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.

Steps to reproduce bug:

• Navigate to demo with Multi-columns header https://demos.telerik.com/kendo-ui/treelist/multicolumnheaders
• Click on "Edit this example" button
• On dojo edit code to add needed lib:
• <script src="https://kendo.cdn.telerik.com/2019.1.220/js/jszip.min.js"></script>

• add also toolbar: ["excel"] on config options
• Run dojo and hit export

The result has broken Headers

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.

Please add an ability to expand/collapse tab groups in treelist

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.

it would be really help full to get same footerTemplate as kendo grid has where you can get the column info plus you can get the current dataItem.

Add RowDetails to TreeList (similar to RowDetails for Grid).

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

Would like this option just like the regular grid has:
http://demos.telerik.com/kendo-ui/grid/filter-multi-checkboxes

The TreeList needs a DetailRow with DetailTemplate just like the Grid has.  The Grid does not support Hierarchial data that has more than one level of depth but the TreeList does and yet has no Detail Row.  Please add a Detail Row.

Using the dataBound event is useful for initializing 3rd party widgets within a template (such as bootstrap-toggle) or to use kendo.bind to bind controls to a model. The issue is that when other rows are expanded the internal _render event is triggered which can recreate an existing row which means that the widget reverts back to standard HTML and the binding is lost.
