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 设计器操作收藏

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
