No records to display even when I can see data in Network Monitor

[John]

I'm using the MVC extensions to setup my Tree List

@(Html.Kendo().TreeList<SiteMapTreeModel>()
      .Name("treelist")
      .Columns(columns =>
          {
              columns.Add().Field(c => c.Title).Title("Title").Width(250);
              columns.Add().Field(c => c.Url).Title("URL");
          })
      .DataSource(dataSource => dataSource
          .Read(read => read.Action("SiteMapTree", "HomeAjax").Data("getServiceAndLocale"))
          .Model(model =>
              {
                  model.Id(m => m.Id);
                  model.ParentId(m => m.ParentId);
                  model.Field(m => m.Title);
                  model.Field(m => m.Url);
              })
      )
      .AutoBind(false)
      .Selectable(true)
      .Deferred()
      .Height(540))

... and using Chrome Dev Tools > Network, I see the following data in the AJAX method SiteMapTree, but the Tree List says "No records to display":

{"Data":[{"Id":1602,"ParentId":1000,"Title":"Dashboard","Url":"~/Dashboard/Start","hasChildren":true},{"Id":22,"ParentId":1000,"Title":"Rules","Url":"~/Rules/Start","hasChildren":true},{"Id":1,"ParentId":1000,"Title":"Administration","Url":"~/Admin/Start","hasChildren":true}],"AggregateResults":{},"Errors":null}

... and I am using ToTreeDataSourceResult() in the AJAX method to format the data (and ParentId of 1000 is the root of the tree).

What am I doing incorrectly?

FYI: I have set the AutoBind of the TreeList to false because I am calling dataSource.read(); when a dropdownlist item is selected. The Tree List has no context until the dropdown is selected.

Thanks,

Hello John,

TreeListDtaSource will use parent key field default value to determine whether it is a root node. By default it expects to find ParentId with value of null for root nodes.

In your data however there aren't such nodes. That said you can add 100 as default value for the parent id field.

.Model(model =>
{
 model.Id(m => m.Id);
 model.ParentId(m => m.ParentId).DefaultValue(100);
 model.Field(m => m.Title);               
})

This is very interesting Nikolay, because I _do_ have null values for my parentId fields and still get the same error as the previous dev was getting while using the MVC treelist control.  I am at wit's end here.  The strange thing is that I can get the javascript version of this to work fine (my data comes back great).  I don't think my set up / config is any different between them.

Here's the JSON being returned by my controller:

I was not using the ToTreeDataSourceResult() extension in my controller method...I solved the immediate issue.

Hello John,

Seems that you've managed to resolve the issue which you had. Thus I will close this thread.

Hi Telerik,

I'm using Html.Kendo().TreeList, check tab Network on chrome I saw call API 200 and return data, but list alert no records to display

My code

@(Html.Kendo().TreeList<EmployeeDirectoryModel>()
            .Name("treelist")
            .Columns(columns =>
            {
                columns.Add().Field(e => e.FirstName).Title("First Name").Width(220);
                columns.Add().Field(e => e.LastName).Title("Last Name").Width(200);
            })
            .DataSource(dataSource => dataSource
                .Read(r => r.Url("/Index?handler=Read").Data("forgeryToken"))
                .Update(u => u.Url("/Index?handler=Update").Data("forgeryToken"))
                .Create(c => c.Url("/Index?handler=Create").Data("forgeryToken"))
                .Destroy(d => d.Url("/Index?handler=Destroy").Data("forgeryToken"))
                .Model(m =>
                {
                    m.Id(f => f.EmployeeId);
                    m.ParentId(f => f.ReportsTo).DefaultValue(100);
                    m.Field(f => f.FirstName);
                    m.Field(f => f.LastName);
                })
            )
            .Height(540)
        )

public JsonResult OnPostRead([DataSourceRequest] DataSourceRequest request)
    {
        var result = employees.ToTreeDataSourceResult(request,
                e => e.EmployeeId,
                e => e.ReportsTo,
                e => e
            );

        return new JsonResult(result);
    }
