WPF Datagrid “Select All” button - “Unselect All” too?

阅读更多关于 WPF Datagrid “Select All” button - “Unselect All” too?

问题 I would like to know if it would be possible to add functionality to the 'Select All' button in the top left of a datagrid so that it also unselects all rows? I have a method attached to a button which does this, but it would be great if I could fire this method from the Select All button, to keep functionality in the same part of the view. Can this 'Select All' button have code added to it, and if so, how would one get to the button? I haven't been able to find any examples or suggestions.

目录介绍先决条件使用代码转换器数据网格绑定按钮绑定结论下载源代码和项目文件-397.4 KB 介绍这个小应用程序演示了一种基于 DataGrid 单元格内容动态修改单元格样式的方法。动态样式的一个示例：如果单元格中的值变为负数，则可能需要将单元格的背景色更改为红色。尤其强调了 Model-View-ViewModel （ MVVM ）模式来演示此样式。我提供完整的 Visual Studio 源代码和其他项目文件。可以从本文头部下载该项目的工作示例。在应用程序中，每当用户单击 [CHANGE VALUES] 时， DataGrid 中的单元格就会填充 1 到 9 的新随机整数。单元格的背景颜色会根据单元格的新内容而变化。先决条件该解决方案是使用 Visual Studio 2019 社区版 16.3.9 版和 .NET 4.7.2 构建的。它还需要 Expression.Blend.Sdk 版本 1.0.2 ，但是此 SDK 与项目文件打包在一起。还假定读者对 C ＃ WPF 项目和 MVVM 模式有基本的了解。使用代码当您生成并运行代码时，将出现以下窗口：注意：单元格中的整数是由随机生成器生成的，每次运行代码时以及每次单击 [CHANGE VALUES] 按钮时都会不同。我意识到颜色有点扎眼，但目的是清楚地显示当 DataGrid

WPF DataGrid标题Header Binding失效

前言：因业务需要对 WPF 中的 DataGrid 控件中的行数进行统计，同时把统计的行数显示在列标题上。如果我们用常规的 Binding 手段更新DataGridTextColunm 的 Header 的话是不会生效的，因为WPF中视觉树中没有DataGridTextColumn 元素来映射它（DataGridTextColumn不是控件，因此它没有父控件）。错误示范： <DataGridTextColumn Binding="{Binding Test}" Header="{Binding ColName}"/> 因为视觉树的机制，我们只需要把列标题视为一个控件即可（注：Header属性会失效，需要初始化Binding的字段）： <DataGridTextColumn Binding="{Binding Test}"Header="列名"> <DataGridTextColumn.HeaderTemplate> <DataTemplate> <TextBlock Text="{Binding DataContext.ColName,UpdateSourceTrigger=PropertyChanged,Mode=TwoWay, RelativeSource={RelativeSource AncestorType=DataGrid}}"
