Hello Team,

Please refer this DoJo - http://dojo.telerik.com/@SaravanaMS/utINiRUq

We have a dropdowntree component added in a grid and when we collapse the dropdowntree options - dropdowm box stays at top.

Steps to reproduce - 

1. open all options from top to bottom 

2. collapse the option from bottom to top

3. once the top option is collapsed - dropdown box stays at top

Bug report

Regression introduced in R1 2020.

Reproduction of the problem

Reproducible in the demo.

1. Focus the DropDownTree.
2. Click the "Check all" checkbox.

Current behavior

The DropDownTree items are not checked. The issue is reproducible only if the checkbox is clicked. Clicking its label, or checking the checkbox with the keyboard (Space key) checks all items as expected.

Expected/desired behavior

All items are checked.

Environment

• Kendo UI version: 2020.1.219
• jQuery version: x.y
• Browser: [IE, Edge(Spartan) ]

It would be nice to have the functionality to dynamically switch tagNodes, this feature would help sort out the issue of expanding the dropdown if many selections have been made .i.e.

It should show like the image below instead

It would also be great to add the feature to auto-select the parent's children and their sub children if the parent is checked.

The workaround for these issues is available on  this dojo

Bug report

Unexpected change event triggering when using value() method of remote datasource DropDownTree with checkboxes and autoBind false

Reproduction of the problem

1. Run the following Dojo
2. Click on Load button to set the value of the Child item

Current behavior

Script runs through datasource read else, then through datasource read if and then DropDownTree's change event is fired.

NOTE: if there is no setTimeout or if the two nodes are loaded at the same time with no if else clause, then the issue is not reproducible.

Expected/desired behavior

DropDownTree's change event is not fired, when value() method is called.

Environment

• Kendo UI version: 2019.2.619
• Browser: [all]

Similar fixed issue: #4352

I use the below template to render nodes (so that root nodes do not have a checkbox), but when I click checkAll button the root node(s) content are also displayed as selected

You should provide an event to custom handle this behavior and ignore nodes unselectable

 .Checkboxes(setting => setting
                                                .CheckChildren(true)
                                                .Template("# if (item.level() > 0) { #" +
                                                            "<input type='checkbox' #= item.checked ? 'checked' : '' #>" +
                                                            "# item.text = item.SymptomName #" +
                                                            "#}else{#" +
                                                                "# item.text = item.LocationName #" +
                                                            "#}#"
                                                )
                                )

Keep up the awesome work !

Hi,

I have a DropDownTree with checkboxes, like so:

                    $("#cbxWorkZones").kendoDropDownTree({
                        placeholder: "Select Work Zones...",
                        dataTextField: "name",
                        dataValueField: "id",
                        valuePrimitive: true,
                        checkboxes: true,
                        checkAll: true,
                        autoClose: false,
                        autoBind: false,
                        dataSource: data.workZones
                    });

I get an instance of it like so:

    var wz = $('#cbxWorkZones').data("kendoDropDownTree");

I evaluate value and get this: []  meaning, there are no values selected.

Then I set its value like so:

    wz.value(["8", "6"]);

After setting the values, I evaluate value again, and I get this: [8,6,8,6]

Why are the values duplicated?

Thanks!

Juan
