Hello!

I wonder if there is a possibility to create an option ala "select all", but customize it to selecting only second-level nodes or nodes with specified ids?

I'm using a dropdowntree editor on a grid column. The bound field is a list of objects.

• How would I prevent the top-level from getting selected when using check boxes with CheckAll true? I only want the second level items.
• Conversely, how would I select the top level if any of the second level items are checked?

Ex. I would not want 18' checked here, just the two children on the 2nd level:

Editor:

function equipmentEditor(container, options) {
        let ds = new kendo.data.HierarchicalDataSource({
            data: _equipmentTypes,
            schema: {
                model: {
                    children: "Items"
                },
            },
        });

        $("<input data-bind='value: EquipmentTypes'/>")
            .attr("name", options.field)
            .appendTo(container)
            .kendoDropDownTree({
                checkboxes: {
                    checkChildren: true
                },
                checkAll: true,
                autoWidth: true,
                dataTextField: "Description",
                dataValueField: "Code",
                dataSource: ds,
                autoClose: false,
                tagMode: "single",
            });

_equipmentTypes data used in dataSource:

Posted object:

"EquipmentTypes": [
            {
                "Code": "17'",
                "Description": "17'",
                "Items": [
                    {
                        "Code": "T17.DUMP",
                        "Description": "17' Dump Trailer",
                        "Items": [],
                        "id": "",
                        "index": 0,
                        "checked": true,
                        "_level": 1,
                        "_tagUid": "b13353ee-cbd3-4226-8b4c-080d4ea775e4"
                    }
                ],
                "index": 0,
                "expanded": true,
                "checked": true,
                "_level": 0,
                "_tagUid": "c0785273-c8bd-4a18-8598-de5d7ba6c16e"
            },
            {
                "Code": "T17.DUMP",
                "Description": "17' Dump Trailer",
                "Items": [],
                "id": "",
                "index": 0,
                "checked": true,
                "_level": 1,
                "_tagUid": "b13353ee-cbd3-4226-8b4c-080d4ea775e4"
            }
        ],

How to get the data item from the node in the select event?

Scroll of  Dropdown tree  is not working when navigate through keyboard's down arrow.

We have similar implementation like below link. and in the provided link scroll bar is also not working when we navigate trough keyboard.

Link: https://dojo.telerik.com/oVoboJeq 

Please  let us know solution/workaround for it. 

Thanks!!

I like to bind to this JSON below. De JSON should fill the dropdownlist. The first item would have a value of 0 and a text of Unknown.

{
    "0": "Unknown",
    "1": "Not executed",
    "2": "Not reported",
    "3": "Executed and Reported",
    "4": "Not to be executed",
    "select": null,
    "table": null
}

But somehow the dropdownlist only accepts JSON like:

Hi, 

i have a drop down tree created, as shown in the attachment below

i need to checked all the checkboxes by default. How to do this?

In the change event, is there any way to get the underlying data item of the selected node?

For a treeview control we can get the data item with something like this in the select event:

var dataItem = myTree.dataItem(e.node);

However, there's no "node" attribute in the change event for DropDownTree.

How do we do this?

Hi,
