Defining TreeView DataSource as XML

[OnaBai]

Today I've noticed that when using an XML DataSource in a TreeView, KendoUI complains about level method not being defined.

As far as I've seen this method is defined in Data Model but seems that for XML DataSources the code follow a different path and level is not defined.

Given the XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
    <doc>
        <nome>fabio</nome>
    </doc>
    <doc>
        <nome>mauro</nome>
    </doc>
</root>

And the following JavaScript code for defining the grid and the datasource:

var ds = new kendo.data.HierarchicalDataSource({
    transport: {
        read: {
            url     : "kendoTWData.xml",
            dataType: "xml"
        }
    },
    schema   : {
        type : 'xml',
        data : '/root/doc',
        model: {
            fields: {
                nome: "nome/text()"
            }
        }
    }
});

$("#treeview").kendoTreeView({
    dataSource   : ds,
    dataTextField: "nome"
});

 It complains about level not being defined.

If I add into the model a level function returning any number then it works.

model: {
    fields: {
        nome: "nome/text()"
    },
    level : function () {
        return 0;
    }
}

Is this a bug or XML datasources are not supported in Kendo UI TreeView widgets?

Hello Emiliano,

The HierarchicalDataSource, and the TreeView widget that uses it, do not support binding to XML at this time. Feel free to log a feature request on uservoice.

All the best,
