[CLOSED] Treegrid nodes

[AlbertoCe]

Hi,

I've some problems using the treegrid. If the grid load data using the model the nodes description are empty.



This is the controller action I use to render the view :

    public ActionResult Index()
    {
      NodeCollection nodes = new Ext.Net.NodeCollection();

      nodes.AddRange( new [] { new Node()
      {
        Text = "1",
        NodeID = "1",
        Leaf = true,
        AttributesObject = new
        {
          Code = "1Code",
          Description = "1Description",
          CreationDate = "1CreationDate",
          LastUpdateDate = "1LastUpdateDate"
        }
      },
      new Node()
      {
        Text = "2",
        NodeID = "2",
        Leaf = true, //c.Children.Any(),
        AttributesObject = new
        {
          Code = "2Code",
          Description = "2Description",
          CreationDate = "2CreationDate",
          LastUpdateDate = "2LastUpdateDate"
        }
      }      
      });

      return View(nodes);
    }

This is the view :

@model Ext.Net.NodeCollection
@(
 Html.X().Viewport()
  .Layout(LayoutType.Border)
  .Split(true)
  .Items(vpItems =>
  {
    vpItems.Add(
          Html.X().TreePanel()
            .Height(300)
            .Split(true)
            .AnimCollapse(true)
            .Collapsible(true)
            .Region(Region.Center)
            .UseArrows(true)
            .RootVisible(false)
            .Fields(
              Html.X().ModelField().Name("Description")
            )
            .ColumnModel(
              Html.X().TreeColumn().DataIndex("Description").Text("description")
            )
            .Root(Html.X().Node().NodeID("0").Text("description").Children(Model))
     );

 })
)

What should I change to make it work ?

Regards,
Alberto

Hello!

By default, all AttributesObject serializing to objects where name of fields starts with lowercase letter even.

@(
 Html.X().Viewport()
  .Layout(LayoutType.Border)
  .Split(true)
  .Items(vpItems => vpItems.Add(
    Html.X().TreePanel()
		.Height(300)
		.Split(true)
		.AnimCollapse(true)
		.Collapsible(true)
		.Region(Region.Center)
		.UseArrows(true)
		.RootVisible(false)
		.Fields(
            Html.X().ModelField().Name("description")
		)
		.ColumnModel(
            Html.X().TreeColumn().DataIndex("description").Text("description")
		)
        .Root(Html.X().Node().NodeID("0").Text("description").Children(Model))
  	)
  )
)

Hello,

Renaming the AttributesObject properties to lowercase works !

Thank you very much.

Alberto.

Hi,

Just to clarify: it is done to meet JavaScript naming convention, i.e. lowercase first letter of properties.
