Windows phone 8 如何为caliburn.micro添加自定义约定?_Windows Phone 8_Naming Conventions_Caliburn.micro - Fatal编程技术网

Windows phone 8 如何为caliburn.micro添加自定义约定?

Windows phone 8 如何为caliburn.micro添加自定义约定?,windows-phone-8,naming-conventions,caliburn.micro,Windows Phone 8,Naming Conventions,Caliburn.micro,在我的项目中,我需要将ui元素的可见性绑定到bool属性,正如您所知,caliburn.micro具有约定“CanName”,所以我想添加我自己的自定义约定。 然后我发现这个[Visibility Autobinding with naming convention]我在我的项目中添加了这个代码,但它不起作用,而且约定“CanName”也不起作用 ConventionManager.AddElementConvention<FrameworkElement>(Control.Visi

在我的项目中,我需要将ui元素的可见性绑定到bool属性,正如您所知,caliburn.micro具有约定“CanName”,所以我想添加我自己的自定义约定。 然后我发现这个[Visibility Autobinding with naming convention]我在我的项目中添加了这个代码,但它不起作用,而且约定“CanName”也不起作用

ConventionManager.AddElementConvention<FrameworkElement>(Control.VisibilityProperty, "Visibility", "IsVisible");
            var baseBindProperties = ViewModelBinder.BindProperties;
            ViewModelBinder.BindProperties = (frameWorkElements, viewModel) =>
            {
                BindVisiblityProperties(frameWorkElements, viewModel);
                return baseBindProperties(frameWorkElements, viewModel);
            };


static void BindVisiblityProperties(IEnumerable<FrameworkElement> items, Type viewModel)
        {
            foreach (FrameworkElement element in items)
            {
                string PropertyName = element.Name + "IsVisible";
                var property = viewModel.GetPropertyCaseInsensitive(PropertyName);
                if (property != null)
                {
                    var convention = ConventionManager.GetElementConvention(typeof(FrameworkElement));
                    ConventionManager.SetBindingWithoutBindingOverwrite(viewModel, PropertyName, property,
                        element, convention, convention.GetBindableProperty(element));
                }
            }
        }
ConventionManager.AddElementConvention(Control.VisibilityProperty,“可见性”、“IsVisible”);
var baseBindProperties=ViewModelBinder.BindProperties;
ViewModelBinder.BindProperties=(框架元素,viewModel)=>
{
BindVisiblityProperty(框架元素、视图模型);
返回baseBindProperties(frameWorkElements、viewModel);
};
静态void bindVisiblityProperty(IEnumerable项,类型viewModel)
{
foreach(项目中的框架元素)
{
字符串PropertyName=element.Name+“IsVisible”;
var property=viewModel.getPropertyCaseSensitive(PropertyName);
if(属性!=null)
{
var convention=ConventionManager.GetElementConvention(typeof(FrameworkElement));
ConventionManager.SetBindingWithoutBindingOverwrite(viewModel、PropertyName、property、,
元素,约定,约定.GetBindableProperty(元素));
}
}
}

有人知道这段代码有什么问题吗?

我在我的项目中使用了这个约定,没有任何问题。下面是一个演练:

AppBootstrapper.cs
中,在其他给定约定中包括元素约定

private static void AddCustomConventions()
{
ConventionManager.AddElementConvention(Control.VisibilityProperty,“可见性”、“IsVisible”);
var baseBindProperties=ViewModelBinder.BindProperties;
ViewModelBinder.BindProperties=(框架元素,viewModel)=>
{
BindVisiblityProperty(框架元素、视图模型);
返回baseBindProperties(frameWorkElements、viewModel);
};
}
和您的助手方法:

private static void bindVisiblityProperty(IEnumerable items,类型viewModel)
{
foreach(项目中的框架元素)
{
字符串PropertyName=element.Name+“IsVisible”;
var property=viewModel.getPropertyCaseSensitive(PropertyName);
if(属性!=null)
{
var convention=ConventionManager.GetElementConvention(typeof(FrameworkElement));
ConventionManager.SetBindingWithoutBindingOverwrite(
viewModel,PropertyName,property,element,convention,convention.GetBindableProperty(element));
}
}
}
PageView.xaml中放置控件并提供
x:Name


开始
停止
福
酒吧
PageViewModel.cs
中放置一个
public属性
,类型为
bool
,后缀为IsVisible

public bool FooIsVisible{get{return true;}}
公共bool BarIsVisible{get{return false;}

你的使用环境如何?wp8?我不理解你的后续问题?你能把它放在给定问题/答案的上下文中吗?这似乎不适用于当前版本。如果我在此方法中设置断点并打开页面,则
frameWorkElements
仅包含顶级控件,如
网格
堆栈面板
。是否需要递归循环?
