TreeView is not rendering

[Miroslav Mrazik]

Hi,

I'm trying to create a view with TreeView bound to local datasource. I do it according to this tutorial from your documentation except that I do not use those styles and splitter and of course I looked at demos but that didn't help as well. The result is still an empty page. I attached my sample project. Can you please tell me what am I still missing?

Hi Miroslav,

Thanks for using Syncfusion products.

We have analyzed the sample that you have attached. It is found that, members of the <List> “TreeViewItem” are not properly mapped to the “TreeViewFields”. In the “Text” field, it is mapped as “Text” instead of “name”. This is the root cause for the reported issue (“Tree view not rendering”). So, please use the Tree view fields as shown below,

 

@Html.EJ().TreeView("MyTreeView").TreeViewFields(s => s.Datasource((IEnumerable<TreeViewItem>)ViewBag.TreeViewDS).Id("Id").ParentId("ParentId").Text("Name"))

 

 

Also, it is found that “ej.theme.min.css” and “ej.widgets.core.min.css” files are not included in your project. “ej.widgets.all.min.css” has reference to the above mentioned files. So, it is necessary to include these two files. We have made these changes in your project and attached the same in the following location.

Also, you can refer the following online documentation link to get start with our ASP.NET MVC components.
