Using setDataSource method on a working DropDownTree, with same initial settings leads to not working clea button and not expanding a collapsed node. 

Dojo: https://dojo.telerik.com/uLUNudEJ 

Steps (clear button):

1. Open dojo and check that everything works correctly

2. Click reload button (calls setDataSource)

3. Clear all button does not work and cannot deselect the item from the tag's clear button.

 

Steps (expand):

1. Open dojo and open popup to see everything expands as expected

2. Click reload

3. Open popup

4. The last (initially collapsed) node cannot be expanded.

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.

Bug report

The DropDownTree validation error message appears when the widget gets opened. The message appears before the user is able to select an item. The behavior is not consistent with the validation of the rest of the widgets, such as DropDownList, for example.

Reproduction of the problem

  1. Open the Dojo example
  2. Expand the DropDownTree

Scenario 2: DropDownTree in a Form - Dojo

Current behavior

The DropDownTree is validated on open, thus it is marked as invalid before the user has the possibility to select an item.

Expected/desired behavior

The validation of the DropDownList should be consistent with the rest of the widgets. It should be validated when it is focused out

Bug report

The DropDownTree's refresh API method re-renders only the noDataTemplate and the footerTemplate. The nodes are not re-rendered.

Reproduction of the problem

Current behavior

Only the noDataTemplate and the footerTemplate are re-rendered.

Expected/desired behavior

The method should also re-render the nodes, similarly to the DropDownList's refresh method, which re-renders its items.

Hi
I have a problem with the DropDownTree component.
From a remote data source type json I am getting a tree with two levels of data but it only shows the first level.

Code:

$("#dropdowntree").kendoDropDownTree({
	dataSource: {
		transport: {
			read: {
				url: "/api/getData",
				type: "POST",
				dataType: "json",
				contentType: "application/json; charset=utf-8"
			}
		}
	},
	checkboxes: true
});

Response:

[
	{
		text: "Furniture", expanded: true, items: [
			{ text: "Tables & Chairs" },
			{ text: "Sofas" },
			{ text: "Occasional Furniture" }
		]
	},
	{
		text: "Decor", items: [
			{ text: "Bed Linen" },
			{ text: "Curtains & Blinds" },
			{ text: "Carpets" }
		]
	}
]
But if I set the data from a js object it shows the two levels correctly
$("#dropdowntree").kendoDropDownTree({
	dataSource: {
		data: [
			{
				text: "Furniture", expanded: true, items: [
					{ text: "Tables & Chairs" },
					{ text: "Sofas" },
					{ text: "Occasional Furniture" }
				]
			},
			{
				text: "Decor", items: [
					{ text: "Bed Linen" },
					{ text: "Curtains & Blinds" },
					{ text: "Carpets" }
				]
			}
		]
	},
	checkboxes: true
});
Previously it worked, I don't know which version of kendo stopped working.
How can I solve it with a single request to the server?

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.

Expected/desired behavior

All items are checked.

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.

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

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:

 

https://runner.telerik.io/fullscreen/uwoBEKiT/2

 

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

 

Regards
