WPF + DevExpress学习02 甘特图学习
学习成果
首先开发过程中 出现多次命名空间不对的异常
解决方案 1 清理解决方案 2 重新生成
WPF 绑定 DataContext 的方式
第一种
xmlns:local="clr-namespace:NhxProjectSystem.Modules.ViewModels"
DataContext="{dxmvvm:ViewModelSource Type={x:Type local:StartupBusinessPlanViewModel}}"
第二种
<UserControl.DataContext>
<local:StartupBusinessPlanViewModel ></local:StartupBusinessPlanViewModel>
</UserControl.DataContext>
部分代码 参考了官方Demo
