Bug report

When the sortable option is disabled, the title in the header is not wrapped in span element with 'k-column-title' class.

Reproduction of the problem

1. Open the Dojo and inspect the titles - https://dojo.telerik.com/hKCCsAOU

Current behavior

Rendering with sortable enabled:

The filtering icon and title have enough space:

Rendering with sortable disabled:

filtering icon overlaps the title in case of long text:

Expected/desired behavior

The rendering should be identical. The header title should be wrapped in a span element with 'k-column-title' class

Workaround for fixing the overlapping issue:

<style>
    .k-grid-header .k-filterable{
      padding-right: calc(1.42857143em + 14px);
    }
  </style>

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 

[Dojo]

Environment

* **Kendo UI version:** 2020.3.915

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.

### Bug report

Treelist column's filterable property is applied to the wrong field when column locking and a multi-column header is applied.

Reported in: 1446991

### Reproduction of the problem

https://dojo.telerik.com/@Mearaj_6303/EDuhUlOG

### Current behavior

The Filter from "Position" is hidden.

### Expected/desired behavior

The Filter from "Phone" is hidden.

Hi,

Using Fluor´s commercial purchase, we were able to get latest kendoui.for.jquery.2022.3.913.commercial, previously we were using v2019.1.220

After migration, I see that when using a kendoTreeList, that has a column template, it does not properly render the template content.

Template to render:

<script id="actions-template" type="text/x-kendo-template">

    <div id="actions-revenue" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="delay-input-screen-pbwbs-overview pl-1" id="delayButton-#: id #" style="display: none;">

        <i class="fas fa-calendar-alt" /></a>

    </div>

    <div id="actions-edit" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="edit-input-screen-pbwbs-overview pl-1" id="editButton-#: id #" style="display: none;">

        <i class="fas fa-pencil-alt" /></a>

    </div>

    <div id="actions-delete" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="delete-input-screen-pbwbs-overview pl-1" id="deleteButton-#: id #" style="display: none;">

        <i class="fas fa-trash-alt" /></a>

    </div>

</script>

Rendered template (good one) with previous version v2019.1.220

<td role="gridcell" style="white-space: nowrap;">

    <div id="actions-revenue" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="delay-input-screen-pbwbs-overview pl-1" id="delayButton-3" ><i class="fas fa-calendar-alt"></i></a>

    </div>

    <div id="actions-edit" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="edit-input-screen-pbwbs-overview pl-1" id="editButton-3" ><i class="fas fa-pencil-alt"></i></a>

    </div>

    <div id="actions-delete" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="delete-input-screen-pbwbs-overview pl-1" id="deleteButton-3" ><i class="fas fa-trash-alt"></i></a>

    </div>

</td>

Rendered template (buggy one) after upgrading to version 2022.3.913

<td role="gridcell" aria-describedby="d51133dd-fb81-4e68-9d56-4d61aab7f81a" class="" style="white-space: nowrap;">

    <div id="actions-revenue" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="delay-input-screen-pbwbs-overview pl-1" id="delayButton-3" >

        <i class="fas fa-calendar-alt"></i></a><i class="fas fa-calendar-alt">

    </i></div><i class="fas fa-calendar-alt">

    <div id="actions-edit" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="edit-input-screen-pbwbs-overview pl-1" id="editButton-3" >

        <i class="fas fa-pencil-alt"></i></a><i class="fas fa-pencil-alt">

    </i></div><i class="fas fa-pencil-alt">

    <div id="actions-delete" ng-show="options.displayPeriod =='MONTHLY'">

        <a class="delete-input-screen-pbwbs-overview pl-1" id="deleteButton-3" >

        <i class="fas fa-trash-alt"></i></a><i class="fas fa-trash-alt">

    </i></div><i class="fas fa-trash-alt">

</i></i></i></td>

As we can see in the original template there are icons wrapped in anchors, previous version rendered the template ok, but new version scrambles this tags…

I have also been playing in the Dojo and this seems to be the case.

Regards….

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.

Bug report

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

1. Open the Dojo - https://dojo.telerik.com/@NeliK/ulIZuKEG and inspect the

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.

Can you implement the global columns menu that is available in the Grid?

For example:

$("#treeList").kendoTreeList({
    toolbar: [
      "columns" // default built-in button to open the global columns menu
    ]
   ...
});

Hi Team,

I would like to request for the Kendo UI TreeList to have a column.resizable property similar to the Kendo UI Grid.  

Thank you!

Hi Team,

I would like to request a way to allow the Kendo UI TreeList to be editable with the Kendo UI Editor.  For example, it should allow the Editor to use the insertUnorderedList or insertOrderedList. Those lists would be indented, and the text would return back to a hierarchical style.  Currently, this does not occur.

Replication

1. Go to this Progress Kendo UI Dojo.
2. Click the plus for a new level.
3. Click on first cell to open editor.  
4. Change content to an unordered list. 
5. Then, remove it.

Thank you!

Bug report

In the TreeList, the row colors are not consistent with other technology divisions, e.g. Angular. With the Classic Silver theme, the rows are not consistent regarding the alternating background colour approach. Additionally, in the Default theme, the rows are not as differentiated as they should be by design.

Note: the issue appears to be related to the k-treelist-group class on the elements in the TreeList.

Workaround: https://dojo.telerik.com/ORIjOcAB/3

Reproduction of the problem

1. Open the TreeList Overview demo with Classic Silver theme.

Current behavior

The rows' background color are not consistent in regard to alternative background colors.

Expected/desired behavior

The rows' background colors should be consistent with the design.
