description: DataGridEx WPF 表格控件的能力与用法，涵盖分页、行选择、序号、列显隐、自定义操作栏与分页栏、加载动画、排序和图片列。需要了解或配置 DataGridEx 时使用。

# DataGridEx
|
||||
|
||||
DataGridEx 继承 WPF DataGrid，提供以下能力。属性默认值和配置示例见 [references/usage.md](references/usage.md)。
|
||||
|
||||
## 行选择与序号
|
||||
|
||||
- 行头复选框与独立序号列，可分别显示或隐藏。
|
||||
- 表头支持全选、未选和部分选中的三态显示；全选范围是当前 ItemsSource/视图。
|
||||
- 点击行尾空白可选中对应行；支持行头点击切换选择、可选的右键选中和行菜单。
|
||||
- SelectedItems 支持绑定可增删集合，集合内增删与表格选择双向同步。使用 OneWay 绑定集合引用，无需属性 setter；不支持只读或固定大小集合。
|
||||
- 序号自动创建，按当前显示顺序和分页偏移计算，排序与行回收后更新。
|
||||
- 选中行背景与前景可配置。
|
||||
|
||||
## 分页
|
||||
|
||||
- 首页、上一页、下一页、末页、页大小选择、当前页和总记录数。
|
||||
- PageIndex、PageSize 支持绑定；翻页通过 PageChangedCommand 发出 DataGridPageRequest(PageIndex, PageSize)。
|
||||
- 换页或改变页大小清空选择；改变页大小回到第一页，总数减少时自动调整到有效页码。
|
||||
- 调用方提供当前页数据和总数；控件不请求数据，也不再次切分 ItemsSource。
|
||||
- ShowPagination 控制分页栏显隐。隐藏时仍保留分页状态；不分页时保持 PageIndex=1。
|
||||
|
||||
## 列与排序
|
||||
|
||||
- 支持原生 DataGrid 列类型和自定义模板列，列放在 DataGridEx.Columns 中。
|
||||
- 内置列设置面板，勾选后立即显示或隐藏列。
|
||||
- CanHideColumn=False 可将业务列设为固定显示；复选框与序号使用各自开关。
|
||||
- 列显示设置不持久化，没有额外的右侧冻结实现。
|
||||
- 支持表头排序，排序图标位于列右侧；默认仅对当前数据源排序。
|
||||
- 服务端全量排序由调用方处理 Sorting 事件并重新查询。
|
||||
|
||||
## 自定义内容
|
||||
|
||||
- ShowToolbar 控制操作栏显隐，ShowColumnSettings 控制列设置按钮。
|
||||
- ToolbarContent 自定义操作栏中间区域，保留选择提示和列设置按钮。
|
||||
- PaginationContent 替换整个分页栏；未设置或为 null 时使用默认分页栏。
|
||||
- 两个内容槽均继承调用方 DataContext，可放置按钮、统计文字和业务布局。
|
||||
|
||||
## 加载与空数据
|
||||
|
||||
- IsLoading 控制加载遮罩及不确定进度动画，LoadingText 配置提示文字。
|
||||
- 加载期间禁用表格、操作栏和分页栏，结束后恢复；不控制表格外部控件。
|
||||
- NoDataTips 配置空数据提示，IsActive 可抑制空数据提示，与 IsLoading 分开控制。
|
||||
- 加载状态由调用方设置，控件不推断请求开始、完成或失败。
|
||||
|
||||
## 图片列与虚拟化
|
||||
|
||||
- DataGridExImageColumn 支持图片地址绑定、占位图绑定及 ElementStyle。
|
||||
- 默认图片尺寸 58×58，Stretch=Uniform。
|
||||
- 可见单元格按需加载图片，行回收时取消旧请求，避免旧图片覆盖新行。
|
||||
- 支持图片缓存，以及拖动滚动条期间暂停图片加载、停止后恢复。
|
||||
- 启用行/列虚拟化和容器回收。
|
||||
|
||||
## 集合视图支持
|
||||
|
||||
ItemsSource 可绑定 ICollectionView。调用方可使用独立 ListCollectionView，通过 Filter 和 Refresh 实现当前页实时筛选并保留视图排序。
|
||||
|
||||
搜索输入框、匹配规则、后台查询、异步取消和跨页全部选择不属于控件内置能力。

# DataGridEx 调用与属性
|
||||
|
||||
## 常用接入
|
||||
|
||||
以下绑定属性由调用方 ViewModel 提供，controls 表示 DataGridEx 所在命名空间。
|
||||
|
||||
~~~xml
|
||||
<controls:DataGridEx x:Name="StoreGrid"
|
||||
IsReadOnly="True"
|
||||
ShowCheckBox="True" ShowRowNumber="True"
|
||||
ShowToolbar="True" ShowColumnSettings="True" ShowPagination="True"
|
||||
ItemsSource="{Binding CurrentItems, Mode=OneWay}"
|
||||
SelectedItems="{Binding SelectedStores, Mode=OneWay}"
|
||||
TotalItemCount="{Binding TotalCount, Mode=OneWay}"
|
||||
PageSize="50"
|
||||
PageChangedCommand="{Binding LoadPageCommand, Mode=OneWay}"
|
||||
IsLoading="{Binding LoadingStatus.IsLoading, Mode=OneWay}"
|
||||
LoadingText="{Binding LoadingStatus.Message, Mode=OneWay}">
|
||||
<controls:DataGridEx.ToolbarContent>
|
||||
<Button Content="批量操作" Command="{Binding BatchCommand, Mode=OneWay}"/>
|
||||
</controls:DataGridEx.ToolbarContent>
|
||||
<controls:DataGridEx.Columns>
|
||||
<DataGridTextColumn Header="店铺名称"
|
||||
Binding="{Binding Name, Mode=OneWay}"
|
||||
controls:DataGridEx.CanHideColumn="False"/>
|
||||
<DataGridTextColumn Header="店铺 ID"
