TreeView Nodes

[Stid]

Does the Treeview Node have an ID field -  if not it would be nice to use for a DB Primary Key (I have looked maybe missed it!)

but I think the whole set of controls are very clean and sleek - great work

Hi Stid,

The TreeView has not an explicit ID field, but you can attach arbitrary data through the data- attributes.

<ul id="treeview">
    <li data-expanded="true" data-id="1">Item 1
        <ul>
            <li data-id="1.1">Item 1.1</li>
            <li data-id="1.2">Item 1.2</li>
            <li data-id="1.3">Item 1.3</li>
        </ul>
    </li>
    <li data-id="2">Item 2
        <ul>
            <li data-id="2.1">Item 2.1</li>
            <li data-id="2.2">Item 2.2</li>
            <li data-id="2.3">Item 2.3</li>
        </ul>
    </li>
    <li data-id="3">Item 3</li>
</ul>

<script>
    $(document).ready(function() {
        $("#treeview").kendoTreeView({
            select: function(e) {
                alert($(e.node).data("id"));
            }
        });
    });
</script>

Does this fit your case?
