Bug report

When using a draghandle to drag a same level item below another item, it will not drop in the correct place.

Reproduction of the problem

1. Go to this Progress Kendo UI Dojo.
2. Try to drag Brian under Lillian as soon as the indicator says it's okay.

Current behavior

The item will revert back to the original position.

Expected/desired behavior

The item should be place in the expected dropped location.

Environment

With later jQuery versions, if the TreeList's toolbar is configured, and the scrollable option is set to false, the dragging indicator is misplaced. The issue does not reproduce with jQuery 1.12.3.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/hPQIFuFo/6
2. Drag a row, and observe where the dragging indicator is.

Current behavior

The dragging indicator is misplaced

Expected/desired behavior

The dragging indicator should be positioned correctly to show where the row will be dropped

Environment

jQuery: 3.7.0

Hi Team, 

I would like to request the functionality to filter by parent items, and display all associated children. 

Thank you!

When the style attribute is used to style the 'td' elements in the TreeList, the attribute is removed from the rendered markup.

Reproduction of the problem

Current behavior

The style attribute is removed.

Would like this option just like the regular grid has:

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

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. 

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.

Environment

• Kendo UI version: 2023.2.718

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
  

 

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:

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

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):

https://dojo.telerik.com/@JimmyTheChimp/UpOsAgus

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.
