Bug report

TreeList shows wrong total and paging when we expand or collapse a row after filtering.

Reproduction of the problem

1. Go to TreeList demo link - https://demos.telerik.com/kendo-ui/treelist/index
2. On "Position" column apply filter with value "VP, Engineering"

3. After filtering only 4 rows will be visible, and the number of rows at the bottom of grid shows "1 - 4 of 4 items".
4. Now collapse the second row. Notice that the total at the grid bottom changes to "1 - 15 of 4 items" which is wrong.

Expected/desired behavior

The shown message within the pager has to be "1 - 4 of 4 items" instead of "1 - 15 of 4 items".

Environment

* **Kendo UI version:** 2019.3.1024

If the read() method of the data source of the TreeList widget is called, the pager is not refreshed. It retains the only pages and information.

Reproduction of the problem

1. Update the data source of the TreeList widget.

2. Notice that the pager is not completely refreshed.

A Dojo sample for reproduction:

https://dojo.telerik.com/aHIPUgIz

Hi Team,

• Click the Export button in TreeList

Hi Team,

I would like to request the Kendo UI TreeList to have an optional setting to show aggregate values at the parent row based on the children's aggregates.  

Thank you!

Export to PDF feature is exporting the PDF as single page and the PDF is not printer friendly. Please add Multi page support.

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.

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, 
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.

Tanks

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

### Bug report

The height of the locked content in Chrome with jQuery version 3.4.1 (all jQuery versions after 3.1.1) is not calculated correctly.

### Reproduction of the problem

2. The height is not calculated correctly.

### Bug report

When the footerTemplate option of the TreeList is specified for a column that is part of a multi-column header configuration, the template is not rendered.

### Reproduction of the problem

1. Set a footerTemplate option for the nested column. Dojo sample for reproduction:

https://dojo.telerik.com/iKisAZaS/16

### Environment

* **Kendo UI version:** 2020.1.219
* **jQuery version:** 1.12.4

We use the treelist to create our commercial offers. Each offer can have a node with lots of children at the same level.

The user should have the possibility to add a node at the same level of the selected item.

Now it is only possible to add a parent or a child in the first position and after that sorting the treelist. It is very confusing if the node list is quite long.

 

It will be nice to have two methods like inserAfter(selectedRow) or inserBefore(selectedRow) as for example the methods you have for the treenode
