C# Telerik Treeview数据绑定

我在一个孩子区绑定多个表时遇到问题。比如说我有5张桌子

contracts
members
phoneassessments
homeassessments
personalassessments

每个评估表都有引用MemberID，我需要在Members下的层中直接打印所有三种类型的评估，换句话说，如下所示

Contract 1
    Member 1
        Home Assessment 1
        Home Assessment 2
        Phone Assessment 1
        Personal Assessment 1
        etc
    Member 2

Html.Telerik().TreeView()
   .Name("TreeName")
   .BindTo(Model, mappings =>
     {
       mappings.For<SMTXEFMVCModel.Contract>(binding => binding
         .ItemDataBound((item, contract) =>
           {
             item.Text = contract.Description;
             item.SpriteCssClasses = ("icon-contracts");
           })
           .Children(Contract => Contract.Members));
       mappings.For<SMTXEFMVCModel.Member>(binding => binding
         .ItemDataBound((item, member) =>
           {
             item.Text = member.FirstName + " " + member.LastName;
             item.SpriteCssClasses = ("icon-members");
           {)
           .Children(Members => Members.Assessments));
        mappings.For<(SMTXEFMVCModel.HomeAssessments,SMTXEFMVCModel.PhoneAssessments,
                      SMTXEFMVCModel.PersonalAssessments)>(binding => binding
         .ItemDataBound((item, assessments) =>
           {
             item.Text = HomeAssessments.AssessmentID.ToString()
             item.Text = PhoneAssessments.AssessmentID.ToString()
             item.Text = PersonalAssessments.AssessmentID.ToString()
        }));
     })
    )

我的密码是

Html.Telerik().TreeView()
   .Name("TreeName")
   .BindTo(Model, mappings =>
     {
       mappings.For<SMTXEFMVCModel.Contract>(binding => binding
         .ItemDataBound((item, contract) =>
           {
             item.Text = contract.Description;
             item.SpriteCssClasses = ("icon-contracts");
           })
           .Children(Contract => Contract.Members));
       mappings.For<SMTXEFMVCModel.Member>(binding => binding
         .ItemDataBound((item, member) =>
           {
             item.Text = member.FirstName + " " + member.LastName;
             item.SpriteCssClasses = ("icon-members");
        }));
     })
    )

在我的视图中，我使用它作为IEnumerable来从模型中强类型表。（在我看来，下面这一行是第一行

@model IEnumerable<SMTXEFMVCModel.Contract>

@model IEnumerable

如果您的类彼此之间有正确的关系，它应该简单到：

Html.Telerik().TreeView() 
            .Name("TreeName") 
            .BindTo(Model, mappings =>  
            { 
                mappings.For<SMTXEFMVCModel.Contract>(binding => binding 
                        .ItemDataBound((item, contract) => 
                        { 
                            item.Text = contract.Description;
                            item.SpriteCssClasses = ("icon-contracts");
                        }) 
                        .Children(contract => contract.Members)); 
                mappings.For<SMTXEFMVCModel.Member>(binding => binding 
                        .ItemDataBound((item, member) => 
                        { 
                            item.Text = member.FirstName + " " + member.LastName;
                            item.SpriteCssClasses = ("icon-members");
                        }) 
                        .Children(member => member.Assessments)); 
                mappings.For<MSMTXEFMVCModel.Assessments>(binding => binding 
                        .ItemDataBound((item, assessments) => 
                        { 
                            item.Text = assessments.AssessmentType;
                            ...
                        }));
            }) 

Html.Telerik（）.TreeView（）
.名称（“TreeName”）
.BindTo（模型，映射=>
{ 
mappings.For（binding=>binding
.ItemDataBound（（项目，合同）=>
{ 
item.Text=合同描述；
item.spritecsclasses=（“图标合同”）；
}) 
.儿童（合同=>合同成员）；
mappings.For（binding=>binding
.ItemDataBound（（项目，成员）=>
{ 
item.Text=member.FirstName+“”+member.LastName；
item.spritecsclass=（“图标成员”）；
}) 
.儿童（成员=>成员评估）；
mappings.For（binding=>binding
.ItemDataBound（（项目，评估）=>
{ 
item.Text=assessments.AssessmentType；
...
}));
}) 

我说这应该是因为Telerik控件的确切功能在你推进正常边界时往往变得“模糊”，特别是像MVC控件这样的新控件

我相信您已经看过了这些示例，但是文档中没有显示如何执行您尝试执行的操作的确切示例。我已经使用上述代码实现了这一点，但是我的模型和类的设置可能与您的不同。

警告，这是“解决方案”没有使用telerik treeview的数据绑定版本，但是对于任何试图将多个表嵌套到treeview的一个层中的人来说，它似乎是一个很可能的候选

这将列出各个成员的所有评估（如果我将所有评估存储在一个表中，这将是非常好的，但我正在查看3个不同的评估表（电话、电话、个人）进入这一层。我需要所有三个层的映射。我将编辑我的帖子，以显示我觉得它可能会是什么样子，尽管我无法让它工作。如果你的模型为成员正确设置，它似乎可以工作。评估。你能发布更多关于模型结构的信息吗？你到底想知道什么？我对一些术语相当陌生。您需要表名、关系（1到多），从实体框架中的模型创建的类名？是的，EF信息。每个表都有自己的类吗？它有自己的上下文吗？实现更新的代码时会显示什么？每个表都有自己的类。每个表都没有自己的上下文（这将在控制器中定义？）目前在控制器中，我传递了treeview（契约）中使用的第一个上下文，这仍然让我可以深入到我想要的地方。我将使用treeview的控制器操作结果更新帖子。更新的代码不会调试，多重for映射的语法非常错误。：（你真是太狡猾了，对条件句的思考很好。很高兴你找到了让它对你有用的方法。
