Hello,
We found a bug in the latest version of Kendo related to the reordering columns in Treelist when inside a Grid DetailTemplate
See the Dojo below to replicate the problem:
https://dojo.telerik.com/exotEsej
Expand the detail row under a grid row and attempt to drag one of the treelist column titles to the left or right and note that an error is thrown.
Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')
Let us know when you have a workaround for this as it prevents us from promoting this version of Kendo to our production environment.
Thank you,
Brad Garner
In a out of the box popup edit, the update/cancel buttons are to the left, should be to the right for consistency with grid. Add class k-actions-end to the div with k-edit-buttons as done in grid.
I am using bootstrap-v4 css file.
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
Incell edit mode of the Kendo UI TreeList requires 2 clicks to enter edit mode. The issue can be replicated only when any of the columns have a template and the widget is used in AngularJS environment.
Reproduction of the problem
1. Create a TreeList widget, set the incell edit mode, and set a template for any of the columns.
2. Edit one cell and directly click on the next one - it requires 2 clicks to open for edit.
Sample for reproduction:
https://dojo.telerik.com/OGOkODos
Environment
* **Kendo UI version:** 2020.2.617
* **jQuery version:** 1.12.4
* **Browser:** [all]
Bug report
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
Expected/desired behavior
Refresh the pager whenever the data source of the TreeList is refreshed.
Environment
* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all]
Setup a Treelist with paging
edit set to popup
get "Maximum call stack size exceeded" error after update
I removed the paging and it works as expected
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!
apply a row template to the TreeList !
Hello,
We have a grid of tasks and each row has a detail's pane (hierarchy) that shows, when expanded, a tree list of sub-tasks.
If you attempt to delete a tree list node (not the last) it will delete the node correctly, but will trigger the grid's to prompt the user to make sure the item should be deleted or not (which is NOT normal). But when this is shown, it is already too late to Cancel has the tree list has already deleted the item. Users don't understand why they are given a chance to prevent the deletion, but it does not work.
So in short, we want the tree list, when the users deletes a node, to not trigger (i.e. to prevent) the grid's item deletion.
Here is a dojo that shows what happens:
https://dojo.telerik.com/APaXoRuR
Please let me know if you need more information,
Regards,
Eric.

Feeling excited to see Kendo UI treelist is now paginated. It would be great if the same can have virtual scroll.
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.
