The aggregates field is currently available only for kendoTreeListFooterTemplate:

https://www.telerik.com/kendo-angular-ui/components/treelist/aggregates/#toc-aggregating-flat-data

But in some scenarios, the aggregates need to be displayed inside the headers as well. Please provide the aggregates field in the kendoGridCellTemplate.

So far the only approach where this can be achieved is to use manual aggregation and some custom code:

   <ng-template kendoTreeListCellTemplate let-dataItem>
                    {{dataItem.name}} - <strong> {{ data.aggregates.name.count }} employee(s)</strong>
</ng-template>

Currently, the TreeList allows users to move rows using drag and drop. However, the available programmatic intervention options are quite limited. There is only one event triggered after a row is dropped, which restricts our ability to perform specific actions at different stages of the drag and drop process. For example, we are unable to prohibit certain rows from being dropped. We have certain business rules on what items are allowed on which level. So, we need to check these rules before the drop occurs.

In contrast, the TreeView component provides greater control and flexibility in this regard, offering additional intervention points and events.

Could these additional events be added to TreeList in the same way as for TreeView? We would greatly benefit from this feature.

Provide an option to set a default value for the parentId field just like the defaultValue of the Kendo UI for jQuery TreeList:

Thank you

Please provide built-in expandRow() and collapseRow() methods.

Thank you

Hi, Team!

As of now, the TreeList component does not have a designated property that allows the developers to modify its sizing. Similarly to the Grid, I would like to ask for the implementation of such a property. 

Hello,

we need a new feature in the angular treelist component that can join the neighboring cells (horizontally and vertically) with the same content

example:

Hi,

It would be a good addition to the component if there is an option to span specific rows of the column in the TreeList component. Table example:

Thank you for your consideration.

Provide sticky column feature, the same as in Grid:

https://www.telerik.com/kendo-angular-ui/components/grid/columns/sticky/

Autosize on treelist with locked columns does not work

When the width of the grid exceeds the column lengths, you would expect autosize to expand and fill the rest of the space evenly.

Hi,

Please add a multiSortKey option to the TreeList component as well. There is currently such option only for the Grid:

thanks

Please add a feature that allows to create the footer template only for specific nodes. 

Thanks
