填充KendoUi树视图与RavenDB文件

本文介绍了填充KendoUi树视图与RavenDB文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用MVC4和C＃。我有一个KendoUI树形，我想从RavenDB数据来填充它。

I am using MVC4 and C#. I have a KendoUI Treeview and I'd like to populate it with data from RavenDB.

在演示他们使用这样的：

In the demo they use this:

public JsonResult Employees(int? id) { var dataContext = new NorthwindDataContext(); var employees = from e in dataContext.Employees where (id.HasValue ? e.ReportsTo == id : e.ReportsTo == null) select new { id = e.EmployeeID, Name = e.FirstName + " " + e.LastName, hasChildren = e.Employees.Any() }; return Json(employees, JsonRequestBehavior.AllowGet); }

注意参数ID - 这是一个int。在RavenDb文件的ID都是字符串如。 myDco / 231 ...

Notice the argument "id" - it's an int. In RavenDb document ID's are strings eg. myDco/231...

想象一下，这是一个标准的文件：

Imagine this is a standard document:

{ "CreationDate": "12/12/2012 8:07:59 PM", "Name": "jkljklk", "Type": "kljkljkljkljkl", "Description": "ljkljklj", "CreatedByUser": "ljklklkljklj", "Deleted": false, "Status": "NEW", "Parent": "product/546" }

我将如何填充树视图？

How would I populate the treeview?

推荐答案

我想通了这一点。

我改变了我的RavenDB文件包含所有的儿童名单：

I changed my RavenDB Document to include a list of all its children:

{ "CreationDate": "12/12/2012 9:33:34 PM", "Name": "hohoho", "Type": "hohohoh", "Description": "hohohoh", "CreatedByUser": "hohohoh", "Deleted": false, "Status": "NEW", "Parent": "ohohohoh", "Children": [ "item/1", "item/2", "item/3" ] }

我再回到我的项目清单通过控制器的视图，然后通过他们迭代，所有的孩子追加到他们的正确的父节点：

I then returned a list of my items to the View via the controller and then iterated through them, appending all the children to their correct parent nodes:

@(Html.Kendo().TreeView().Name("TreeView").DragAndDrop(true) .Items(treeview => { foreach (var myItem in Model) { var myItemName = myItem.Name; var children = myItem.Children; treeview.Add().Text(myItemName ).Expanded(false).Items(branch => { if (children != null) { foreach (var child in children) { branch.Add().Text(child); } } }); } } ))

无论如何，感谢您的答复：）

Anyway, thanks for the responses :)
