dataBinding

Fires before the widget binds to its data source. The event handler function context (available through the this keyword) will be set to the widget instance.

Event Data

e.sender kendo.ui.TreeList

The widget instance which fired the event.

e.preventDefault Function

If invoked, prevents the data bind action. The table rows will remain unchanged and the dataBound event will not fire.

Example - subscribing to the dataBinding event before initialization

<div id="treeList"></div>
 <script>
    $("#treeList").kendoTreeList({
      columns: [
        { field: "Name" },
        { field: "Position" }
      ],
      dataSource: [
        { id: 1, Name: "Daryl Sweeney", Position: "CEO", parentId: null },
        { id: 2, Name: "Guy Wooten", Position: "Chief Technical Officer", parentId: 1 }
      ],
      dataBinding: function(e) {
/* The result can be observed in the DevTools(F12) console of the browser. */
        console.log("dataBinding");
      }
    });
</script>

    });

    var treeList = $("#treeList").data("kendoTreeList");
    treeList.bind("dataBinding", dataBinding);
    treeList.dataSource.fetch();
