visual-studio-2010 - 有关ItemsControl的XAML设计数据的问题

Question

我试图在我的MVVM项目中掌握VS2010(不是Blend)的设计数据。

我可以将其用于顶级VM属性，但是集合有问题。我使用DevForce进行数据建模，因此理想情况下，我的XAML应该如下所示:

<MaintainTruckViewModel 
    xmlns="clr-namespace:IDATT.Module.Assets.Views"
    xmlns:data="clr-namespace:IDATT.Model;assembly=IDATT.Model.SL">
    <MaintainTruckViewModel.CurrentItem>
        <data:ASTTruck
            TruckId="1000"
            ExternalTruckId="T1000"
            IsActive="True"
            VinNumber="1ZAXBV"
            Make="Volvo"
            Model="ABC"
            MakeYear="2010"
            PlateNumber="ABC 123"
            PlateIssueAdministrativeArea="MO"
            Height="110"
            AxlesCount="3">
            <data:ASTTruck.ASTInsurances>
                <data:ASTInsurance
                    InsuranceKey="1"
                    CompanyName="MainCo"
                    AgentCompanyName="Joes insurance"
                    CoverageAmount = "1000000"
                    DeductibleAmount = "1000"
                    InsuranceType = "General liability"
                    IsActive = "True"
                    PolicyNumber = "123ABC"
                    ExpireOn = "01-01-2012"
                    Note = "This insurance covers all stuff"/>
            </data:ASTTruck.ASTInsurances>
        </data:ASTTruck>
    </MaintainTruckViewModel.CurrentItem>
</MaintainTruckViewModel> 

我的xaml看起来像这样，我希望在设计 View 中看到ASTInsurance数据，但它不会显示

<ItemsControl 
                    Grid.Row="1"
                    ItemsSource="{Binding CurrentItem.ASTInsurances}">

我不知道如何制作各种列表以根据设计数据“工作”。有指针吗？我发现可以在列表中使用单独的d:DesignData并尝试创建此类XAML:

<Generic:List 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:Generic="clr-namespace:System.Collections.Generic;assembly=mscorlib"
    x:TypeArguments="data:ASTInsurance" 
    xmlns:data="clr-namespace:IDATT.Model;assembly=IDATT.Model.SL">
                <data:ASTInsurance
                    InsuranceKey="1"
                    CompanyName="Great West"
                    AgentCompanyName="Joes insurance"
                    CoverageAmount = "1000000"
                    DeductibleAmount = "1000"
                    InsuranceType = "General liability"
                    IsActive = "True"
                    PolicyNumber = "123ABC"
                    ExpireOn = "01-01-2012"
                    Note = "This insurance covers all stuff"/>

</Generic:List> 

现在XAML编辑器强调Generic.List并说 The type 'Generic:List' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built

尝试在XAML中使用System.Collections.Generic.List<T>的问题是(据我所知)XAML的Silverlight方言没有办法为通用类型参数指定值。您收到的错误是因为没有没有类型参数的System.Collections.Generic.List类型。

您可以做的一件事是创建List<T>的子类，该子类为type参数提供一个值，但不包含新成员或重写成员，例如:

public class ASTInsuranceList : List<ASTInsurance>
{
}

然后，您可以在XAML中使用 ASTInsuranceList对象来包含 ASTInsurance对象的列表。
