How to disable draging of disabled node of tree view

[ianc]

I am trying to avoid drag and droping on disabled elements . My tree view definition is:

@(Html.Kendo().TreeView()

        .Name("treeview")

        .DragAndDrop(true)

        .ExpandAll(true)
           .Events(e => e.Drag("...").DragStart("....").Drop("...").Select("..."))

....

 .BindTo(....

               item.Text = x.Name;

               item.Id = x.Id

               item.Enabled = false;

 )

Events do some business logic for elements movement. I was trying to find on DragStart event any information about k-state-disabled class in e.sourceNode but I fail. 
Also I was trying to found any Enabled property in data source element - also did not found anything.
Could someone help with this issue ? Where is my mistake?

Hi Lukasz,


You are right, that you could get the information about the disabled node through the e.sourceNode property. Here is a sample implementation.
E.g.

function dragStart(e) {
    if ($(e.sourceNode).find(".k-state-disabled").length > 0) {
        e.preventDefault();
    }
}

Please let me know if this approach is working in the current scenario.
