When I select initialize a kendoDropDownTree with checkboxes set to true, I experience all kinds of odd behavior visually. Inspecting the code shows that it is now a MultiSelectTree and not a DropDownTree yet there is no documentation and little support for this somewhat hidden component. I would actually prefer to have a MultiSelectTree without the checkboxes similar to a multiselect but with the grouping. 

One issue, is that it does not respect the global settings for the corner radius of the box. 

kendo.ui["DropDownTree"].fn.options["rounded"] = "none";

kendo.ui["MultiSelect"].fn.options["rounded"] = "none";

These seem to do nothing. When I guessed at "MultiSelectTree", I got a console error. 

Another issue is that the UI looks very different from the regular multiselect and it doesn't seem to apply the .k-selected class as expected. When I check a box, the aria-checked is true but the k-selected class is not applied, this makes the item remain white rather than getting the blue background like it does in a regular multi-select. Can we get some consistency there?

Expanding an element does not change the height of the k-child-animation-container. It does show on the screen, but any styling targeting the container will not work because the container does not expand to fit the content. 

I made my dropdown arrows 7px wider (k-treeview-toggle). Now the autoWidth makes the list 7px wider than the input element.

Hello,

I'm currently  creating a treeview page using kendo JQuery.

I want to make it so that when a child node is selected, the parent node is selected.

I found this page, https://docs.telerik.com/kendo-ui/knowledge-base/check-nodes-programmatically, and tried to this properties.

 var treeview = $("#tree").data("kendoTreeView");

    var bar = treeview.findByText("Bar");

    treeview.dataItem(bar).set("checked", true);

But, 'menuAuth.js:299 Uncaught TypeError: Cannot read properties of undefined (reading 'findByText')' was printed on the console.

also, parent cannot be read.

'menuAuth.js:301 Uncaught TypeError: Cannot read properties of undefined (reading 'parent')' is printed on console too.

I really need to make parent node selection.

please let me know how can I use this things.

Thanks,

Jieun

Hello, I have noticed some changes on the structure of the Treeview component after version 2024.1.319 March 18, 2024

Classes like k-group and k-in seem to have been removed completely

For example, in previous version, the structure of a Treeview component would look like this:

<ul class="k-group k-treeview-group">
	<li class="k-treeview-item">
		<div class="k-treeview-top">
		         <span class="k-treeview-leaf k-in">TEST STRING</span>
		</div>
	</li>
</ul>

while now it would look like this:

<ul class="k-treeview-group">
	<li class="k-treeview-item">
		<div class="k-treeview-top">
			<span class="k-treeview-leaf">
				<span class="k-treeview-leaf-text">TEST STRING</span>
			</span>
		</div>
	</li>
</ul>

On release notes, I did not find any particular reference on these classes being removed

So my questions are:

1. Have they been removed widely?
2. Are there any other components that may still use these classes?
3. Is there any form of documentation that contain these changes?

Thank you in advance

I have followed all the examples but nothing is overriding the default theme.  I even tried to change it in after everything is loaded inside my done routine.

Hi, with angular Kendo 14++ we lost the Icon Class. But now how I can  cutomize treeview custom drag template?

I whant to add the k-i-cancel icon on some specific node. In the pass I was using:

Then in the getDragStatus I can do the logic and push the correct icon in ngClass.

For now I remove the template because I lost all the other icon like (add, insert, ... )

Its just for visual help, because I validate the drop in the "nodeDrop" fonction.

Thanks

Is there a way to expand disabled nodes in the treeview component? There was a solution (https://www.telerik.com/forums/expand-disabled-nodes) but with the current version of kendo-ui it does not work anymore.

It seems that the expand/collapse icon is now disabled as well and it does not fire any event. Is there another solution to make this work again?

The API documentation for the TreeView shows a loadCompleted event, but I'm not seeing it in the build I'm using. 2021.3.1207

Thanks
