Initiates the Excel export. Also fires the excelExport event.

Calling this method may trigger the built-in browser popup blocker. To avoid that, always call it as a response to an end-user action (for example, a button click).

Example - manually initiating the Excel export

<button id="export">Export to Excel</button>
<div id="treeList"></div>
        columns: [ "id", "name" ],
        dataSource: [
            { id: 1, parentId: null, name: "Jane Doe", age: 30 },
            { id: 2, parentId: 1, name: "John Doe", age: 33 }
    $("#export").click(function(e) {
        var treeList = $("#treeList").data("kendoTreeList");
