The treeview should allow more than one node to be selected at the same time.

When drag and drop is enabled in a treeview, dragging a node from one treeview to another adds it to the other tree and removes it from the first. It would be nice if the move could also be specified as a 'copy' (leaving the source untouched).

It would be great, if I get a feature to allow to drag multiple selected nodes from treeview to drop to Treelist nodes. I need this by using MVC telerik not Kendo

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.

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

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)

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

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
Duplicated

The DataBound event fires for each node that has children, but does not fire for the bottom-level nodes.  This is the same behavior as the hierarchical data source Change event.  It fires for each datasource level, which includes a parent and its children, but does not fire for the children unless they also have children.

Since there also is no event that triggers when the entire tree is loaded, there is no good way to perform an operation on each TreeView node after the TreeView is refreshed.  The only way is to traverse the tree after using a timeout to wait for the datasource to load.  This is a brittle arrangement.  Incident 1041348 provides a test case for this scenario.

A recent update added the Checkbox widget that uses a novel set of CSS and HTML elements to stylize the checkbox in the browser.  This style is not automatically applied to the TreeView widget's checkboxes.

It would be very nice to have the TreeView checkboxes stylized to maintain a consistent look and feel across widgets:

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

It will be great if kendo has a single operation to ensure node visibility upon selection, i.e. automatically do all of these 3 under the hood:
1) select the node
2) expand collapsed parents
3) scrollIntoViewIfNeeded

Something like:
     treeview.select(node, true);

Add the ability to search for partial text in tree view as well as search for other properties not just by name or UID. When searching, often times you are doing so without remembering exact names or UID. Exact match is pretty much useless in this case. Also being able to search for other properties of the nodeData would be extremely helpful. For example, I have an item type property which I would like to search on.

Please make the drag/drop ignore property accessible when treeview drag/drop is enabled.  It would be helpful even if it was something static like k-ignore-drag.  This would allow parts of my template to not initiate the drag/drop.

Thanks

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
