我试图整理一个真正简单的MVC DataBind示例。我在MVC3中比较Telerik与DevExpress Grid。其中一个目标是在DDD方法中使用Enitiy Framework和Autofac,这使得它与我们的项目当前和将来使用新控件的方式非常接近。创造最公平的测试。
Telerik是一件轻而易举的事,我不得不想象DevExpress同样易于使用,但我仍然遇到了一个我无法解决的例外情况。
{"此解析操作已经结束。注册时 使用lambdas的组件,IComponentContext' c'参数 lambda无法存储。相反,要么解析IComponentContext 再次来自'或解析Func<>基于工厂创建后续 来自。"}
的组件
我对它进行了一些研究,我已经调用了c.Resolve(),许多人说这是修复,所以我不确定为什么我一直遇到这个问题,Telerik没有遇到同样的问题建立。
我很确定它不是DevExpress问题,而且我认为我在使用autofac时遇到了错误。然而,如果这是DevExpress和autofac协同工作的方式,那么这将是一个问题,因为我们非常依赖autofac而且我真的很想做一些事情,以便在Telerik开箱即用的时候能够使用它。
有人可以告诉我,如果我做错了,并指出我正确的方向,或告诉我这是否是一个DevExpress和autofac问题,而不是可以轻松修复并需要解决方法?< /强>

Telerik的其他所有内容都是相同的,所以我将发布Telerik的工作视图没问题。 Telerik查看
@model IEnumerable<Domain.Entities.FactResellerSale>
@{
ViewBag.Title = "GridView";
}
<h2>GridView</h2>
@(Html.Telerik().Grid(Model)
.Name("Grid")
.PrefixUrlParameters(false)
.Columns(columns =>
{
columns.Bound(o => o.ProductKey).Width(50);
columns.Bound(o => o.DimDate.FullDateAlternateKey);
columns.Bound(o => o.DimReseller.ResellerName);
columns.Bound(o => o.DimEmployee.FullName);
columns.Bound(o => o.SalesOrderNumber);
})

你的问题在这里:
builder.Register(c => new PropertyInjectedLazyLoadedObjectContextFactory(c.IsRegistered, c.Resolve))
.As<IObjectContextFactory>()
.InstancePerLifetimeScope();
为了向c(IComponentContext)注入句柄,您必须先解决它。像这样更改你的代码:
builder.Register(c => {
var context = c.Resolve<IComponentContext>();
return new PropertyInjectedLazyLoadedObjectContextFactory(context.IsRegistered, context.Resolve))
}
.As<IObjectContextFactory>()
.InstancePerLifetimeScope();
