Telerik Treeview DataBinding

Question

我有問題的數據綁定多個表中的一個兒童teir。所以說例如我有5張桌子。

contracts 
members 
phoneassessments 
homeassessments 
personalassessments 

每個評估表具有參考MEMBERID，我需要打印所有三種類型的分層評估的直屬會員，換句話說就是這個樣子。

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

我的代碼是...

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"); 
     })); 
    }) 
    ) 

所以我的問題是，下一步怎麼走？語法是什麼？

我不禁想起它會看起來像這樣。

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() 
     })); 
    }) 
    ) 

下面是我的控制器

public ActionResult TreeView() 
    { 
    var ctx = new SMTXContext(); 
    var Contracts = ctx.Contracts.ToList(); 
    return View(Contracts); 
    } 

，我在我看來使用作爲一個IEnumerable強類型從模型中的表相關的ActionResult。 （下面的線是在我看來，第一行

@model IEnumerable<SMTXEFMVCModel.Contract>

警告，這個「解決方案」沒有使用telerik treeview的數據綁定版本，但是對於任何想在樹視圖中將多個表格嵌套到單層的人來說，這似乎是一個可能的候選人。

@(

Html.Telerik().TreeView() 
    .Name("SeniorMetrix") 
    .Items(member => { 
     foreach (var member1 in members) 
      member.Add() 
      .Text(member1.FirstName.ToString()) 
      .SpriteCssClasses("icon-members") 
      .Items(occurance => 
      { 
      //lets print In-Home Assessments first 
      foreach (var inhomeassessment1 in inHomeAssessments) 
       if (inhomeassessment1.MemberID == member1.MemberID) 
       { 
       occurance.Add() 
       .Text("In-Home Assessment #" + inhomeassessment1.InHomeAssessmentID.ToString()) 
       .SpriteCssClasses("icon-assessments"); 
       } 
      //now we print Telephonic Assessments 
      foreach (var telephonicassessment1 in telephonicAssessments) 
       if (telephonicassessment1.MemberID == member1.MemberID) 
       { 
       occurance.Add() 
       .Text("Telephonic Assessment #" + telephonicassessment1.TelephonicAssessmentID.ToString()) 
       .SpriteCssClasses("icon-phone"); 
       } 
      //finally, let's print Episodes 
      foreach (var episode1 in episodes) 
       if (episode1.MemberID == member1.MemberID) 
       { 
       occurance.Add() 
       .Text("Episode #" + episode1.EpisodeID.ToString()) 
       .SpriteCssClasses("icon-episodes") 
       .Items(assessment => 
        { 
        foreach (var assessment1 in Episodes) 
         if (assessment1.EpisodeID == episode1.EpisodeID) 
         { 
         if (assessment1.AssessmentTypeID == 1) 
         { 
          assessment.Add() 
         .Text("Admission Assessment #" + afeassessment1.AssessmentID.ToString()) 
         .SpriteCssClasses("icon-assessment"); 
         } 
         if (assessment1.AssessmentTypeID == 2) 
         { 
          assessment.Add() 
         .Text("Interum Assessment #" + assessment1.AssessmentID.ToString()) 
         .SpriteCssClasses("icon-assessment"); 
         } 
         if (assessment1.AssessmentTypeID == 3) 
         { 
          assessment.Add() 
         .Text("Discharge Assessment #" + assessment1.AssessmentID.ToString()) 
         .SpriteCssClasses("icon-assessment"); 
         } 
         if (assessment1.AssessmentTypeID == 4) 
         { 
          assessment.Add() 
         .Text("Followup Assessment #" + assessment1.AssessmentID.ToString()) 
         .SpriteCssClasses("icon-assessment"); 
         } 
         } 
       }); 
      }}); 
    }))

前提是你的類有彼此的正確關係，因爲它應該是簡單：

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; 
          ... 
         })); 
      }) 

我說應該是因爲Telerik控件的確切功能往往會在您推入正常邊界時變得「模糊」，尤其是像MVC控件這樣的新界面。顯示確切的文檔如何做你想做的事情的例子。我已經使用上面的代碼得到了這個工作，但是我的模型和類可能不會像您一樣設置。
