Rebuild TreeView with new data

[Igor]

Hello,

I want to rebuild the Treeview with new data. I use this code:

$(#treview)

    .removeClass('k-treeview')

    .empty();

$(#treeview).kendoTreeView({

    dataSource: getNewdata(),

    select: onNodeSelect

});

The tree is rebuild well but the function onNodeSelect is called two times if I select a node.
Is there a way to  clear also event handling for select?

Hello Igor,

Theoretically, using the treeview API should be cleaner:

    var kendoTree = treeview.data("kendoTreeView"); 

    // clear the treeview and unbind handlers
    kendoTree.remove(".k-item");
    kendoTree.unbind("select");
    
    // bind new data and add handler
    kendoTree.append(getData());
    kendoTree.bind("select", function() { alert("rebound select"); }); 

However, we discovered several bugs while we were testing this approach, which have been fixed in the attached JavaScript.

Kind regards,
