Add persistSelection property in the Kendo UI TreeList similar to the persistSelection in the Kendo UI Grid:

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/persistselection

 

 

 

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.

### Bug report

The change event is not triggered, when a checkbox is selected in the Keno UI TreeList widget.

### Reproduction of the problem

1) Create a checkbox selectable TreeList widget;

2) Select/check any of the checkboxes;

3) The change event is not triggered;

4) Unselect/uncheck any of the checkboxes;

5) The change event is triggered;

A Dojo sample for reproduction: https://dojo.telerik.com/EWUFOhip

### Expected/desired behavior

The change event should be triggered, when a checkbox is selected in a checkbox selectable TreeList widget.

### Environment

* **Kendo UI version:**2021.1.119
* **jQuery version:** 1.12.4
* **Browser:** [all]

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.

When aggregate sum few child's rows the parent row not calculate only at the bottom of the treelist grid.

First I thought there is a problem in my code, after search I found this post.

I have fixed the data type but as I said the parent not include in the sum group only at the bottom total.

Thanks

The TreeList reorderable functionality does not work when using a different field name for the parentId (not the default parentId).

Reproduction

In the example below the treelist with parentId: ''parentId" works well when you drag Carla under Ashley. But in the second treelist, Carla disappears

Hi Team,

I'd like to request the functionality to drag the column header of a Kendo UI TreeList and dropping it in a grouping section to make the TreeList Groupable. 

Similar to the Kendo UI Grid:

 

Thank you!

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):

### 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:

### 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

1. Set locked content in the TreeList.
2. The height is not calculated correctly.

Dojo sample for reproduction:

 https://dojo.telerik.com/EsobuqAH

### Environment

* **Kendo UI version:** 2020.1.219
* **jQuery version:** 3.4.1
* **Browser:** [Chrome | IE | Edge] 

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:

https://dojo.telerik.com/IQuHuNej

 

Great work on this control boys.... I reckon it needs Filter Row, Multiple Column Sort, Paging to make it consistent with the grid.

Scotty

I would like to use drag and drop on treeList to reorder rows (with same parent) like on treeView or at least to have same events (drag, dragstart, dragend, drop), where I'll be able to change behaviour.

Is there any support for checkbox columns in the treelist to behave the same way as the kendoTreeView checkboxes? 

(ie, checking or unchecking parent should check/uncheck all children? and checking or unchecking children should update parent check state (possible indeterminate states))

Bug report

ColumnMenuOpen event not triggered in Kendo UI TreeList.

Reproduction of the problem:

1. Open the https://dojo.telerik.com/aWiKabiw demo.
2. Open the column menu and verify that the ColumnMenuOpen event is not triggered.

Environment:
* **Kendo UI version**: 2020.2.513
* ***jQuery version*: 1.12.4
* **Browser:** [all] 

The grid dataBinding event exposes useful information like the action, based on which I can implement my logic.

The treeList equivalent only has the sender, making it virtually useless.

The functionality of treelist with drag&drop without autosync and without batch saving, at the end of the drop the change is not saved.

There is available a hack in the forum

https://www.telerik.com/forums/drag-and-drop-not-hitting-update-action

For me this is a bug because I would expect for the change with drop to be automatically saved but it seems that for your support it is not. I understand that all the other changes are saved by the user with a button but the drag&drop does not have a button for it.

So if you do not want to implement this at least add a warning in the drag&drop demos page about this and provide the hack from the forum link or something so that others can know that they have to apply the hack in order for the drag&drop change to be automatically saved.
