在上面搭建好DevExpress的环境后，要使用其GridControl控件。

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;
