DevExpress,LayoutControl,TreeList,GridControl等
1.显示边框进行折叠
选择一个layoutControlGroupX 将其GroupBordersVisible设置成True,将TextVisiable=True
2. TreeList
2.1需要绑定的数据有ParentFieldName,KeyFieldName,
2.2.1.TeeList前面的连线
启动程序中添加DevExpress.BonusSkins.v13.1.dll
Main中进行注册
[STAThread] static void Main(params String[] args) { DevExpress.UserSkins.BonusSkins.Register(); DevExpress.Skins.SkinManager.EnableFormSkins(); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); if (args.Length>=1 && args[0]=="test") { Application.Run(new Form1()); }else { Application.Run(new F.Studio.DevExpressUI.frmLogin()); } }
需要设置LookAndFeel(比方Blue),
将UseDefaultLookAndFeel设置成False

treeList1.OptionsView.ShowCheckBoxes = true;

3.GridControl
添建按钮列->参考:http://www.cnblogs.com/zeroone/p/3534783.html
3.2 设置参考列:http://blog.csdn.net/nanchuan/article/details/7664070
gridView1.CustomColumnDisplayText += (s, e) => { if (e.Column.FieldName == "FuncConfigId") { var list = FuncsConfigLookUp.Value; if (list != null) { var it = list.FirstOrDefault(ent => ent.ConfigId == int.Parse(e.Value.ToString())); if (it != null) e.DisplayText = it.ConfigName; } } };
3.3 设置计算列，分组会总等
参考:http://blog.csdn.net/lenovouser/article/details/7405577
gridColumn1.UnboundType = DevExpress.Data.UnboundColumnType.Decimal;
gridColumn1.UnboundExpression = "[Amount] * ToDouble(SubString([CostPerUnit],0, CharIndex('(',[CostPerUnit])))";
gridView1.GroupSummary.Add(SummaryItemType.Sum, "gridColumn1", gridView1.Columns["gridColumn1"],"组计:{0}");
注:gridColumn1是一个未帮定列，另外需要开启gridView.OptionsView.ShowFooter=True
3.4判断gridControl 的那个列的单元格被双击
gridControl1.MouseDoubleClick += (s, e) => { if (e.Button == System.Windows.Forms.MouseButtons.Left) { GridHitInfo hInfo = gridView1.CalcHitInfo(new Point(e.X, e.Y)); if (!hInfo.InRow) return; //确保点的是数据行而不是标头 var ent = qSymptomRepositoryItemBindingSource.Current as Q_SymptomRepositoryItem; if (ent == null) return; //hInfo.Column==null 标示点了行头 if (hInfo.Column!=null && hInfo.Column.Caption == "图片") { var img=gridView1.GetFocusedValue() as Image; new frmPhotoDetail(img).ShowDialog(); return; } //双击其他标示修改 btnModify.PerformClick(); } };
4.窗体继承
4.1.如果显示设计时错误,需要把两个partial 类的父类都设置下
4.2.如果father是泛型类那么会一直显示设计时错误
4.3.父亲窗体中用From_Load 或重写了OnLoad时，里面不要写代码，如果要写需要加入if(!DesignMode){...}
4.4.在继承窗体上增加按钮,无法显示
5.样式与中文包
将zn-CN 复制到运行目录 执行下列代码
/// </summary> [STAThread] static void Main(params String[] args) { System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("zh-CN"); DevExpress.UserSkins.BonusSkins.Register(); DevExpress.Skins.SkinManager.EnableFormSkins(); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); if (args.Length >= 1 && args[0] == "test") { Application.Run(new Form1()); } else { Application.Run(new F.Studio.DevExpressUI.frmLogin()); } }
6.DateEdit显示时间
DateEdit如果开启Vista模式并显示日期+时间模式 问题，以前没有涉及过，借机看一下，记录如下：
设置为Vista显示模式（如下图）
参考 ：http://www.cnblogs.com/xiaofengfeng/archive/2011/09/07/2169691.html
设置以下属性
dateEdit1.Properties.VistaDisplayMode = DevExpress.Utils.DefaultBoolean.True;
dateEdit1.Properties.VistaEditTime = DevExpress.Utils.DefaultBoolean.True;
设置显示长日期模式（日期+时间）：
dateEdit1.Properties.DisplayFormat.FormatString="g"
dateEdit1.Properties.DisplayFormat.FormatType=DateTime
dateEdit1.Properties.EditFormat.FormatString="g"
dateEdit1.Properties.EditFormat.FormatType=DateTime
设置为Vista模式时，如果要显示日期+时间的长日期模式，还需要设置：
VistaTimeProperties.DisplayFormat
VistaTimeProperties.EditFormat
