTreeNode> data = new List<DataTreeNode>();data = DataTreeListHelper.ParseDir(Common.Global.AppConfig.TestDataDir, data);var result = data.Where(p => p.NodeType = = DataTreeNodeTypes.File);

首先声明上面实体对象的List，然后使用ParseDir方法将文件目录进行递归查询。

然后进行筛选出文件类型。

然后可以直接设置数据源

this.gridControl1.DataSource = result;
