Save/sync HierarchicalDataSource (treeview), having kendo.data.Node models, does not work properly: 
- though setting a kendo.data.Node model, the view model is not applied on all items(e.g. setting the field type), it's applied only on level 0 items
- if modifying a single field on a lower/higher level(e.g. 5th level) in a hierarchycal data source, the entire hierarchy is sent to the server (instead of a single item, probably more than 100 might be sent, thought a single field, on a single item was change)
- when deleting some items, the deleted items are sent as an array (which is ok), but when updating it sends the entire herarchy(see above)
- when creating a lower level item, the create command is not send to the server; only an update on level 0 item (see above)
- there no consistency on what's sent to the server on add/update/delete (e.g. add: level 0 - create; other levels: update on level 0 parent - parent/"grandparent"/...)
- when calling the sync method to save any changes, the model is not updated on succesful save (similar to what's on grid - DataSource), e.g. if server generates an id for the item
- when moving an item from a node to another, destroy command is called, not an update
- on the documentation it says it inherits everything from DataSource, but it seems they do not work properly

The TreeView control does work on mobile, and on android the performance is acceptable, on iPhones however it suffers from the same problem that onclick suffers from, sometimes a click registers as a move instead of a click so you have to click many times to get a branch node to open. It would be better if it could use the kendo touch events (the equivalent of data-click)

I am using TreeView and many other Kendoui HTML controls in my WebPart and I am finding it very fast and good looking, just I am facing only issue while sorting the nodes because I am creating HTML element ul dynamically with multiple nodes and then applying KendoUITreeView()
Please provide sort as standard method on TreeView.

Hi Team,

I would like to request the functionality to move a node from within a folder to the outside of it by dragging it horizontally to the left. 

Thank you!

Hi Team,

I'd like to request the autoScroll functionality with Keyboard Navigation for the Kendo UI TreeView so if the user navigates below or above the page, the focused item will scroll into view.

Thank you!

Kendo TreeView should return a promise.

When using treeview and setting loadOnDemand: true when you call expand on a node that has not been loaded there's no way to know when the loading has completed.

Returning a promise will allow the developer to know when the expansion has completed.

It would be nice to have more control over the item templates. ie, be allowed to more easily do stuff like:

  • Make the item non-selectable, or only selectable by a child element.
  • Make the item drag-and-droppable only via a grip element.
  • Make the item template display as a block, not inline.

I have incorporated the Kendo UI Treeview in my application by following closely the demo code, but Treeview does not work. The tree is shown on the web page, but the branches do not open and close when clicked on. Also, instead of the folder icon shown in the example, I just get the normal bullet points you would expect from a "<ul>" structure.

Currently you have to run this snippet to force only 1 selection from a tree. https://www.telerik.com/forums/allow-only-single-checkbox-to-be-checked-at-a-time#sky4SuHN70Cbrnl-6cNnhg

I would suggest this be added as a configuration option of the tree. something like singleSelect: true

Release 2020.R2

Bug report

The expandTo and expandPath methods of the TreeView do not change the data-expanded and aria-expanded attributes to "true".

Reproduction of the problem

  1. Open this Dojo, which demonstrates two different TreeViews using the two methods.
  2. Inspect the expanded items.

Current behavior

After the items are expanded, their data-expanded and the aria-expanded attributes are false.

Expected/desired behavior

After the items are expanded, their data-expanded and the aria-expanded attributes should be set to true.

As explained at http://www.telerik.com/forums/paging-a-treeview, paging in a treeview is not support. However, this feature would be highly useful for nodes that have hundreds of children, when the user may not want to way for all of them to be loaded or displayed at one time.

See by contrast Webix pager for trees - http://docs.webix.com/api__link__ui.tree_pager_config.html

I'm not sure if a treeview component is planned for R1 2018 but a treeview react component would be very useful.

Hi,

 

There is an accessibility issue regarding MAS 4.2.1 - Object Information.

Using keyboard navigation and screen reader (Windows Narrator),

While the focus is on expanded tree item (with inner children), screen reader should not read all the children information in one go, it should read one by one.

See the attached video.

Can you help please?

 

Thanks,

Michal.

It would be really helpful to have a tree view search.

Search - highlights all results for given text. User can select by clicking on the node
