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.

The dropdown tree is very useful. 

I have a suggestion to improve this, which would be highly appreciated by my customers:

Add a suggest possibility, the same as the suggest possibility that already is available on the combobox.

People start to type in the search box, most of time finding the one option they need, than they first have to select the option (mouse or arrows, plus enter). It would be nice if the result (when it is one result) is already selected and they should have only to press enter.

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?

Currently the scenario where both filtering and checkboxes.checkChildren are enabled is not supported. This is a very useful feature especially when the dropdown list is long.

Please Implement Cleaner "Fully Loaded" Event Instead of Multiple onDataBound Checks as per recommended per this approach:  https://docs.telerik.com/kendo-ui/knowledge-base/dropdowntree-fully-loaded

That works fine, but if I have multiple DropDownTree elements on the page, this is a lot of extraneous code. Could this not be encapsulated within the library with a true event?

Perhaps it could be something like "contentLoaded" or "treeeInitialized". 

 

In my case I would then use it to fulfill a Promise or other actions.

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.

Allow other widgets to cascade from the DropDownTree through the cascadeFrom option.

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.

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 !

In cases when we have loadOnDemand set to true and we want to populate the value of the DropDownTree initially we need a way to check if this value is part of the available options. One possible solution is adding a valueMapper function similar to the one use in virtualization scenarios.

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
