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).
The expandTo and expandPath methods of the TreeView do not change the data-expanded and aria-expanded attributes to "true".
After the items are expanded, their data-expanded and the aria-expanded attributes are false.
After the items are expanded, their data-expanded and the aria-expanded attributes should be set to true.
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
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.
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.
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:
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.
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: http://docs.telerik.com/kendo-ui/web/appearance-styling#checkboxes-and-radio-buttons
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.
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.
treeview filter for parent as well as child view I.e Filter by Contains ie if i'd enter the alphabet 'A' then it will shows all the word contains 'A' in parent and as well as child node
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);
