When attempting to use the filter function on a TreeListDataSource, the linked TreeList control reports that are no records to display regardless of what filter is entered.  This includes attempts to clear/reset the filters using an empty object/null and behaves the same regardless of whether serverFiltering is enabled.

The TreeListDataSource object contains the expected records.

The TreeList control doesn't allow for a fixed row of aggregates at the bottom of the control. I would like to have the option to enable a row of "Grand Total" aggregates that are aggregates of the whole data set. This row would be fixed at the bottom of the control and wouldn't be scrollable. This is functionality that the Kendo Grid has that isn't available in the Kendo TreeList.

When the Kendo UI Treelist is horizontally scrollable and a filter is applied which returns no items, the scrollbar disappears. Therefore, if the column is one of the hidden ones, it would be impossible to navigate to it in order to clear the filter. 

A Dojo sample for the reproduction of the issue:

The TreeList databound event is not fired when pageable is used and an item is collapsed. Here is a dojo to replicate the case. Run the sample and collapse Guy.

Hi 

Noticed an issue with Tree list pagination, after applying filter.Please find attached screen recorder for the same.

Same issue i had in my application, which was able to reproduce using the  Telerik Demo's from https://demos.telerik.com/kendo-ui/treelist/index

--When it first load and minimize/collapse the parent it correctly shows page 1 as available pages.

-->Then Apply filter as shown in recorder, which then shows pages up to 5 where there were no records to display from page 2 to 5. Which is quite misleading.
 
Please find attached recorder.

Remove dependence on templates to allow for easier native display and alignment for grid conversion to treelist.

Include the headerTemplate option for multi-column headers in TreeList similar to  the Grid widget feature (note Contact Info column).

Changes to edit cells are lost when clicking the next cell or other rows in the TreeList.

  1. Create TreeList that uses both InCell editing and drag-and-drop movement.
  2. Click a cell to edit the text.
  3. Type a few characters.
  4. Click any other cell in the TreeList.
  5. The edited cell exits edit mode and the text reverts to its original value.

Dojo Example adapted from TreeList InCell Editing demo (also attached):

Feeling excited to see Kendo UI treelist is now paginated. It would be great if the same can have virtual scroll.

Hi, 
it would be really helpful to have an event like beforeEdit (present in the Grid) in order to eventually cancel the edit event for certain rows.

For example: I want the user to be able to edit only nodes without children and, as today, i cannot cancel the edit event.

Hi.

I'd like the ability to bind a TreeList to SignalR, much like the Grid:
https://demos.telerik.com/kendo-ui/grid/signalr.

Thank you.

Hi.

I would like the ability to specify a template for the toolbar in a TreeList, much like the ability in the Grid.

Thank you.

Some times, when we expand children, we want to see the grand children on top then children and then the parent. in my case it has to do with the date they were created and I want to show the newest first.

In the treelist, I would appreciate to have a loading component when the user performs actions (sort, filter). It is very disturbing, as the user doesn't know that the tree list is loading and he has to wait. Moreover this feature already exists for flat grids.

Kendo tree list does not support column resize for touch devices. It would be very helpful if this can be considered since our application supports touch devices and without column resizing feature in kendo tree list columns it is very difficult to read the text in tablets, etc
