C# Wpf允许按用户删除行，但禁止编辑DataGridTextColumn上的单元格
我有一个绑定列表的DataGrid 我有一个添加数据的方法，我想让用户用鼠标选择行并使用删除按钮来删除 ADD方法可以添加从Combobox中选择的特定数据，我不想让用户通过编辑单元格直接更改数据 我已尝试设置DataGrid.IsReadOnly=false和DataGridTextColumn.IsReadOnly=true 但是删除不起作用 要添加数据，我通过组合框选择数据，然后单击按钮执行方法：C# Wpf允许按用户删除行，但禁止编辑DataGridTextColumn上的单元格,c#,wpf,C#,Wpf,我有一个绑定列表的DataGrid 我有一个添加数据的方法，我想让用户用鼠标选择行并使用删除按钮来删除 ADD方法可以添加从Combobox中选择的特定数据，我不想让用户通过编辑单元格直接更改数据 我已尝试设置DataGrid.IsReadOnly=false和DataGridTextColumn.IsReadOnly=true 但是删除不起作用 要添加数据，我通过组合框选择数据，然后单击按钮执行方法：AddNewData 一切都很好 我怎么做 我的相关数据网格名为：x:Name=“Shifts
