Telerik Treeview MVC

我正在尝试使用c#在MVC中使用Telerik Treeview。我有3个模型,只需要2个层次(根和子)的节点。我需要根节点是第一模型,子节点是第三模型。两者都由第二模型连接。

下面是我写的代码:
@using Hant.Material.ValueObject.Domain
@using Hant.Material.Web.Models
@model IEnumerable<DescriptivePatternModel>
@{
    Html.Telerik().TreeView()
        .Name("treeView")
        .ExpandAll(true)
        .BindTo(Model, mapping => mapping
            .For<DescriptivePatternModel>(binding => binding
                .Children(descriptivePattern => descriptivePattern.Items)
                .ItemDataBound((i, descriptivePattern) =>
                {
                    i.Text = descriptivePattern.Name;
                    i.Value = descriptivePattern.Id.ToString();
                })
            )
            .For<ItemModel>(binding => binding
                .ItemDataBound((i, item) =>
                {
                    i.Text = item.VersionDate.ToString();
                    i.Value = item.Id.ToString();
                })
            )            
            ).Render();
}

在这段代码中,我只能访问Second Model

我也有同样的问题。你需要一些东西从控制器返回json结果。在你的action方法中创建一个TreeViewItem,绑定它并作为jsonresult返回。注意treeview项是如何返回的。您可以根据具体情况返回treeviewitem。

,

 public JsonResult RefreshGroups(Group currentGroup, int rootUserGroupId)
    {
        parentIds = new List<int> { rootUserGroupId };
        var groupsTree = new List<Group> { GetGroupHierarchy(currentGroup, rootUserGroupId) };

        var treeViewItem = new TreeViewItem();
        treeViewItem.BindTo(groupsTree, mappings =>
                                            {
                                                mappings.For<Group>(binding => binding
                                                .ItemDataBound((item, group) =>
                                                                    {
                                                                        item.Text = group.GroupName;
                                                                        item.Value = group.GroupID.ToString();
                                                                        item.LoadOnDemand = true;
                                                                    })
                                                .Children(group => group.SubGroups));
                                            });
        return new JsonResult
                   {
                       Data = new
                                  {
                                      ExpandedNodes = parentIds,
                                      Nodes = treeViewItem.Items
                                  }
                   };
    }

也许你可以试试这个:

Children(descriptivePattern => descriptivePattern.Items.First().ThirdModelCollection)
