I have the following code that I am trying to use to delete an item in the database when someone clicks the delete button:
 

<script id="treeview-template" type="text/kendo-ui-template">
         #: item.name #
         <a href="javascript:void(0)" class='btn-sm btn-danger' onclick="DeleteNode(@item.id)">x</a>
 </script>
 @Html.Kendo().TreeView().Name("Categories").ExpandAll(true).Template("treeview-template").DataSource(dataSource => dataSource
.Model(model => model
.Id("id")
         .HasChildren("hasChildren")
         )
           .Read(read => read.Action("GetCategories", "Categories"))).DataTextField("name").DragAndDrop(true).Checkboxes(true).Events(events => events.Change("onChange").Select("onSelect").Check("onCheck").Collapse("onCollapse").Expand("onExpand").DragStart("onDragStart").Drag("onDrag").Drop("onDrop").DragEnd("onDragEnd"))

The issue I'm having is that the field I'm trying to pass to the function, @item.id, is causing the exception: "The name 'item' does not exist in the current context." How can I format the code so this works?

Thanks.

Laurie

Please note: I do have .TemplateId in my code rather than .Template as is in the example I gave, and it does work when I don't try to add the javascript call.

Yes it was.  For those who are interested, the correct syntax is:

<a href='javascript:void(0)' class='btn-sm btn-danger' onclick='DeleteNode(#:item.id#)'>x</a>

Visual Studio 2013 will mark the hash marks in red, and when you hover over them will tell you it is an "Invalid character," but don't let that scare you.  It works just fine.
