實現

首先在窗體中拖拽一個GridControl

?

然后在窗體的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GroupPanelgridView.OptionsView.ShowIndicator = false;?????????????????????????????????????????????? //隱藏指示列gridView.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.None;?????????? //設置焦點框為整行gridView.OptionsSelection.EnableAppearanceFocusedCell = false;????????????????????????????????? //禁用單元格焦點gridView.OptionsSelection.EnableAppearanceFocusedRow = true;??????????????????????????????????? //啟用整行焦點gridView.OptionsSelection.EnableAppearanceFocusedRow = true;??????????????????????????????????? //啟用整行焦點gridView.OptionsSelection.EnableAppearanceHideSelection = false;gridView.OptionsView.EnableAppearanceEvenRow = true;??????????????????????????????????????????? //啟用偶數行背景色gridView.OptionsView.EnableAppearanceOddRow = true;???????????????????????????????????????????? //啟用奇數行背景色//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 = "創建日期";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);#endregionSetAllowEdit(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 屬性要與將來設置數據源時的字段一致。

然后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后就要設置數據源

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，然后使用ParseDir方法將文件目錄進行遞歸查詢。

然后進行篩選出文件類型。

然后可以直接設置數據源

this.gridControl1.DataSource = result;
