Infragistics netadvantage UltraGrid (UltraWinGrid) 编程手记
UltraGrid 是Infragistics netadvanage 控件库中提供的一个Windows 网格控件，功能强大，完全可以取代VS 中提供的 GridView控件。但不知为何，国内介绍它的文章很少。这玩意功能是相当强大，但其属性设计原理和普通控件不太一样，属性极为复杂，没有手册几乎无法编码。在此我整理了一些资料，权当推广了。本是编程用的参考，文笔随意之处望见谅。kevin cheng 2008-08-20

一、UltraGrid 的基本概念
UltraGrid的属性设计和一般的控件颇为不同。理解其设计思想，有助于你从其浩瀚的属性中快速找到你所需要的东西。在此文中 WinGrid, UltraGrid, UltraWinGrid 是同一个东西。
WinGrid
是一个可展示层级数据的网格控件
数据源实现 IList 或 ITypedList 接口就可以展示（但不一定可以增删）
可展现具有层级关系的数据，如 customers - orders - order details
WinGrid 功能：
· 排序
· 过滤
· 统计
· 行列大小调整
· 冻结列和冻结行
· 列托拽调整位置
· 列互换位置
· 分割视图
· Outlook风格的BroupBy功能（用户可将列拖到分组栏中对数据进行分组）
· 卡片视图
· 数据行的自定义布局
· 单元格可使用多种编辑控件
· 导出到Excel
· 打印
· 其它Infragistics Presentation Layer Framework 的公共特性，如：Apperances, DrawFilters, CreationFilters
WinGrid 数据条带和层级数据
UltraGrid 可表现具有层级关系的数据
每个层级的数据用一个 band（数据条带）来描述
每个 band 具有若干的 column 和 row，类似 DataTable
层级间的关系用外键关联来描述
WinGrid 的外观样式方案
（1）使用 Appearance 对象控制控件的外观和样式
设置 WinGrid 控件的外观
· 并不直接设置其字体背景颜色等属性
· 而是创建或者选择现有的 Appearance 对象（类似Web的css class样式）
· 该 Appearance 对象拥有多种格式相关的属性，如对齐方式、字体、颜色、图像和alpha融合信息
该方式有以下好处：
· 缩减了代码的数量
· 便于控制统一的外观，只需要改 Appearance 对象就可以了
· 对于 Grid 这样具有众多子元素的控件，使用此方式设置外观可有效减少内存消耗
（2）其布局和外观是可持续化保存的
UltraGrid.DisplayLayout 属性（UltraGridLayout类）作为所有可持续化保存的特性和对象的容器
调用该对象的 Load(), Save(), LoadFromXml(), SaveAsXml() 函数可存取外观控制
由于大部分UltraGrid的设置都可以持续化，所以大部分的功能都是通过UltraGridLayout对象进行设置的
（3）样式是可从上级控件继承和重载的
若控件设置其 Appearance 为 Default，该控件将会继承其父控件的样式设置（而不是什么缺省值）
如缺省状态下，cell 使用row的背景色，而row使用band的背景色
Band 对象默认继承上级对象的样式，而使用Override 属性（UltraGridOverride 类）来设置其特殊属性
WinGrid 决定绘制一个对象的外观和行为时
· 先检查该对象的Override属性
· 若该属性内的值被明确修改（非Default），则使用该值
· 否则使用上级对象相应的值（Default）
大部分的属性即可以直接在WinGrid设置，也可以在Band设置，后者会覆盖前者
// 例：默认只能单行选择，而 orders band 允许选择多行
using Infragistics.Win.UltraWinGrid;
UltraGrid1.DisplayLayout.Override.SelectTypeRow = SelectType.Single;
UltraGrid1.DisplayLayout.Bands["Orders"].Override.SelectTypeRow = SelectType.Extended;
卡片视图（Card View）
每条记录用一张卡片来展示，类似表单视图
卡片视图的限制
只能展现最底层的band数据，无法再展示其子层的数据
无法增加新记录？
设置方法
grid.Band[0].CardView = true;
grid.Band[0].CardSettings..... 样式设置
分组视图（GroupBy View）
类似outlook 2007，可将列拖到分组栏中，让数据分组展示
操作方法：
grid.DisplayLayout.ViewStyleBand = ViewStyleBand.OutlookGroupBy;
二、 UltraGrid 设计器操作
UltraWinGrid Designer（UltraGrid设计器项目）
Basic Settings :
Data Schema : 设置绑定列的数据格式
Presets : 从预设中选择一个样式，有三种类型：（1）仅与外观相关;（2）仅与行为相关；（3）两者都有
Manage Presets : 预设管理和设置
Feature Picker : 配置功能。详见后
Appearance Browser : 定制的一些外观样式
Band and Column Settings : 要展示数据集和列设置
Band[0] - 'Band 0' :
Columns : 展示列设置：Data Schema中定义绑定列，非绑定列
Column Arrangement Overview : 列展示位置设置（类似报表设计器）
Column Arrangement Designer : 分两种：Row layout（可用于复杂表头设置）, Group and levels
Control Settings : 控件所有的属性设置。其实上面的所有设置都可以在这里找到，只是层次深不易找。详见下。
Feature Picker（UltraGrid功能设置）
AutoFit Style : 列自动适应宽度
CardView : 卡片视图
Column Moving : 列是否可拖动位置
Column Sizing : 列调整宽度的方式
Column Swapping : 是否允许列交换位置
Empty Rows : 是否展示空行，空行的样式
Filtering : 列过滤器
Fixed Headers : 冻结列
Fixed Rows : 冻结行
Header Click Sort Action : 标题列点击排序方式：单列排序 & 多列方式
IDataErrorInfo Support : 数据错误验证方式
Merged Cell : ？合并单元格
Outlook Group By : Outlook Group 风格（可由用户定制数据分组）
Row Selectors : 行选择符号（一个小箭头）
Row Siziing : 行调整高度的方式
Scrolling : 滚动条样式
Selection : 行列单元格选择方式
Summaries : 统计单元格
Updating : 是否允许数据行增删改
Control Setting（UltraGrid控件设置·特有属性）

