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.

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.

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.

We want Kendo Workbook to export TreeView group data to Excel. We have a situation where we need to export grouped data from TriewView as is to Excel to represent the hierarchical relationship in Excel.

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);

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)

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

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

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

:upon selecting an item, either by click or programmatically,

$(tv).scrollIntoView(item) with would bring the item into view, even in multilevel nested, hierarchical, situations.

that would be very sweet!!
I have tried JQuery.scrollTo but have had no success in nested <li>
scenarios.
thanks


item will scroll into view

I need homogenous data items for multilevels in your tree control.
Most data structures coming from our services are not homogenous.
We use the following to create a homogenous structure for the tree.
Maybe you could incorporate something like this - note that we use angular, and I use their $parse service in my implementation:

// CALLER:

          var levelDescriptors = [
            { item: "functionGroup", items: "functions" },
            { item: "this", items: null }];
          itemHierarchy = Portal.buildItemHierarchy(
            functionGroups,
            levelDescriptors,
            $parse);

// UTIL CODE:

    buildItemHierarchy: function(hierarchicalItems, levelDescriptors, $parse) {
      var hierarchicalDataItems = [];
      if(Portal.isDefined(hierarchicalItems)) {
        hierarchicalDataItems = Portal.createHierarchicalDataItems(0, hierarchicalItems, levelDescriptors, $parse);
      }
      return hierarchicalDataItems;
    },

    createHierarchicalDataItems: function(level, levelItems, levelDescriptors, $parse) {
      var levelDataItems = [];
      if(Portal.isDefined(levelItems)) {
        if(Portal.isDefined(levelDescriptors)) {
          if(level < levelDescriptors.length) {
            for(var i=0; i<levelItems.length; i++) {
              // extract datasource for current level.
              // create an associated node data item.
              var levelItem = levelItems[i];
              var levelDescriptor = levelDescriptors[level];
              var item = levelItem;
              if(levelDescriptor.item !== "this") {
                item = $parse(levelDescriptor.item)(levelItem);
              }
              if(Portal.isDefined(item)) {
                var levelDataItem = Portal.createNodeDataItem(item);
                levelDataItems.push(levelDataItem);
                // extract children for current level.
                // create associated (child) node data items.
                var items = $parse(levelDescriptor.items)(levelItem);
                if(Portal.isDefined(items)) {
                  var itemsLevel = level + 1;
                  levelDataItem.items = Portal.createHierarchicalDataItems(
                    itemsLevel,
                    items,
                    levelDescriptors,
                    $parse);
                }
              }
            }
          }
        }
      }
      return levelDataItems;
    },

    createNodeDataItem: function(item) {
      return {
        id: item.id,
        text: item.name,
        dataSource: item,
        expanded: false,
        items: []
      };
    },

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

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).
