Question

我在父视图中有一个simpleButton，我希望将此按钮与子视图模型中的方法绑定。

_fluentApi.BindCommand(simpleButton , x => x.SaveMessage());

Answer 1

DevExpress MVVM Fluent API支持绑定到嵌套属性/命令：

// ViewModel
public class ParentViewModel {
    public ParentViewModel() {
        Child = ChildViewModel.Create();
    }
    public virtual ChildViewModel Child { 
        get;
        protected set;
    }
}
public class ChildViewModel{
    public static ChildViewModel Create() {
        return DevExpress.Mvvm.POCO.ViewModelSource.Create<ChildViewModel>();
    }
    public void Save(){
        // ...
    }
}

// View
var fluentApi = mvvmContext.OfType<ParentViewModel>()
fluentApi.BindCommand(simpleButton , x => x.Child.Save());

如何使用子视图模型方法创建父视图绑定命令