|
||||
Binding="{Binding StoreId, Mode=OneWay}"/>
|
||||
</controls:DataGridEx.Columns>
|
||||
</controls:DataGridEx>
|
||||
~~~
|
||||
|
||||
首次数据由调用方装入，不依赖 PageChangedCommand 自动启动。默认不自动生成列；数据要使用正确的类型，日期/金额等通过绑定格式化展示。
|
||||
|
||||
## 常用属性
|
||||
|
||||
| 属性 | 当前默认值 / 约束 |
|
||||
| --- | --- |
|
||||
| ShowCheckBox / ShowRowNumber | false / false，分别显示选择行头与序号 |
|
||||
| ShowSelectAll | true；同时启用 ShowCheckBox 才显示表头全选 |
|
||||
| ShowToolbar / ShowColumnSettings / ShowPagination | true；列设置按钮位于操作栏 |
|
||||
| ToolbarContent | null；页面 DataContext 下的自定义批量操作内容 |
|
||||
| PaginationContent | null；自定义整个分页栏，null 恢复默认栏 |
|
||||
| PageIndex / PageSize | 1 / 50；均须大于 0，支持双向绑定 |
|
||||
| PageSizes | 20、50、100；自定义集合应包含当前 PageSize |
|
||||
| TotalItemCount | 0，不能为负数；应为后台查询总数而非当前页条数 |
|
||||
| PageChangedCommand | ICommand，参数 DataGridPageRequest |
|
||||
| IsLoading / LoadingText | false / 正在加载数据… |
|
||||
| SelectedItems | 原生选中集合；绑定时要求可增删集合 |
|
||||
| SelectedRowBackground / SelectedRowForeground | 浅梅紫 / 黑色 |
|
||||
| ToggleSelectionOnRowHeaderClick | true；点击行头切换选中 |
|
||||
| SelectRowOnRightClick | false；开启后右击未选中行会单选该行 |
|
||||
| RowContextMenu | null；行级菜单，行 Tag 可访问页面 DataContext |
|
||||
| NoDataTips / IsActive | 复用 DataGridHelper；IsActive=true 抑制空数据提示，不等同于 IsLoading |
|
||||
| PauseImageLoadingWhileDragging | true；拖动时暂停图片，停止滚动后延迟恢复 |
|
||||
| EnableImageCache | true |
|
||||
| CanHideColumn（附加属性） | true；对业务列设 false 可固定显示 |
|
||||
|
||||
只读状态：PageCount、PageSummary、TotalSummary、SelectionSummary、AreAllRowsSelected（三态）、IsSelectionModeActive、IsImageLoadingSuspended。不要尝试双向写入只读属性。
|
||||
|
||||
|
||||
|
||||
## 自定义分页栏
|
||||
|
||||
将下面属性元素放在命名为 StoreGrid 的 DataGridEx 内。内置路由命令包含 FirstPageCommand、PreviousPageCommand、NextPageCommand、LastPageCommand，边界由控件判定。
|
||||
|
||||
~~~xml
|
||||
<controls:DataGridEx.PaginationContent>
|
||||
<DockPanel>
|
||||
<StackPanel DockPanel.Dock="Right" Orientation="Horizontal">
|
||||
<Button Content="上一页"
|
||||
Command="{x:Static controls:DataGridEx.PreviousPageCommand}"
|
||||
CommandTarget="{Binding ElementName=StoreGrid, Mode=OneWay}"/>
|
||||
<TextBlock Margin="12,0" VerticalAlignment="Center"
|
||||
Text="{Binding PageSummary, ElementName=StoreGrid, Mode=OneWay}"/>
|
||||
<Button Content="下一页"
|
||||
Command="{x:Static controls:DataGridEx.NextPageCommand}"
|
||||
CommandTarget="{Binding ElementName=StoreGrid, Mode=OneWay}"/>
|
||||
</StackPanel>
|
||||
<TextBlock VerticalAlignment="Center"
|
||||
Text="{Binding TotalSummary, ElementName=StoreGrid, Mode=OneWay}"/>
|
||||
</DockPanel>
|
||||
</controls:DataGridEx.PaginationContent>
|
||||
~~~
|
||||
|
||||
PageIndex/PageSize 如需双向绑定，明确 Mode=TwoWay 和 UpdateSourceTrigger=PropertyChanged。隐藏分页栏不会停用分页状态或改变当前数据。
|
||||
|
||||
## 图片列
|
||||
|
||||
~~~xml
|
||||
<controls:DataGridExImageColumn Header="图片" Binding="{Binding ImageUrl, Mode=OneWay}"/>
|
||||
~~~
|
||||
|
||||
图片列使用 NetworkThumbnail，默认 58×58、Stretch=Uniform；可配置 ElementStyle 和 PlaceholderBinding。可见单元格按需加载，回收时取消旧请求，避免旧图片覆盖新行。拖动暂停和缓存由所属表格配置；它们不是表格整体加载动画的开关。
|
||||
|
||||
## 能力边界
|
||||
|
||||
列显示设置不持久化；没有额外的右侧冻结实现。控件支持 ICollectionView 数据源，但搜索输入与查询逻辑由调用方实现，不承担 HTTP 请求、数据库访问或跨页全部选择。
