Hi Team,

I would like to request when paging in the TreeList to include the prior parent node in the new page.  For example, if there is a parent node that has 30 child nodes, and the pageSize is 15, show the parent node on page 1 and 2.  

Thanks!

Bug report

When there is a frozen column in the TreeList, not all the columns are resized correctly on double-clicking on the resize handler.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/Aticudup
2. Double-click between the LastName and Position columns -> the LastName column is resized based on the content.
3. Double-click between the Position and Ext columns

Current behavior

The Position column is not resized and a scrollbar may appear depending on the width of the screen

Expected/desired behavior

The behavior when clicking on the drag handler should be the same for all the columns. In the described scenario the Posiiton column should be resized as well.

Environment

• Kendo UI version: 2024.1.130
• Browser: [all ]

Bug report

When an item is expanded and the refresh icon is displayed due to an issue with the sent request (for example а failed request), the icon gets replaced by a loading indicator once another item is expanded.

Reproduction of the problem

1. Open the Dojo example - https://dojo.telerik.com/ebehaBAL
2. Expand the 'First Expand' item.
3. Expand the 'Last Expand' item.

Current behavior

After expanding the second item, the refresh icon from the first item disappears and a loading indicator replaces it.

Expected/desired behavior

The refresh icon should still be displayed and should not be replaced by a loading indicator.

I needed the hierarchal datasource so I used a treelist instead of a grid. I am using a lot of special features; locked columns, columnMenu. But I found that the treelist does not support all the same things the grid does.

Here are a few I found:

•   columnMenu: false does not work
•   grid resizeColumn() method does not exist on treelist
  

 

Kendo UI Treelist currently only supports pagination using pager. This is confusing for user when the hierarchy is spread across multiple pages. On the other hand if Treelist supports Virtual Scrolling (client side paging) like we see in Grid, the user will get more clarity of the hierarchical structure. 

Hi, I found a bug which is reproduced in following dojo: https://dojo.telerik.com/OcaTEbOk
I need to disable row which meet some conditions after dataBound event. To do that class 'k-disabled' is added to each tr in grid and it works fine. Now, I collapse node with disabled rows and expand it again. Even nodes are indeed disabled but odd nodes are enabled (k-disabled class is removed from these rows). Check example provided above. Try to collapse 'Constance Vazquez' node (there are only disabled rows there) and expand again. 

Please consider adding persis selection functionality to the TreeList. Such is available in the Grid:

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

Hi Team,

I'd like to request the functionality to filter only parent records and not the child's records.

Thank you!

The Kendo TreeList has an incorrect colspan value for the headers when the first column is hidden and the file is exported to Excel.

Dojo:

https://dojo.telerik.com/IFuCutaV/4 

The names of the headers are not displayed in the correct positions.

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!

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

 

 

 

### Bug report

When custom classes are set via the headerAttributes of the column and the showColumn is called, the predefined classes are wiped away

### Reproduction of the problem

1. Set custom class via headerAttributes.

2. Call the showColumn method.

3. Custom classes are wiped away.

Dojo sample for reproduction:

https://dojo.telerik.com/UJalevej

### Expected/desired behavior

The classes should be retained after the method is called.

### Environment

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

Bug report

Ticket ID: 1489274

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!

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.

Feature enhancement
Scrolling on TreeList locked columns is slow/jumpy

Reproduction of the problem
https://dojo.telerik.com/IcoyOcAK

- Open above dojo

- Expand First Name column items until a vertical scrollbar appears 

- Scroll with the mouse over the locked column (First Name)

Current behavior
Scrolling is slow an jumpy

Expected/desired behavior
Scrolling shall be smooth, the same as when scrolling over the non-locked columns

Steps to reproduce the bug:

1. Navigate and run the DOJO example here--> https://dojo.telerik.com/uFIWePam

2. Click on "Export to Excel"

3. Either download the file or just click Cancel/Close the download dialog box.

4. Now expand the first node in the list.

5. Appears that all the other nodes get expanded.

 

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

Hi Team,

I'd like to request for the Kendo UI TreeList have the ability to export to Word.  

Thanks!
