Bug report
DropDownTree as a row editor does not clear chips when x button is clicked. Select All option does not select items

this.dataSource.data()  does not have items

Regression with 2022.1.119

Reproduction of the problem
Open this Dojo example - https://dojo.telerik.com/oXizEQac

Open Name column row filter DropDownTree

Select All shall select all items. Clearing items shall clear them

Environment
Kendo UI version: 2022.1.119 or newer
Browser: [all]

In the latest version of Kendo, the DropdownTree control no longer shows the placeholder when there's nothing selected when you use checkboxes.

Here's a dojo showing that it does not work in the latest version: Kendo UI Snippet | Kendo UI Dojo (telerik.com)

If you revert to the last Kendo version, you'll see that the placeholder is working as expected. 

Hi,

When using the dropdown tree on safari using the bootstrap themes when the page has scrollbars and clicking on the dropdown the page scrolls up, even though there is available space:

 

Please see this Dojo which replicates the issue:

Open the above URL in Safari, chick on the dropddown and the page scrolls up and the dropdown is no longer visible.

Bug report

If you prevent the DropDownTree's close event, the k-animation-container-shown class is removed from the popup.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/UrALIJOK/3
2. Open the DropDownTree
3. Open the browser console and inspect the k-animation-container element
4. Blur the DropDownTree

Current behavior

The k-animation-container-shown class is removed from the popup element.

Expected/desired behavior

The k-animation-container-shown class should be preserved.

Environment

• Kendo UI version: 2023.3.1010
• Browser: [all]

Enhancement

Currently, when checkboxes are enabled, the selected items cannot be sent to a remote end-point via form submit. Research possible workarounds for the senario - rendering an additional input elements, parsing or other suitable approach that allows submitting the value of the widget.

Bug report

Pressing the clear button of the DropDownTree does not change the component's value in the change event.

Reproduction of the problem

1. Open this Dojo - https://dojo.telerik.com/aREzEWaK/13
2. Open the browser console
3. Select an item
4. Press the clear button

Current behavior

The value is the same as before pressing the button

Expected/desired behavior

The value should be an empty string after pressing the clear button

Environment

• Kendo UI version: 2023.1.117
• Browser: [all]

Bug report

Reproduction of the problem

Dojo example: http://dojo.telerik.com/ePEPAtEl/3
Two scenarios:

1. The DropDownTree's height is set to "auto" and there are enough nodes in the embedded treeview, so that the when the popup shows up a vertical scrollbar appears. In Chrome and IE, when the scrollbar appears the page is scrolled down automatically, which causes the popup to close.

2. height is not set explicitly in the DropDownTree (remove the setting from the dojo example). If the browser window is resized so that there isn't enough space for the whole popup to be displayed, on the popup showing up, the same behavior as in 1. is observed.

Current behavior

The popup closes automatically.

Expected/desired behavior

The popup remains open.

Environment

• Kendo UI version: 2020.3.915
• jQuery version: x.y
• Browser: [Chrome 85 | IE11 ]

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) ]

Add the parent method for DropDownTree that functions the same as the parent method in  the TreeView widget.

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
