Drag & Drop multiple nodes in a treeview from one parent to another.

If i have lots of children nodes that i need to move from one parent to another I have to do one at a time... it will be usefull to select multiple nodes and 

in one single drag&drop do the shift.

Thanks

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.

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.

I am using Kendo tree view with drag and drop feature enabled in it. I am facing problem with it in my Samsung note 10 mobile. Where a normal swipe on the phone with the tree view is picked up as a drag and drop. Is there a way to differentiate between these two.

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.

Hi there,

We noticed an issue with our Numeric TextBox after a recent upgrade on Chrome.  We're currently on Version 73.0.3683.86 (Official Build) (64-bit), the latest version at the time of writing.  Our setup has a grid using a TreeView as an editor template.  The TreeView, in turn, uses a NumericTextBox inside its item template.  I've prepared a working demo that illustrates the issue.  If you click on the last column of the grid, expand the TreeView and click on one of the NumericTextboxes, you will see that it loses the focus as soon as you click on it.  As a result, it's impossible to input anything into those fields.  Any other browsers don't have this issue.

https://dojo.telerik.com/ukuTAYOB/4

We had a lot of issue reports from our clients this week so we're pretty sure it's a recent update from Chrome.  Please let me know if you need further clarification.  This is a fairly serious issue for us as it's affecting one of the main functionalities of our web application.  If you can provide a temporary workaround before the proper fix comes out, that'd be great.

 

Regards,

Brian Roth

The expand Icon of the treeview node is being reset, if another node is dropped above/below it.

To reproduce this behavior you can take the Drag and Drop demo of the treeview. In the initial state the "Furniture" node is expanded. If you take the "Decor" node and drop it above the furniture node, the "Furniture" node stays expanded but the icon changes to collapsed.

ADMIN EDIT: workaround: https://dojo.telerik.com/@bratanov/aLigiWaz

The issue does not manifest with R3 2019 SP1.

You can also monitor it in the following GitHub issue: https://github.com/telerik/kendo-ui-core/issues/4820

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.

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.

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

When using datasource read action, the read action sends an id with to the read action for each node in the treeview. 

Could be nice if it was possible to send this id with the signalR read method. We need this Id in our solution to load the tree correctly.

So an option to use the node id in signalR would be very usefull.

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

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.

Expose originalEvent in the dragstart event like it is done in dragEnd event. This gives the posibility to check if the ctrl key is pressed en prevent dragging if ctrl key should be considered.

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.
