Question

我有这个漂亮的小窗户。

我希望此DataGrid关闭我的大小调整和重新排序功能，我希望无法编辑单元格。但是，这是行不通的。.我希望当我单击行时仍能选择并突出显示行。由于某些原因，这不起作用...

MVCE：即使在该行上选择行也不起作用

Answer 1

这是错误的地方，错误是我在<TabControl SelectionChanged="TabControl_SelectionChanged"> SelectionChanged中所做的，正在设置数据网格内容。事实证明，每当您在选项卡中选择控件时，该事件都会冒泡至TabControl，因此该行不会被选中。

WPF DataGrid在TabItem中无法选择行
