實現

首先在窗體中拖拽一個GridControl

 

 

而後在窗體的Load時事件中對其進行添加列和樣式設置

private void FrmSearch_Load(object sender, EventArgs e)
        {
            //設置GridControl樣式
            Common.GridControl.GridControlHelper.SetStyles(this.gridControl1.MainView as DevExpress.XtraGrid.Views.Base.ColumnView);
            //訂閱行點擊事件
            this.gridView1.RowClick += gridView1_RowClick;

        }

 

進入設置樣式的方法

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;                                              //隱藏最上面的GroupPanel
                gridView.OptionsView.ShowIndicator = false;                                               //隱藏指示列

                gridView.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.None;           //設置焦點框爲整行
                gridView.OptionsSelection.EnableAppearanceFocusedCell = false;                                  //禁用單元格焦點
                gridView.OptionsSelection.EnableAppearanceFocusedRow = true;                                    //啓用整行焦點
                gridView.OptionsSelection.EnableAppearanceFocusedRow = true;                                    //啓用整行焦點
                gridView.OptionsSelection.EnableAppearanceHideSelection = false;

                gridView.OptionsView.EnableAppearanceEvenRow = true;                                            //啓用偶數行背景色
                gridView.OptionsView.EnableAppearanceOddRow = true;                                             //啓用奇數行背景色

                //gridView.Appearance.EvenRow.BackColor = System.Drawing.Color.FromArgb(150, 237, 243, 254);      //設置偶數行背景色
                //gridView.Appearance.OddRow.BackColor = System.Drawing.Color.FromArgb(150, 199, 237, 204);       //設置奇數行背景色
                //gridView.Appearance.FocusedRow.BackColor = System.Drawing.Color.Red;
                //gridView.Appearance.SelectedRow.BackColor = System.Drawing.Color.Red;

            }

            //禁用自動生成列
            view.OptionsBehavior.AutoPopulateColumns = false;
            //禁用自動列寬
            if (view is DevExpress.XtraGrid.Views.Grid.GridView)
            {
                (view as DevExpress.XtraGrid.Views.Grid.GridView).OptionsView.ColumnAutoWidth = false;
            }
            //禁用數據過濾面板
            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 = "數據庫名";
            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 = "建立日期";
            col.Width = 130;
            col.VisibleIndex = index++;
            view.Columns.Add(col);

            col = new DevExpress.XtraGrid.Columns.GridColumn();
            col.FieldName = "TaskFile";
            col.Caption = "任務文件";
            col.Width = 180;
            col.VisibleIndex = index++;
            view.Columns.Add(col);

            col = new DevExpress.XtraGrid.Columns.GridColumn();
            col.FieldName = "FullPath";
            col.Caption = "完整路徑";
            col.Width = 180;
            col.VisibleIndex = index++;
            view.Columns.Add(col);

            col = new DevExpress.XtraGrid.Columns.GridColumn();
            col.FieldName = "Barcode";
            col.Caption = "電池條碼";
            col.Width = 180;
            col.VisibleIndex = index++;
            view.Columns.Add(col);

            #endregion

            SetAllowEdit(view, false);                                          //禁用編輯
            SetAllowSort(view, DevExpress.Utils.DefaultBoolean.False);          //禁用排序
            SetAllowFilter(view, false);                                        //禁用數據過濾
        }

 

在上面方法中進行樣式的設置以及列的添加

注意在添加列時FieldName 屬性要與未來設置數據源時的字段一致。

而後上面的禁用編輯的方法

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;
            }
        }

 

禁用數據過濾的方法

 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;
            }
        }

 

初始化完樣式和添加列後就要設置數據源

首先新建一個實體對象，對象要有與上面添加列時FieldName 所對應的屬性。

下面是部門字段和屬性，其餘省略

 

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>
        /// 去掉擴展名的數據文件完整路徑
        /// </summary>
        public string Id
        {
            get { return id; }
            set { id = value; }
        }
        /// <summary>
        /// 父級節點的Id
        /// </summary>
        public string ParentId
        {
            get { return parentId; }
            set { parentId = value; }
        }
        /// <summary>
        /// 數據文件名稱
        /// </summary>
        public string NodeText
        {
            get { return nodeText; }
            set { nodeText = value; }
        }
     }

 

構建數據源

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

 

首先聲明上面實體對象的List，而後使用ParseDir方法將文件目錄進行遞歸查詢。

而後進行篩選出文件類型。

而後能夠直接設置數據源

this.gridControl1.DataSource = result;
