很多程序可能都会有一个首页综合展示系统的相关信息，如汇总信息，图表统计、待办业务、提醒信息等内容，在Web上可能叫做Dashboard仪表板，或者首页页面，不管哪种叫法，都是综合展示一些信息，提供一些信息展示或者处理工作的入口，我们在Winform里面，有时候也需要这样的仪表板首页，这个使用DevExpress的控件组的话，可以使用WidgetView控件来实现。
1、DevExpress默认案例 DevExpress的Demo样例提供了一些WidgetView的样式，如下所示。
通过上面的案例，我们可以看到，利用WidgetView可以创建很丰富的汇总、报表、待办等相关内容，只要处理得当，可以为我们的Dashboard首页提供很丰富的综合内容展示。
2、WidgetView的使用介绍 WidgetView的使用，如果要较好掌握它的使用，需要了解DocumentManager、WidgetView、Document、StackGroup的概念是什么，以及它们之间的关系。
我们可以通过窗体的设计器来创建一个DocumentManager，其中DocumentManager里面包含一个WidgetView，用来做视图管理的；然后在设计模式上创建多个对应的Document，而Document是用来管理对应展示的内容的（如自定义用户控件），StackGroup等是用来管理Document布局展示的，除了StackLayout外，可以通过WidgetView的LayoutMode属性设置其他布局类型，如Table Layout, Flow Layout 以及 Free Layout等。如下是在设计模式下创建几个空白的Document以及使用的LayoutMode 为StackLayout来排版Document的排列方式。
如果需要在设计模式下维护WidgetView的一些内容，可以通过窗体下面的DocumentManager对象进行维护。
以上的Demo就是简单的创建几个空白的Document以及常规的StackLayout的方式排版，运行得到界面效果如下所示。
一般实际情况下，我们是在首页上综合展示各种报表内容、图表内容、待办信息等内容的，那么各个模块的内容，可以使用自定义用户控件来处理，然后综合展示即可，实际情况下，首先我们先创建用户控件界面，以及实现好各个内容的展示；然后我们可以在设计模式下指定不同Document下容纳的控件信息，也可通过动态创建的方式创建所需要的内容。
以下是我使用代码动态构建的WidgetView界面，通过动态创建DocumentManager、Document，以及加载各种自定义用户控件，组合成下面的界面效果。
用户自定义控件界面，我们在Controls里面放置各种不同内容的用户控件，如下界面方案中的项目文件界面所示。
动态创建WidgetView相关的内容比较简单，我这里把所有相关的代码一并贴出，方便了解。
复制代码 /// /// 动态构建的Widget View /// public partial class FrmWidget2 : DevExpress.XtraEditors.XtraForm { public FrmWidget2() { InitializeComponent(); }
private void FrmWidget2_Load(object sender, EventArgs e) { AddDocumentManager(); } WidgetView view; StackGroup group1, group2; void AddDocumentManager() { var docMananger = new DocumentManager(components); view = new WidgetView(); docMananger.View = view; docMananger.ContainerControl = this; view.AllowDocumentStateChangeAnimation = DevExpress.Utils.DefaultBoolean.True; group1 = new StackGroup(); group2 = new StackGroup(); group1.Length.UnitType = LengthUnitType.Star; group1.Length.UnitValue = 2; view.StackGroups.AddRange(new StackGroup[] { group1, group2 }); //添加文档

points.Add(new Point(i, j)); } } Random random = new Random(); foreach (Document document in view.Documents) { Point newLocation = points[random.Next(points.Count)]; document.RowIndex = newLocation.Y; document.ColumnIndex = newLocation.X; points.Remove(newLocation); } //添加 Document对象到group1不是必须的，因为所有新创建的文档都是默认放置到第一个StackGroup中. //group1.Items.AddRange(new Document[] { view.Documents[0] as Document,
