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;