排序：Picker/Filtring/Allow
分组：Picker/OutLook GroupBy/Active
编辑：Picker/Update
多行表头：Column Arrangement Designer/Add Group/Add Level/把相应的列拖到组下面，
隐藏列：Column Arrangement Designer/Show Hide
单列不可编辑：Band[0]/Column/cellactivation 设置成NoEdit
单击单元格选择状态：Band[0]/Column/CellClickAction
单元格编辑控件：Band[0]/Column/EditorControl
单元格合并：Band[0]/Column/MergedCell。。。
冻结列：Picker/Fixed Header
三、UltraGrid 外观控制

■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
动态转载样式文件
this.ultraGrid1.ApplyPresetFromXml(@"C:\Program Files\Common Files\Infragistics" +
@"\Presets\Win\UltraGridBase\Standard\FlatGreen.xml", true);
存取布局文件（可用这玩意设计报表，动态载入）
this.ultraGrid1.DisplayLayout.SaveAsXml("WinGridLayout.xml");
this.ultraGrid1.DisplayLayout.LoadFromXml(System.IO.Path.Combine(Application.StartupPath,
@"..\..\ExtraFiles\WinGridLayout.xml"));
使用Appearance（类似预定义的样式）
this.ultraGrid1.DisplayLayout.Appearances.Add("Highlighted" );
this.ultraGrid1.DisplayLayout.Appearances["Highlighted" ].BackColor = Color.Red;
this.ultraGrid1.DisplayLayout.Appearances["Highlighted" ].BackColor = Color.White;
或者直接给预设Appearance赋值
this.ultraGrid1.DisplayLayout.Override.ActiveRowAppearance.ForeColor = Color.White;
使用操作系统样式
this.ultraGrid1.UseOsThemes = DefaultableBoolean.True;
HotTrack
this.ultraGrid1.DisplayLayout.Override.HotTrackCellAppearance.BackColor = Color.Blue;
this.ultraGrid1.DisplayLayout.Override.HotTrackRowCellAppearance.BackColor =
Color.Yellow;
this.ultraGrid1.DisplayLayout.Override.HotTrackHeaderAppearance.BackColor =

this.ultraGrid1.DisplayLayout.Override.HotTrackRowAppearance.ForeColor =
Color.LightGreen;
this.ultraGrid1.DisplayLayout.Override.HotTrackRowSelectorAppearance.BackColor =

分割滚动视图
设置分割视图（创建SplitBar）
this.ultraGrid1.DisplayLayout.ColScrollRegions[0].Split(0);
this.ultraGrid1.DisplayLayout.RowScrollRegions[0].Split(200);

this.ultraGrid1.DisplayLayout.MaxColScrollRegions = 1;
this.ultraGrid1.DisplayLayout.MaxRowScrollRegions = 1;
修改Tab键功能
this.ultraGrid1.DisplayLayout.TabNavigation = TabNavigation.NextControl;
TabletPC Ink-Enable
将UltraInkProvider 组件拖到窗体上就可以了
编辑状态的输入框右侧会显示一个小笔按钮，点击后就会弹出手写输入框
若要在非TabletPC上使用该功能，需要安装TabletPC SDK

手工设置
在Properties-> DisplayLayout->ValueLists,添加ValueList
Properties-> DisplayLayout->bands->0-XXX->Columns->某个Column->ValueList等于新添加的
ValueList，同时设定Style是DropDown
还要再写个Event Handler，详细其他Style等等可以看这个Link:
http://devcenter.infragistics.com/Support/KnowledgeBaseArticle.Aspx?ArticleID=1708
代码设置
ValueList locValueList = this.ultraGrid.DisplayLayout.ValueLists.Add("Locs");

locValueList.ValueListItems.Add((int)(dr["ID"]), dr["Name"].ToString());
